Zwichnięcie rzepki

Zwichnięcie rzepki
Objawy

Zwichnięcie rzepki (luxatio patellae) to przemieszczenie rzepki poza jej anatomiczne położenie w rowku międzykłykciowym, najczęściej w kierunku bocznym, prowadzące do uszkodzenia tkanek stabilizujących, zwłaszcza przyśrodkowego więzadła rzepkowo-udowego (MPFL). Uraz ten dotyczy głównie młodych, aktywnych osób w wieku 14-25 lat i objawia się ostrym bólem, widoczną deformacją kolana, obrzękiem, zasinieniem oraz niemożnością pełnego wyprostowania kończyny. Diagnostyka obejmuje badanie RTG w celu oceny położenia rzepki i wykluczenia złamań oraz rezonans magnetyczny (MRI) do oceny uszkodzeń tkanek miękkich i chrząstki stawowej. W fazie ostrej stosuje się protokół RICE oraz farmakoterapię przeciwbólową i przeciwzapalną, a w kolejnych tygodniach wdraża się fizjoterapię ukierunkowaną na przywrócenie zakresu ruchu i wzmocnienie mięśni stabilizujących staw kolanowy.

Definicja i charakterystyka zwichnięcia rzepki

Zwichnięcie rzepki (łac. patellae/” title=”luxatio patellae” class=”to-tag” data-termid=”101162″>luxatio patellae) to stan, w którym rzepka (patella) przemieszcza się poza swoje prawidłowe położenie w pionowym rowku stawu kolanowego. Najczęściej rzepka przemieszcza się w kierunku bocznym (na zewnątrz kolana). Podczas tego urazu może dojść do rozciągnięcia lub rozerwania tkanek łącznych, które utrzymują rzepkę w prawidłowej pozycji, szczególnie przyśrodkowego więzadła rzepkowo-udowego (MPFL – medial patellofemoral ligament)¹².

Zwichnięcie rzepki występuje stosunkowo często, szczególnie u młodych, aktywnych osób w wieku 14-25 lat. Jest to uraz, który może powstać w wyniku bezpośredniego urazu, upadku, lub nieprawidłowego ruchu skrętnego kolana. Niektóre osoby mają anatomiczne predyspozycje zwiększające ryzyko wystąpienia tego urazu, takie jak dysbalans mięśniowy czy wiotkość więzadeł³⁴.

Objawy zwichnięcia rzepki

Objawy zwichnięcia rzepki są zazwyczaj wyraźne i następują bezpośrednio po urazie. Do głównych objawów należą:

Natychmiastowe objawy bólu i deformacji

Intensywny ból kolana – pacjent odczuwa silny, ostry ból w przedniej części stawu kolanowego, często opisywany jako ból zlokalizowany „wewnątrz rzepki”. Ból jest szczególnie nasilony przy próbie poruszania kończyną lub obciążenia jej⁵⁶.

Słyszalne lub wyczuwalne „pęknięcie” lub „przeskoczenie” – w momencie zwichnięcia rzepki pacjent często słyszy charakterystyczny dźwięk przypominający pęknięcie lub przeskoczenie, któremu towarzyszy uczucie przemieszczenia się rzepki⁷⁸.

Widoczna deformacja kolana – rzepka jest widocznie przemieszczona na zewnętrzną stronę stawu kolanowego, co powoduje zmianę wyglądu kolana – pojawia się guz lub wybrzuszenie na bocznej (zewnętrznej) stronie kolana⁹¹⁰.

Ograniczenia ruchomości

Niezdolność do prostowania kolana – zwichnięta rzepka uniemożliwia pełne wyprostowanie kończyny, co sprawia, że noga pozostaje w pozycji zgięciowej¹¹¹².

Trudności z poruszaniem się – pacjent często nie jest w stanie chodzić, stać ani obciążać kończyny. Kolano może mieć tendencję do „uginania się” lub „zapadania” przy próbie obciążenia¹³¹⁴.

Uczucie niestabilności kolana – pacjent odczuwa, że kolano jest niestabilne, „chwiejne” lub że może się „załamać” przy obciążeniu¹⁵¹⁶.

Reakcja zapalna i obrzęk

Gwałtowny obrzęk – bezpośrednio po zwichnięciu rzepki występuje szybko narastający obrzęk stawu kolanowego spowodowany wynaczynieniem krwi oraz reakcją zapalną. Obrzęk może być znaczny i utrzymywać się przez kilka dni¹⁷¹⁸.

Zasinienie (wylew krwawy) – w miejscu urazu może pojawić się siniak lub widoczne zasinienie skóry, które zazwyczaj rozwija się w ciągu kilku godzin lub dni po zwichnięciu¹⁹²⁰.

Ciepłota i zaczerwienienie – okolica kolana może być cieplejsza w dotyku i zaczerwieniona, co jest wynikiem reakcji zapalnej²¹.

Objawy mechaniczne

Uczucie „zatrzaskiwania” lub „blokowania” kolana – pacjent może odczuwać, że kolano się zatrzaskuje lub blokuje podczas ruchu, co jest spowodowane nieprawidłowym ułożeniem rzepki²²²³.

Trzaski lub trzeszczenia – przy próbie poruszania kolanem mogą być słyszalne lub wyczuwalne trzaski czy trzeszczenia²⁴²⁵.

„Rozchwianie rzepki” – po zwichnięciu rzepka może być wyczuwalnie bardziej ruchoma niż normalnie, co określane jest czasem jako „rozchwianie rzepki” (hypermobile patella). Pacjent może mieć wrażenie, że rzepka przesuwa się zbyt swobodnie na boki²⁶²⁷.

Przebieg zwichnięcia rzepki

Spontaniczne nastawienie rzepki

W wielu przypadkach zwichnięta rzepka może spontanicznie powrócić na swoje miejsce, szczególnie podczas prostowania kończyny. Takie samoistne nastawienie rzepki nie oznacza jednak, że nie doszło do uszkodzenia tkanek miękkich otaczających staw kolanowy. Nawet jeśli rzepka wróciła na swoje miejsce, konieczna jest ocena lekarska w celu wykluczenia dodatkowych urazów²⁸²⁹.

Jeśli rzepka nie wróci na swoje miejsce samoistnie, konieczne jest jej nastawienie przez lekarza, często z zastosowaniem znieczulenia miejscowego lub ogólnego³⁰.

Faza ostra po zwichnięciu

Bezpośrednio po zwichnięciu i nastawieniu rzepki pacjent doświadcza silnego bólu, znacznego obrzęku oraz ograniczenia ruchomości kolana. W tej fazie zwykle niemożliwe jest obciążanie kończyny i pacjent wymaga pomocy przy poruszaniu się³¹³².

W fazie ostrej zalecane jest stosowanie protokołu RICE (Rest – odpoczynek, Ice – lód, Compression – ucisk, Elevation – uniesienie kończyny) oraz leków przeciwbólowych i przeciwzapalnych³³³⁴.

Faza podostrego zdrowienia

W ciągu kilku dni do tygodnia po urazie obrzęk i ból zwykle zmniejszają się, choć nie ustępują całkowicie. W tym okresie pacjent zaczyna stopniowo obciążać kończynę, początkowo z pomocą kul lub ortezy stabilizującej staw kolanowy³⁵³⁶.

W fazie podostrej często rozpoczyna się fizjoterapia, której celem jest przywrócenie zakresu ruchu w stawie kolanowym, zmniejszenie obrzęku i bólu oraz zapobieganie zanikowi mięśniowemu³⁷.

Czas powrotu do pełnej sprawności

Pełny powrót do sprawności po zwichnięciu rzepki zależy od wielu czynników, w tym od ciężkości urazu, wystąpienia dodatkowych uszkodzeń oraz zastosowanego leczenia. Przeciętny czas rekonwalescencji wynosi:

Powrót do codziennych aktywności: 6-8 tygodni³⁸³⁹
Powrót do aktywności sportowej: 3-4 miesiące (w przypadku leczenia zachowawczego) lub 6 miesięcy i więcej (w przypadku leczenia operacyjnego)⁴⁰⁴¹

W przypadku poważniejszych urazów lub po leczeniu operacyjnym czas ten może być znacznie dłuższy i wynosić od 6 miesięcy do roku⁴².

Ryzyko nawrotów

Po pierwszym zwichnięciu rzepki istnieje znaczne ryzyko nawrotu urazu. Szacuje się, że ryzyko ponownego zwichnięcia wynosi od 15% do 60%, w zależności od czynników takich jak wiek pacjenta, anatomia stawu kolanowego oraz zastosowane leczenie⁴³⁴⁴.

Każde kolejne zwichnięcie zwiększa ryzyko następnych, gdyż struktury stabilizujące rzepkę ulegają osłabieniu. Z czasem, przy powtarzających się zwichnięciach, ból może być mniej intensywny, ale nie oznacza to, że uraz jest mniej poważny – przeciwnie, może to świadczyć o postępującym uszkodzeniu struktur stabilizujących staw⁴⁵⁴⁶.

Powikłania i następstwa zwichnięcia rzepki

Konsekwencje krótkoterminowe

W krótkim okresie po zwichnięciu rzepki pacjent może doświadczać trudności związanych z ograniczoną mobilnością, bólem oraz obrzękiem. Utrudnia to codzienne funkcjonowanie i może wymagać czasowego ograniczenia aktywności zawodowej, szkolnej czy sportowej⁴⁷.

Nawet po ustąpieniu ostrych objawów, przez pewien czas może utrzymywać się uczucie niestabilności kolana, dyskomfort podczas dłuższego siedzenia, wchodzenia po schodach czy kucania⁴⁸.

Konsekwencje długoterminowe

W dłuższej perspektywie nieleczone lub nawracające zwichnięcia rzepki mogą prowadzić do:

Chronicznej niestabilności rzepki – powtarzające się zwichnięcia powodują rozciągnięcie struktur stabilizujących rzepkę, co skutkuje przewlekłą niestabilnością stawu⁴⁹⁵⁰
Uszkodzeń chrząstki stawowej – każde zwichnięcie może powodować uszkodzenie chrząstki pokrywającej powierzchnie stawowe, co z czasem może prowadzić do jej degeneracji⁵¹⁵²
Przedwczesnych zmian zwyrodnieniowych – powtarzające się urazy stawu zwiększają ryzyko rozwoju choroby zwyrodnieniowej stawu kolanowego (osteoarthritis) w młodszym wieku⁵³⁵⁴
Ograniczeń funkcjonalnych – nawracające zwichnięcia mogą prowadzić do przewlekłego bólu, ograniczenia aktywności fizycznej, trudności w wykonywaniu codziennych czynności oraz konieczności rezygnacji z uprawiania niektórych sportów⁵⁵⁵⁶

Badania diagnostyczne po zwichnięciu

W celu oceny stopnia uszkodzeń po zwichnięciu rzepki oraz zaplanowania odpowiedniego leczenia, lekarz może zlecić następujące badania:

Badanie RTG – podstawowe badanie obrazowe pozwalające ocenić położenie rzepki oraz wykluczyć ewentualne złamania⁵⁷⁵⁸
Rezonans magnetyczny (MRI) – bardziej szczegółowe badanie umożliwiające ocenę stanu więzadeł, chrząstki stawowej oraz innych tkanek miękkich, które mogły ulec uszkodzeniu podczas zwichnięcia. MRI pozwala również zidentyfikować czynniki ryzyka niestabilności rzepki⁵⁹⁶⁰

W przypadku nawracających zwichnięć mogą być przeprowadzone dodatkowe badania w celu oceny anatomii stawu kolanowego i zidentyfikowania predyspozycji do niestabilności rzepki⁶¹.

Specyficzne objawy u różnych grup pacjentów

Zwichnięcie rzepki u dzieci i młodzieży

Zwichnięcia rzepki są szczególnie częste u dzieci i młodzieży w wieku 14-20 lat, zwłaszcza u osób aktywnych fizycznie. W tej grupie wiekowej objawy mogą być podobne jak u dorosłych, jednak ryzyko nawrotów jest znacznie wyższe⁶²⁶³.

U młodych pacjentów, szczególnie u tych z otwartymi strefami wzrostu kości, leczenie wymaga szczególnej uwagi, aby nie zaburzyć dalszego rozwoju układu kostno-stawowego⁶⁴.

Szacuje się, że około 20% dzieci i nastolatków, którzy doznali zwichnięcia rzepki, rozwija zmiany zwyrodnieniowe stawu kolanowego przed 20. rokiem życia⁶⁵.

Pierwsze vs. nawracające zwichnięcie

Pierwsze zwichnięcie rzepki jest zwykle najbardziej bolesne i traumatyczne dla pacjenta. Towarzyszą mu intensywny ból, znaczny obrzęk oraz wyraźne ograniczenie funkcji stawu⁶⁶⁶⁷.

W przypadku nawracających zwichnięć objawy bólowe mogą być mniej nasilone ze względu na rozciągnięcie struktur stabilizujących staw. Nie oznacza to jednak, że uraz jest mniej poważny – przeciwnie, każde kolejne zwichnięcie powoduje dodatkowe uszkodzenia stawu i zwiększa ryzyko rozwoju zmian zwyrodnieniowych⁶⁸⁶⁹.

Pacjenci z nawracającymi zwichnięciami często doświadczają przewlekłego uczucia niestabilności kolana, lęku przed ponownym zwichnięciem (tzw. „apprehension sign”) oraz ograniczenia aktywności fizycznej⁷⁰⁷¹.

Częściowe zwichnięcie vs. całkowite zwichnięcie

Częściowe zwichnięcie rzepki (subluksacja) charakteryzuje się przemieszczeniem rzepki bez jej całkowitego wypadnięcia z rowka międzykłykciowego. Objawy są zwykle łagodniejsze niż przy całkowitym zwichnięciu i obejmują: uczucie niestabilności kolana, ból w przedniej części stawu, trzeszczenia lub przeskakiwania podczas ruchu oraz lekki obrzęk⁷²⁷³.

Całkowite zwichnięcie rzepki powoduje wyraźne przemieszczenie rzepki poza rowek międzykłykciowy, najczęściej na zewnętrzną stronę stawu. Objawy są znacznie bardziej nasilone: intensywny ból, wyraźna deformacja kolana, znaczny obrzęk, niezdolność do poruszania kończyną oraz zablokowanie kolana w pozycji zgięciowej⁷⁴⁷⁵.

Częściowe zwichnięcia rzepki mogą powracać częściej niż całkowite zwichnięcia, ale mają mniejszy wpływ na codzienne funkcjonowanie. Objawy częściowego zwichnięcia mogą ustąpić w ciągu kilku dni, podczas gdy rekonwalescencja po całkowitym zwichnięciu może trwać tygodnie lub miesiące⁷⁶.

Podsumowanie progresji objawów

Zwichnięcie rzepki jest urazem, który charakteryzuje się specyficznym przebiegiem i sekwencją objawów:

Bezpośrednio po urazie: ostry, intensywny ból, słyszalne lub wyczuwalne przeskoczenie rzepki, natychmiastowa niezdolność do obciążania kończyny i widoczna deformacja kolana⁷⁷⁷⁸
W ciągu pierwszych godzin: narastający obrzęk, zwiększenie bolesności, ograniczenie ruchomości stawu, niezdolność do wyprostowania kolana⁷⁹⁸⁰
Po 1-3 dniach: utrzymujący się obrzęk, rozwijające się zasinienie, niewielka poprawa w zakresie bólu przy odpowiednim leczeniu, choć nadal znaczne ograniczenie funkcji⁸¹
Po 1-2 tygodniach: stopniowe zmniejszanie się obrzęku i bólu, możliwość delikatnego obciążania kończyny (często z pomocą kul lub ortezy), poprawa zakresu ruchu⁸²⁸³
Po 4-6 tygodniach: większość pacjentów może powrócić do normalnych, codziennych aktywności, choć nadal może występować dyskomfort przy intensywnym wysiłku⁸⁴⁸⁵
Po 3-4 miesiącach: możliwy powrót do aktywności sportowej przy prawidłowym przebiegu rehabilitacji, choć niektórzy pacjenci mogą wymagać dłuższego okresu rekonwalescencji⁸⁶⁸⁷

Ważne jest, aby pamiętać, że nawet po ustąpieniu ostrych objawów, ryzyko nawrotu zwichnięcia pozostaje podwyższone. Dlatego kluczowe znaczenie ma odpowiednia rehabilitacja mająca na celu wzmocnienie mięśni stabilizujących staw kolanowy oraz stosowanie się do zaleceń lekarskich dotyczących ograniczenia określonych aktywności⁸⁸⁸⁹.

W przypadku nawracających zwichnięć lub utrzymujących się objawów niestabilności rzepki, może być konieczne leczenie operacyjne w celu przywrócenia stabilności stawu kolanowego⁹⁰⁹¹.

#1 Overview: Dislocated kneecap – InformedHealth.org – NCBI Bookshelf
https://www.ncbi.nlm.nih.gov/books/NBK561511/
A dislocated kneecap is extremely painful. When it happens, the kneecap almost always comes out on the outer (lateral) side of the knee. Usually it causes a tear in the joint capsule and the ligament that stabilizes the kneecap on the inner (medial) side of the knee, known as the medial patellofemoral ligament or MPFL. These injuries make the knee swell up. […] When a kneecap is dislocated, it might make a popping sound. The dislocated kneecap can usually be seen clearly through the skin, which can be frightening. […] If you have already dislocated your knee in the past, it might hurt less and not swell.
#2 Kneecap Dislocation & Treatment – Mayo Clinic Health System
https://www.mayoclinichealthsystem.org/hometown-health/speaking-of-health/whats-going-on-with-my-kneecap
If your kneecap pops or slides to the outside of your knee, you’ll definitely know that something’s going on. Typically, that „something” is a partial or full dislocation, which means the kneecap, also known as the patella, has slipped partly or all the way out of its groove over the knee joint. […] When the kneecap dislocates, it’s painful and the knee area may swell. Whether it happens from an acute or chronic situation, dislocation can damage the cartilage of the groove that the kneecap sits in or the cartilage underneath the kneecap. […] Acute or chronic dislocation indicates you have a stretched or torn medial patellofemoral ligament, or MPFL, a tough band of tissue that connects to the inside of the kneecap and prevents it from sliding to the outside of the knee. […] The first time your knee dislocates â unrelated to an injury â it may slide back into place on its own. However, you should see an orthopedic specialist who can evaluate if there has been any injury to the cartilage and determine your risk for dislocations happening again. If there isn’t any cartilage damage, the orthopedic specialist may order physical therapy to strengthen your hip and quadricep muscles. This can help overcome any stretch in the MPFL ligament and stabilize your kneecap, as well as decrease the risk of arthritis over time. […] Recovery from MPFL reconstruction may take several months before you’re able to return to normal activities and regain your range of motion. Overall recovery for more complex surgeries may take four to six months.
#3 Patella Dislocation – How Long is Recovery Time? | Jeremy Burnham, MD
https://www.jeremyburnhammd.com/patella-dislocation-dislocated-kneecap/
A dislocated kneecap is a relatively common injury, particularly among young athletes. Symptoms of patella dislocation include knee pain, swelling, and instability. […] The most common symptom of patella dislocation is knee pain. If you have a patella dislocation, you will likely feel a sharp pain in your knee. Your knee may look deformed and feel unstable. You may also have difficulty straightening your leg. You may also feel a pop or snap at the time of injury. Other symptoms include: […] Recovery from patella dislocation typically takes several weeks. Depending on the severity of the injury, return to sports is usually assessed at 6-8 weeks. […] A patella dislocation is a serious injury. It occurs when the patella, or kneecap, pops out of place. This can happen due to a fall, a direct blow to the knee, or sudden twisting motion. Patella dislocations are most common in young people aged 15-25 years old.
#4 Dislocated Kneecap (Dislocated Patella) (for Parents) | Nemours KidsHealth
https://kidshealth.org/en/parents/dislocated-kneecap.html
A dislocated kneecap is when the bone in the front of the knee called the kneecap or patella slides out of place. […] Common symptoms of a dislocated kneecap or dislocated patella (peh-TELL-uh) include: feeling like the knee buckled or gave out, sudden, severe pain and swelling, a bump noticed on the outside of the knee. This is the kneecap that is out of place, the knee is held in a bent position, bruising around the knee. […] A dislocated kneecap can happen to any child or teen who has a blow or twist to the knee. Some kids have conditions that make them more likely to dislocate the kneecap. These include things like some leg muscles being stronger than others or loose ligaments (bands of tissue that hold bones together at joints). […] After dislocating a kneecap, kids and teens must stay out of sports and other physical activities for a few weeks. Most kids can return to these in about 4-6 weeks with therapy and exercises to build strength. Some kids might need to also use a supportive knee wrap or athletic brace during sports for a while. Your care team will let you know when your child is ready.
#5 Dislocated Kneecap (Patella Dislocation): Symptoms & Recovery
https://my.clevelandclinic.org/health/diseases/21633-patellar-dislocations
A dislocated kneecap (patella dislocation) occurs when your kneecap pops sideways out of its vertical groove at your knee joint. Its usually caused by force, from a collision, a fall or a bad step. A dislocated patella is painful and will prevent you from walking, but its easy to correct and sometimes corrects itself. […] Patellar dislocation symptoms may include: An audible pop, Buckling of your knee, Intense knee pain, Effusion, Bruising at your knee, Locking of your knee, Inability to walk, The kneecap is visually out of place. […] Like any dislocation, a dislocated kneecap is painful and debilitating until you correct it. But a dislocated patella will sometimes correct itself. […] Recovery time for a dislocated kneecap depends on the severity of your injury and method of treatment.
#6 Patellar dislocation – Wikipedia
https://en.wikipedia.org/wiki/Patellar_dislocation
Symptoms Knee is partly bent, painful and swollen. […] Often the knee is partly bent, painful and swollen. The patella is also often felt and seen out of place. […] People often describe pain as severe and being „inside the knee cap”. The leg tends to flex even when relaxed. In some cases, the injured ligaments involved in patellar dislocation do not allow the leg to flex. […] Recurrence after an initial dislocation occurs in about 30% of people.

#8 Dislocated Kneecap: Symptoms & Treatment | Jackson Clinics
https://thejacksonclinics.com/the-case-of-the-wandering-kneecap/
Swelling is a common response to a dislocation as fluid builds up in the joint. This can make the knee look visibly larger and feel stiff or uncomfortable. The swelling can also restrict your range of motion, making it difficult to fully bend or extend the knee. […] The edges of the kneecap may feel tender or sore to the touch, especially if the surrounding ligaments have been strained or torn. This tenderness is often accompanied by pain when pressure is applied to the kneecap or the joint is moved. […] One of the most telltale signs of kneecap dislocation is the sensation of the patella popping out of place. You may feel a sharp pain followed by a clicking or snapping feeling as the kneecap moves back into its groove. […] In more severe cases, the patella may completely dislocate and remain stuck outside of its normal position. This can make the knee look visibly deformed and may require medical intervention to move the kneecap back into place. […] It’s essential to remember that full recovery from a kneecap dislocation can take several months. […] The body needs time to heal, and rushing the process can lead to reinjury or prolonged instability.
#9 Diagnosis and treatment for kneecap patella dislocation
https://os.clinic/conditions/knee/kneecap-patella-dislocation/
A dislocated kneecap occurs when the patella (kneecap) that sits over the front of the knee comes out of its groove at the end of the thigh bone (femur), coming to rest on the outside of the knee joint. This can cause stretching or tearing to the supporting ligaments and tendons. […] Normally, the kneecap glides smoothly over a groove in the joint when you bend or straighten your leg but if the kneecap is dislocated you may be unable to bend or straighten your leg. A dislocated kneecap is a common injury that can take around 6 weeks to heal. If you have dislocated your kneecap once it is far more likely to dislocate in the future. […] If you have dislocated your kneecap you may experience: Obvious distortion of the kneecap, which may look out of place or appear to be at an odd angle. Severe pain in the knee and sudden swelling and bruising. Inability to bend or straighten your leg. Being unable to walk. A painful popping sensation in your knee.
#10 Patellar Dislocation | Alexander Orthopaedics
https://alexanderorthopaedics.com/patellar-dislocation/
A patellar dislocation, also known as a kneecap dislocation, occurs when the bone that sits atop the knee (the kneecap) comes out of the groove at the knee joint. Typical signs of a dislocated kneecap include a visible distortion of the kneecap, pain and swelling, and difficulty straightening or bending your knee. Kneecap dislocation requires medical intervention and usually takes about six weeks to heal. […] Common symptoms of a kneecap dislocation include kneecap is visibly out of place, severe pain accompanied by sudden bruising and swelling, being unable to bend or straighten the knee, and an audible and painful popping sensation. […] This injury will render your leg temporarily immobile, and youâll need to seek help quickly. Patellar dislocations are considered medical emergencies.
#11 Kneecap dislocation: MedlinePlus Medical EncyclopediaLock
https://medlineplus.gov/ency/article/001070.htm
Kneecap dislocation occurs when the round-shaped bone covering the knee (patella) moves or slides out of place. The dislocation often occurs toward the outside of the leg. […] Symptoms of kneecap dislocation include: Knee appears to be deformed, Knee is bent and cannot be straightened out, Kneecap (patella) dislocates to the outside of the knee, Knee pain and tenderness, Knee swelling, „Sloppy” kneecap — you can move the kneecap too much from right to left (hypermobile patella). […] The first few times this occurs, you will feel pain and may be unable to walk. If you continue to have dislocations, your knee may not hurt as much and you may not be as disabled. This is not a reason to avoid treatment. Kneecap dislocation damages your knee joint. It can lead to cartilage injuries and increase the risk of developing osteoarthritis at a younger age. Repeat dislocations will make the condition worse and harder to treat.
#12 Kneecap Dislocations – Injuries and Poisoning – Merck Manual Consumer Version
https://www.merckmanuals.com/home/injuries-and-poisoning/dislocations/kneecap-dislocations
The dislocated kneecap looks out of place. People feel pain under the kneecap. The joint is tender and often swollen. People cannot straighten the knee and can often move the kneecap from side to side. They may be unable to walk. […] Doctors can diagnose a dislocated kneecap when they examine the knee. If the kneecap has already slid back in place, they may suspect that it was dislocated because they detect blood within the joint and the joint is tender. […] A dislocated kneecap may slide back into place on its own before people can see a doctor. However, people should still see a doctor so that the doctor can check for fractures that may have occurred during the injury.

#14 Symptoms of Kneecap Dislocation
https://www.sports-health.com/sports-injuries/knee-injuries/symptoms-kneecap-dislocation
The symptoms of a kneecap dislocation will vary based upon how the injury occurred as well as the severity of the damage to the knee joint and/or if other knee injuries are also present. In minor cases, it may be possible for an athlete to immediately resume athletic activity. In others, pain and limited mobility will be apparent. […] Primary symptoms of kneecap dislocation may include: […] Lack of mobility. If the kneecap dislocates to the outside of the knee, the leg may be stuck in a bent position, making it difficult to move. […] Knee that gives way. When putting pressure on the affected leg, the knee may give out and be unable to support one’s body weight. […] Repositioning of the patella. In moderate to severe dislocations, the kneecap will not only move away from the knee joint but will fully reposition itself to the outside of the leg.

Patellar (kneecap) dislocations occur with significant regularity, especially in younger athletes, with most of the dislocations occurring laterally (outside). When these happen, they are associated with significant pain and swelling. […] Typical symptoms include: Rapid, acute swelling. Extreme pain initially until relocation occurs. Continued pain along medial (inside) ligaments. Discoloration medially at site of ligament injury. Sense of instability and apprehension that problem will recur. […] It has been found in retrospective studies that the incidence of recurrent dislocation after the first dislocation occurs can be as high as 40 percent.
#18 Dislocated Kneecap: Symptoms & Treatment | Jackson Clinics
https://thejacksonclinics.com/the-case-of-the-wandering-kneecap/
Kneecap dislocation, or patellar dislocation, can be a painful and frustrating experience, particularly for those who lead active lifestyles. […] It happens when the patella (kneecap) shifts out of its normal position, usually moving to the outside of the knee joint. […] Knowing what to look for when it comes to a kneecap dislocation can help you get the right treatment sooner and begin your rehabilitation. […] Below are the key symptoms associated with a dislocated kneecap. […] A kneecap dislocation can cause internal bleeding, which might not be immediately visible. This bleeding leads to swelling and a sensation of tightness around the knee. […] As with any injury, bruising may develop due to the trauma sustained by the tissues surrounding the kneecap. The bruising may appear as a discoloration around the knee, indicating damage to the blood vessels underneath the skin.

A hyper-mobile patella. In instances where the patella hasnt moved away from the front of the knee but has dislocated, an individual may be able to move the patella around the front of the knee joint with an extended range of motion. Or the kneecap may simply feel out of place/not lined up. A hyper-mobile kneecap is sometimes referred to as sloppy knee. […] Pain when standing. Kneecap dislocation may cause sharp pain on the front of the knee when an individual tries to stand or put pressure on the knee joint. Over time, the pain in the kneecap will dull, but this is not necessarily indicative of healing. […] Localized tenderness. The kneecap will usually be painful to touch. […] Bruising. Bruising may appear on and around the front of the kneecap during the healing process, particularly if the injury was caused by direct impact or blunt force. […] Swelling. Swelling of the kneecap, also known as water on the knee, may occur when fluid is trapped around the kneecap following traumatic injury. This swelling may contribute to an athletes inability to move or straighten his or her leg.
#20 What Are the Signs of Kneecap Dislocation?
https://www.verywellhealth.com/kneecap-dislocation-2549592
A dislocation of the kneecap occurs when the patella comes completely out of its groove on the end of the thigh bone (femur), and comes to rest on the outside of the knee joint. […] A kneecap dislocation causes significant pain and deformity of the knee joint. The kneecap almost always dislocates to the outside of the joint. Pain and swelling are common symptoms of kneecap dislocation. Over time, bruising may also develop around and below the knee joint. […] The typical signs of a kneecap dislocation include: A painful pop in the knee, Inability to straighten the leg (held with the knee bent), Swelling and deformity of the front of the knee. […] Instability of the kneecap may result in a complete dislocation of the kneecap outside of its normal groove, or it may result in sensations that the kneecap is unstable within its groove. […] Once the MPFL is torn, it often does not heal with proper tension, and the kneecap can subsequently dislocate more easily. That is why recurrent dislocations of the kneecap can continue to occur in some patients who have this injury.

#42 Kneecap Dislocation & Treatment – Mayo Clinic Health System
https://www.mayoclinichealthsystem.org/hometown-health/speaking-of-health/whats-going-on-with-my-kneecap
If your kneecap pops or slides to the outside of your knee, you’ll definitely know that something’s going on. Typically, that „something” is a partial or full dislocation, which means the kneecap, also known as the patella, has slipped partly or all the way out of its groove over the knee joint. […] When the kneecap dislocates, it’s painful and the knee area may swell. Whether it happens from an acute or chronic situation, dislocation can damage the cartilage of the groove that the kneecap sits in or the cartilage underneath the kneecap. […] Acute or chronic dislocation indicates you have a stretched or torn medial patellofemoral ligament, or MPFL, a tough band of tissue that connects to the inside of the kneecap and prevents it from sliding to the outside of the knee. […] The first time your knee dislocates â unrelated to an injury â it may slide back into place on its own. However, you should see an orthopedic specialist who can evaluate if there has been any injury to the cartilage and determine your risk for dislocations happening again. If there isn’t any cartilage damage, the orthopedic specialist may order physical therapy to strengthen your hip and quadricep muscles. This can help overcome any stretch in the MPFL ligament and stabilize your kneecap, as well as decrease the risk of arthritis over time. […] Recovery from MPFL reconstruction may take several months before you’re able to return to normal activities and regain your range of motion. Overall recovery for more complex surgeries may take four to six months.
#43 Patella Dislocation – StatPearls – NCBI Bookshelf
https://www.ncbi.nlm.nih.gov/books/NBK538288/
Patellar instability is a spectrum of conditions ranging from intermittent subluxations to dislocation. Patients typically present with obvious deformity and an inability to extend the knee. The recurrence rate following a first-time dislocation is around 15-60%. […] Patients typically describe pain and deformity of the knee following a non-contact twisting injury, or a direct blow to the anterior or medial aspect of the knee. They often describe the knee giving way and feeling a pop, and commonly report swelling in the acute setting. In chronic cases, pain is usually anterior or anteromedial, and patients may report giving way, clicking and catching, with the symptoms being worse during flexion and kneeling. […] Physiotherapy can be necessary for as long as two to three months following an initial dislocation. Physiotherapy is vital, as if the medial retinaculum does not heal and the VMO does not adequately rehabilitate, recurrent dislocation will ensue. Studies suggest there is a 20 to 40% risk of re-dislocation, with even higher rates following a second dislocation.

[…] Everything got much better, and no further dislocations, but i have pain when trying to flex my knee fully- a very sharp pain which can be at the base of patella or inside of my knee. […] When I’m walking a lot in a day sometimes my knee gets stiff and after rest I’ll then be limping by the end of the day. […] I also cannot kneel comfortably, squat or sit back on my heels when kneeling. […] I usually ski in the winter, but I cannot manage more than an hour without pain anymore, and I’ve been too afraid to climb, which I also used to enjoy, since it happened for fear of twisting it and redislocation.

Recognizing the signs of a dislocated kneecap is crucial for timely intervention. Common symptoms include: […] If someone experiences these symptoms, it’s advisable to seek medical attention immediately. A dislocation can cause significant damage to the knee joint and surrounding tissues if not treated promptly. […] For individuals experiencing a first-time patella dislocation, the prognosis is generally positive. Most people can expect to recover fully within six weeks after treatment. […] However, chronic dislocations or those that occur due to underlying conditions can lead to longer recovery timelines and may require more extensive treatment. […] While the prognosis for first-time dislocations is good, long-term complications may arise. A dislocated patella can lead to a less stable knee joint, deteriorating cartilage, and may ultimately increase the risk of developing osteoarthritis later in life. […] Chronic instability and recurrent dislocations might necessitate further medical intervention, such as surgical stabilization of the knee joint.

When the patella dislocates, the knee undergoes a significant trauma. The patella almost always dislocates laterally (to the outside of the knee). The restraining ligament on the inside of the knee called the medial patellofemoral ligament (MPFL) almost always tears or is significantly stretched out. […] Primary treatment for a patella dislocation is conservative care unless other injuries exist (such as a loose body from a fracture within the joint) that require early surgical treatment. Your child will be treated initially with immobilization. Ice, elevation and anti-inflammatories will help to decrease swelling following the dislocation. […] Most often, a single time dislocation will not recur. However, because a dislocation often damages knee tissue, the patella often remains looser, or more unstable, than it was before the injury. As a result, the patella may dislocate again. Recurrences also are common if the dislocation was caused by an irregularity in the knee structure. If your child’s patella dislocates multiple times, or continues to be unstable despite therapy and bracing, surgery may be recommended to correct the problem.

Kneecap subluxation or dislocation may occur more than once. The first few times it happens will be painful, and you will be unable to walk. […] If subluxations continue to occur and are not treated, you may feel less pain when they happen. However, there may be more damage to your knee joint each time it happens. […] You may have had a knee x-ray or an MRI to make sure your kneecap bone did not break and there was no damage to the cartilage or tendons (other tissues in your knee joint). An MRI can also identify risk factors on why your kneecap is unstable. […] If your kneecap is damaged or unstable, you may need surgery to repair or stabilize it. Your health care provider will most often refer you to an orthopedic surgeon. […] Contact your provider if: Your knee feels unstable. Your kneecap is out of place and it can’t be put back in place.

#91 Diagnosis and treatment for kneecap patella dislocation
https://os.clinic/conditions/knee/kneecap-patella-dislocation/
A dislocated kneecap can sometimes correct itself. However you should always seek urgent medical help even if it has gone back into position as a dislocation can cause damage to surrounding ligaments and tendons. […] A dislocated kneecap will be quickly put back into position (referred to as reduction) by the consultant. This may need to be performed under local or general anaesthetic. Once the kneecap has been put back into place, you will need to rest the knee and use ice, compression and elevation to control swelling. You will normally need crutches or a knee brace while your knee is healing. Patients are generally offered physiotherapy to help them to strengthen the muscles and regain movement in the knee. […] If you experience recurrent kneecap dislocation, you may be offered surgery to tighten the muscles or reconstruct the inside ligaments. In rare circumstances you may need to have the bone cut and repositioned.
