• #1 Patellofemoral Pain Syndrome | AAFP

  https://www.aafp.org/pubs/afp/issues/2019/0115/p88.html

  Patellofemoral pain syndrome (PFPS) is one of the most common causes of anterior knee pain encountered in the outpatient setting in adolescents and adults younger than 60 years. The cardinal feature of PFPS is pain in or around the anterior knee that intensifies when the knee is flexed during weight-bearing activities. The most sensitive physical examination finding is pain with squatting. […] The differential diagnosis of anterior knee pain is extensive. PFPS is usually diagnosed using history and physical examination findings. […] The cardinal feature of PFPS is pain in or around the anterior knee that intensifies when the knee is flexed during weight-bearing activities. Patients should be asked about previous knee injuries and surgeries, current activity level, and recent changes in activity.

• #2 Physical Examination and Patellofemoral Pain Syndrome: an Updated Review

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8733121/

  Patellofemoral pain syndrome (PFPS) accounts for 25 to 40% of all knee disorders. Diagnosis of PFPS is primarily based on history and physical examination, but the findings on physical examination are often subtle and do not consistently correlate with symptoms described. […] Diagnosis of PFPS is primarily based on history and physical examination because although imaging can show signs of patellar maltracking and/or patellofemoral chondrosis suggestive of PFPS, these findings are often non-specific, and there are patients with completely unremarkable imaging who still have pain. […] However, a systematic physical examination can still call attention to factors that contribute to patellofemoral malalignment and thus be used to guide treatment. […] Recent literature has further supported Q angle (when measured utilizing a standardized protocol), crepitus, weakness of hip abductors and extensors, and weakness detected in functional testing as predictors of PFPS while finding inconsistent evidence behind lateral patellar tilt as a predictor of PFPS. The reliability of most physical examination tests alone remain low, but clustering physical examination findings may provide better sensitivities and specificities in diagnosing PFPS. Musculoskeletal US is rapidly gaining popularity, and decreased vastus medialis obliquus (VMO) volume, asymmetry in gluteus medius thickness, intra-articular effusions, and quadriceps and patellar tendon thicknesses have shown value in diagnosing those with PFPS.

• #5 Patellofemoral pain – UpToDate

  https://www.uptodate.com/contents/patellofemoral-pain-syndrome

  Patellofemoral pain (PFP) is a frequently encountered overuse disorder that involves the patellofemoral region and often presents as anterior knee pain. PFP is characterized by pain around or behind the patella that is aggravated by one or more activities that involve loading the patellofemoral joint during weight bearing on a flexed knee, and that cannot be attributed to another discrete intra-articular (eg, meniscus tear) or peripatellar (eg, patellar tendinopathy) pathology. […] The pathophysiology, diagnosis, and management of PFP are reviewed below.

  https://www.ncbi.nlm.nih.gov/books/NBK557657/

  Patellofemoral syndrome (PFS) is one of the most common causes of anterior knee pain. […] It is a diagnosis of exclusion once another intra-articular and peripatellar pathology has been ruled out. […] PFS is considered a diagnosis of exclusion once intraarticular or peripatellar pathologies are ruled out. […] The diagnosis of patellofemoral syndrome is heavily reliant on a detailed and accurate history and physical examination. […] PFS is considered a diagnosis of exclusion; therefore, one must rule out other conditions that it may mimic. […] The diagnosis of patellofemoral pain syndrome is typically a clinical one. […] If the patient fails to respond to therapy, imaging is used to rule out other causes of similar pain, such as bipartite patella, osteoarthritis, loose bodies, and occult fracture.

• #7 What Is Patellofemoral Pain Syndrome? | Summit Health

  https://www.summithealth.com/patellofemoral-pain-syndrome

  PFPS is what is known as a diagnosis of exclusion, meaning doctors rule out other conditions that could be causing the knee pain. If theyve found no evidence of other conditions, they diagnose the problem as PFPS. […] A physical exam is the cornerstone of a PFPS diagnosis. A doctor will gently manipulate the knee, asking the patient about where the pain is and how it feels (e.g., an aching pain versus a sharp pain). The physician will also try to determine if there was an acute injury or certain activity causing the pain, and when the patient feels pain most often. […] An X-ray can be helpful in ruling out other conditions. X-rays do not display soft tissue such as cartilage, tendons or ligaments well, but can show damage to the patella or femur. A magnetic resonance imaging scan can detect any damage to the patellas cartilage, indicating chondromalacia.

  The diagnosis is made as a clinical diagnosis by exclusion in the absence of other identifiable pathology such as meniscal injury, tendinopathy, bursitis, or apophysitis. A core criterion of diagnosis is pain around or behind the patella that is aggravated by at least one activity that loads the patellofemoral joint during weight bearing on a flexed knee (e.g., squatting, stair ambulation, running, or jumping). Palpation test, patellar tilt test, and eccentric step test are proposed to discriminate between PFP and other non-traumatic knee disorders, but there is no consensus on the optimal diagnostic tests, an apparent reason being the lack of a gold standard. Imaging is usually not necessary for the diagnosis or explaining the patients symptoms. […] A recent review found moderate to strong evidence that BMI/ body fat percentage, age and height/weight/limb length were not risk factors for developing PFP. The review found conflicting evidence about muscle strength as a risk factor.

• #11 Patellofemoral Syndrome ICD 10 Insights

  https://www.kneepaincentersofamerica.com/blog/patellofemoral-syndrome-icd-10

  Patellofemoral pain syndrome (PFPS) is characterized by a dull, aching pain located in the anterior retropatellar and/or peripatellar region of the knee. The diagnosis of PFPS is based on the presence of retropatellar or peripatellar pain, reproduction of pain with certain activities, and the exclusion of other conditions that may cause anterior knee pain. […] The diagnosis of patellofemoral pain syndrome (PFP), often characterized by insidious onset of poorly defined pain in the anterior retropatellar and/or peripatellar region of the knee, involves several steps. […] Clinicians should use reproduction of retropatellar or peripatellar pain during squatting as a diagnostic test for PFP. Additionally, the performance of other functional activities that load the patellofemoral joint (PFJ) in a flexed position, such as stair climbing or descent, can also be used as diagnostic tests for PFP.

  PFPS causes pain in front of the knee, just behind the kneecap. It tends to increase in a sitting position or during repeated flexion/extension movements (e.g.: go up or down the stairs). […] Then, it is essential to have a clinical examination to eliminate the main differential diagnoses of patellofemoral pain syndrome. […] Diagnosing patellofemoral pain syndrome can be difficult because of the number of possible associated conditions. […] Before radiological assessment, the clinical examination aims to reduce the possibilities. […] Medical imaging captures knee X-Rays images from front, profile, weight-bearing and then with the knees bent at 30. […] If you have knee pain, you should consult as soon as possible to get the diagnosis of patellofemoral pain syndrome. […] Every step in the diagnosis of PFPS is crucial, the questioning shouldn’t be neglected. […] After getting the diagnosis of patellofemoral pain syndrome, your general practitioner can prescribe you several treatments, which depend on your symptoms.

  Laboratory studies are not indicated for the diagnosis of PFS. Serology, joint aspiration, and related tests may be useful when alternative diagnoses are suspected. However, such investigations are not likely to provide useful information in this syndrome, as it is not a disease entity but rather a group of symptoms occurring sometimes in association with multiple factors (intrinsic and extrinsic). […] PFS is a clinical diagnosis and usually does not require imaging to diagnose and treat. Nonetheless, imaging studies may be considered for unusual presentations and for patients who are refractory to conservative management.

  Despite this distinction, the diagnosis of PFPS is typically made based only on the history and physical examination rather than on the results of any medical imaging. Therefore, it is unknown whether most persons with a diagnosis of PFPS have cartilage damage or not, making the difference between PFPS and chondromalacia theoretical rather than practical. […] Magnetic resonance imaging rarely can give useful information for managing patellofemoral pain syndrome and treatment should focus on an appropriate rehabilitation program including correcting strength and flexibility concerns. In the uncommon cases where a patient has mechanical symptoms like a locked knee, knee effusion, or failure to improve following physical therapy, then an MRI may give more insight into diagnosis and treatment.

Diagnosis of PFPS is primarily based on history and physical examination, but the findings on physical examination are often subtle and do not consistently correlate with symptoms described. […] Diagnosis of PFPS is primarily based on history and physical examination because although imaging can show signs of patellar maltracking and/or patellofemoral chondrosis suggestive of PFPS, these findings are often non-specific, and there are patients with completely unremarkable imaging who still have pain. […] However, a systematic physical examination can still call attention to factors that contribute to patellofemoral malalignment and thus be used to guide treatment. […] Recent literature has further supported Q angle (when measured utilizing a standardized protocol), crepitus, weakness of hip abductors and extensors, and weakness detected in functional testing as predictors of PFPS while finding inconsistent evidence behind lateral patellar tilt as a predictor of PFPS.

  The diagnosis is made as a clinical diagnosis by exclusion in the absence of other identifiable pathology such as meniscal injury, tendinopathy, bursitis, or apophysitis. A core criterion of diagnosis is pain around or behind the patella that is aggravated by at least one activity that loads the patellofemoral joint during weight bearing on a flexed knee (e.g., squatting, stair ambulation, running, or jumping). Palpation test, patellar tilt test, and eccentric step test are proposed to discriminate between PFP and other non-traumatic knee disorders, but there is no consensus on the optimal diagnostic tests, an apparent reason being the lack of a gold standard. Imaging is usually not necessary for the diagnosis or explaining the patients symptoms. […] A recent review found moderate to strong evidence that BMI/ body fat percentage, age and height/weight/limb length were not risk factors for developing PFP. The review found conflicting evidence about muscle strength as a risk factor.

  Patellofemoral pain syndrome is knee pain as a result of problems between the kneecap and the femur. The diagnosis is generally based on the symptoms and examination. If pushing the kneecap into the femur increases the pain, the diagnosis is more likely. […] The patellofemoral glide, tilt, and grind tests (Clarke’s sign), when performed, can provide strong evidence for PFPS. […] Various clinical tests have been investigated for diagnostic accuracy. The Active Instability Test, knee pain during stair climbing, Clarke’s test, pain with prolonged sitting, patellar inferior pole tilt, and pain during squatting have demonstrated the best accuracy. […] However, careful consideration is still needed when using these tests to make a differential diagnosis of PFPS. […] The diagnosis of patellofemoral pain syndrome is made by ruling out patellar tendinitis, prepatellar bursitis, plica syndrome, Sinding-Larsen and Johansson syndrome, and OsgoodSchlatter disease. Currently, there is not a gold standard assessment to diagnose PFPS.

Further studies, especially those that are longitudinal in design, are needed to establish the gold standard for diagnosing PFPS and what US findings are truly predictive of PFPS.

• #71 Physical Examination and Patellofemoral Pain Syndrome: an Updated Review

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8733121/

  Patellofemoral pain syndrome (PFPS) accounts for 25 to 40% of all knee disorders. Diagnosis of PFPS is primarily based on history and physical examination, but the findings on physical examination are often subtle and do not consistently correlate with symptoms described. […] Diagnosis of PFPS is primarily based on history and physical examination because although imaging can show signs of patellar maltracking and/or patellofemoral chondrosis suggestive of PFPS, these findings are often non-specific, and there are patients with completely unremarkable imaging who still have pain. […] However, a systematic physical examination can still call attention to factors that contribute to patellofemoral malalignment and thus be used to guide treatment. […] Recent literature has further supported Q angle (when measured utilizing a standardized protocol), crepitus, weakness of hip abductors and extensors, and weakness detected in functional testing as predictors of PFPS while finding inconsistent evidence behind lateral patellar tilt as a predictor of PFPS. The reliability of most physical examination tests alone remain low, but clustering physical examination findings may provide better sensitivities and specificities in diagnosing PFPS. Musculoskeletal US is rapidly gaining popularity, and decreased vastus medialis obliquus (VMO) volume, asymmetry in gluteus medius thickness, intra-articular effusions, and quadriceps and patellar tendon thicknesses have shown value in diagnosing those with PFPS.

  The generic term patellofemoral pain syndrome is frequently cited as a specific diagnosis, but it has never been specifically defined. In fact, it is not a diagnosis per se. To facilitate the arrival at a specific diagnosis, we categorize anterior knee pain into conditions pertaining to the patella proper, conditions pertaining to the peripatellar soft tissues and conditions altogether unrelated directly to the extensor mechanism. […] The term patellofemoral pain syndrome is not so much a diagnosis as an amalgam of disparate pathologies with similar presenting symptoms. […] No such specific criteria have ever been established for a patellofemoral pain syndrome. Thus, PFPS is not even a true syndrome. […] Patellofemoral pain syndrome is in fact an umbrella term encompassing disparate conditions, making it fruitless to offer generic treatment options for PFPS. It falls on the orthopedist to make as specific a diagnosis as possible.

  https://musculoskeletalkey.com/patellofemoral-syndrome/

  Patellofemoral syndrome (PFS) is one of the most common conditions in sports medicine and is the most common diagnosis of anterior knee pain. […] PFS is a clinical diagnosis with an absence of other pathologies. […] In sports medicine clinics, 25% of patients complaining of knee pain are diagnosed with this syndrome, and it affects women twice as often as men. […] The literature has focused on identification of risk factors leading to altered biomechanics to produce poor patellar tracking in the femoral trochlear groove and thus stress at the patellofemoral joint. […] The examination focuses on identification of risk factors that contribute to malalignment and rules out other pathologic processes associated with anterior knee pain. […] Each of these factors has either a direct or an indirect influence on the tracking of the patella with the femur. […] It is imperative to assess each of these components in the lower extremity kinetic chain to prescribe a tailored physical therapy program for each individual.

[…] PFS is considered a diagnosis of exclusion once intraarticular or peripatellar pathologies are ruled out. […] The diagnosis of patellofemoral syndrome is heavily reliant on a detailed and accurate history and physical examination. […] PFS is considered a diagnosis of exclusion; therefore, one must rule out other conditions that it may mimic. […] The diagnosis of patellofemoral pain syndrome is typically a clinical one. […] If the patient fails to respond to therapy, imaging is used to rule out other causes of similar pain, such as bipartite patella, osteoarthritis, loose bodies, and occult fracture.

  Patellofemoral pain syndrome (PFPS) is the most common cause of knee pain in the outpatient setting. […] The diagnosis of PFPS is made clinically, and although management can be challenging, a well-designed, nonoperative treatment program usually allows patients to return to recreational and competitive activities. […] For most patients, a careful history and physical examination are sufficient to make the diagnosis of PFPS. […] The differential diagnosis of PFPS is summarized in Table 2. […] Patients with PFPS typically describe pain behind, underneath, or around the patella. […] Common symptoms include stiffness or pain, or both, on prolonged sitting with the knees flexed (sometimes called the theater sign), and pain with activities that load the patellofemoral joint, such as climbing or descending stairs, squatting, or running.

  In this section, you will find detailed information about the diagnostic criteria for patellofemoral pain. […] According to the recommendations of a consensus statement from the 4th International Patellofemoral Pain Research Retreat published in 2016 and of the first clinical guideline on patellofemoral pain recently published in 2019, the diagnosis of patellofemoral pain is essentially based on the clinical presentation of patients, associated with the exclusion of other conditions that may cause knee pain. […] The main criteria for diagnosis of patellofemoral pain can be divided into: essential criteria, additional criteria, clinical tests and differential diagnosis. […] Essential criteria: Presence of pain around or behind the patella. Symptoms reproduction during activities that load the patellofemoral joint during weight bearing on a flexed knee (e.g., squatting, stair ambulation, jogging/running, hopping/jumping).

  Patellofemoral pain syndrome (PFPS) is characterized by a dull, aching pain located in the anterior retropatellar and/or peripatellar region of the knee. The diagnosis of PFPS is based on the presence of retropatellar or peripatellar pain, reproduction of pain with certain activities, and the exclusion of other conditions that may cause anterior knee pain. […] The diagnosis of patellofemoral pain syndrome (PFP), often characterized by insidious onset of poorly defined pain in the anterior retropatellar and/or peripatellar region of the knee, involves several steps. […] Clinicians should use reproduction of retropatellar or peripatellar pain during squatting as a diagnostic test for PFP. Additionally, the performance of other functional activities that load the patellofemoral joint (PFJ) in a flexed position, such as stair climbing or descent, can also be used as diagnostic tests for PFP.

  Pain while performing double leg squats has been shown to be the most sensitive physical exam finding for PFS and should always be used as functional diagnostic test during evaluation. […] Musculoskeletal ultrasound may be useful to evaluate for associated findings in PFS. […] Radiographic imaging is not usually performed for initial diagnosis of PFS unless there is a history of trauma or dislocation. […] The literature supports an exercise program specifically focusing on the hip and knee as the mainstay of treatment for PFS.

• #87 Patellofemoral Syndrome Workup: Laboratory Studies, Imaging Studies, Other Tests

  https://emedicine.medscape.com/article/308471-workup

  Laboratory studies are not indicated for the diagnosis of PFS. Serology, joint aspiration, and related tests may be useful when alternative diagnoses are suspected. However, such investigations are not likely to provide useful information in this syndrome, as it is not a disease entity but rather a group of symptoms occurring sometimes in association with multiple factors (intrinsic and extrinsic). […] PFS is a clinical diagnosis and usually does not require imaging to diagnose and treat. Nonetheless, imaging studies may be considered for unusual presentations and for patients who are refractory to conservative management. […] Plain film radiographs can be used to assess the patella’s position; the anterior-posterior (AP), lateral, and sunrise views can be particularly helpful. However, plain radiography is not necessary in the diagnosis of PFS, although it may be beneficial to rule out other etiologies of anterior knee pain or if conservative measures have been unsuccessful.
