• #1 Torn Meniscus: Causes, Symptoms, Treatment & Prevention

  https://my.clevelandclinic.org/health/diseases/17219-torn-meniscus

  Meniscus tears are a very common knee injury, especially among athletes. Sudden, twisting movements like pivoting to catch a ball can tear the cartilage in your knee. People with arthritis in their knees are also more prone to meniscus tears. […] A torn meniscus is a tear in the tough cartilage inside your knee. […] This thinner cartilage can tear more easily. Arthritis (a breakdown of cartilage in the joints) can also lead to a meniscus tear. […] Acute meniscus tears occur during a sudden motion in which your knee twists while your foot stays planted on the ground. The tear frequently occurs while playing sports. People whose cartilage wears down (due to age or arthritis) can tear a meniscus from a motion as simple as stepping on an uneven surface. Sometimes, degeneration from arthritis causes a tear, even without a knee injury.

  https://www.webmd.com/pain-management/knee-pain/meniscus-tear-injury

  Meniscus tears often happen in contact sports like football and wrestling, as well as in non-contact sports requiring jumping or pivoting, such as volleyball and soccer. […] A tear can happen when you change direction suddenly while running, or twist your upper leg while your foot is still and your knee is bent. These tears often occur alongside other knee injuries, like an anterior cruciate ligament (ACL) injury. […] But the menisci also weaken with age, so as you grow older, you might get a tear just from making an awkward turn when you get out of a chair. More than 40% of people 70 or older have had a torn meniscus. […] Meniscus degenerative tear is a tear due to aging (rather than because of a specific injury) and is often linked to knee osteoarthritis. Most people with this condition have no symptoms. Those who do may have knee pain and feel the knee locking up.

• #1 Knee Meniscal Tears – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK431067/

  Isolated meniscal tears occur due to rotational or shearing forces placed across the tibiofemoral joint, especially when an increased axial load is placed through the menisci. Such scenarios include positions with increased degrees of closed kinetic chain flexion (kneeling, squatting), lifting/carrying heavyweights, and activities requiring rapid acceleration/deceleration, change of direction, and jumping. […] A traumatic impact to the knee can also result in either isolated meniscal tears or tears occurring concomitantly with bony lesions or damage to the primary stabilizing ligaments of the knee, such as the anterior cruciate ligament (ACL) and MCL. Relatively less force is required to create tears in those with degenerative changes of the menisci, typically seen in adults over the age of 40y/o, often with concomitant osteoarthritis (OA).

  https://share.upmc.com/2025/02/meniscus-tear/

  Meniscus tears are one of the most common types of knee injuries. They typically happen either from an acute knee injury or from natural degeneration as you age. […] Your meniscus can tear when the knee twists, bends, or rotates awkwardly. In younger people, this typically happens with an acute injury to the knee. In middle-aged to older people, it typically results from age-related tissue degeneration. […] Acute meniscus tears often happen during sports, either from contact or noncontact. Injuries occur when your knee twists unnaturally while you’re planting your foot. This puts a strain on the meniscus, causing it to tear. […] Degenerative meniscal tears occur because of the body’s natural degeneration as it ages. Tissue wears down over time and becomes more prone to injury. Because of that, it typically takes less trauma to cause a degenerative meniscal tear. […] Common risk factors for meniscus tears include: Age – You’re at a higher risk of degenerative meniscal tears as you get older. […] Osteoarthritis – People whose knee cartilage has worn down because of osteoarthritis are at risk of a meniscus tear.

• #1 Meniscus tear – Wikipedia

  https://en.wikipedia.org/wiki/Meniscus_tear

  The meniscus is made of cartilage, a viscoelastic material, which makes it more susceptible to rate of loading injuries. […] Recent studies have shown people who experience rapid rate of loading and/or repetitive loading to be the most susceptible to meniscus tears. […] Damage to the meniscus due to rotational forces directed to a flexed knee (as may occur with twisting sports) is the usual underlying mechanism of injury. […] A valgus force applied to a flexed knee with the foot planted and the femur rotated internally can result in a medial meniscus tear. A varus force applied to the flexed knee when the foot is planted and the femur rotated externally result in a tear of the lateral meniscus.

• #1 Meniscus Tear | Lehigh Valley Health Network

  https://www.lvhn.org/conditions/meniscus-tear

  Meniscal tears can occur in several locations. Sometimes, a tear happens along the periphery, or rim, of the meniscus, creating a kind of flap in the tissue. This is called a bucket-handle tear. The whole rim can be torn, or a tear can go across the center of the meniscus. Degenerative tears can happen anywhere in the meniscus. When that happens, the meniscus can be torn in several directions and look frayed.

• #1 Meniscus tear in children and teens (knee injuries) | Children’s Hospital of Philadelphia

  https://www.chop.edu/conditions-diseases/meniscus-tear-children-and-teens-knee-injuries

  Meniscus tears usually occur after a sudden forceful twisting of the knee, which causes the meniscus the semicircular, wedge-shaped collection of soft cartilage in the knee to stretch and tear. […] Because a meniscus tear is caused by a sudden, forceful twisting of the knee, athletes and active people (particularly those who participate in contact sports) are at an increased risk of meniscus tears, but anyone can injure a meniscus. […] A unique type of meniscus problem occasionally encountered in children is an abnormally shaped meniscus called a discoid meniscus. The disk shape of these menisci makes them more susceptible to tearing.

  The meniscus is a disc-like structure that acts as a cushion between the femur and tibia bones in the knee. Tears can occur in the meniscus with traumatic injuries or from regular wear and tear. The injuries usually involve a twisting mechanism, but again, many patients do not even remember a distinct injury. […] The blood flow to the meniscus is very poor. Blood is what brings nutrients, growth factors and cells to the meniscus and allow it to heal. Since the meniscus has a limited blood supply, certain parts of the meniscus are more likely to heal tears and other areas can never heal.

  A torn meniscus is damage from a tear in the cartilage that is positioned on top of the tibia to allow the femur to glide when the knee joint moves. […] The meniscus can be damaged because of a single event or it can gradually wear out because of age and overuse, causing degenerative tears. […] A forceful twist or sudden stop can cause the end of the femur to grind into the top of the tibia, pinching and potentially tearing the cartilage of the meniscus. […] The risk of developing a torn meniscus increases with age because cartilage begins to gradually wear out, losing its blood supply and its resilience. […] Because some of the fibers of the cartilage are interconnected with those of the ligaments that surround the knee, meniscus injuries may be associated with tears of the collateral and cruciate ligaments, depending upon the mechanism of injury. […] While the normal cartilage is „C” or crescent-shaped, there is a variant shape that is oval or discoid. This meniscus is thicker and more prone to injury and tearing.

  One of the most common knee problems is a torn meniscus. […] The menisci are two pieces of tough, rubbery C-shaped cartilage that absorb shock in the knee joint. […] There are different types of menisci tears, and they can have different causes. Some injuries are a result of a sudden event, and some tears occur because of weakened or degenerative cartilage. […] A torn meniscus can happen during regular daily activities, but they commonly happen during sports, during motions that involve squatting or twisting, or as a result of direct impact. […] If you don’t seek treatment for a meniscus tear, it’s possible for the injury to cause further knee problems down the line. […] An untreated torn meniscus can also lead to other long-term problems, including early development of osteoarthritis in the knee. […] Conservative treatments may not be effective for some meniscus injuries and it can have a lot to do with what kind of tear it is and where it has occurred. […] A tear on the inside of the meniscus, however, does not have this same blood flow to promote healing and may require surgery.

[…] In the long term, untreated meniscus tears increase the risk of developing osteoarthritis, a condition that causes joint pain and stiffness. […] Knee instability from an untreated torn meniscus can lead to permanent joint damage, increasing the risk for arthritis.

• #3 Torn Meniscus: Symptoms, Treatment, Surgery, Recovery Time

  https://www.medicinenet.com/torn_meniscus/article.htm

  A torn meniscus is damage from a tear in the cartilage that is positioned on top of the tibia to allow the femur to glide when the knee joint moves. […] The meniscus can be damaged because of a single event or it can gradually wear out because of age and overuse, causing degenerative tears. […] A forceful twist or sudden stop can cause the end of the femur to grind into the top of the tibia, pinching and potentially tearing the cartilage of the meniscus. […] The risk of developing a torn meniscus increases with age because cartilage begins to gradually wear out, losing its blood supply and its resilience. […] Because some of the fibers of the cartilage are interconnected with those of the ligaments that surround the knee, meniscus injuries may be associated with tears of the collateral and cruciate ligaments, depending upon the mechanism of injury. […] While the normal cartilage is „C” or crescent-shaped, there is a variant shape that is oval or discoid. This meniscus is thicker and more prone to injury and tearing.

  Most commonly, meniscal tears are caused by some sort of traumatic injury or sports injury. An unnatural over rotation of the leg can cause the cartilage of either of the menisci to tear either fully or partially. […] Impact on the side or front of the knee can lead to a tear in either the lateral or medial meniscus. […] Common causes of a meniscal tear in sports include: Impact on the side or front of the knee, causing the knee joint to move to the side, can result in a tear of either menisci and occasionally the anterior cruciate ligament (ACL), as well. […] Over rotation of the knee due to planting or cutting on the leg too aggressively can cause a tear in either of the menisci. […] Degenerative conditions like knee osteoarthritis can lead to tears in the knees menisci. […] As we age, the cartilage that the meniscus is made of becomes less resilient and rubbery, allowing for injury even when there is less dramatic activity or impact.

  A person can develop a meniscus tear for two reasons: Trauma: Traumatic meniscus tears are common in people who play sports that may involve knee twist movements, such as football, basketball, and soccer. […] Degenerative disease: Degenerative tears occur in older adults with a weakened meniscal structure. The American Academy of Orthopaedic Surgeons notes that worn tissue is more likely to tear. […] A 2017 review notes that orthopedic surgeons frequently encounter older adults with degenerative meniscus tears and OA. […] Aging causes the meniscus to weaken, making it more prone to damage. […] Most meniscus tears cannot heal on their own. Without treatment, the tear may worsen. The loss of a meniscus can also lead to wear-and-tear arthritis.

  Meniscus tears usually occur after a sudden forceful twisting of the knee, which causes the meniscus the semicircular, wedge-shaped collection of soft cartilage in the knee to stretch and tear. […] Because a meniscus tear is caused by a sudden, forceful twisting of the knee, athletes and active people (particularly those who participate in contact sports) are at an increased risk of meniscus tears, but anyone can injure a meniscus. […] A unique type of meniscus problem occasionally encountered in children is an abnormally shaped meniscus called a discoid meniscus. The disk shape of these menisci makes them more susceptible to tearing.

  Treatment for a meniscus tear include rest, ice, compression, and elevation (RICE) and the use of pain relief drugs. If a meniscus tear results from arthritis, a doctor will treat the underlying cause. In some cases, a person may need surgery. […] Meniscus tears may happen due to trauma or in older adults with knee arthritis. […] While meniscus tears commonly happen as a result of sports injuries, people with OA are also at higher risk. […] One 2019 study suggests meniscal injuries can cause cartilage wear and increase a persons chance of developing early onset OA. […] Additionally, an older 2009 study involving people at high risk of developing knee arthritis found that those with meniscal injuries who do not undergo surgery may be more prone to having radiographic knee arthritis.

• #3 Cartilage defects, chondropathy in the knee: diagnosis and therapy – Priv.-Doz. DDr. Christian Albrecht, Knee and cartilage specialist

  https://www.knieschmerzen-wien.at/cartilage-defects-en.html

  A joint is the movable connection of two or more bones. The joint surface is covered by smooth articular cartilage. […] Cartilage defects, called chondropathia or chondropathy in Latin, can occur acutely in the context of an accident or chronically due to overuse. […] Frequent causes of chronic cartilage damage in the knee are constant overloads, which occur, for example, due to an incorrect position of the leg axis (knock knees or bow legs), overweight, meniscus damage or instability in the knee joint. […] If left untreated, cartilage defects leads to arthrosis over time. […] Osteochondritis dissecans is a special form of cartilage defects in which the bone under the cartilage dies and the bone-cartilage piece can become detached. The reasons for the development of osteochondritis disssecans are not yet fully understood. Mechanical causes are suspected.

  A meniscus tear is a common type of damage to cartilage in the knee. The cartilage is found between the bones in the knee joint and protects them when you move. It usually gets damaged because of an injury. […] A meniscus tear usually happens when you twist your knee while playing sport. But it can also happen from more minor injuries such as twisting when standing up. […] A meniscus tear can get better on its own without treatment, but it can take a while to heal. […] If the damage is severe, you may need arthroscopy surgery to repair or remove the damaged cartilage.
