• #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. […] It can tear after a hard twist or rotation of your knee. […] As you get older, the cartilage in your knees wears down and gets weaker. 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.

  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. In some cases, a piece of the shredded cartilage breaks loose and catches in the knee joint, causing it to lock up. […] 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 Meniscus Tear Causes

  https://mendmyknee.com/meniscus-injuries/meniscus-injury-causes.php

  The 2 most common causes of meniscus injuries are acute trauma to the knee and degeneration of the knee joint tissue. […] Forceful blows to the knee occur most frequently during activities such as rugby, football, baseball, soccer, basketball or racquet sports when you twist your knee, or slow down too quickly. […] A meniscus injury can occur during a hit if the knee is forcefully rotated while the foot is firmly planted and bearing weight. […] Over time, the tissue weakens and becomes less flexible, more brittle and develops small cracks in it. […] If osteoarthritis sets in, destructive chemical substances are released in the joint cavity which further breakdown the collagen fibers. […] As the menisci degenerate they become more susceptible to tears which can lead to a meniscus tearing without any associated injury. […] A discoid meniscus is at greater risk of tearing than a regularly shaped meniscus.

  Knee injuries are a problem for many people. The most common knee injury is the torn meniscus. Though a torn meniscus can happen to anyone, this injury occurs most often to athletes. […] A torn meniscus often happens suddenly during sports or other activities that cause a person to twist, rotate, bend, or lift very heavy objects. […] Sports injuries are the most common cause. Sometimes direct contact such as a football tackle causes a torn meniscus. […] Individuals with an increased risk include athletes, especially those that play contact sports, and dancers. […] Additionally, older adults naturally have an increased risk of knee injuries including a torn meniscus due to age-related knee changes and degeneration. […] Anyone with a previous knee injury may also be at higher risk for a meniscus tear that happens simultaneously due to the trauma that caused the other injury.

  A meniscus tear is one of the most common knee injuries. Any activity that causes you to twist or rotate your knee forcefully, especially when putting your full weight on it, can lead to a torn meniscus. […] Meniscus tears usually occur due to acute trauma or from degeneration of the tissue. Acute traumatic tears typically result from a forceful twist or sudden stop that can cause the end of the femur to grind into the top of the tibia, pinching and potentially tearing the cartilage of the meniscus. […] In older adults, the cartilage in the knee becomes weaker and less resilient, and a meniscus tear can occur with little or no trauma. This is considered a degenerative meniscus tear, occurring gradually over time. […] Increasing body weight can also put added stress on the meniscus. Routine daily activities like walking or climbing stairs can increase the potential for wear, degeneration and tearing of the meniscus.

  Meniscus injuries are common, affecting an estimated 6 in 1,000 Australians during their lifetime. Males between 20 and 29 are the most likely to suffer a meniscus tear, and (or possibly because) most meniscus injuries result from sport or sudden impact. […] A high proportion of meniscus injuries result from direct impact or over-rotation of the knee, or both. It might be a soccer tackle at the wrong angle, colliding with another person at high speed, landing awkwardly from a high step, coming down wrong when guarding in Netball the list is almost endless. […] Most meniscus injuries occur during sport. In Australia, soccer leads the field in meniscus injuries accounting for 32% of hospitalisations. Netball and AFL follow behind, accounting for 17% each.

  https://www.exakthealth.com/en-US/blog/an-overview-of-meniscus-tears-symptoms-causes-and-treatment-options

  Meniscus tears can be caused by trauma (acute tears) or wear and tear (degenerative tears). […] They usually happen with twisting or pivoting on a fixed foot, knocks to the knee, or when the knee is overstretched. […] Contact sports like soccer and rugby increase your risk, while running is considered a low risk for acute tears. An injury to any of the ligaments in the knee may also increase your risk. […] Research shows that meniscus tears in people over 30 usually occur due to wear and tear. As you age, normal degenerative changes happen in your connective tissue, bones, and muscles. They become a bit softer and less pliable over time and can’t take the same amount of force (load) as they used to. […] The highest risk factors for degenerative meniscus tears are: Increased age (60 years), Male gender (up to 3 times more in men than women), Work-related kneeling or squatting (1 hour a day), Repetitive stair climbing (30 flights a day), Carrying heavy weights or being overweight (BMI 25).

• #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).

  Tears or ruptures are the most common injury to the menisci. A tearing of the inner or outer meniscus is fundamentally caused by the same thing. For anatomical reasons, the inner meniscus is more often affected than the outer meniscus. […] The menisci can be put under high strain if you have an accident for example, if the knee is bent and loaded, and an uncontrolled rotating movement suddenly occurs. The pressure and simultaneous rotation lead to a shearing movement. This can lead cause the meniscus to tear. […] Frequent and severe bending owing to activities involving kneeling, for example, can lead to very small injuries that no longer heal (so-called micro traumas). After months or years, small injuries like these can expand into a large tear. […] As with all tissues in the human body, the meniscus is also subject to natural wear and tear. The elasticity of the fibrous cartilage decreases and the connective tissue of the menisci loses firmness, becomes adipose or brittle. In these cases, one simple deep knee bend or a rotation of the joint, when getting out of the car for example, can cause a meniscus tear. […] Increasing age can lead to tearing in the menisci owing to natural wear and tear.

  https://emedicine.medscape.com/article/308054-clinical

  Most commonly, meniscal injuries are due to a traumatic event (especially in athletes) or degenerative changes (in older individuals). Meniscal tears are caused by twisting motions with the knee in a flexed position (eg, pivoting in basketball). Chronic or repetitive stress also may cause degenerative tears of the menisci. […] A Danish study investigated whether an association exists between meniscal injuries and occupations that require kneeling. […] The incidence of degenerative tears of the medial meniscus was significantly higher in floor layers than in graphic designers, the odds ratio (OR) being 2.28. Medial tears in both knees also occurred more frequently in floor layers (OR 3.46). […] A study by Ward et al indicated that in persons with medial meniscal degeneration, the chances of sustaining an incident destabilizing medial meniscal tear within 4 years is three-fold higher than in individuals without such degeneration. Additionally, in persons with medial or lateral meniscal degeneration, the likelihood of developing incident accelerated knee osteoarthritis within 4 years was reported to be five-fold higher than in individuals with degeneration in neither meniscus.

• #1 Meniscus tear – Wikipedia

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

  A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. […] Menisci can be torn during innocuous activities such as walking or squatting. They can also be torn by traumatic force encountered in sports or other forms of physical exertion. […] The two most common causes of a meniscal tear are traumatic injury (often seen in athletes) and degenerative processes, which are the most common tear seen in all ages of patients. […] A meniscus can tear due to an internally or externally rotated knee in a flexed position, with the foot in a flexed position. […] Degenerative tears are most common in people from age 40 upward but can be found at any age, especially with obesity. […] The meniscus is made of cartilage, a viscoelastic material, which makes it more susceptible to rate of loading injuries.

  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. […] 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. This knee injury can also occur with deep squatting or kneeling, especially when lifting a heavyweight. Meniscus tear injuries often occur during athletic activities, especially in contact sports like football and hockey. […] The risk of developing a torn meniscus increases with age because cartilage begins to gradually wear out, losing its blood supply and its resilience. Increasing body weight also puts more stress on the meniscus. Routine daily activities like walking and climbing stairs increase the potential for wear, degeneration, and tearing.

  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.

  https://meniscustears.com/horizontal-meniscus-tear/

  A horizontal meniscus tear is a type of injury to the meniscus where the tear runs parallel to the surface of the meniscus rather than perpendicular to it. […] It may originate from a blister that forms within the internal portions of the meniscus and eventually splits through one of the meniscal surfaces dividing your meniscus into a bottom and top half (like an open fish mouth lower and upper jaw). […] If you choose to live with a horizontal meniscus tear or have it partially removed, cleaned up or trimmed, you are at a significant risk of developing knee arthritis a chronic knee problem that is often so painful that it requires total knee replacement surgery. […] Because a meniscus that has a horizontal tear results in increased pressures at focal regions of the femoral and tibial knee articular surfaces. This causes progressive degeneration of the articular cartilage.

  Meniscus tears can result from trauma and from the aging process. […] The incidence of meniscus injuries is on the rise due to increased sports participation by youth. […] Meniscus tears are increasingly common with age and are often discovered without knee trauma. […] Moreover, knee trauma in younger people is often not reported and some individuals may have a predisposition to atraumatic meniscus damage which reflects a propensity for developing OA. […] Studies show that these tears are common in the elderly especially in people who have symptoms of knee arthritis. […] Research is focused on why and the studies suggest that a torn meniscus increases the risk of knee OA. […] A 2013 study reported that knees with meniscus tears are at greater risk for developing OA later in life. […] Knees with known meniscal injury have accelerated cartilage wear, leading to early onset of osteoarthritis. […] Studies report that meniscus tears can lead to osteoarthritis of the knee, and conversely, OA of the knee can cause degenerative meniscus tears.

  https://alexanderorthopaedics.com/torn-meniscus/

  One of the most common knee injuries is a meniscus tear, which typically occurs from twisting or over-rotating the knee. […] Either meniscus can get trapped or pinched if the knee is twisted, bent, or straightened unexpectedly or aggressively. A severe pinch can lead to a tear in the cartilage itself. Kneeling, squatting, lifting something heavy, or other forms of hyperflexion and hyperextension can also lead to a torn meniscus. […] Risk factors for a torn meniscus include: Sports: Athletes participating in contact sports like football, or sports that involve pivoting, like basketball or tennis, are at a greater risk. Age: Older adults may tear a meniscus with little or no trauma, due to degenerative changes in the knee. Sex: According to a study published in the Journal of Orthopaedic & Sports Physical Therapy, male bodies are at a significantly greater risk for meniscal tears than female bodies. Occupation: The same study found that people are at a greater risk for degenerative meniscus tears if they are required to kneel or squat for more than one hour per day. Prolonged sitting, standing, walking or driving were also found to increase risk. Weight: Obesity usually increases pressure on the knees, which can increase the risk of tears. Smoking: Smokers tend to lose collagen in their cartilage at a greater rate than non-smokers, reducing the elasticity of their joints and making the meniscus more susceptible to tearing.

Although it most commonly affects older people, meniscus tears are the most common injury in the world of sport. […] A meniscus tear is an injury to the cartilage discs of the knee. This tear can be caused by trauma (accident, blow or sudden twist, etc.), or by wear and tear of the cartilage, which is associated with older people. […] A meniscus tear is usually caused by a sudden twist of the knee during sports. Although this injury can occur at any age and for a variety of reasons, sports such as football, basketball or tennis increase the risk of it happening. […] The causes of meniscus tears vary depending on the age and state of health of the affected person: This type of tear is related to age and the micro-traumas that arise over the years. In addition, over time, the meniscus loses moisture and dries out, making tears more likely to occur. Traumatic. A sharp twist or movement of the knee, such as pivoting, braking or turning aggressively and suddenly, can cause the meniscus to tear. On the other hand, simple acts such as kneeling, squatting or lifting can also cause this type of traumatic injury. Mechanical. This occurs when the joint does not function properly. The knee joint may present some deformity or malfunction such as excessive rotation, hyperextension or adopt a bad angle, which can cause an injury or meniscus tear.

Males between 20 and 29 are the most likely to suffer a meniscus tear, and (or possibly because) most meniscus injuries result from sport or sudden impact. […] A high proportion of meniscus injuries result from direct impact or over-rotation of the knee, or both. It might be a soccer tackle at the wrong angle, colliding with another person at high speed, landing awkwardly from a high step, coming down wrong when guarding in Netball the list is almost endless. […] Most meniscus injuries occur during sport. In Australia, soccer leads the field in meniscus injuries accounting for 32% of hospitalisations. Netball and AFL follow behind, accounting for 17% each. […] Menisci can tear from a combination of sudden impact and over-rotation, for example: Tackle at the wrong angle, Planting your feet wrong, Squatting or running on an uneven surface, Colliding with another players leg.

  A tear in the meniscus causes pain and locking. Injuries to the meniscus are common, particularly among athletes. […] The meniscus tears due to an acute injury (traumatic meniscal tear) or from being worn down over time (degenerative meniscal tear). Traumatic tears usually result from a forceful twisting of the knee. Degenerative tears usually occur in older people, as years of use can lead the meniscus to deteriorate. […] A traumatic tear of the meniscus usually occurs when a competitive athlete or other highly active person quickly turns their body, pivoting on the knee while their foot is still planted on the ground. […] Degenerative or atraumatic tears, usually seen in older people, are caused by biological degeneration and breakdown of the meniscal structure. […] Untreated tears can progress and become worse over time. Progressive meniscus loss can increase the risk that a person will develop degenerative knee arthritis.

  Tears or ruptures are the most common injury to the menisci. A tearing of the inner or outer meniscus is fundamentally caused by the same thing. For anatomical reasons, the inner meniscus is more often affected than the outer meniscus. […] The menisci can be put under high strain if you have an accident for example, if the knee is bent and loaded, and an uncontrolled rotating movement suddenly occurs. The pressure and simultaneous rotation lead to a shearing movement. This can lead cause the meniscus to tear. […] Frequent and severe bending owing to activities involving kneeling, for example, can lead to very small injuries that no longer heal (so-called micro traumas). After months or years, small injuries like these can expand into a large tear. […] As with all tissues in the human body, the meniscus is also subject to natural wear and tear. The elasticity of the fibrous cartilage decreases and the connective tissue of the menisci loses firmness, becomes adipose or brittle. In these cases, one simple deep knee bend or a rotation of the joint, when getting out of the car for example, can cause a meniscus tear. […] Increasing age can lead to tearing in the menisci owing to natural wear and tear.

  The meniscus weakens with age. Tears are more common in people over the age of 30. Movements like squatting or stepping can lead to injury in someone with weak menisci. […] If you have osteoarthritis, youre at higher risk of injuring your knee or tearing your meniscus. Osteoarthritis is a common joint disorder involving pain and stiffness in your joints caused by aging and wear and tear. […] When an older person experiences a meniscus tear, its more likely to be related to degeneration. This is when the cartilage in the knee becomes weaker and thinner. As a result, its more prone to tear.

  https://alexanderorthopaedics.com/torn-meniscus/

  One of the most common knee injuries is a meniscus tear, which typically occurs from twisting or over-rotating the knee. […] Either meniscus can get trapped or pinched if the knee is twisted, bent, or straightened unexpectedly or aggressively. A severe pinch can lead to a tear in the cartilage itself. Kneeling, squatting, lifting something heavy, or other forms of hyperflexion and hyperextension can also lead to a torn meniscus. […] Risk factors for a torn meniscus include: Sports: Athletes participating in contact sports like football, or sports that involve pivoting, like basketball or tennis, are at a greater risk. Age: Older adults may tear a meniscus with little or no trauma, due to degenerative changes in the knee. Sex: According to a study published in the Journal of Orthopaedic & Sports Physical Therapy, male bodies are at a significantly greater risk for meniscal tears than female bodies. Occupation: The same study found that people are at a greater risk for degenerative meniscus tears if they are required to kneel or squat for more than one hour per day. Prolonged sitting, standing, walking or driving were also found to increase risk. Weight: Obesity usually increases pressure on the knees, which can increase the risk of tears. Smoking: Smokers tend to lose collagen in their cartilage at a greater rate than non-smokers, reducing the elasticity of their joints and making the meniscus more susceptible to tearing.

• #2 Meniscal Injury Clinical Presentation: History, Physical, Causes

  https://emedicine.medscape.com/article/308054-clinical

  Most commonly, meniscal injuries are due to a traumatic event (especially in athletes) or degenerative changes (in older individuals). Meniscal tears are caused by twisting motions with the knee in a flexed position (eg, pivoting in basketball). Chronic or repetitive stress also may cause degenerative tears of the menisci. […] A Danish study investigated whether an association exists between meniscal injuries and occupations that require kneeling. […] The incidence of degenerative tears of the medial meniscus was significantly higher in floor layers than in graphic designers, the odds ratio (OR) being 2.28. Medial tears in both knees also occurred more frequently in floor layers (OR 3.46). […] A study by Ward et al indicated that in persons with medial meniscal degeneration, the chances of sustaining an incident destabilizing medial meniscal tear within 4 years is three-fold higher than in individuals without such degeneration. Additionally, in persons with medial or lateral meniscal degeneration, the likelihood of developing incident accelerated knee osteoarthritis within 4 years was reported to be five-fold higher than in individuals with degeneration in neither meniscus.

  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.

• #2 Meniscus tear – Wikipedia

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

  A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. […] Menisci can be torn during innocuous activities such as walking or squatting. They can also be torn by traumatic force encountered in sports or other forms of physical exertion. […] The two most common causes of a meniscal tear are traumatic injury (often seen in athletes) and degenerative processes, which are the most common tear seen in all ages of patients. […] A meniscus can tear due to an internally or externally rotated knee in a flexed position, with the foot in a flexed position. […] Degenerative tears are most common in people from age 40 upward but can be found at any age, especially with obesity. […] The meniscus is made of cartilage, a viscoelastic material, which makes it more susceptible to rate of loading injuries.

• #2 Meniscus Tears: Everything You Need to Know

  https://centenoschultz.com/condition/meniscus-tears/

  Meniscal tears occur when the knee joint has a large rotational or shearing force. This can happen when these forces occur while the knee is in motion, such as kneeling, squatting, or weightlifting. […] Any activity or sport with rapid acceleration and deceleration, a sudden change in direction, or jumping also increases the forces on the knee, which can cause meniscal tears. In someone with degenerative joint changes from arthritis or previous injuries, the menisci are more susceptible to tears. […] As people age, the knee cartilage loses water and becomes stiffer, leading to a degeneration of the menisci. The degenerative changes make the menisci more susceptible to tears and shearing. Horizontal tears are common in men over 40 due to the degeneration of the fibers that run parallel to the tibial plateau.

  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.

  Meniscus tears may develop suddenly due to an injury, or come on gradually over time due to wear and tear. […] A meniscus injury commonly occurs in sport where the foot is fixed and the knee twisted. […] A meniscus injury usually happens during sporting activities e.g. football, rugby and skiing. […] Meniscus tears typically occur when the foot is fixed, e.g. studs in the ground, and the knee is slightly bent and then twisted by a sudden turn initiated either by you or by a force to the outside of the knee. […] Wear and tear at the knee joint associated with aging can also cause a meniscus injury. […] Cartilage tends to become more brittle with age and everyday use of the knee can result in meniscus tears. […] Meniscal tears are also a common feature of knee arthritis. […] Medial meniscus tears are more common than lateral meniscus tears and often the medial collateral ligament (MCL) is injured at the same time.

• #2 Horizontal Meniscus Tear: Causes, Treatment Options, and Recovery

  https://meniscustears.com/horizontal-meniscus-tear/

  A horizontal meniscus tear is a type of injury to the meniscus where the tear runs parallel to the surface of the meniscus rather than perpendicular to it. […] It may originate from a blister that forms within the internal portions of the meniscus and eventually splits through one of the meniscal surfaces dividing your meniscus into a bottom and top half (like an open fish mouth lower and upper jaw). […] If you choose to live with a horizontal meniscus tear or have it partially removed, cleaned up or trimmed, you are at a significant risk of developing knee arthritis a chronic knee problem that is often so painful that it requires total knee replacement surgery. […] Because a meniscus that has a horizontal tear results in increased pressures at focal regions of the femoral and tibial knee articular surfaces. This causes progressive degeneration of the articular cartilage.

• #2 Meniscus Tear Causes

  https://mendmyknee.com/meniscus-injuries/meniscus-injury-causes.php

  The 2 most common causes of meniscus injuries are acute trauma to the knee and degeneration of the knee joint tissue. […] Forceful blows to the knee occur most frequently during activities such as rugby, football, baseball, soccer, basketball or racquet sports when you twist your knee, or slow down too quickly. […] A meniscus injury can occur during a hit if the knee is forcefully rotated while the foot is firmly planted and bearing weight. […] Over time, the tissue weakens and becomes less flexible, more brittle and develops small cracks in it. […] If osteoarthritis sets in, destructive chemical substances are released in the joint cavity which further breakdown the collagen fibers. […] As the menisci degenerate they become more susceptible to tears which can lead to a meniscus tearing without any associated injury. […] A discoid meniscus is at greater risk of tearing than a regularly shaped meniscus.

  Meniscus tears can result from trauma and from the aging process. […] The incidence of meniscus injuries is on the rise due to increased sports participation by youth. […] Meniscus tears are increasingly common with age and are often discovered without knee trauma. […] Moreover, knee trauma in younger people is often not reported and some individuals may have a predisposition to atraumatic meniscus damage which reflects a propensity for developing OA. […] Studies show that these tears are common in the elderly especially in people who have symptoms of knee arthritis. […] Research is focused on why and the studies suggest that a torn meniscus increases the risk of knee OA. […] A 2013 study reported that knees with meniscus tears are at greater risk for developing OA later in life. […] Knees with known meniscal injury have accelerated cartilage wear, leading to early onset of osteoarthritis. […] Studies report that meniscus tears can lead to osteoarthritis of the knee, and conversely, OA of the knee can cause degenerative meniscus tears.
