A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci.When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae.
Each meniscus has an outer vascular zone (red-red zone), which has a good blood supply and healing potential as well as a central avascular zone (white-white zone), which has limited healing capability. [2] The medial meniscus is more prone to injury due to its firm attachment to the joint capsule and limited mobility.
A 2008 study in the New England Journal of Medicine which shows that about 60% of meniscus tears cause no pain and are found in asymptomatic subjects. [1] The three major treatments for a damaged meniscus are repair, removal, and transplantation. The surgery is often carried out arthroscopically. [citation needed]
Damage to the outer third of the meniscus has the best healing potential because of the blood supply, but the inner two thirds of the medial meniscus has a limited blood supply and thus limited healing ability. Large tears to the meniscus may require surgical repair or removal. In terms of a meniscus tear, the doctor can categorize the injury ...
Arthroscopic surgery, however, does not appear to result in benefits to adults when performed for knee pain in patients with osteoarthritis who have a meniscal tear. [18] [12] [19] This may be due to the fact that a torn meniscus may often not cause pain and symptoms, which may be caused by the osteoarthritis alone. [20]
In March 2023, Ball had a cartilage transplant procedure on the knee after a torn meniscus in January 2022. That surgery, in which damaged cartilage is repaired with cartilage cells from the ...
Minnesota Vikings quarterback J.J. McCarthy has a torn meniscus in his right knee that will require surgery, derailing the rookie's preseason progress and putting his status for the regular season ...
A tear in the meniscus may cause a pedunculated tag of the meniscus which may become jammed between the joint surfaces. To perform the test, the knee is held by one hand, which is placed along the joint line, and flexed to complete flexion while the foot is held by the sole (of the foot) with the other hand.
