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.
Flipped meniscus appearance: The displaced fragment creates an abnormal signal within the joint in sagittal view. Plain Radiographs (X-rays): While X-rays cannot visualize meniscal tears, they may rule out bony injuries. Occasionally, a joint effusion may be observed.
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]
Los Angeles Angels star Mike Trout will have surgery to repair a torn meniscus in his left knee, sidelining the three-time AL MVP indefinitely. ... Trout had an MRI after playing in the Angels' 6 ...
Considering these facts, doctors consider different treatments to different kinds of tears: [3] If the meniscus has to be removed (menisectomy) because of injury (either because it cannot heal or because the damage is too severe), the patient has an increased risk of developing osteoarthritis in the knee later in life.
MRI can also show associated bone bruises on the lateral side of the knee, which one study shows, happen in almost half of medial knee injuries. [ 19 ] Knee MRIs should be avoided for knee pain without mechanical symptoms or effusion, and upon non-successful results from a functional rehabilitation program.
Treatment of meniscal cysts consists of a combination of cyst decompression (intraarticular decompression versus open cystectomy) and arthroscopic repair of any meniscal abnormalities. Success rates are significantly higher when both the cyst and meniscal tear are treated compared to treating only one disease process.
The procedures are more commonly performed to treat meniscus injury and to perform anterior cruciate ligament reconstruction. [3] While knee arthroscopy is commonly used for partial meniscectomy (trimming a torn meniscus) on middle aged to older adults with knee pain, the claimed positive results seem to lack scientific evidence.
