Meniscal tears can cause pain in the knee as well as mechanical symptoms including locking, catching, intermittent sharp pains, and sometimes even a sensation of giving way. The majority of meniscal tears are degenerative but sometimes a single injury can suddenly extend a developing tear, causing it to become symptomatic and painful. Unfortunately, because of the instability (movement) of the torn fragment of the meniscus and its limited blood supply, meniscal tears generally do not heal or regenerate themselves. The edges of these degenerative tears tend to be fragmented and frayed without clean edges. This factor, combined with a poor blood supply, indicates that most meniscal tears cannot be effectively repaired, or sewn back together. Most require arthroscopic partial menisectomy; a removal of the torn and damaged portion of the meniscus.
