Meniscal Surgery
A meniscus tear injury can occur to either one or both of the menisci found within the knee joint. Menisci are crescent-shaped rings, triangular in cross-section. They are made of collagen and rubbery in nature. It is believed that they have a shock absorbing function. Some experiments have suggested that injury to the meniscus may increase the risk of arthritis.
The mechanism of injury can involve twisting, pivoting, sudden stops and turns of the knee while playing sport. It could also be caused by movements such as kneeling, squatting or lifting something heavy. Even stumbling or mis-stepping can cause a tear. Sometimes tears can occur without obvious trauma because the meniscus is degenerate. Tears can also be present as part of the wider degenerative changes found with osteoarthritis.
