Within the joint, the knee has individual ‘shock absorbers’ called meniscus, or cartilage. The role of the menisci is to help distribute force through the knee joint; they also act to provide nutrition to the bone surface and lubricate the joint. The two menisci are situated on the inner and outer compartments of the knee are shaped like same discs. Called the medial meniscus and lateral meniscus, the medial is larger than the lateral due to the role is plays in providing ‘shock absorption’ or distributing impact forces through the joint. The lateral is slightly smaller but more crescent in shape. Each meniscus differs in shape and size as it is designed to mould perfectly around the knee surface it protects. This is called congruence.
Meniscal injuries or cartilage tears are seen frequently in the clinic. Menisci can be damaged during a fall or stumble typically involving a twist to the knee. Often injured during sport, menisci can be torn during an ACL injury such as a football or rugby tackle. The Meniscus gradually wear and fray over time with natural ageing, causing pain or discomfort to the knee and is perhaps why the reason you feel your knee ‘catching’?
