Cartilage & Joint Surface Tears

Cartilage (meniscal) & Joint Surface Tears

Cartilage (meniscal) tears are amongst  the most commonly diagnosed problems within the knee. They can occur either as the result of a single injury to the knee, classically involving a twist, but can also occur following a number of minor incidents or general overuse and the incidence of these increase with use. Tear site and pattern are important and through rare, the classic bucket handle tear can be repairable and this is doen as soon as possible after injury. After 6 weeks repair becomes more difficult.
In about 25% of our patients there's no injury at all, just normal, regular day to day activity, yet a tear or tears will occur.

The joint surfaces are the principal contact areas of the joint and are made of a layer of tissue called articlar or hyaline cartilage which coats the lower end of the thigh bone, op of the leg bone and the underside of the kneecap.

It is the articular cartilage that degrades over time and is also at risk of damage in a similar fashionto the mensiscal cartilages. As time goes on, the risk of joint surface damage increases such that by the age of 40 and over, they are as common if not more meniscal tears.

Rarely, more localised and significant joint surface injuries can occur and these are termed osteochondral injuries. These can occur most frequently in the 15–20 year age group.
