Ligament Injury

Anterior Cruciate Ligament (ACL) Injury

This injury usually occurs as a result of a twisting injury to the flexed  knee whilst under load – as often occurs on the football field during a tackle. Commonly, other structures are also injured, including the medial collateral ligament (MCL) and meniscus (‘cartilage’). There is usually severe pain, with rapid swelling of the whole knee and an inability to carry on playing. There is often a feeling of instability of the joint, which may ‘give way’ (collapse) under load.

Immediate treatment includes rest, ice and painkillers. Physiotherapy will help the joint regain strength and movement, but despite this the knee may remain unstable. In such cases, surgery is often recommended.

Medial Collateral Ligament Injury

The MCL is injured usually following a blow to the knee during sport or a fall. Pain and swelling on the inner side of knee is accompanied by some difficulty moving the knee fully. If the ligament is only partially torn, a full recovery is likely within a few weeks with the help of a physiotherapist. Complete tears must be treated urgently to avoid the development of long-term problems of instability.

Posterior Cruciate Ligament and Postero Lateral Corner Injury

These complex structures at the back and outer side of the knee joint can be injured individually or together, leading to significant problems with knee function if not recognised early and treatment started immediately. Surgery is often required.
