Knee cap dislocation

What is knee cap dislocation surgery?

Kneecap dislocation surgery is performed in the case of kneecaps which have suffered from a severe dislocation, and also to address further damage to cartilage, ligaments and tendons which surround the kneecap. This can often occur as a result of injuries sustained due to sporting activities, or sudden movement.

Typically, arthroscopic surgery, involving small incisions and the inserting of a small camera, is conducted initially to determine damage, followed by reconstructive surgery which can repair or remove damaged cartilage, and if necessary replace a relocated kneecap.


What can I expect from the procedure?

There are several different types of kneecap dislocation surgery, and the type performed will depend on the severity of the case.

Lateral release is a relatively simple procedure, which is used to address instability after the kneecap has come out of place. In this procedure, on the outside of the knee joint, the knee joint capsule is cut, centring the kneecap in an optimum position.

Medical imbrication tightens the tissue on the knee’s inner side and is usually achieved by the advancement of the quadricep muscle attachment.

MPFL repair is a modern procedure which is focused on the medial patellofemoral ligament (MPFL). In the case of first-time dislocations, this procedure can repair the torn ligament, or in the case of repeat dislocations, reconstruct it.

Bone realignment is a procedure which corrects abnormal anatomy which has led to the kneecap becoming dislocated and involves different types of surgery, including the Fulkerson procedure.


Why might I need kneecap dislocation surgery?

The cause of a kneecap dislocation often determines whether the treatment involves surgery – the dislocation could be due to a torn ligament, or in other cases, the bone anatomy or alignment might be the issue.

Kneecap dislocation surgery is typically decided on when non-surgical treatment, such as physical therapy, has failed to address the issue. Surgery is often the course of action taken if you’ve had several knee dislocations.

What is the recovery time?

Following surgery, in some cases, you will need to wear a brace on your knee to lock it into place. A Jones dressing allows your knee to heel, and physical therapy can begin immediately in order to build up strength and improve range of motion.

A full recovery is expected to take several months and will depend on the specific procedure undergone. Mr Mann will be able to advise on the best aftercare regime for your personal needs.
