Patellar Dislocation & Instability (Unstable Kneecap)

Patella Dislocation & Instability (Unstable Kneecap)


Treatment for patellar dislocation needs to be tailored to the exact cause of the dislocation, this may consist of both surgical and non-surgical options.

Immedate Treatment

If the patella remains dislocated, it needs to be put back in place by a doctor as soon as possible.

Nonsurgical Treatment

Mr Slattery will advise you regarding the use of braces, weight bearing, crutches and a specific physiotherapy program depending upon the cause of the patellar dislocation.

Because knee ligaments can be damaged by dislocation, the patella is often unstable after the injury. This can result in further dislocation, often requiring less force than the initial dislocation. Recurrences are also common if the dislocation was caused by an abnormality in the knee structure. Overall the recurrence rate is between 20-50%.

Surgical Treatment

If your knee has sustained injury to the cartilage or if the patella dislocates multiple times, surgery may be recommended to correct the problem. The cause of the instability will determine the type of surgery required. There is a wide variety of surgery available to treat patellar dislocation, which Mr Slattery is able to utilise to treat the exact cause of the dislocation.  Mr Slattery is skilled in minimally invasive techniques of ligament reconstruction, femur realignment and arthroscopic techniques to treat patellar instability which he will discuss with you during your consultation.
