The commonest cause of patellofemoral instability is deficiency of the Medial Patellofemoral Ligament (MPFL) which normally acts as a check rein on the inner side of the knee cap. Reconstruction of this ligament is a very successful procedure in over 90% of patients, to stop recurrent episodes of subluxation or dislocation and prevent further degenerative damage to the joint.
The MPFL is reconstructed using arthroscopic (key hole) surgery and a hamstring tendon graft. The surgery is performed under a general anaesthetic and is done as a day case procedure.
A brace is not usually required but there may be 1-2 weeks of protected weight bearing on crutches depending on the type of surgery performed.
Mr. Smith is an advocate of using x-ray guided surgery for accurate femoral tunnel positioning during MPFL reconstruction and uses a technique popularized by world renowned surgeon Professor Andreas Weiler in Berlin.
