Medial Patellofemoral Ligament Repair/Reconstruction

Banff Sport Medicine

The Medial Patellofemoral Ligament (MPFL) is a ligament that prevents your patella (knee cap) from dislocating to the outside of your knee. This ligament is commonly injured when you dislocate your patella laterally. Approximately half of all people who dislocate their patella will have ongoing problems with instability. If you have ongoing instability, you may require surgery to repair, tighten (imbricate) or replace (reconstruct) the MPFL. If your anatomy or alignment increase the risk of you dislocating your patella, you may require other surgeries in addition to (but at the same time as) an MPFL surgery.
