The medial patellofemoral ligament (MPFL) is a ligament that stabilises the knee. It makes up part of the soft tissue in the knee joint, attaching to the underside of the patella and the femur bone. Damage to the MPFL can occur when kneecap is dislocated or fractured, with the common causes being a sporting injury or fall. When this happens, the kneecap can become loose as it can no longer be held in the groove at the end of the thigh bone.

When MPFL repair
may be recommended

The MPFL is a key stabiliser that helps keep the kneecap tracking correctly. Repeated dislocation, persistent instability, or associated cartilage injury can indicate the need for surgical treatment.

Recurrent kneecap dislocation or subluxation episodes.
Painful instability affecting walking, sport, or confidence.
Imaging findings that suggest high risk of further patellar damage.

Depending on tissue quality and anatomy, treatment may involve repair, reconstruction, or a combined stabilisation strategy.

Frequently Asked Questions

What is the recovery time for MPFL surgery?

Most patients will be able to return home the same day of the surgery. However, you will experience difficulty bending the knee which is likely to be accompanied by swelling of the knee.

Can I have MPFL repair surgery on medication?

It depends on what the medication is. You will need to notify your surgeon if you are on warfin or clopidogrel, but it is worth asking their advice for other medications also. They will then advise accordingly ahead of the procedure.

What happens if I don’t have the MPFL operation?

If it’s your first kneecap dislocation, there is a chance that physiotherapy will prove to be an effective treatment option. However, if your patella has dislocated multiple times before, you will continue to experience joint pain and discomfort if left untreated. MPFL damage can also lead to complications with arthritis.
