Medial Patellofemoral Ligament (MPFL) Reconstruction

Medial Patellofemoral Ligament (MPFL) Reconstruction for kneecap instability 
What is the MPFL?

The Medial Patellofemoral Ligament (MPFL) is a key stabilizer of the kneecap (patella), preventing it from dislocating laterally (towards the outer side of the knee). It connects the inner side of the patella to the femur (thigh bone). Injuries to the MPFL often occur due to trauma or congenital factors, leading to recurrent patellar dislocations and instability.

Why Might I Need MPFL Reconstruction?

If you’ve experienced repeated dislocations of the kneecap, especially after non-surgical treatments like physiotherapy have failed, MPFL reconstruction may be recommended. This procedure aims to restore stability to the patella, reducing the risk of future dislocations and associated pain.

The Surgical Procedure

MPFL reconstruction involves creating a new ligament to replace the damaged one. This is typically done using a graft from your own hamstring tendon or a donor tendon. The new ligament is anchored to the femur and patella to restore normal tracking of the kneecap. The surgery is usually performed under general anesthesia and may be done as a day case or require an overnight stay.

Recovery and Rehabilitation

Post-operative care is crucial for a successful outcome:

  • Immobilisation: A knee brace may be used to keep the knee in a straight position initially.

  • Physiotherapy: You’ll begin a structured rehabilitation program focusing on restoring range of motion, strengthening the quadriceps, and improving balance.

  • Weight Bearing: Depending on your surgeon’s advice, you may start with partial weight-bearing and progress to full weight-bearing as tolerated.

  • Return to Activities: Most patients can return to low-impact activities within 3 months, with a gradual return to sports over 6 to 9 months, depending on individual progress.

Risks and Considerations

As with any surgical procedure, there are potential risks:

  • Infection

  • Blood clots

  • Knee stiffness or continued instability

  • Graft failure

Mr Davies will discuss these risks with you and take steps to minimise them.

Outcomes

MPFL reconstruction has a high success rate in restoring patellar stability and allowing patients to return to their desired activities. Adherence to the rehabilitation program and follow-up appointments is essential for optimal recovery.
