MPFL Reconstruction
During a dislocation, the patella may “jump” out of its track and snap back, stretching or tearing the MPFL. This typically causes:
Sudden pain and swelling
Feeling of instability or the kneecap “slipping out”
Risk of future dislocations
Why Treatment is Important
If left untreated, the MPFL may heal stretched or weakened, causing chronic patellar instability. Repeated dislocations can damage cartilage under the kneecap, increasing the risk of patellofemoral arthritis.
MPFL Reconstruction Surgery
What Is It?
MPFL reconstruction is a surgical procedure to restore kneecap stability by replacing the damaged ligament with a graft (from the patient or donor).
Indications:
Recurrent patellar dislocations
Failure of conservative treatments such as bracing and physiotherapy
MPFL reconstruction is an effective modern solution. Before 2006, treatment was limited to immobilization and rehabilitation, often with limited success in preventing further instability.
Post-Surgery Recovery
Weight-bearing is allowed immediately, but the leg is supported in a brace for about six weeks to keep the knee straight
Continuous Passive Motion (CPM) machines may be used at home to prevent stiffness
Formal physiotherapy begins around six weeks post-op, once quadriceps strength improves
Optional tools may include electrical stimulation for muscle strengthening and compression/cold therapy to reduce swelling
Return to Sports
Most patients resume athletic activities within 4 to 7 months
Recovery time varies depending on individual healing, pre-existing joint conditions, and adherence to rehabilitation
A personalized recovery plan is provided based on surgical outcome and patient needs
