What to expect from MPFL reconstruction for patellar dislocation

The medial patellofemoral ligament helps keep the kneecap aligned as the knee bends. Reconstruction uses a graft to recreate this stabilising restraint, sometimes alongside treatment of cartilage or bone alignment. Swelling, stiffness and discomfort around the kneecap are common early experiences. A brace and crutches may limit movement or weight-bearing while the graft settles.

Use the brace and crutches exactly as instructed, protect the wound and complete the prescribed exercises. Early physiotherapy focuses on swelling control, safe knee movement and quadriceps activation; later work adds strength, balance and movement control. Avoid kneeling, pivoting and impact until your surgeon or physiotherapist allows them. Return to sport follows demonstrated control rather than eagerness alone.

Contact the surgical team for increasing redness, drainage, fever, severe swelling, uncontrolled pain or new calf pain. Seek urgent care for a cold or pale foot, sudden marked weakness, chest pain or difficulty breathing. A new kneecap shift, fall or inability to bear weight should be assessed promptly.

Ask how far the brace may open, when weight-bearing and driving are allowed, which exercises protect the graft, and what strength and movement tests are needed before sport.
