Recurrent Patellar Dislocation

Recurrent patellar dislocation is habitual lateral dislocation of the patella due to patellofemoral instability (TT-TG distance, trochlear dysplasia, patella alta, VMO weakness, ligamentous laxity). Treatment: acute: closed reduction, immobilization, ice, NSAIDs; conservative: physical therapy (VMO/quadriceps strengthening), patellar brace/taping, activity modification; surgical: medial patellofemoral ligament (MPFL) reconstruction, tibial tubercle transfer (Fulkerson), trochleoplasty, lateral release; post-op rehab; follow-up orthopedics/sports medicine.

Common Symptoms

Lateral knee pain; giving-way; audible pop; swelling; apprehension

Causes and Pathogenesis

Patellofemoral malalignment/instability causes recurrent lateral patellar dislocation.

Treatment

Reduction; immobilization; PT/brace; MPFL reconstruction; follow-up

Preventive Measures

Quadriceps strengthening; brace; avoid high-impact twisting.
