The rehabilitation process after surgical intervention for patellar instability warrants special consideration of the anatomy, biomechanics, and surgical procedure to facilitate the best outcomes for the patient. There is a paucity of evidence-based literature regarding post-operative rehabilitation protocols for the patellofemoral (PF) compartment. Recommendations for early rehabilitation (0–6 weeks) after lateral retinacular lengthening, medial PF ligament reconstruction, tibial tubercle osteotomy, and trochleoplastyare reviewed in this article. For each procedure, the following common post-operative rehabilitation focus points are reviewed: Weight-bearing status and brace use, joint range of motion, and strengthening.

Patellar instability is a complex problem that requires a thorough evaluation and work up. A critical part of this work up is appropriate imaging. This article reviews key imaging techniques and important imaging findings in patellar instability patients. This includes the evaluation of patella alta, trochlear dysplasia, lateral patellar tilt, extensor mechanism alignment, valgus alignment, rotational alignment, and soft tissue injury. Effective management for patellar instability relies on a comprehensive approach where any of these elements are evaluated when necessary.
