Indications in the Treatment of Patellar Instability
The Journal of Knee Surgery, 2010Recent developments in patellar instability have focused on the passive restraints against mediolateral patellar motion. Viewed from this perspective, muscle alignment is considered secondary because, although muscle forces are important, their ability to cause or prevent patellar dislocation depends on passive stability or the lack thereof.

Patellar Instability in Juvenile Amputees
Journal of Pediatric Orthopaedics, 1987Forty-three ipsilateral knees in 41 juvenile amputees were studied for determination of the extent and severity of patellar instability. The amputation was performed for trauma in 13 patients and congenital anomalies in 28 patients. Eleven patients had instability, and three had patellofemoral pain.

Surgical Treatment for Patellar Instability
Orthopedic Clinics of North America, 1992The initial therapy for patellofemoral pain remains conservative. Once this treatment plan fails and examination has clearly identified the cause of the patellofemoral dysfunction, surgical treatment is considered. No single procedure corrects all patellofemoral problems, and the patient's age, the causative factor, the condition of the articular ...

Patellar Instability: Imaging Findings
Seminars in Musculoskeletal RadiologyAbstractPatellofemoral instability results from impaired engagement of the patella in the trochlear groove at the start of flexion and may lead to pain and lateral patellar dislocation. It occurs most frequently in adolescents and young adults during sporting activities.

Update on the Management of Patellar Instability
Current Sports Medicine Reports, 2012Patellar instability is a complex topic that must be treated at the individual level. The majority of first-time patellar dislocations occur in sport, and there is a high rate of recurrence and ongoing symptoms. Physical examination and imaging studies can aid in treatment decisions.

Patellar stabilization for episodic patellar instability
2012In the overwhelming majority of cases, patellar dislocation results in injury to the medial retinacular ligaments, including the medial patellofemoral ligament (MPFL), leading to increased lateral patellar mobility. The MPFL is the primary ligamentous restraint against lateral patellar displacement.
