Chronic Patellar Instability

Patients undergoing medial patellofemoral ligament reconstruction for patellar instability can expect a high rate of return to sport with or without concomitant osteotomy, according to published results.

Published results showed knees with and without patellar instability had highly variable patellar morphology, as well as minimal association between measurements of patellar morphology and trochlear dysplasia.

According to recently published results, tibial tubercle osteotomy with concomitant distalization resulted in positive radiographic, clinical and functional outcomes in the treatment of patients with patellar instability and patella alta.

Isolated lateral release is a low-risk procedure that shows good short- to middle-term outcomes as a first-line surgical management of patients with patellofemoral instability, according to published results.

Medial patellofemoral ligament reconstruction in adolescent patients with patella instability results in less instability and subsequent surgery compared with no reconstruction surgery, according to presented findings.

Patellar apprehension in knee flexion of greater than 60° could identify patients with patella alta, severe trochlear dysplasia and increased tibial tubercle-trochlear groove distance, according to recently presented study results.

Recent study results revealed that trochlear dysplasia types on an axial view based on Dejour classification are not representative of the entire trochlear geometry. Therefore, multiple axial planes should be used clinically to more accurately describe the entire shape of the trochlear.

KOLOA, Hawaii — At Orthopedics Today Hawaii, John D. Kelly IV, MD, spoke about preservation of the native anatomy in sports medicine cases. He said menisci need to be fixed in nearly every case, when possible, and that articular cartilage lesions progress in time.
