Editorial Commentary: Stabilize the Patella to Achieve Functional Gain but Don't Neglect the Cartilage That May Cause Long-Term Pain! Trochlear Dysplasia Plays a Role in Both
? 2021 Arthroscopy Association of North AmericaWhile trochlear dysplasia is commonly discussed as a major risk factor for recurrent patellar instability, it also has a strong relationship with the development of patellofemoral cartilage lesions. Patellofemoral instability frequently occurs in teens and young adults, and the high prevalence of associated cartilage damage unfortunately sets patients up for the progression of degenerative changes of the patellofemoral joint at an early age. The judicious use of magnetic resonance imaging can help identify the presence of chondral lesions, allowing for urgent management of associated osteochondral fractures or open discussions and patient education about the possibility of performing a cartilage restoration procedure concurrently with patellar stabilization surgery. The location and presence of patellofemoral chondral lesions should be considered when contemplating the concurrent use of tibial tubercle osteotomy as part of the patellar stabilization procedure.
