Selective Epiphysiodesis of the Anterior Distal Femoral Physis Alters Trochlear Morphology in a Rabbit Model

The authors investigate how selective closure of different regions of the anterior distal femoral physis affects trochlear morphology in a rabbit model, aiming to understand its role in trochlear dysplasia and patellofemoral instability. Their findings demonstrate that targeted epiphysiodesis alters trochlear shape in a region-specific manner, suggesting that growth modulation strategies could be beneficial in managing early dysplastic changes in skeletally immature patients. This research emphasizes the importance of the anterior distal femoral physis in trochlear development and informs potential surgical interventions.
