Acquired Distal Femoral Deformity After MPFL Reconstruction Don’t Do This Case Report

Abstract

Background: While reconstruction of the medial patellofemoral ligament (MPFL) is one of the most frequently performed surgical procedures in skeletally immature patients with patellar instability, there is an inherent risk to the distal femoral physis during femoral tunnel placement

Methods: This case report describes a distal femoral valgus deformity caused by partial lateral physeal growth arrest after MPFL reconstruction.  

Results: The acquired distal femoral valgus deformity was successfully treated with a distal femoral varus-producing osteotomy. 

Conclusion: This case highlights the importance of understanding the distal femoral anatomy and avoiding areas where the physis may be violated.
