Supratrochlear Rim Resection: Autologous Matrix‐Induced Chondrogenesis–Based Arthroscopic Technique for Patients With Isolated Patellar Chondromalacia

Year: 2025

Type: article

Abstract: Isolated patellar chondromalacia in patients with patella alta and no history of patellar subluxations or dislocations is associated with a supratrochlear rim at the entrance to the femoral trochlea. This technical note outlines an arthroscopic technique called supratrochlear rim resection, which proposes a line of treatment that addresses not only symptoms (patellar cartilage defect) but also a suspected biomechanical reason (supratrochlear rim). The proposed technique combines resection of the supratrochlear rim with a modification of autologous matrix-induced chondrogenesis cartilage reconstruction on the femoral side at the location of the resected rim, as well as on the patellar defect.
