Abstract
Anterior knee pain is a common problem that can be difficult to treat. One potential cause of these symptoms is supratrochlear rim, which has been linked to isolated patellar chondromalacia in patients with patella alta and without any history of patellar dislocation or subluxation. In cases where the rim does not exceed 3 mm, the rim resection technique was previously described. This technical note outlines rimplasty, an arthroscopic technique addressing the biomechanical etiology of patellar chondromalacia by modifying patellofemoral joint kinematics and reconstructing patellar cartilage. The described technique specifically targets cases in which the supratrochlear rim exceeds 3 mm in height on imaging.
