Arthroscopic Patellar Osteochondral Transplantation

The undersurface location of the patellar articular cartilage presents unique challenges to osteochondral defect treatment. Current osteochondral grafting techniques and instrumentation require arthrotomy and patellar eversion to access the defect with the necessary perpendicular trajectory. We describe an all-arthroscopic patellar osteochondral grafting technique, with transpatellar retrograde reaming for recipient socket creation and graft fixation, to treat focal patellar cartilage defects.
