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.
髌骨关节软骨的下表面位置给骨软骨缺损治疗带来了独特挑战。当前的骨软骨移植技术和器械需要切开关节并翻转髌骨，以必要的垂直轨迹进入缺损部位。我们描述了一种全关节镜下髌骨骨软骨移植技术，通过经髌骨逆行扩孔来创建受体骨槽并固定移植物，以治疗局限性髌骨软骨缺损。
