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.

Arthroscopic Treatment of Chronic Tibial Spine Malunion.

Reports of surgical resection and internal fixation for symptomatic tibial spine malunion are rare, and the reported techniques typically involve an open surgical approach. We present an all-arthroscopic technique of tibial spine malunion treatment, with selective arthroscopic bone resection below the tibial spine, preserving the anterior cruciate ligament attachment, followed by internal fixation of the tibial spine with a hybrid transtibial and suture-bridge construct using knotless anchors and tape sutures.
