Identification of tibial tubercle ossicle during arthroscopic resection for recalcitrant Osgood-Schlatter disease in left knee using 2-portal technique. Viewing is performed through an anteromedial portal using a 70° arthroscope after arthroscopic shaver and radiofrequency electrode debridement, then looking inferiorly and lateral to the intact and protected patellar tendon (blue arrow). An anterolateral working portal is used to excise the ossicle (red arrow) with an arthroscopic burr (orange arrow) after skeletonization of the ossicle with a shaver and radiofrequency electrode directed away from the patellar tendon.
