Arthroscopy 10.1016/j.arthro.2018.05.028 Knee 28434 <p>A recent study suggests that aggressive correction of the tibial tuberosity-trochlear groove (TT-TG) distance by tibial tubercle osteotomy and medialization during patellar stabilization surgery can result in diminished outcomes. The mechanism may be overmedialization resulting in excessive medial patellofemoral and tibial-femoral pressure. Measurement of TT-TG may be inaccurate, and medialization of the tibial tubercle may not be required in cases of lateral patellar instability with TT-TG >20 mm (which is a current algorithm). My indication for tibial tubercle osteotomy, generally anteromedialization, is lateral patellofemoral chondrosis, and my goal is to create an intraoperative tubercle-sulcus angle of 0, which can be readily visualized with the knee at 90°. This is true regardless of the preoperative TT-TG measurement, and this intraoperative measurement mitigates against an excessive tubercle-sulcus angle of 0, which can be readily visualized with the knee at 90° and is true regardless of the preoperative TT-TG medialization.<p> Surgery public document-rn21351 editorial
