Fig. 2From: Intraoperative patellar maltracking and postoperative radiographic patellar malalignment were more frequent in cases of complete medial collateral ligament release in cruciate-retaining total knee arthroplastyPostoperative patellar tilt was defined as the angle between the intercondylar line and a line drawn through the prosthesis-bone interface. This skyline axial-projection radiograph shows a patellar tilt of 1.3°, which corresponds to normal patellar trackingBack to article page
