Fig. 1From: Preserving coronal knee alignment of the knee (CPAK) in unicompartmental knee arthroplasty correlates with superior patient-reported outcomesRadiologic parameter measurements: A Preoperative MPTA, B preoperative LDFA, C postoperative MPTA, and D Postoperative LDFA. In C and D the joint lines were measured using a line extending from the distal end of the femoral component to the center of the lateral joint space.
