Fig. 1From: Difference in the early postoperative change of the joint line convergence angle between opening wedge and closed wedge high tibial osteotomiesPerioperative change of the joint line convergence angle (JLCA) preoperatively (Pre-op), immediately under general anesthesia postoperatively (0 day), 2 days, and 1 month postoperatively in closed wedge high tibial osteotomy (CWHTO; a) and opening wedge high tibial osteotomy (OWHTO; b). Decrease of the JLCA by opening of the medial joint space and closing of the lateral joint space is shown at 0 day in CWHTO (a) and at 2 days in OWHTO (b), and it is maintained thereafterBack to article page
