Rationale for preoperative planning in the supine position based on variability in the joint line convergence angle before and after open-wedge high tibial osteotomy
Postoperative weightbearing alignment following OWHTO is better predicted by preoperative supine than weightbearing imaging. Furthermore, large preoperative weightbearing JLCA (> 4.9°) and severe varus HKAA (> 8.8°) are associated with decreased postoperative JLCA.
