Adequate protection rather than knee flexion prevents popliteal vascular injury during high tibial osteotomy: analysis of three-dimensional knee models in relation to knee flexion and osteotomy techniques

ConclusionAlthough the PA moved posteriorly during knee flexion, the small (1.7  mm) increment thereof and inconsistent movements in subjects would not be of clinical relevance to PA safety during HTO.Level of evidenceDiagnostic study, Level II.
