Reference axes for optimal femoral rotational alignment in varus osteoarthritic Indian knees - A CT based study.

Background: Optimal rotational alignment of femoral component is important for longevity and success of total knee replacement. Whiteside line (WL), posterior condylar axis (PCA) and femoral transepicondylar axis are various intra-operative landmarks to guide femoral rotation. Each of these has its pros and cons.
