What is it about?

Coronal alignment of the knee is defined by the hip-knee-ankle angle (HKA), the femoral mechanical angle (FMA), the tibial mechanical angle (TMA), and the joint line convergence angle (JLCA). To date, there is still a lack of knowledge about the variability of native coronal knee alignment. The purpose of this paper is to present a systematic review of the current literature about the variability of coronal knee alignment (HKA, FMA, TMA, and JLCA) in non-osteoarthritic knees.

Why is it important?

The problem is that coronal alignment is an important target in knee arthroplasty. However, there is still not sufficient data what a normal coronal alignment is in native or osteoarthritic knees. From the perspective of the ongoing discussion about personalised knee arthroplasty it is of utmost importantce to gain a better understanding of alignment needs.


This review gives an overview about current knowledge of coronal alignment in knee arthroplasty. It is not always what is believed for centuries, that stands the test of time. Find out the difference between myth and truth in coronal alignment.
