A Study of Comparing Functional Outcomes after Kinematic and Mechanical Alignment in Total Knee Arthroplasty


About this study

The study aim is to conduct a clinical research investigation to compare two alignment techniques used in contemporary total knee arthroplasty by means of a prospective non-randomized clinical trial. The two alignment techniques are Kinematic Alignment (KA) and Mechanical Alignment (MA).
