Three Dimensional Gait Analysis After Total Knee Arthroplasty - Comparison of Objective and Patient-reported Outcomes Between Rotational and Fixed Tibial Platforms.

We prospectively enrolled patients with knee osteoarthritis indicated for total knee arthroplasty and randomized for either mobile rotational tibial platform arthroplasty or fixed-stabilised tibial platform arthroplasty. We regularly performed 3D Gait Analysis (preoperatively and in several postoperative periods) to see if either of the implants results in better objective and patient-reported outcomes.
