Brief summary

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.
