  • Gait analysis [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Motion analysis is performed prior to surgery and after 6 and 12 months follow-up. Patients serve as their own control.
  • DXA [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    Dual Energy X-ray Absorptiometry (DXA) is used to asses bone mineral density (BMD) around the implant.

Rehabilitation After Total Knee Arthroplasty (TKA) - PFC Rotating Versus Fixed Bearing
Rehabilitation After Total Knee Arthroplasty - Rotating Platform Versus Fixed Bearing Polyethylene

The purpose of this study is to determine whether patient rehabilitation is equal for patients operated with two different knee implant designs.

The patients are randomized to treatment with either a simple hinge design implant (fixed bearing) or an implant with a mobile bearing polyethylene. This design difference might in principle enable the patients in the latter group to rehabilitate towards a more normal gait pattern.
