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.

Inclusion Criteria:

• Patients at Silkeborg Regional Hospital, Orthopedic Dept. referred to total knee arthroplasty.

Exclusion Criteria:

• Neurologic disease with impact on gait.
• Orthopaedic disease ipsilateral hip joint.
• Patients outside the age limits.
• No informed consent signed.
• Patients suffering from dementia.
• Patients primarily included, but who perioperatively has their posterior cruciate ligament injured or sacrificed.
• Patients who later develop deep venous thrombosis or infection in the operated knee.
