Mebio Knee

The MEBIO Knee is a modular prosthetic system for axis-free total surface replacement. It is now by far the most frequently used form of knee joint replacement.

The system comprises a femur component (Co-Cr-Mo), a tibia component (Co-Cr-Mo with a UHMWPE polyethylene plateau and a UHMWPE patella component) for optional use. The components are all available in various sizes and strengths. Two pegs and a textured back anchor the femur component securely in the cement. The joint surface permits limited rotation around its axis and allows it to slide backwards in flexion. The tibia component has a central shaft and a textured back. The shaft base is ventrally widened. This gives better rotation stability after the implant. The patella is a dome-shaped component with a central anchoring peg.

The outstanding quality of this prosthesis system is confirmed by the data in the Swedish Knee Arthroplasty Register, which has existed since 1975 and which by 1997 held records on more than 50,000 primary knee endoprostheses. During a 9-year period, the Scan Knee, which is marketed in Germany as the MEBIO Knee, showed extremely low cumulative revision rates (in %). (Robertsson O, Knutson K, Lewold S, Lidgren L.
