A prospective randomized study where the patients are randomized too receive a monoblock tibial component with trabecular metal coating (TMT Zimmer NexGen®) or a modular tibial component (TMT Zimmer NexGen®). Both prostheses are available and approved by the FDA and CE. The only difference between the implants is that of the polyethylene insert (monoblock vs. modular).
The operations are performed at the Department of Planned Elective Surgery Z, Gentofte Hospital by two experienced TKA surgeons that will be included in the research group. During surgery a minimum of 4 Tantalum markers (0.8 mm) is inserted in the bone of the proximal tibia and 6 markers are inserted in the polyethylene insert.
