Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate whether subjects receiving a high-flexion knee prosthesis show a better knee function than patients receiving a standard knee prosthesis. Thigh-calf contact force measurements are used to quantify knee function. The investigators' hypothesis is that high-flexion knees show a better knee function.

Detailed Description

Study title:

Functional evaluation of a standard and a high-flexion knee prosthesis using thigh-calf contact force measurements.

Objective:

The objective of this study is to investigate whether subjects receiving a high flexion knee prosthesis (Sigma RP-F, J\&J, UK) show a better knee function than patients receiving a standard knee prosthesis (Sigma FB, J\&J, UK).

Study Design:

Prospective double blind randomized study.

Study population:

Subjects who will receive total knee arthroplasty (TKA) because of invalidating gonarthritis based on primary osteoarthritis or rheumatic disorders or trauma.

Intervention:

* 28 subjects will receive the standard Sigma FB knee prosthesis.
* 28 subjects will receive the high flexion Sigma RP-F knee prosthesis.
