Gonarthrosis
Conditions
Brief summary
Evaluation of a new navigation system in computer-assisted total knee arthroplasty.
Detailed description
Single-blind, randomised, prospective comparative study in two parallel groups (conventional or computer-assisted arthroplasty). The patient will be evaluated during 3 visits: inclusion D0 (before arthroplasty), M3 (intermediate visit 3 months after arthroplasty) and M12 (final visit 12 months after arthroplasty).
