Several biomechanical parameters of standing and walking in 50 patients with osteoarthrosis after total knee arthroplasty were evaluated. The patients were randomly divided in two equal groups: in the first group the surgery was performed with computer navigation system and in the second - with traditional instruments. After TKA with computer navigation centers of common body pressure and legs pressure during standing phase improved significantly better than in traditional group. Walking parameters like step length, ground contact time and rhythm coefficient improved in both groups of patients but without significant difference. Thereby more precise orientation of implant that achieved during computer assisted TKA leads to better functional performance at 6 and 12 month after surgery.
