NCT00764335

Brief Summary

The purpose of the present study was to determine whether unilaterally operated total hip arthroplasty (THA) patients were superior to bilaterally operated THA patients with respect to aerobic endurance capacity, muscle strength and gait patterns 3-5 years after surgery, and to what extent medial femoral head offset (FO) influenced hip abductor strength.
