Norwegian University of Science and Technology

Status: Completed

Conditions: Osteoarthritis, Hip

Treatments: Procedure: total hip arthroplasty one side; Procedure: total hip arthroplasty both sides

Details and patient eligibility

About

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.
