Unilateral vs Bilateral Total Hip Arthroplasty
March 16, 2018 updated by: Norwegian University of Science and Technology
Unilateral vs Bilateral Total Hip Arthroplasty - the Influence of Medial Femoral Head Offset and Effects on Strength and Aerobic Endurance Capacity
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.
