Summary

This study is conducted at Odense University Hospital(OUH) in collaboration with Institute of Clinical Biomechanics and Sport Science, University of Southern Denmark and Clinical Institute, University of Southern Denmark Aim: To evaluate the effect of implant design on postoperative total leg muscle function recovery and gait in hip replacement patients. Design: A prospective randomized controlled clinical trial where patients are randomized into (A) total hip arthroplasty surgery (THA) or (B) resurfacing total hip replacement surgery (RTHA). Pre-surgery assessment and follow-up will be conducted at 8, 26 and 52 wks post-surgery.

Detailed description

The project consist of three substudies: * Determination of test-retest reliability and agreement of specific mechanical muscle function variables for the patients of interest. * Evaluate the effect of implant design on postoperative mechanical muscle recovery * Evaluate the effect of implant design on postoperative gait

Conditions

• Osteoarthritis
