Gait Analysis and Neuromuscular Function After Primary Total Hip Replacement
The Effect of Implant Design on Postoperative Mechanical Muscle Function Recovery and Gait in Hip Replacement Patients: A Randomized Clinical Trail

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.

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
Interventional
Phase 2
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Osteoarthritis
  • Procedure: Articular Surface Replacement (ASR)
    Articular surface replacement, DePuy, posterolateral approach used
  • Procedure: Standard Total Hip Arthroplasty (THA)
    Device: Biomet 28mm
  • Experimental: Resurfacing Total Hip Arthroplasty
    A hip replacement that leaves most of the underlying bone intact and mimics the natural biomechanical features of the hip joint. Articular surface replacement ASR, DePuy posterolateral approach used (RTHA)
    Intervention: Procedure: Articular Surface Replacement (ASR)
  • Active Comparator: Standard Total Hip Arthroplasty (THA)
    A standard 28 mm head uncemented THA
    Intervention: Procedure: Standard Total Hip Arthroplasty (THA)
