Gait Analysis and Clinical Outcomes of Anterior and Lateral Approach Total Hip Arthroplasty.
- Conditions
- Hip Osteoarthritis
- Interventions
- Procedure: total hip replacement using lateral approachProcedure: total hip replacement using anterior approachDevice: gait analysis at 6wks, 3 months and 18 months
- Registration Number
- NCT06538519
- Lead Sponsor
- Ain Shams University
- Brief Summary
The goal of this Prospective Randomized Study is to confirm presence or absence of differences in gait mechanics in direct anterior and lateral approaches for total hip arthroplasty. and to compare the clinical outcomes of both approaches.
The main questions it aims to answer are:
if the anterior approach to the hip is faster recovery than lateral approach? if the anterior approach to the hip has better gait mechanics than lateral approach?
Participants will:
undergo one of the two approaches for total hip arthroplasty. All patients will be followed up at 2 weeks, 6 weeks, 3 months and 18 months. gait analysis will be done at 6wks, 3m, and 18months.

- Primary Outcome Measures
Name Time Method hemoglobin drop postoperative day one hemoglobin drop level between pre and postoperative.
hospital stays immediately after the procedure by ''Day'' as the unit, no special description. postoperative stay days from operation day to discharge day.
surgery time intraoperative time starting from skin incision to skin closure by ''Minute'' as the unit, no special description.
pain score 2 weeks 6 weeks 3 months 18 months using visual analogue scale (VAS) from 0-10 the more scale the worst the pain
Harris hip score 2 weeks 6 weeks 3 months 18 months for measuring hip function from 0-100 the more the score the better hip function
- Secondary Outcome Measures
Name Time Method gait analysis at 6 weeks, 3 months, 18 months A single experienced physical medicine specialist will perform the gait analysis in a gait lab. Three-dimensional kinematic and kinetic data will be collected using eight high-speed infrared cameras (Quality motion analysis system, oqus 1 cameras), which can capture 240 frames per second, two force plates (Advanced Mechanical Technology Incorporated, AMTI), and 26 ten-millimeter passive retroreflective markers fixed on the subject using a double-face tape in specific landmarks on the subject in accordance to the modified institute Orthopedic Rizzoli (IOR ) model for full body marker set.
