Gait Analysis and Clinical Outcomes of Anterior and Lateral Approach Total Hip Arthroplasty.

Not Applicable
Completed
Conditions
Hip Osteoarthritis
Interventions
Procedure: total hip replacement using lateral approach
Procedure: total hip replacement using anterior approach
Device: 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.

Secondary Outcome Measures

gait analysisat 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.
