Primary Outcome Measures

Name	Time	Method
Gait analysis - 12-camera VICON system with Bertec force plates and IMeasureU inertial sensing units.<br><br>Composite Outcome - full 3D kinematic and kinetic analysis, so the outcome measures include:<br>- double support time, walk ratio, variability of step velocity, and single support asymmetry.<br>- hip, knee, ankle joint angles and joint moments (peak values, ROM, and integrated values)<br>- The inertial sensors will give us an impact loading measurement (we call it a bone stimulus metric) and a measure of asymmetry[Base line pre operative, 1 month postoperative (primary timepoint), 2 months postoperative];Physiotherapy outcomes - supine straight leg raise[Base line pre operative, 1 month postoperative (primary timepoint), 2 months postoperative];Radiographic outcomes - acetabular inclination (well aligned 35-50 degrees), [Immediate post operative Xray]
