Total hip arthroplasty (THA) is undertaken to relieve pain and to restore mobility. The orthopaedic community remains divided on the influence of surgical approach in achieving functional recovery most quickly and effectively. We report a study comparing THA performed through a posterior (Posterior) against anterior approach (Heuter). Fifty patients were prospectively enrolled and randomized for Posterior or Heuter procedures. Informed patient consent and local ethics approval was obtained. All patients received an uncemented, ceramic-on-ceramic prosthesis performed by a single surgeon. Functional outcome was assessed by time to achieve milestones of walking, stair climbing, hip movement and balance. Kinematic data on level-ground walking and the effect of fatigue was assessed using a portable gait analysis system at 6-, 12-, and 24-weeks post-operatively.Introduction
