In this study, researchers from the Gait and Posture Lab at the University of Montreal in Canada compare walking patterns between patients who had a total hip replacement versus a surface replacement arthroplasty . An earlier study by Mont et al comparing these two groups reported a slower walking speed and decreased muscle force in the hip abductor muscle of the hip. Results for the patients in the previous study were reported for six to 18 months after surgery. The effects of different implants on gait pattern were measured six to eight months after surgery in this study. The authors thought that a tighter time frame might give them a better way to compare these two patient groups. Hip joint resurfacing was introduced several years ago to help younger patients who are more active and who would likely dislocate or wear out a total hip replacement. Surgeons found a way to replace the surface of the joint without removing the bone and replacing the entire joint. Bone is saved because the...
