Researchers at the Hopital Maisonneuve-Rosemon in Montreal, Canada studied 205 patients who had undergone hip arthroplasty to determine the ability of patients to engage in sports activities postoperatively. Wearing of the prosthetic metal-polyethylene using in hip arthroplasty is related to patient activity, so intense and repetitive movement may be discouraged. In the study, researchers compared total hip arthroplasty patients against resurfacing hip arthroplasty, and the difference in the degree of physical activity engaged in by the two groups. Due to the excellent joint stability of hip resurfacing, patients of this procedure reported greater engagement in sports activities, and at a greater intensity than patients of total hip arthroplasty. However, the long-term effects of intense physical activity on the metal components used in hip arthroplasty are not certain.
