Abstract:
BACKGROUND: Total hip replacement in middle-aged patients is challenging regarding restoration and survival,because these patients are more active than old patients.OBJECTIVE: To retrospectively investigate whether a cementless prosthesis could restore hip function,decrease osteolysis,wear,and enhance prosthesis survival in middle-aged patients.METHODS: Clinical and radiological evaluations of patients undergoing single-side total hip replacement with cement and cementless prosthesis were analyzed preoperatively as well as at 6 months,1,4 and 7 years postoperatively.The outcomes of total hip replacement were assessed using Harris hip scores and survival rate.End point was loosening or revision of the femoral component for any reason.RESULTS AND CONCLUSION: Cementless prosthesis had gained better Harris hip scores than that of cement prosthesis group at 6 months,1,4 and 7 years postoperatively(P < 0.05).The survival rate was greater in cementless prosthesis compared with cement prosthesis during 7-year follow-up(P < 0.05).Results have suggested that cementless prosthesis achieves high rate of functional restoration and a low rate of complications in middle-aged patients following total hip replacement.
