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.
