Outcomes and Complications of Total Hip Replacement in Patients over 65 Years of Age (A Comparison Between Cemented and Cementless Techniques)

Cementless total hip replacement is an accepted alternative to total hip replacement with cement in younger patients، but it remains controversial for elderly patients. This study evaluated the functional results and complications of cemented and cementless methods in old patients. In this cross-sectional study، all the patients aged 65 years or older who had been hospitalized for total replacement of hip joint because of femoral neck fracture or osteoarthritis of hip were studied during a 3-year period in three educational hospitals in Iran. «Harris hip score» was used to assess the functional consequences. The early complications -thrombophlebitis of lower limbs، dislocation، hematoma and infection - and late complications - aseptic loosening، dislocation، and reoperation، were documented. 209 eligible patients، including 96 (45. 9%) cemented and 113 (54%) cementless were studied. Patients were followed for a mean period of 5 years and 2 months (51-82 months). The overall rate of early complication was 8 cases (3. 8%): five in the cemented and three in cementless group، respectively. Late complications were seen in two cases -one loosening in cemented group and one dislocation in cementless group. The final Harris hip score at the final follow-up was 84. 01±4. 71 in cemented and 85±5. 02 in the cementless groups (p≥. 05). Cementless hip replacement can have a satisfactory functional result like cemented hip replacement procedure in the elderly patients over 65 years of age.
