Clinical outcomes of cementless total hip replacement in coxarthrosis

Purpose: The outcomes of cemented, cementless and hybrid fixation options in total hip replacement are still controversial. The aim of our study is to evaluate the clinical and radiological results of our cementless total hip replacement cases compared with the literature. Materials and Methods: We evaluated 80 patients' 95 cementless total hip arthroplasties retrospectively. The minmum follow up periodwas 12 months. We used the Harris Hip Score (HHS) for clinical evaluation. We evaluated malposition, aseptic loosening, heterotopic ossification, dislocation and other complications by direct radiography. Results: Forty seven (58.7%) of the patients were female and 33 were male (41.3%). Mean age of the patients was 52.3 +/- 12.8 years. Thirtysix (45%) of the patients were operated in the right hip, 29 (36%) of the patients were operated in the left hip and 15 (18.7%) of the patients were operated bilaterally. Posterolateral incision was used in 74 (77.9%) patients and posterolateral incision was used in 21 (22.1%) patients. Mean follow up was 38 +/- 18.8 months. Total Harris hip scores of the patients before and after surgery were 28.52 +/- 10.93 and 87.09 +/- 7.03, respectively. There was acetabular malposition in 12 patients. Eight patients had intraoperative fractures. Conclusion: Cementless total hip arthroplasty provided good clinical outcomes in Harris Hip Score evaluation in short to-medium-term. Rigid cementless fixation in early period can be achieved but, caution is advised against intraoperative fracture and acetabular component malposition.
