Background: Excellent midterm results for total hip arthroplasties (THA) with cementless, tapered porous Taperloc® femoral stems have been reported. Reports regarding such cemented stems, however, are lacking. Objectives: To evaluate the long-term outcomes of both cemented and cementless THAs with the Taperloc femoral component. Methods: The medical records of 71 patients (76 hips), operated on between January 1991 and December 2003, who had a minimum follow-up of 10 years were available for analysis. Functional analysis was performed with the Harris hip score (HHS) questionnaire and the numerical analogue scale (NAS). Radiographic analysis was performed for subsidence, radiolucent lines and osteolysis. Results: The cohort was comprised of 47 female and 24 male patients, with a mean age of 59.7 ± 12.4 years. The mean follow-up was 17.8 ± 4.4 years. 52.6% of THAs analyzed were cementless and 47.4% were cemented. Post-operative radiographs were available for 57 surgeries. Subsidence, hypertrophic ossification, radiolucent lines and osteolysis were noted in 4 (7%), 2 (2.6%), 14 (18.4%) and 11 (14.5%) hips respectively. The average HHS score at a mean follow-up of 20.1 ± 3.9 years was 62.1 (±27.7) and the NAS score was 4.6 (±3.6). During the study period, five revision surgeries were performed due to stem-related problems, one of which was for aseptic loosening. Conclusions: Our long-term experience with the Taperloc stem, both cemented and cementless, demonstrates good outcomes, with low rates of failure. This makes this prosthesis an attractive option for THAs. Level of Evidence: IV
Key words: Taperloc / Total hip arthroplasties / Surgery, survival, long-term outcomes
