Purpose: The aim of this study was to analyse the long-term (>ten years) survival rate and radiological results of the Duracon TKA. Methods: Between 1992 and 1999 159 Duracon TKA were implanted at our institution. A Kaplan-Meier survival analysis for the endpoints exchange, addition or removal of any component for any reason, revision due to aseptic loosening and mechanical failure was performed. Radiological long-term (>ten years) follow-up (FU) analysis was performed according to the Knee Society Radiographic Evaluation and Scoring System. Results: Mean age at surgery was 74.3 years, 28 % were male, and 89 % had primary osteoarthritis as diagnosis. Mean FU for survival analysis was 10.9 years (SD 4.2). A total of 58 % of the patients died during follow-up. Three patients (2.1 %) were lost to follow-up and five TKA (3.1 %) were revised. After ten years the mean survival was 97.7 %, 99.4 % and 98.3 % for the aforementioned endpoints, respectively. Mean radiological FU was 11.8 years (SD 2.3). We found no significant change in alignment of the components or axis over time. Progressive radiolucencies were found in nine TKA (17 %), mainly around the tibial component (95 %). Conclusion: The Duracon TKA showed excellent long-term survival comparable to data from national registers and to other successful designs. Radiological changes found on plain radiographs were scarce after almost 12 years of radiological follow-up indicating good implant stability. [ABSTRACT FROM AUTHOR] |
