[Short-term results after STAR total ankle replacement]. / Frühergebnisse nach Implantation der STAR-Sprunggelenkprothese.

ABSTRACT

BACKGROUND: This retrospective study was performed to investigate the clinical and radiological results after STAR total ankle replacement. MATERIAL AND METHODS: Between January 2000 and September 2004, 49 patients with an average age of 62.5 years underwent total ankle replacement with the STAR prosthesis. At an average follow-up of 30.4 months, 48 patients were examined clinically and radiologically. The Kofoed ankle score and the patients' subjective satisfaction were evaluated. RESULTS: The operation improved the Kofoed ankle score significantly, from 28 to 86 points, 90% of the patients were satisfied with the results. The revision rate was 10%. CONCLUSION: The early results after implantation of the STAR ankle prosthesis are encouraging. With correct indication, a high rate of pain reduction and patient satisfaction can be achieved. The long-term benefit of this procedure has yet to be determined.
