BACKGROUND: Total talar replacement has been reported to have favorable short-term and intermediate-term results for the treatment of osteonecrosis of the talus. The purpose of this study was to evaluate the long-term clinical results of total talar replacement for a minimum of 10 years after the surgical procedure.
METHODS: From October 2005 to April 2011, 19 ankles in 18 patients (1 male and 17 female) were treated using a total talar prosthesis for osteonecrosis of the talus. The median follow-up period was 152 months (interquartile range [IQR], 138, 160 months). The Ankle Osteoarthritis Scale (AOS) score, the Japanese Society for Surgery of the Foot (JSSF) Ankle-Hindfoot Scale score, and the presence of osteophytes and degenerative changes in the adjacent joints were assessed preoperatively and at the final follow-up. Subsidence of the prosthesis was also assessed at the earliest opportunity for full weight-bearing and the final follow-up. The postoperative range of motion of the ankle was assessed at the final follow-up.
RESULTS: The median scores for all subscales of the AOS significantly improved. The median JSSF Ankle-Hindfoot Scale score significantly improved from 58 (IQR, 55, 59.5) to 97 (IQR, 87, 99.5). In the subcategories of this scale, the median pain score improved from 20 (IQR, 20, 20) to 40 (IQR, 30, 40), and the median function score improved from 28 (IQR, 26, 30.5) to 47 (IQR, 47, 50). The median postoperative range of motion of the ankle was 45° (IQR, 42.5°, 55°). Subsidence of the implant was not recognized at the final follow-up (p = 0.083). Proliferation of osteophytes and degenerative changes in the adjacent joints did not affect the overall results.
CONCLUSIONS: The customized alumina ceramic total talar prosthesis produced stable clinical outcomes over 10 years, and the patients treated with total talar replacement showed favorable clinical results over this time frame.
LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
