ABSTRACT
BACKGROUND:
Prompted by the success of hip and knee arthroplasty, total ankle replacement (TAR) has become increasingly popular as a treatment for end stage arthritis of the ankle. A 3-grade classification of complications to assist in prediction of early implant failure has been proposed. We have compared the experience of a tertiary referral center in the United Kingdom to the proposed system.METHODS:
A retrospective review of the Sheffield Foot and Ankle Unit TAR database was performed from 1995 to 2010. All complications were recorded and categorized using Glazebrook et al's proposed system of increasing severity. Low-grade complications including postoperative bone fracture, intraoperative bone fracture, and wound healing problems rarely lead to revision. Medium-grade complications, technical error and subsidence, lead to failure <50% of the time. High-grade complications--deep infection, aseptic loosening, and implant failure--lead to revision >50% of the time. In our center, 217 TAR were implanted in 198 patients with a minimum follow-up of 30 months.RESULTS:
The complication rate was 23%, with a revision rate of 17%. All complications recorded in our study except intraoperative bone fracture and wound healing had a failure rate of at least 50%.CONCLUSION:
Unfortunately most complications associated with TAR have a significant impact on the life span of a TAR. Glazebrook et al's proposed 3-tier system did not reliably reflect our experience. Hence, we would categorize complications as either high or low risk for early failure of TAR. LEVEL OF EVIDENCE Level IV, case series.Palavras-chave
