The New Zealand Joint Registry: report of 11-year data for ankle arthroplasty.

Abstract

This article describes the results of the first 11 years of ankle arthroplasty data for the New Zealand Joint Registry. The main purpose is to collect accurate outcome information regarding these procedures and to guide orthopedic surgeons in the care of their patients. Trends can often be identified early, and implants with higher revision rates can be identified. In addition, individual surgeons can be given data that compare their performance with the collective data, providing invaluable feedback. Patient-based questionnaires are highly important for gauging the results of surgery. Patient response rates have been less than optimal, particularly after revision surgery.
