According to current estimates, over 98% of hip and knee implantations are now recorded in SIRIS. In 2024, the revision rates of hip and knee implants used in Switzerland were transparently presented in the report for the sixth time in a row. Through the ongoing evaluation of implants, hospitals and surgeons, SIRIS has become an essential tool for quality assurance in prosthetics. Since 2015, there has been a visible trend towards decreasing revision rates across all total hip and knee replacements and all diagnoses.
