The data from the Swiss National Joint Registry SIRIS is clear: Schulthess Klinik’s high degree of specialisation and extensive experience has a direct beneficial impact on patient outcomes. Within two years after a hip or knee replacement operation, significantly fewer Schulthess Klinik patients require revision surgery than is the average in clinics across Switzerland. With hip replacements, Schulthess Klinik’s rate is 1%, whilst for knee replacements the figure is 1.1%. This is over two and a half and three times lower than the Swiss average respectively.
