Aim: Knee arthroplasties, both total (TKA) and unicondylar, as well as high tibial osteotomy (HTO) represent the main treatment options in severe osteoarthritis of the knee. The aim of this study was to collect detailed information regarding the current treatment strategies in Germany. Methods: 220 departments of orthopaedic surgery and 250 departments of trauma surgery were asked about their treatment strategies in an anonymous nation-wide survey regarding the different operative procedures in HTO, TKA, revision TKA and related issues. Univariate analyses were performed and means, medians and rates were calculated. Results: Questionnaire forms were answered by 54% of the departments. The survey represents 31138 TKA for the year 2002. In the mean 137 TKA were performed in each department. Posterior cruciate ligament retaining components were used in 67%, resurfacing of the patella was performed in 19% of cases. The incidence of revision TKA is about 10% compared to the primary TKA cases. In comparison to a different survey from the year 1995, the absolute number of primary and revision TKA has increased by a factor of nearly three. Compared to the number of TKA, the proportion of HTO has declined to 12% and the number of unicondylar knee arthroplasties represents 7% of all cases. Conclusion: In the surgical treatment of severe osteoarthritis, TKA shows a highly increasing number, whereas HTO is decreasing. An increasing number of revision TKA can be observed. There is trend towards the cemented implantation technique. Patella resurfacing is not performed routinely in most German hospitals.
