Abstract

The knee arthroplasty register was established in Vreden Russian Research Institute of Traumatology and Orthopedics on 01.01.2011 and during the following 3 years the data about 6530 primary (91,7%) and revision (8,3%) cases were collected. The average age of patients was 62,72 ±11,5 years with the prevalence of women both in primary (80%) and revision (70%) arthroplasty cohorts. The main group consisted from the patients with knee osteoarthritis (92%) with annual growth of the obese. Total cemented knee replacement without patella resurfacing was the most popular type of primary arthroplasty (96%) with the prevalence of PCL retaining implants (62,13±3,84%). Despite annual decrease of revisions due to infection they predominate under aseptic cases: in 2011 - 64,7% and 35,3%, in 2012 - 62,8% и 37,2% , in 2013 - 53,1% and 46,9% accordingly. The main reason for non-infected revision TKA was implant loosening (17%). This is the first attempt to describe the trends in knee arthroplasty based on data from register of Russian Research Institute of Traumatology and Orthopedics. It’s structure allows to perform multifactorial analysis of knee replacement surgeries and in the future to evaluate implants survival rate.
