Total knee arthroplasty procedure is one of the most commonly performed orthopeadic procedures in Lithuania. A number of factors have a certain influence on treatment results. The aim of this study was to assess patient‘s sex, age, and operating approach affect on revision surgery rate for patients undergoing a total knee replacement. The study included all Lithuanian arthroplasty registry database records of primary knee arthroplasty cases since January 1st of 2011 to the December 31st of 2013 and further follow up untill December 31st of 2014. All the revision cases were also recorded. The main evaluation criteria was implant survival rate after the initial surgery. According to the survey, during the period of 2011-2013 there were 4436 knee arthroplasties performed for women and 1119 for men. The medial parapatelar approach was used in majority of cases (88%). There were 59 revisions registered during the same period that represents a total of 1.1%. Knee implant survival rate was 98.9% after an average of 30 months. A slightly better results after arthroplasty were observed for male patients (99.0%), comparing to female patients (98.9%), however the difference was not statisticaly significant. Comparing knee implant survival rate between two age groups the worse implant survival rate was found in patients younger than 60 years age group (98.4%), comparing to 99.1% in patients older than 60 years of age.
