There were no restrictions regarding study design.Results: 31 articles addressing this topic using various quality-of-life evaluation proto-cols were selected. SF-36/SF-12, WOMAC and Oxford were the ones most frequentlyused. The studies made it possible to define that TKA is capable of making an overall mprovement in patients quality of life.
