Physical activity did not change at 6 months , and a small to moderate improvement was found at 12 months postsurgery , despite large improvements in quality of life , pain , and physical function .
Reasons for the lack of increased PA are unknown but may be behavioral in nature , as a sedentary lifestyle is difficult to change .
OBJECTIVE Little is known about the extent to which  physical activity ( PA )  levels change following total knee or hip joint replacement relative to pain , physical function , and quality of life .
Our objective was to conduct a systematic review and meta- analysis on changes in PA relative to pain , quality of life , and physical function  after total knee or hip joint replacement .
Quality of life and functional outcome after primary total hip replacement. A five-year follow-up.
We have evaluated the quality of life and functional outcome after  unilateral primary total hip replacement ( THR ) . Between 5 January 1998 and 31 July 2000 , we recruited a consecutive series of 627 patients undergoing this procedure and investigated them prospect ively . Each was assessed before operation and review ed after six months , 18 months , three years and five years . The  Short Form-36 Health Survey ( SF-36 ) and Harris Hip scores  were evaluated at each appointment . All dimensions of the SF-36 except for mental health and general health perception , improved significantly after operation and this was maintained throughout the follow-up . The greatest improvement was seen at the six-month assessment . On average , women reported lower SF-36 scores pre-operatively , but the gender difference did not continue post-operatively . The Harris Hip scores improved significantly after operation , reaching a plateau after 18 months . The improved quality of life was sustained five years after THR
