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 .
Changes in daily physical activity before and after total hip arthroplasty. A pilot study using accelerometry.
The present single-centre prospect i ve follow-up study assessed the objective changes in physical activity undertaken before and after  total hip arthroplasty ( THA ) using accelerometry . We enrolled 12 female patients who underwent home-based accelerometry assessment one month before and six months after the THA procedure .  We assessed the daily amount of physical activity and energy expenditure related to physical activities . We also recorded the intensity of the physical activity , and pre- and post-operative clinical evaluation with the Harris Hip Score ( HHS ) . At 6 months after surgery , we found a statistically significant increase of the total energy cost of physical activity ( DA ) ( P=0.02 ) , without significant increase of activity time ( P>0.05 ) . The energy cost of moderate/vigorous activity was statistically significant increased after surgery ( P=0.008 ) . Finally , HHS improved form 53.9±15.3 pre-operatively to 78.1±12.2 post-operatively ( P=0.03 ) . In our patients , the improvement was significant only for the total energy cost of daily activity . Thus , although patients did not exhibit a more active lifestyle , as shown by the slight increase of the activity time , they significantly increased the amount of moderate or vigorous activities performed after surgery
