To describe physical function before and six months after Total Knee Replacement (TKR) in a small sample of women from China and the United States.
Observational.
Community environment.
Both groups adhered to the Osteoarthritis Research Society International (OARSI) protocols for the 6-minute walk and 30-second chair stand. We compared physical function prior to TKR and 6 months after using linear regression adjusted for covariates.
Women (N=60) after TKR.
Not applicable.
Age and body mass index in the China group (n=30; 66y and 27.0kg/m
Despite having worse physical function before TKR, the China group had greater gains in walking endurance and similar gains in repeated chair stands than did the U.S. group after surgery.
