Objective: 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.
Design: Observational.
Setting: Community environment.
Outcomes: Both groups adhered to the Osteoarthritis Research Society International (OARSI) protocols for the 6-minute wallc and 30-second chair stand. We compared physical function prior to TIM and 6 months after using linear regression adjusted for covariates.
Participants: Women (N=60) after TKR.
Interventions: Not applicable.
Results: Age and body mass index in the China group (n=30; 66y and 27.0kg/m(2)) were similar to those in the U.S. group (n=30; 65y and 29.6kg/m(2)). Before surgery, the China group walked 263 (95% confidence interval [CI], 309 to 219) less meters and had 10.2 (95% CI, -11.8 to -8.5) fewer chair stands than the U.S. group. At 6 months when compared with the U.S. group, the China group wallced 38 more meters, but this difference did not reach statistical significance (95% CI, -1.6 to 77.4), and had 3.1 (95% CI, -4.4 to -1.7) fewer chair stands. The China group had greater improvement in the 6-minute walk test than did the U.S. group (P<.001).
Conclusions: Despite having worse physical function before TICR, the China group had greater gains in wallcing endurance and similar gains in repeated chair stands than did the U.S. group after surgery.
