Author, year | BMI: mean (SD) | Measure | Results |
Ollivier et al, 201273 | 25.13 (3.14)* | HHS/HOOS | |
Pietschmann et al, 201375 | 28.4 (4.62)* | OKS | At long term, physical activities were not related to complications (P<0.01). Physically active patients had less pain and better OKS scores after UKA. |
Poortinga et al, 201476 | 28.7 (4.9) | WOMAC | At long term, physical activity was not associated with WOMAC score (P>0.05) after THA or TKA. |
Sechriest et al, 200779 | 28.1 (8.3) | UCLA | At long term increased BMI was not correlated to UCLA physical activity score (r=−0.07; P=0.67) after TKA. |
