Factors independently influencing changes in quadriceps strength and TUG in all participants (independent variable: knee swelling [1 cm])
| Dependent variables | Independent variables | Standardized β coefficient |
p |
|---|---|---|---|
| QW | Age (year) | 0.06 | 0.44 |
| Tourniquet time (min) | − 0.05 | 0.47 | |
| Knee swelling (1 cm) (%) | −0.23 | 0.00 | |
| ΔKnee pain during the QST (mm) | −0.17 | 0.03 | |
| ΔTUG | Age (year) | −0.04 | 0.60 |
| Gender | −0.07 | 0.39 | |
| Knee swelling (1 cm) (%) | −0.05 | 0.55 | |
| QW (%) | −0.29 | 0.00 |
Note. N = 173, male = 44. Standardized β indicates the adjusted regression coefficient. The Δ symbol indicates pre- and postoperative measurement changes
