Peak PFJ Contact Force, Knee Flexion Angle at Peak PFJ Contact Force, and Quadriceps Force at Peak PFJ Contact Force a
| Peak PFJ Contact Force, BW | Knee Flexion Angle, Deg | Quadriceps Force, BW | |
|---|---|---|---|
| ACLR | 12.7 (11.3-14.1) b | 52 (49-54) b | 10.9 (10.0-11.7) b |
| Contralateral | 18.7 (17.4-20.0) | 56 (54-58) | 15.1 (14.3-16.0) |
| Control | 17.1 (15.7-18.5) | 57 (55-60) | 13.7 (12.8-14.6) |
a
Data are presented as marginal means (95% CI), accounting for approach velocity during the side-step cut. ACLR, anterior cruciate ligament reconstruction; BW, body weight; PFJ, patellofemoral joint.
b
Significant difference compared with contralateral and control limbs (P < .05).
