Gait characteristics for groups during walking.

No PFOA (N = 24) Mild PFOA (N = 38) Severe PFOA (N = 44)
Knee flexion angle at heel contact (degrees) 3.5 (5.8) 6.1 (6.5) 5.0 (6.6)
Peak loading response knee flexion angle (degrees) 17.5 (6.0) 18.3 (6.9) 14.9 (5.6)†
Loading response knee flexion excursion (degrees) 14.0 (4.7) 12.2 (5.3) 10.0 (4.8)*
Peak single leg stance knee flexion (+)/extension (−) angle (degrees) 4.0 (5.9) 7.4 (8.0) 5.8 (5.7)
Peak loading response external knee flexion (+)/extension (−) moment (Nm/kg) 0.6 (0.4) 0.6 (0.4) 0.6 (0.4)
Peak single leg stance external knee flexion (+)/extension (−) moment (Nm/kg) −0.06 (0.4) 0.08 (0.3) 0.1 (0.3)*

PFOA = Patellofemoral Osteoarthritis; Values are mean (SD).

All analyses were adjusted for gender, BMI and radiographic tibiofemoral joint disease severity.
