Fig. 1A–B.

Knee flexion contractures caused by 8 weeks of immobilization were not reversed by 4 weeks of remobilization. Contractures are calculated as the ROM lacking in extension of the surgically treated knee (sham or immobilized group) minus the ROM lacking in extension of the contralateral knee (sham or immobilized group) (data presented in Table 1) at two torque values: (A) Torque 1 = 667 g/cm and (B) Torque 2 = 1060 g/cm. Muscle on refers to results calculated from data on the intact knee; muscle off refers to results calculated from data on the knee after the skin and transarticular muscles were removed. Error bars represent standard error of the mean. ^* = p ≤ 0.05 between immobilized and sham-operated groups.
