Abstract / Description of output

We reviewed 100 patients retrospectively following primary ACL reconstruction with quadruple hamstring autografts to evaluate the incidence and factors associated with postoperative stiffness. Stiffness was defined as any loss of motion using the contra-lateral leg as a control. The median delay between injury and operation was 15 months.

The incidence of stiffness was 12% at 6 months post-reconstruction. Both incomplete attendance at physiotherapy (p<0.005) and previous knee surgery (p<0.005) were the strongest predictors of the stiffness. Anterior knee pain was also associated with the stiffness (p<0.029). Factors that failed to show a significant association with the stiffness included associated MCL sprain at injury (p=0.32), post-injury stiffness (p=1.00) and concomitant menisectomy at reconstruction (p=0.54). Timing of surgery also did not appear to influence the onset of stiffness (median delays: 29 months for stiff patients: 14 months for non-stiff patients). The rate of stiffness fell to 5% at 12 months postreconstruction, without operative intervention. (C) 2008 Elsevier B.V. All rights reserved.
