title: Can we use peroneus longus in addition to hamstring tendons for anterior cruciate ligament reconstruction?
abstract: BACKGROUND
  The aim of this study is to evaluate the possible effects of removing the peroneus longus on the ankle and gait parameters, in order to add insufficient hamstring tendons for anterior cruciate ligament (ACL) reconstruction.
  
  
  METHODS
  In this controlled clinical trial, 375 patients with ACL rupture who underwent ACL reconstruction arthroscopically using hamstring tendons in the orthopedic clinics of Isfahan University of Medical Sciences in 2010 and 2011 were selected. Fifteen patients were included because their hamstring tendon diameter was lower than 8 mm and peroneus longus was added. After 6 months, the patients were followed using "Kistler force plate" to detect 3D kinematics and kinetics of the ankles and spatiotemporal walking parameters.
  
  
  RESULTS
  There was a significant difference between both operated and non-operated ankles in flexion/extension range of motion (P < 0.05). There was no significant difference between the moments of both ankles in sagittal and coronal planes (P > 0.05), but there was a significant difference between the moments of both ankles in the transverse plane (P = 0.006). There was a significant difference in the force of operated and non-operated ankles in all three planes (P < 0.05). There was no significant difference in the mean values of spatiotemporal gait parameters between operated and non-operated sides (P > 0.05).
  
  
  CONCLUSIONS
  Removing the peroneus longus tendon has no effect on gait parameters and does not lead to instability of the ankle. So, it can be used as an autogenous graft in orthopedic surgeries.
