title: Comparison of functional outcomes of two anterior cruciate ligament reconstruction methods with hamstring tendon graft.
abstract: OBJECTIVE
  The aim of this study was to compare the effects of Endobutton post-fixation and femoral (TransFix) transfixation in ACL reconstruction on lower extremity muscle strength, joint position sense, and knee stability.
  
  
  METHODS
  Subjects who had undergone ACL reconstruction with hamstring tendon using Endobutton post-fixation (n=20, mean age: 26.5 years) or femoral transfixation (n=20, mean age: 29.9 years) were recruited to an ACL rehabilitation program. Twelve months after surgery, quadriceps and hamstring torque values were recorded using an isokinetic dynamometer. Computerized coordination and proprioception tests (Functional Squat System; Monitored Rehab System) were performed to determine the deficits in joint position sense. The anterior translation test was performed using a Kneelax 3 arthrometer to determine knee laxity.
  
  
  RESULTS
  Side-to-side differences between groups for hamstring and quadriceps muscle strength, concentric and eccentric motor coordination and anterior tibial laxity were not significantly different (p>0.05).
  
  
  CONCLUSIONS
  No statistically significant differences in functional outcome were found 1 year after the ACL reconstruction using Endobutton post-fixation and femoral transfixation with hamstring tendon graft. Deficits in hamstring-quadriceps muscle strength, motor coordination and proprioception were still found in both groups. We therefore recommend that long-term follow-up and rehabilitation including neuromuscular exercises should be continued for longer than one year after ACL reconstruction.
