Abstract
Purpose
To evaluate the clinical outcomes of an anterior cruciate ligament reconstruction using autologous hamstring tendons with stable fixation.
Materials and Methods
Seventy-six ACL reconstructions using autologous hamstring tendons were reviewed for an average of 16.5 months (Range, 12-35.6 months) postoperatively. All the patients were examined using standard clinical techniques and evaluated by stress radiography, Cybex™, Lysholm score, and International Knee Documentation Committee (IKDC) ratings.
Results
In all cases, there were no limitations in the range of motion. The mean Lysholm score was 72.9 preoperatively, which later improved to 91.1 postoperatively. According to the IKDC grade, 74 cases were categorized as 'normal' or 'nearly normal' postoperatively. In addition, the Cybex™ study showed that at an angular velocity of 60°/sec, the strength deficit of the hamstrings decreased to 16% from 24% while the strength deficit of the quadriceps decreased to 27% from 31%. The mean side-to-side difference in stress radiography was 2.4 mm postoperatively. There was a single case of graft failure resulting from a deep infection.
