Purpose : We evaluated the clinical results of arthroscopic ACL reconstruction using quadrupled hamstring tendon with tibial remnant-preserving technique.
Materials & Methods : Thirty-five cases were evaluated from Feb, 2003 to May, 2006. The average interval from injury to surgery was 2.6±1.6 months. The cause of injury was mostly sports-related trauma. The average follow-up period was 17 months. Tibial remnant was preserved as much as possible and caution was taken not to damage the remnant during ACL reconstruction. Postoperative rehabilitation was the same as the usual rehabilitation method after ACL reconstruction, except for delaying motion for 2 weeks with an extension locking brace. Clinical evaluation was performed using ROM; Lachman test; pivot-shift test; anterior displacement measurement using KT-2000 arthrometer; Lysholm score and proprioception measured by single limb standing test.
Results : There was no limitation of knee motion without contracture. The Lachman test and pivotshift test were both negative. The side-to-side difference of anterior displacement measured using KT-2000 arthrometer was improved from 6.7 mm to 2.2 mm. The average Lysholm score improved from 81 to 96. The single limb standing test for proprioceptive evaluation showed no significant difference from a normal leg.
Conclusion : ACL reconstruction with tibial remnant-preserving technique can preserve mechanoreceptors with prorioception and expect good functional recovery.
