Aim. This study aimed to compare the clinical outcome of anatomical single-bundle (SB) and double-bundle (DB) Anterior Cruciate Ligament (ACL) reconstruction.
Methods. ACL reconstruction with hamstring tendons autograft was performed for 118 patients; 68 and 50 patients by their tendency underwent anatomical SB and DB reconstruction, respectively. Patients were evaluated via KT-1000, IKDC (International Knee Documentation Committee), Extension limitation, Lachman test, Pivot-Shift test and Lysholm score.
Results. Eighteen months postoperation, 110 patients (64 in SB and 46 in DB) completed the follow-up assessment. Using KT1000 arthrometer, the side-to-side difference in anterior tibial translation was 1.5±1.4 mm in the DB and 2.1±1.4 mm in the SB group (P=0.028). Additionally, the objective IKDC (International Knee Documentation Committee) scores showed significantly more “normal knees” in DB than SB group (P=0.047). The Lachman test was negative in 89% and 75% of cases in DB and SB groups respectively. There was no difference between two groups in the Lysholm score.
Conclusion. Despite no significant difference between DB and SB reconstruction in terms of Lysholm or pivot-shift testing, this study demonstrated a significant advantage in KT 1000 arthrometer as well as objective IKDC for DB reconstruction compared to SB reconstruction.
