This study aims to evaluate midterm clinical results of the use of two autogenous graft types.
Patients and methods: Between June 2005 and November 2010, clinical data of 44 patients who were operated were retrospectively analyzed. Quadriceps tendon-patellar bone autograft was used for reconstruction surgery in 23 patients (QT-PB group), while quadrupled hamstring tendon autograft was used in 21 patients (HT group). The Tegner’s activity scale, Lysholm scoring system, single-leg-hop test and KT-2000 arthrometric measurements were used for data collection.
Results: The mean length of follow-up was 37.6 months. Although the mean Lysholm score increased in both groups, excellent results in HT group were two-fold higher compared to QT-PB group. The mean laxity for the operated knee joint was 5.65 mm (3.5 to 8.0 mm) in QT-PB group and 3.67 mm (3.0 to 5.5 mm) in HT group. Head-to-head analysis using KT-2000 arthrometer demonstrated that 12 patients (52.1%) in QT-PB group and two patients (9.6%) in HT group had more than 3 mm of anterior laxity difference.
Conclusion: Quadrupled hamstring tendon autograft is superior to central quadriceps tendon-patellar bone in arthroscopic anterior cruciate ligament reconstruction surgery.
