Purpose:The purpose of this study was to investigate the distribution of the diameter of four strand autologous hamstring tendon and to identify the factors related to the diameter.
Materials and Methods:Between December 2004 and July 2006, 66 patients underwent anterior cruciate ligament reconstruction using autologous hamstring tendon. Sixty one patients were male and the other 5 patients were female. Both semitendinosus and gracilis tendon were harvested in every case. Harvested two tendons were folded once together to create a four strand double loop graft and were passed through cylindrical sizer to measure their diameter. Parameters such as sex, age, height and weight were analyzed for their correlation with the diameter of the graft.
Results: The diameter of the graft ranged from 6 mm to 10 mm. The graft with the diameter of 8 mm was most common and the average diameter of all the grafts was 7.85±0.92 mm. Seven patients (10.6%) had a graft with the diameter of 6 mm, which is considered too thin to be ideal one. No statistically significant correlation was found between age of the patient and the diameter of the graft. However, the diameter of the graft was significantly correlated with sex, height and weight of the patient. Female patients had a significant tendency to have thinner hamstring tendons. Both small height and light weight of the patients were correlated with thinner hamstring tendons significantly.
Conclusions:Sex, height and weight of the patients were the factors that had a statistically significant correlation with the diameter of the graft. Being aware of the risk factors related with harvesting exceedingly thin hamstring tendon prior to anterior cruciate ligament reconstruction, one can utilize wide range of options in selecting an optimal graft.
