Abstract

Background: The doubled gracilis and semitendinosus tendon grafts are now effective options for knee ligament reconstruction surgery. The prediction of graft size by anthropometric measurements will help surgeons choose the appropriate method before surgery. Objectives: (1) Identifying some anthropometric parameters, diameter and length of the doubled semitendinosus and gracilis tendon; (2) Evaluating relationships between anthropometric parameters and these graft sizes. Material and methods: A cross-sectional descriptive study was carried out in 37 patients who underwent anterior or posterior cruciate ligament reconstruction by using the doubled semitendinosus and gracilis tendon from August 2020 to March 2021. Results: The average age was 33.78 ± 10.55 year-old; diameter and length of doubled semitendinosus and gracilis tendon graft: 7.24 ± 0.62mm and 10.81 ± 1.04cm, respectively. Patient weight was 64.30 ± 11.80kg, correlating with graft diameter (p < 0.001); patient height was 165.43 ± 8.11cm, correlating with graft length (p < 0.001). The regression equations for predicting the graft diameter and length: graft diameter(mm) = 4.764 + 0.039 x weight and graft length(cm) = 0.098 x height5.461 (p < 0.001). Conclusion: The anthropometric parameters correlate with graft sizes of fourstrand Hamstring tendon, which helps surgeons predict the graft sizes before operating.
