Variability in quadrupled hamstring tendon autograft diameter in North Indian population and its impact on anterior cruciate ligament (ACL) reconstruction outcomes

Abstract

Objectives: This study aimed to see the mean quadruple hamstring tendon (HT) graft in the North Indian population and the effect of height and gender on graft diameter. Materials and Methods: Three hundred and twelve patients who underwent anterior cruciate ligament reconstruction using quadruple HT graft with preserved insertions were included in the study. Quadruple graft diameter is calculated using a sizing tube and its correlation with height, gender, and body mass index was calculated. All patients were followed up for a minimum of 2 years, and the incidence of graft failure was calculated. Results: The mean graft diameter in the present study was 7.6 mm; taller patients and male gender have thicker grafts. About 63% of patients had graft diameters <8 mm. The incidence of graft failure rate was 2.5% and 0.8% in patients with graft diameters <8 mm and ≥8 mm, respectively. Conclusion: In the present study, the average quadruple HT graft diameter in the Indian population was 7.6 mm, and graft diameter depends on the height and gender of the patient.
