The following HT graft configurations were prepared in each patient: triple ST; double gracilis\u2009+\u2009double ST; double gracilis\u2009+\u2009triple ST; triple gracilis\u2009+\u2009triple ST. Paired t\u2010tests and Pearson\u2019s correlation coefficients were used to assess demographics, anthropometrics, graft diameter, and tendon length.
