Standing Flexion Angle Characteristics in Patients Following Ipsilateral Hamstring Tendons Autograft Anterior Cruciate Ligament Reconstruction

Our primary aim was to profile standing flexion angle responses to ipsilateral hamstrings tendons autograft ACL reconstruction in physically active patients. A retrospective cohort of 15 patients (age = 21.2 + or - 2.6 years, height = 1.7 + or - 0.1 m, mass = 68.7 + or - 12.6 kg, Tegner = 6.9 + or - 1.6) 27.5 + or - 10.9 months post-surgery were matched to 15 healthy control participants (age = 21 + or - 1.1 years, height = 1.6 + or - 0.1 m, mass = 67.4 + or - 10.3 kg, Tegner = 6.3 + or - 1.3) and assessed in a laboratory setting. Significant correlations existed among subjective subscale scores and standing flexion angle (KOS-ADLS Symptoms: r = 0.578, P = 0.024; KOS-ADLS Function: r = 0.578, P = 0.024; KOOS Symptoms: r = 0.553, P = 0.033; KOOS Pain: r = 0.785, P = 0.001; KOOS Function: r = 0.683; P = 0.005; KOOS Sports: r = 0.520; P = 0.047) for the involved leg.
