Assessment of flexion strength following single- vs double-hamstring tendon harvest for anterior cruciate ligament reconstruction
Arthroscopy May 07, 2020
Hu A, Lawton CD, Nelson P, et al. - Patients who underwent anterior cruciate ligament (ACL) reconstruction with doubled semitendinosus and gracilis tendon autograft (ST/G) vs quadrupled semitendinosus autograft (ST) were compared concerning isometric hamstring strength deficits, knee laxity, functional outcomes, and patient-reported outcomes, at a minimum follow-up of 1-year postoperatively. Researchers assessed 84 patients who underwent ST/G (n = 34) or ST (n = 50) autograft ACL reconstruction in this study. Outcomes revealed a significantly greater isometric flexion strength deficit at 90° of flexion among patients who underwent ACL reconstruction with ST/G vs ST autograft. Aside from a significant difference in the KOOS pain Score, they identified no other significant differences in functional or patient reported outcomes between the groups.
