Berdis AS, et al. - A cohort of patients (n = 194) ≤ 21 years of age, was retrospectively reviewed following anterior cruciate ligament (ACL) reconstruction with hamstring autograft tendon by the researchers in order to report on the outcomes of a subset of patients following ACL reconstruction coupled with biologic augmentation using platelet-rich plasma and a porous collagen carrier. International Knee Documentation Committee and Lysholm scores averaged 91 and 91 and the average Single Assessment Numeric Evaluation score was 94. The KT-1000 side-to-side variation averaged 1.2 mm. The average time to complete physical therapy was 22 weeks, and 132 patients came back to their preinjury level of competition. There were 23 and seven cases, respectively, of contralateral ACL injury and ACL reinjury obliging revision surgery. Thus, in ACL reconstruction, biologic augmentation with hamstring autograft exhibited a reduced rate of second ACL injury, especially relative to ACL revision surgery. The patients in this study also reveal a greater return to the preinjury level of competition at a faster rate in comparison with what other studies have explicated.
