No Deficits in Functional Outcomes of the Contralateral Limb Are Seen When the Hamstring Is Harvested for Augmentation of Small Diameter Ipsilateral Hamstring Autograft

PurposeTo evaluate clinical outcomes of the contralateral, nonoperative limb in patients undergoing contralateral hamstring (HS) autograft harvest compared with ipsilateral HS alone.MethodsThis study included 96 who underwent isolated anterior cruciate ligament reconstruction (ACLR) using 4-stranded (n = 85) or augmented 13) due to inclusion graft diameter <8 mm. Isokinetic flexion and extension strength dynamic performance limbs symmetry index (LSI) were evaluated at 6 months’ postoperatively. Rates native ACL tear minimum 2 years also compared. For all comparisons, P < .05 was considered statistically significant.ResultsNormalized isokinetic knee did not differ between cohorts (P .34; .21, respectively).
