Hamstring antagonist torque generated in vivo following ACL rupture and ACL reconstruction

Abstract

Hamstring motor behaviour and resultant antagonist torque during knee extension has been quantified in uninjured individuals however, the effect of ACL rupture and ACL reconstruction (ACLR) on the morphology of hamstring antagonist torque generated in vivo is unknown. The purpose of this cross-sectional study was to quantify the hamstring antagonist torque generated in vivo during isokinetic knee extension in ACLD and ACLR patients relative to uninjured control subjects. Ten male ACL deficient (ACLD) subjects (18-35. years), 14 matched males who had undergone ACLR using the bone-patellar tendon-bone graft and 22 matched male control subjects participated. We used a mathematical model to esti..
