Seventy patients undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) were randomly assigned to receive ACLR alone or ACLR plus a lateral extra-articular tenodesis (LET). Our primary outcome was Limb Symmetry Index (LSI) calculated using a series of four hop tests at six months postoperative. Secondary outcomes measures included pain, subjective function and isokinetic strength testing. We found no statistically significant difference between the two groups in LSI calculations. We found statistically significant differences favouring the ACLR alone group in quadriceps average power and peak torque symmetry measurements at six-months postoperative when we adjusted for baseline measurements. No other statistically significant differences were found. This thesis presents the six-month preliminary results of a larger continuing study and at this time no definitive conclusions can be made.
