During the first 4 weeks after surgery, significant quadriceps strength deficits, when compared to the contralateral limb, have been ,28 Although knee stability is significantly improved, long-term outcomes report knee extensorweakness ranging from 6%12 to 18%23 as late as 1 to 6 years following reconstruc-tion. Ernst et al8 further demonstrated that persistent lower extremity compen-sations exist following ACL reconstruc-tion and adversely affect single-limb performance, including vertical jump takeoff and landing. Other investiga-tors12 found that patients following ACL reconstruction who had knee extensor strength less than 80% of the contralat-eral side had gait kinematics similar to patients with ACL-deficient knees.
