Abstract

The purpose of this case was to assess the isokinetic strength adaptations of eccentric knee flexors (eccKF) and concentric knee extensors (conKE) in a professional male soccer player during anterior cruciate ligament (ACL) rehabilitation. Progress was monitored relative to a noninjured control group. Isokinetic strength assessments were initiated 18 weeks post ACL reconstruction and comprised assessments at eight angular velocities between 60–270°·s−1. The assessments ceased at the point where the player was cleared for return to play by his club 6 months after reconstructive surgery. The results identified that conKE peak torque of the treatment limb and eccKF peak torque of both lower limbs demonstrated meaningful changes. In addition, the eccKF angle of peak torque also demonstrated meaningful change that occurred at increased knee extension. The inclusion of additional angular velocities and angle-specific measures provide new insight into rehabilitation and return to play.
