 With extensive knowledge on running mechanics, it is important to consider these normal mechanics following ACL surgery.4, 5 Following ACL surgery and rehabilitation, several variances in gait pattern are known to exist for 6 months or greater. Several Studies have demonstrated abnormal knee torques following ACL surgery for well over 6 months.6 With known deficits lasting for several months, we must consider these mechanics and return to sport criteria when returning an athlete to sports competition. With the highest risk of reinjury in the first several months, understanding gait mechanics and risk factors is vital to a successful ACL rehabilitation.6 As a clinician, the most important aspect to consider a rehabilitation successful is an athletes full return to the sport or activity of their choice, at the highest level. In order to do this, we must understand all areas of their mechanics and limit any deficits throughout the process.
