The goal of our research is improve long-term outcomes following anterior cruciate ligament reconstruction. Persistent alterations in knee loading mechanics 6-24 months following surgery have been attributed to increased risk for re-injury and osteoarthritis. This study will determine the efficacy of a gait training intervention implemented in the early phases of recovery for improving knee loading mechanics long-term and will determine the feasibility of implementing and progressing the intervention during early rehabilitation following surgery. Improvements in knee loading as a result of the intervention will support the need for a paradigm shift in rehabilitation toward placing a greater focus on early interventions.
