Predictive Factors for a Successful Return to Run After ACL-R

After anterior cruciate ligament (LCA) rupture, the recommended treatment for athletes is the surgical reconstruction of the ligament (ACL-R), followed by a long rehabilitation period. The results of this treatment are sub-optimal with a low rate of return to pre-injury level of sport, a high risk of reinjury and early knee osteoarthritis. To improve treatment outcomes, researchers and clinicians recommend optimizing rehabilitation protocols. They recommend individualizing rehabilitation progression based on objective criteria. However, current defined criteria relied on experts' opinions and not scientific validation.

Return to run after ACL reconstruction is an important rehabilitation milestone. It often means the beginning of the return to sport continuum. A successful return to run is therefore crucial for both the patient and clinician. In this study, the investigators aim to determine the predictive outcomes for a successful return to run after ACL-R.
