Brief Summary

Anterior cruciate ligament (ACL) is a frequent and disabling injury in athletes. Most of the time, ACL reconstruction (ACLR) is consider for regaining function and returning to preinjury sports while reducing the risk of secondary injuries. However, the risk of secondary severe knee injury is increased after ACLR, especially in athletes returning to strenuous activities. If strength symmetry is considered as an important factor in the Return-to-sport (RTS) decision, there is conflicting data about the association between strength symmetry and the risk of second knee injury after ACLR. The main objective of this study was to test if knee muscles strength symmetry at 4 months was associated with the psychological readiness and incidence of subsequent severe injury of both knees at a minimum 2 years follow-up after ACL-R.
