Summary

Inferior outcomes are often noted following revision anterior cruciate ligament reconstruction (ACLR) compared with primary ACLR. This finding is supported by a consensus of ∼?90 authors in the Multicenter ACL Revision Study (MARS) Group, as well as a number of studies [Wright RW et al. J Bone Joint Surg Am 2012; Wright R et al. J Knee Surg 2011; Spindler KP et al. J Bone Joint Surg Am 2005].
