Second, to test whether the "clinically failure” value of KOOS quality of life (QoL)<44 was indicative of a clinically relevant difference in the risk of subsequent revision ACLR. Methods: ACLRs reported to the Norwegian Knee Ligament Registry between June 2004 and December 2009. 5,517 primary ACLRs with at least 2-year follow-up with KOOS QoL before revision surgery. Results: There were clinically significant differences, adjusted and unadjusted, in both the KOOS Sport and Recreation and QoL subscales in patients with a later revision surgery compared to those that did not have a revision surgery. In adjusted models, the risk of later ACLR revision was 3.7 (95% CI 2.2-6.0) higher in patients with a 2-year KOOS QoL<44 compared to patients with a KOOS QoL≥44. For every 10-point reduction in the KOOS QoL, a 33.6% (95% CI 21.2-47.5%) higher risk for later ACLR revision was observed. Conclusions: This study reveals an association between inadequate knee function, as measured by KOOS, and a prospective ACL-reconstructed graft failure. Level of evidence: Prognostic study (prospective cohort study), Level II.
