Inclusion criteria included any patient undergoing knee arthroscopy. Patients with a confirmed ACL tear were allocated to either the ACL tear with cartilage injury group or the ACL tear without cartilage injury group based on intraoperative assessment. Patients who underwent an arthroscopic procedure with no injury history or symptoms in their contralateral knee were asked to provide samples to serve as healthy controls. These subjects may or may not have been the same ones with noted ACL pathology. The concentrations of 20 biomarkers were determined using a multiplex magnetic bead immunoassay. Biomarker concentrations were then compared between the 3 study groups (ACL tears with and without cartilage injury, and uninjured contralateral knees) using an analysis of variance test with pairwise comparisons. The minimal clinically important difference was calculated based on the standard error of measurement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The study included synovial fluid samples from 134 knees: 34 ACL tears without cartilage injury (mean age 34.0\u00a0years), 28 ACL tears with cartilage injury (mean age 36.3\u00a0years), and 72 healthy controls (mean age 41.1\u00a0years).
