Data from a study published online in The American Journal of Sports Medicine suggest that synovial fluid profile may help predict articular cartilage degeneration following anterior cruciate ligament (ACL) repair. 

The authors conducted a longitudinal cohort study of 26 patients who underwent ACL repair at a mean 8.5 weeks after injury and who had synovial fluid aspirated at the time of surgery. They found that higher synovial fluid sulfated glycosaminoglycan concentrations at the time of surgery were associated with worse cartilage composition during the first 3 years after surgery, based on T1ρ and T2 quantitative magnetic resonance imaging.
