Correlations between clinical characteristics and cytokine levels in the synovial fluid of adolescents. Growth plate maturity and diagnosis are reported in Table 1. Lysholm score was calculated as described in Methods. Time elapsed between trauma and sample collection was considered as follows: acute: 0–48 h after injury; subacute: 3 days–3 months; chronic group: >3 months.
