Brief summary
This observational study seeks to identify and validate novel soluble biomarkers (within blood, synovial fluid, urine) which contribute to the prognostic assessment of an individual with an acute knee injury, a group of individuals in which \ 50% will progress to symptomatic radiographic knee osteoarthritis (OA). 150 individuals will be followed over 5 years with clinical assessment including validated questionnaires, biological sampling and radiological imaging (X ray, magnetic resonance imaging (MRI)).
