Official Title: Use of a Marker for Cartilage Damage to Differentiate the Diagnosis of Femural Acetabular Impingement From Extraarticular Pathologies.
Brief Summary:
The diagnostic gold standard to differentiate FAI (femural acetabular impingement) from other muscular-tendinous pathologies is, actually, the injection of intra-articular anesthetic (lidocaine), with a pre- and post- evaluation of pain scale.
If, after injection, the pain disappears, the pain is probably due to an articular problem (FAI). This kind of differential diagnosis test has a sensibility of 100% and a specificity of 81%.
C-terminal telopeptide of type II collagen (CTXII) as cartilage degradation index, could be a marker, simply detectable, to assess the healthy of the cartilage status and could be measured in serum and urine.
