Objective: The goal of this study was to establish the utility of serum Cartilage Oligomeric Matrix Protein (sCOMP) as a biomarker for differentiating between disease severity grades of knee osteoarthritis (KOA).

Material and Method: Patients of osteoarthritis of knee were included as Cases (100 subjects) and normal adults were taken as Controls (50 subjects). Clinical, radiological and biochemical assessment was done by WOMAC score, knee radiograph and blood sample for sCOMP respectively.

Results: Results show WOMAC Score was significantly higher in cases (49.97 ± 17.98) than in Controls (11.24 ± 06.07) (p < 0.001). Mean sCOMP level was significantly higher in Case group than in Control group (17.38 ± 4.99 U/L vs 1.16 ± 0.39 U/L; p = 0.001). sCOMP increases with increasing K-L grades except in grade III. In Case group sCOMP was 14.60 ± 6.47 U/L in K-L grade I; as 17.47 ± 4.99 U/L in K-L grade II; as 17.25 ± 4.63 U/L in K-L grade III and as 19.77 ± 4.65 U/L in K-L grade IV. One-way ANOVA of K-L Grade with sCOMP (F = 1.55, p = 0.02) and with WOMAC score (F = 20.18, p = 0.001) show significant association. Pearson Correlation and coefficient (r) value show that Age has moderate positive and significant co-relation with WOMAC Score (r = 0.43, p = 0.001), with KL grade (r = 0.40, p = 0.001) and weak positive and significant co-relation with sCOMP level (r = 0.24, p = 0.01).

Interpretation and Conclusion: The receiver operative curve (ROC) analysis suggested a “Cut-off” value of sCOMP as 9.06 U/L (Sensitivity 99%; Specificity100%; Accuracy100%) between Control group and Case group with excellent discriminatory power (p = 0.001) but not for various subgroups of disease severity of KOA.
