Early diagnosis of knee osteoarthritis (OA) remains a diagnostic challenge.
Urinary C-terminal crosslinked telopeptide of type II collagen (urinary CTX-II) is one of the potential OA biomarkers.
Arunrukthavon et al1., study published at Arthroplasty in 2020 concluded that
- Patients with knee OA had higher urinary CTX-II levels than healthy controls (Figure).
- Levels of urinary CTX-II were independently correlated with radiographic severity of knee OA.
- Age, gender, and patient-reported outcomes exerted no effect on the urinary CTX-II levels.
Comparison of the levels of urinary CTX-II between knee OA patients and controls:
