Radiographic signs of stifle arthritis and synovial effusion in dogs with unilateral cranial cruciate ligament rupture after surgical stabilization and hyaluronic acid/doxycycline treatment.

Data represent median (range). Diagnosis, n = 16; 12 weeks after surgery, n = 15; 1 year after surgery, n = 8. NS – not significant (p>0.05). Changes in composite score and synovial effusion were not significantly different over time. One dog was excluded from the analysis at the 10 week recheck, because of development of contralateral CCLR at 67 days after surgery, 5 dogs were excluded at long-term follow-up.
