Figure 6. Time to contralateral cranial cruciate ligament rupture stratified by severity of synovial effusion or osteoarthritis in the contralateral stifle.

Figure 6

Kaplan-Meier plots for a population of 85 client-owned dogs. (A) Time to contralateral cranial cruciate ligament rupture was significantly decreased in dogs with Grade 2 radiographic synovial effusion of the contralateral stifle at diagnosis, when compared with the grades of 0 or 1 (p<0.001). (B) Time to contralateral cranial cruciate ligament rupture was significantly decreased in dogs with Grade 3 osteophytosis of the contralateral stifle at diagnosis, when compared with the grade 0 and grade 2 (p<0.05).
