Fig 5. Synovial fluid/serum C-reactive protein (CRP) ratio in stifle joints of dogs with stable partial cruciate ligament rupture (CR) before and after treatment with bone marrow-derived mesenchymal stem cell treatment.

At diagnosis, synovial fluid/serum CRP ratio was elevated in the partial CR stifles of dogs that developed a second CR (n = 3) within the study period, when compared with the dogs that did not develop a second CR (n = 8). Synovial CRP was not measured in one dog because of insufficient sample volume. Synovial fluid/serum CRP ratio values were higher at 8 weeks in the dogs that did not experience CR within the study period.
