Effect of Arthroscopic Lavage on Systemic and Synovial Fluid Serum Amyloid A in Healthy Horses.
Abstract: To evaluate the effect of arthroscopic lavage on systemic serum amyloid A (SAA) and SAA, total protein, nucleated cell count, and percentage of neutrophils in synovial fluid in healthy horses. Methods: Prospective experimental study. Methods: Healthy adult horses (n = 6). Methods: Middle carpal joints were randomly assigned to 1 of 2 treatments: arthrocentesis (controls) or arthroscopic lavage, with 30 day washout period between treatments. Synovial fluid and blood samples were collected at 0, 24, 48, 72, 96, and 120 hours. Measurements included systemic and synovial fluid SAA, as well as total protein, nucleated cell count, and percentages of neutrophils in synovial fluid. Data were analyzed by median quantile regression and Wilcoxon signed-rank test and significance level set at P < .05. Results: Systemic and synovial fluid SAA did not increase from baseline (except systemic SAA at 24 hours for both treatments) and were not significantly different between treatments. Total protein values were significantly increased after arthroscopic lavage (except at 96 hours) but not in controls at all time points. With both treatments, nucleated cell counts significantly increased from baseline values at all time points. Percentages of neutrophils were significantly increased after arthroscopic lavage at all time points, but only at 24 hours in controls. Conclusions: Total protein, nucleated cell count, and percentage of neutrophils in synovial fluid were significantly increased after arthroscopic lavage; however, synovial fluid SAA was not affected by this procedure. Further research is warranted to validate synovial fluid SAA as a monitoring tool during treatment of septic arthritis.

The study investigates the impact of arthroscopic lavage, a surgical procedure usually used for the treatment of arthritis, on systemic and synovial fluid Serum Amyloid A (SAA) in healthy horses, as well as other factors such as total protein and neutrophil percentages.
Study Design and Methodology
- The study was a prospective experiment involving healthy adult horses. The middle carpal joints of these horses were subjected to two treatments: arthrocentesis (which served as a control) or arthroscopic lavage.
- A washout period of thirty days was permitted between treatments to ensure any effects of the first treatment had worn off before the second treatment was administered.
- Researchers collected blood and synovial fluid samples from the horses at intervals – 0, 24, 48, 72, 96, and 120 hours – after each treatment. They then measured the levels of systemic and synovial fluid SAA, total protein, nucleated cell count, and percentages of neutrophils present in the synovial fluid of the horses.
Results
- The levels of systemic and synovial fluid SAA did not increase from the base value (except at 24 hours post-treatments).
- The protein levels in the synovial fluid of the horses were noticeably higher following arthroscopic lavage at all time points, except 96 hours.
- The count of nucleated cells rose significantly from the baseline values at all times following both treatments.
- There was a significant rise in the percentage of neutrophils post-arthroscopic lavage at all-time points. For the control group (arthrocentesis), this increase was only observed at 24 hours.
Conclusions
- The increase in total protein, nucleated cell count, and percentage of neutrophils post-arthroscopic lavage indicates the procedure does have a significant impact on these factors in a horse’s synovial fluid.
- However, this surgical procedure did not significantly affect synovial fluid SAA values.
- These findings propose further studies to confirm whether synovial fluid SAA can be effectively monitored during septic arthritis treatment.
