CTs were performed pre‐operatively and 6 months post‐operatively. CTOAM and SJSW measurements were acquired in 7 locations within the joint and compared to an age‐matched normal control group. Pearson correlation was performed on SJSW and CTOAM measurements. A linear mixed model determined the effect of disease and treatment on SJSW and CTOAM measurements.</p> </sec> <sec id="vsu12121-sec-0005" sec-type="section"> <title>Results</title> <p>Fifteen dogs (28 elbows) with FMCP participated (11 arthroscopic FMCP removal, 17 with additional PUO). Data were normally distributed. Pearson correlation between CTOAM and SJSW measurements showed moderate to strong negative correlation in the control dogs. Preoperatively, affected elbows had lower medial compartment and higher lateral coronoid process CTOAM values than normal elbows. After treatment, CTOAM values of the medial compartment increased to normal. Treatment with PUO did not affect SJSW or CTOAM.</p> </sec> <sec id="vsu12121-sec-0006" sec-type="section"> <title>Conclusions</title> <p>Our data agree with these previous studies suggesting lower subchondral plate mineralization in dogs affected by FMCP. Arthroscopy may result in higher CTOAM values secondary to increased loading.</p> </sec> </abstract>
