Tarsocrural Arthroscopy for Osteochondrosis Dissecans: Clinical Features of a Referral Hospital Population and Prevalence of Abnormalities within the Plantar Pouch

Reasons for performing study There is limited information on tarsocrural arthroscopy for osteochondrosis dissecans lesions (OCD) in Great Britain, and routine examination of the plantar pouch has not been described. Objectives To describe clinical features of cases undergoing tarsocrural arthroscopy for OCD and estimate the prevalence of abnormalities within the plantar pouch. Study design Retrospective case review. Methods Case records of all horses that had tarsocrural arthroscopy for OCD at Rossdales Equine Hospital between 1 January 2005 and 31 December 2013 were included (n = 99). Descriptive data and 95% confidence intervals (CI) were constructed in Microsoft Excel. Results Warmbloods/Warmblood‐crosses were significantly over‐represented compared to the normal hospital population, comprising 42.4% (CI 32.7–52.2%) of the study (P
