Hi , just wanting to know if any one has had success with investigative orthoscope on front elbow of small dogs to see why they have constant limp ( its usually a large dog problem ) we have a 1 1/2 year Boston old whose had x-rays that didn,t show anything and now have been advised to do the orthoscope procedure to see whats happening in the elbow ,its been a on and off problem for months now, shes had courses of cartrophen and is on sashas blend etc but wondering if anyone has any info this, if their dogs after this procedure (depending what they find i guess too ) still limped or had arthritis symptoms .
