The purpose of this study was the experimental evaluation of the arthroscopic brachial bíceps tenotomy in dogs cadavers using needle, n° 15 scalpel blade and radiofrequency scalpel. The arthroscopic and instrumental portals were performed caudal and cranial to the acromial process, respectively. When necessary, an accessory instrumental portal, cranial and near the intertubercular groove was used too. Better sectional time and quality of the seccioned edges were showed by the radiofrequency scalpel and the n° 15 scalpel blade than the hypodermic needle. The break of the blade scalpel inside one joint was the main complication that occurred during the section tendon procedure. It was difficult to see the transition between the supraglenoidal tubercle and the tendon due the presence of sinovial hyperplasia. In this research there was a dificulty to cut a structure as a plica in the end of the procedure in all groups, which have not been described before. In conclusion the lateral and caudal arthroscopic and lateral and cranial instrumental portals were satisfactory for the arthroscopic brachial biceps tenotomy when the n° 15 scalpel blade and radiofrequency scalpel were used.
