Standardised Tendon Fenestration with ITEC-Technique for Lateral Epicondylosis with Injection of Betamethasone versus Autologous Blood.

Infiltration is one of the treatment options for lateral epicondylosis, a degenerative process in the tendon of the musculus extensor carpi radialis brevis. The aim of this study was to evaluate the clinical outcome of a standardised fenestration technique, the Instant Tennis Elbow Cure (ITEC) technique, with injection of betamethasone versus autologous blood. A prospective comparative study was performed.
