Arthroscopic Biceps Tenodesis: Technique and Results in Six Dogs
Biceps tenodesis was performed using an arthroscopic-assisted technique on six dogs diagnosed with chronic bicipital tendon pathology. The technique was performed using two different fixation methods (i.e., cannulated interference screw, cannulated screw and tissue washer). All six dogs had successful outcomes in terms of return to full function at a mean follow-up time of 11.7 months after surgery. Arthroscopic biceps tenodesis is a feasible option for surgical management of biceps tendon pathology, and it may have advantages over open tenodesis and open or arthroscopic tenotomy. Further study is needed before definitive recommendations regarding indications, complications, and prognosis associated with arthroscopic biceps tenodesis can be made.

Arthroscopic view of a biceps tendon of a dog from a caudolateral camera portal. Suture (0 polypropylene) has been passed through the tendon to allow for manipulation of the tendon during tenodesis.
Arthroscopic views of a biceps tendon of a dog from a caudolateral camera portal. The tendon is being transected at its origin using a basket forceps (A), causing complete detachment and distal retraction (B). The polypropylene suture is seen attached to the retracted tendon in 3B.
