The dog had a plantigrade stance (Figure 2) and major lameness.
Preoperative ultrasound of a canine patient with acute Achilles tendon avulsion. The black line shows bone tearing at enthesis. Distance between two white crosses shows an abnormally wide thickness of the tendon at the level of rupture.

Ultrasound revealed a tendon avulsion with significant desmitis, tendon thickening, and bone tearing at the enthesis (Figure 3).
Immediate postoperative lateral (a) and frontal (b) conventional radiography of a canine patient after repair of an acute Achilles tendon avulsion. The interference screw is perfectly positioned. The profile view (a) shows the axis of the bone tunnel outlet at the proximal level of the calcaneus and screw located at the midheight of calcaneus, proximally and caudally to the talocrural joint. The frontal view (b) shows a bicortical characteristic of the interference screw at the level of implantation in calcaneus.

Eight-week postoperative conventional lateral radiography of a feline patient after repair of a patellar tendon rupture, showing the axis of the bone tunnel outlet at the caudal level of tibia and the level of implantation of the interference screw in the tibial crest through metaphysis (almost closed). Note the satisfactory implant position, without enlargement of the bone tunnel at the entry point of the interference screw. Radiolucency at the tip of the screw revealed slight distal displacement, considered as not significant.

Eight-week postoperative lateral conventional radiography of a canine patient after repair of the chronic avulsion fracture of the triceps tendon, showing the position of the interference screw. The image confirms comminuted avulsion fracture of the olecranon.

There was no change in the implant position on elbow radiography (Figure 6).
Ten-week postoperative ultrasound of a canine patient after repair of the chronic avulsion fracture of the triceps. The black line shows tendon and implant thickness, revealing good tendon healing and the absence of edema.
