Abstract Tendon rupture is an uncommon cause of lameness in small ruminants. This report aimed to present a successful common calcaneal tendon (CCT) tenorrhaphy in a Dorper lamb after rupture during a tail docking procedure. The lamb presented a 3.5 cm linear open wound over CCT. During surgery, an incision was made over the skin on the caudolateral aspect of the distal tibia over CCT. The tendon stumps were isolated using haemostats, repair was performed via a locking‐loop suture pattern using non‐absorbable suture material. Postoperative limb immobilisation was conducted using a full‐limb compressive bandage and a modified Schroeder–Thomas splint, and follow‐up continued for 4 weeks. Ten months postsurgery, a fibrous callus was evident and the lamb exhibited no lameness. In this report, CCT tenorrhaphy using non‐absorbable suture in a locking‐loop pattern was a successful approach. Limb immobilisation in extension and specific physiotherapy are important methods to fasten the patient's rehabilitation.
