A comparative study of using Kessler Suture Pattern versus Polypropylene meshes implantation to repair Tenotomized Achilles tendon in bucks

The aim of the current study was to compare the efficacy of Kessler suture pattern and polypropylene meshes implantation to repair severed Achilles tendons in bucks. For this purpos 16 local adult bucks, weighing 30-35kg were used and equally distributed into two groups, the first group: (control group) and the second group (mesh group). Animals were sedated with xylazine 2% and anesthetized locally with lidocaine hydrochloride 2% infiltrated subcutaneously. Skin incision approximately 5 cm. in length was made over the Achilles tendon. The tendon was isolated by blunt dissection from the underlying tissue, then the left Achilles tendon was transected in its mid portion. In the control group, tenorrhaphy of Achilles tendons were immediately performed by using Kessler suture technique using (polypropylene No. 1). In the second group, a polypropylene mesh was wrapped around the cut ends and fixed to the tendon by simple interrupted stitches of polypropylene thread (No.1). Then skin was sutured by interrupted horizontal mattress using silk No.1. Finally plaster of Paris with window was applied. The skin stitches were removed after 10 days. The clinical signs of all animals showed severe lameness during the first three weeks with no significant differences between the two groups. Lameness reflected significant differences (P
