Tibial plateau leveling osteotomy in a cape clawless otter (Aonyx capensis) with cranial cruciate ligament ruptures

J Zoo Wildl Med. 2015 Mar;46(1):179-83. doi: 10.1638/2014-0162R1.1.

Abstract

A 13-yr-old female Cape clawless otter (Aonyx capensis) presented with an acute mild right pelvic limb lameness that progressed to a non-weight-bearing lameness. Diagnosis of a ruptured cranial cruciate ligament (CCL) was made based on positive cranial drawer during physical examination and was supported by radiographs. A surgical repair with a tibial plateau leveling osteotomy (TPLO) and bone anchor with an OrthoFiber suture was performed. The tibial plateau angle was reduced from 30 to 5 degrees. The otter returned to normal function after 12 wk of exercise restriction. Twelve months after surgery, the left CCL ruptured and a TPLO was performed. No complications developed after either surgery, and the otter had an excellent return to function. This is the first report of a cranial cruciate ligament rupture and TPLO procedure in a mustelid, supporting its application to noncanid and felid species.
