Few reports have described avulsions of the medial or lateral heads, as well as bilateral avulsion of the origins of the gastrocnemius muscle in dogs and cats. The objective of this study was to describe the first report of avulsion of the origins of the lateral and medial gastrocnemius muscle in a cat (Felis catus), as well as the surgical reinsertion technique. A mixed breed queen at 10 years of age presented claudication of the right hind limb with plantigrade stance. Bilateral avulsion of the heads of the gastrocnemius muscle was diagnosed based on findings from clinical a examination. The reinsertion technique was performed with monofilament nylon thread in a modified Kessler suture anchored in a hole created in the distal metaphyseal portion of the femur, obtaining satisfactory recovery after a period of additional external immobilization followed by physical therapy.
