A Labrador retriever, 2 yearsold, female, named Coco, neutered, 35kg. In early 2020, bilateral hip arthritis was diagnosed. At the beginning of December, there was a sudden limp and severe pain in the right hind limb. There was no cruciate ligament injury or other problems. We did THR surgery for right leg by using BlueSAO φ26mmcup，7# stem and φ16mm+6mm head. The surgery was performed jointly by Dr. Zhou Luoping and Dr. Wu Junjie at Shanghai PEACE UNION VETERINARY SERVICE on December 10, 2020.
