Domestic cat, 8 months old, male, weighing 3.9 kg. Due to hip dysplasia with subluxation and severe limping, it was decided to perform hip replacement surgery. Preoperatively, the BaiLu iBlueVet software was used for precise surgical planning, and intraoperatively, the BaiLu Micro & Nano bone cement bionic hip joint system was used for the replacement. A 9-month follow-up after the BaiLu Micro bionic cemented THR shows from X-rays that the cat's leg muscles have recovered to full and symmetric condition, with excellent bone ingrowth! This black cat's quality of life has significantly improved postoperatively, allowing it to regain its greatest joy—climbing trees (the video shows it moving freely and walking nimbly). The cat’s ability to return to its favorite high-difficulty activity is the strongest evidence of the surgery’s success!BlueSAO BaiLu Hip Replacement System: the mainstream forged stem technique used in human medicine, not a 3D-printed stem!
