Abstract

A 5-year-old castrated male Chihuahua weighing 1.54 kg was examined because of a several month history of progressive right hind limb lameness. Physical examination of the stifle joints revealed pain and a grade IV medial patellar luxation on the right stifle joint. The right and left stifle joints were associated with a lameness of grade 2 and grade 0, respectively. Radiography revealed osteophytes or subchondral cystic lesions on the right and left stifle joints. Osteoarthrosis (OA) scores for the right and left stifle joints were 20 and 12 respectively. Combination of surgery and implantation of autologous adipose tissue derived mesenchymal stem cells (aAT-MSCs) was determined with informed consent. $1{\times}10^6$ aAT-MSCs suspended in PBS and 0.6 mL of hyaluronic acid were injected in the right stifle joint postoperatively. Osteoarthrosis scores and the lameness grade for the right and left stifle joints were 19 and 13, and 0 and 0 19 months after treatment, respectively, and 14 and 15, and 0 and 0 five years after treatment, respectively. This case report shows radiographical evidence of a decrease in osteophytes and subchondral cystic lesions on the stifle joint with OA after aAT-MSCs injection.

5년령 중성화된 수컷 치와와가 수개월간의 오른쪽 후지 파행 증상으로 내원하였다. 신체 검사에서 통증을 동반한 4등급의 슬개골 내측 탈구를 확인 하였고 오른쪽 왼쪽 후지 파행등급 2 와 0을 각각 확인 하였다. 일반 방사선 사진에서 골증식체와 연골하 병변을 확인 하였고 오른쪽과 왼쪽 후지 골관절증 점수 20 과 12를 각각 확인하였다. 슬개골 탈구 정복술과 자가지방 유래 줄기세포 치료를 보호자의 동의 하에 결정 하였다. $1{\times}10^6$ 개의 줄기세포를 PBS, 인공 괄절액과 함께 슬개골 탈구 정복술 후에 주입 하였다. 주입 후 19개월에 오른쪽 왼쪽 후지 파행등급 0 와 0, 골관절증 점수 19 와 13을 각각 확인 하였고, 5년후에 파행등급 0 와 0, 골관절증 점수 14 와 15를 각각 확인 하였다. 본 증례를 통해 자가지방 유래 줄기 세포치료를 받은 관절에서 골관절증이 감소 된 것을 확인 할 수 있었다.
