Minimally invasive hip arthroplasty uses special tools and minimally invasive access technology, requiring only a small incision of 6-8 centimeters and well-protecting the integrity of the posterior muscle tissue and joint capsule, resulting in less intraoperative bleeding, better postoperative stability, and minimizing the probability of dislocation. It enables the patient to be allowed to freely turn over and lie on his side, squat and put on shoes and socks early after surgery, and other movements that are the early advances of traditional surgery, fully reflecting the advantages of minimally invasive surgery with less trauma, less pain and faster recovery.
