Tianjin, China – From September 1 to September 3, MicroPort® Orthopedics attended the 2017 Annual Congress of Chinese Arthroplasty Society ("CAS2017") in Tianjin and hosted a satellite meeting about knee prosthesis. The congress was hosted by Chinese Association of Orthopedic Surgeons, and co-organized by Tianjin Hospital of Tianjin University and Tianjin Medical Association. It contains seven sessions covering topics such as hip, knee and fast recovery, and gathered nearly a thousand of domestic orthopedic surgeons to exchange ideas on the latest advancement, technology innovation and clinical application of the orthopedic industry in forms of lectures, discussion and debate.
During the knee session, MicroPort® Orthopedics held a satellite meeting themed on "patient satisfaction – how knee prosthesis impacts the postoperative effect," which attracted wide attention from experts in attendance. Professor Yixin Zhou of Peking University Orthopedic Department and Beijing Jishuitan Hospital was invited as the lecturer to present on how the medial pivot knee achieves flexion stability and wear-limiting design.
Professor Yixin Zhou started his lecture with several pictures of worn hip prosthesis. He said, according to his research findings of hip replacement failures, hip prosthesis wear is probably caused by the instability resulting from the mismatching of femur head and acetabulum interface. Such findings triggered two questions: what determines the patient satisfaction of a knee replacement surgery and what factors make the knee flexion? The answer is clear: the two key factors to determine patient satisfaction are soft-tissue balancing, which largely relies on the surgeon's technique, and prosthesis design, which plays an important role in post-operative stability.
Afterwards, Professor Yixin Zhou listed some traditional knee prosthesis designs which have good survivorship but limitations in restoring knee function. MicroPort® Orthopedics launched the first-generation medial pivot knee in 1998 with around 20 years' clinical history in the US market. In 2010, the second-generation EVOLUTION® Medial Pivot Knee System ("EVOLUTION®") was launched, which features high-matching ball-in-socket articulation to enhance stability and allow the prosthesis to move and feel more like a normal knee, so as to enhance stability and comfort for patients in their daily life.
EVOLUTION® was built on around 20 years of excellent clinical history of the first-generation ADVANCE® Medial-Pivot Knee System ("ADVANCE®"), with more prosthesis systems to choose from, which offers ideal solutions to patients with orthopedic diseases. EVOLUTION® was officially launched in the China market in 2015 and has been carried out clinical applications in several domestic hospitals. President of MicroPort® Orthopedics China Zixin Weng said:" It has become the main focus of the joint prosthesis field on how to improve function and drive patient satisfaction. With its excellent clinical performance, EVOLUTION® has won high recognition from experts in the joint surgery field. We will further promote the use of EVOLUTION® in China to promote the development of China's joint surgery industry and benefit more patients."
