First Evolution™ Total Knee Replacement Completed in Heilongjiang Province

Heilongjiang, China – On December 19, a surgery using MicroPort® Orthopedics' second-generation total knee replacement system Evolution™ Medial-Pivot Knee System ("Evolution™") was completed in the First Affiliated Hospital of Harbin Medical University of Heilongjiang Province, which marked the first implantation of Evolution™ in Heilongjiang.
The female patient, 59, suffered from osteoarthritis in her right knee. The surgery was performed by Professor Weiliang Yang who finished the prosthesis fitting in 30 minutes. Professor Yang spoke highly of Evolution™'s stable performance and its sizing profile. He also noted, its matching tools are easy to use and provide great help for surgeons during the operation. Professor Yang said he looks forward to seeing Evolution™ benefit more Chinese patients.
Postoperative stability is an important indicator to determine the outcome of a knee replacement surgery as well as the patient's motion and experience after the surgery. Evolution™ features medial pivot design, ball-in-socket articulation, and slideway in lateral side, which enhances stability and allows the prosthesis to move and feel more like a normal knee. Evolution™ aims to provide an implant that delivers low bone cut, wear limiting design, flexion stability, and high patient satisfaction. In addition, it facilitates faster return to function as it protects the muscle strength of quadriceps femoris.
As the second-generation medial pivot knee of MicroPort® Orthopedics, Evolution™ imitates the natural motion of the knee by incorporating a patented ball-in-socket feature on the medial side, which enhances stability and allows the prosthesis to move and feel more like a normal knee. Such design is in line with the latest development trend of knee prosthesis. At the same time, Evolution™ provides better flexion to meet the needs of daily life for most Asian patients, making it easier for them to go upstairs, kneel, and sit on heels. In this way, the system answers the traditional implant limitations to better balance stability and mobility.
As one of the well-known knee systems in the world, Evolution™ has gained high market recognition after launched in the US in 2010 and subsequently sold to Europe and Japan. It entered the Chinese mainland market and Hong Kong market in 2015. The completion of the first case in Heilongjiang Province means MicroPort® Orthopedics will further expand the China market to provide better orthopedic products and innovative solutions for surgeons and patients.
