MicroPort® Orthopedics Completes First Evolution™ Total Knee Replacement in Jinhua City

Jinhua, China – Recently, a surgery using MicroPort^® Orthopedics' second-generation total knee replacement system Evolution™ Medial-Pivot Knee System ("Evolution™") was completed in a hospital in Jinhua of Zhejiang Province, which marked the first implantation of Evolution™ in Jinhua.

The female patient, 56, has been suffering from osteoarthritis in both knees for three years with stiffness. She received the total knee replacement with Evolution™. The surgery lasted for one hour and the patient had less blood loss during it. After the surgery, the patient recovered from restricted movement in her legs and is performing postoperative rehabilitation. The surgeon who performed the surgery said that compared to traditional knee prosthesis Evolution™ provides better post-operative experience as its unique design facilitates faster return to function. The surgeon was satisfied with the operative outcome and the performance of Evolution™, and he expressed interest in continuing using Evolution™ in the future. He also spoke highly of MicroPort^® Orthopedics' instrument for their outstanding performance.

As the second-generation medial pivot knee, 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, which 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 up stairs, kneel, and sit on heels. In this way, the system answers the traditional implant limitations to better balance stability and mobility. In the case of Jinhua, Evolution™ not only relived the patient from knee pain but also gives her better experience in daily activities, and thereby increases patient satisfaction.

As one of the well-known knee systems in the world, the 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 Jinhua means MicroPort^® Orthopedics will further expand the China market, to provide better orthopedic products and innovative solutions for surgeons and patients.
