Wright Medical Group, Inc announced the launch of the EVOLUTION Medial- Pivot Knee System, representing Wright’s next generation in medial-pivot knees, according to a press release. It features enhanced instrumentation, more sizing options and a posterior stabilized option.
Wright said that these and other features of the new EVOLUTION Medial-Pivot Knee System will be demonstrated in the following surgery webcast events:
- Monday, August 2, 2010 – 5:00 p.m. CDT: Surgery by David DeBoer, MD, from St. Thomas Hospital in Nashville, Tenn. www.orlive.com/evolutionknee
- Monday, August 2, 2010 – 7:00 p.m. CDT: Surgery by Lowry Barnes, MD, from St. Vincent Hospital in Little Rock, Ark. www.stvincenthealth.com/webcast/
The new knee system builds upon 12 years of clinical experience with the ADVANCE Medial-Pivot Knee System. Wright’s medial-pivot technology is designed to replicate the stability and function of the natural knee. David Blaha, MD, of Ann Arbor, Mich. explained in the release, “The unique feature of both the ADVANCE and the EVOLUTION Medial Pivot knees is the ‘ball-in-socket mechanism’ on the medial side. The ‘ball-in-socket’ mechanism is designed to mimic the anatomy of the normal knee to promote more natural stability and motion.”
The company said that studies have shown that its medial-pivot technology has been consistently preferred by patients who received bilateral knee implants with a medial-pivot design in one knee and a traditionally-designed implant in the other knee and that the EVOLUTION Knee System was inspired by this patient preference.
Wright said it created the system to enhance its medial-pivot technology by offering more sizing options, improved instrumentation and a medial-pivoting posterior stabilized option. These enhancements were achieved through state-of-the-art engineering concepts and manufacturing technologies, including the use of CT-scans to produce implants which more accurately replicate natural knee anatomy, as well as features to aid in implantation through less-invasive surgical exposures. The resulting EVOLUTION Knee System is designed to ease rehabilitation and address stability concerns which may be experienced by some total knee replacement recipients.
Lowry Barnes, MD, of Little Rock, Ark. noted in the release, “Often, total knee replacement patients complain that their replaced knee does not feel normal, citing noises or a sensation of the joint slipping, especially as they descend stairs. The EVOLUTION implant’s more refined medial-pivot design may feel more normal for patients.”
