Smith & Nephew's computer-assisted surgery system to allow precise knee implants

Memphis 24 August 2005Smith & Nephew Orthopaedics have launched AchieveCAS for computer-assisted knee implant surgery. AchieveCAS is a computer system with custom-designed software, infrared camera and surgical instruments. The system is designed to allow the surgeon to navigate a total knee during surgery, allowing surgeons to more precisely place implants, particularly within smaller incisions, through enhanced guidance and visualization. AchieveCAS is already available for hip implants.


Computer-assisted surgery (CAS) is a critical advancement in orthopaedic surgery, providing surgeons with real-time data and greater precision with which to align orthopaedic implants. CAS also offers significant benefits to the patient, reducing surgical exposure and recovery times, enabling patients to more quickly resume normal activities.

This launch is part of a five-year exclusive business relationship between Smith & Nephew and ORTHOsoft Inc. a company specializing in software development for computer-assisted surgery. "We are pleased with this arrangement and the technology it brings surgeons and their patients", stated Scott Flora, senior vice president and general manager of Smith & Nephew Reconstructive Division. "AchieveCAS is the most compact and most user-friendly orthopaedic computer-assisted surgery system available."

AchieveCAS has all computer and touch screen functions self-contained in a small unit that sits neatly with its camera on a thin metal stand, thereby occupying little space in an operating room. It also features a "touchless" capability allowing the surgeon to operate the computer directly from the sterile field. The system allows for the more accurate alignment and placement of a Smith & Nephew implant and may extend the implant's lifespan by reducing uneven wear, thus preventing future corrective surgeries. In addition, precise implant placement may help reduce the risk of post-operative dislocation and contributes to long-term implant stability and increased range of motion.

"AchieveCAS is a great system. With the systems' enhanced guidance and visualization capabilities I am able to more precisely implant the knee during minimally invasive surgery", stated Dr. Robert Thornberry, an orthopaedic surgeon in Tallahassee, Florida.
