Patient-Matched Technology Shows Value for Patients, Surgeons and the Healthcare System

MEMPHIS, Tenn., Jan. 11, 2012 /PRNewswire/ -- Smith & Nephew (NYSE: SNN, LSE: SN) today announces the publication of a new study on the value of patient-matched technology for total knee replacement. Published in the Journal of Arthroplasty (JOA), the official Journal of the American Association of Hip and Knee Surgeons, this first-of-its-kind study specifically looked at the VISIONAIRE patient-matched system from Smith & Nephew.

With the VISIONAIRE system, a surgeon uploads each patient's specific MRI and X-Ray images into Smith & Nephew's proprietary web-based software. A Smith & Nephew engineer then uses this data to design and build customized surgical instruments that accommodate the unique shapes and angles of each patient's joint for a more precisely aligned implant. 

According to the JOA study, surgeries that used patient-matched instruments resulted in implants that were a full degree closer to neutral – the body's natural alignment – than those using traditional instrumentation. The accurate placement of an implant has been shown to reduce implant wear and improve the longevity of an implant.[i]

Additional key findings in the study are that patient-matched technology:
  • Reduces the amount of time a patient spent under anaesthesia;
  • Shortens a patient's hospital stay;
  • Shortens the length of the incision required for knee replacement surgery.
Also, because patient-matched technology reduces the number of instrument trays required by 43% and eliminates more than 20 surgical steps for each surgery[ii], it may reduce hospital expenses related to total knee replacements by cutting sterilization costs and increasing OR efficiency.

I’m impressed, I must say. Really rarely do I encounter a blog that’s both educative and entertaining, and let me tell you, you have hit the nail on the head. Your idea is outstanding; the issue is something that not enough people are speaking intelligently about. I am very happy that I stumbled across this in my search for something relating to this.
