Sigma® High Performance Partial Knee

Jack Farr, M.D., will perform a bi-compartmental knee replacement with the Sigma® High Performance Partial Knee. During this procedure, Dr. Farr will replace the medial and patellofemoral compartments of the knee. The broadcast will be moderated by David Fisher, M.D.

"Bi-compartmental arthroplasty as opposed to total knee arthroplasty is a resurfacing concept, where we are trying to put the surfaces of the components where the articular surfaces were of the knee," explains Dr. Farr. "We retain both cruciate ligaments, hopefully adapting the knee to more natural kinematics as opposed to a total knee replacement." The live surgery will be performed at the Indiana Orthopaedic Hospital in Indianapolis, Indiana. As one of the designing surgeons for the High Performance Partial Knee, Dr. Farr has been instrumental in surgeon education with this new product offering. DePuy Orthopaedics, Inc., a company that has taken a leading role in educating surgeons, is making the broadcast available for free via

Sigma High Performance Partial Knee for early knee intervention For early intervention, the Sigma High Performance Partial Knee System is the only partial knee solution on the market that can replace the medial, lateral and/or patellofemoral compartments while providing low wear and up to 155 degrees of flexion. The tibial implants utilize a moderately cross-linked, oxidatively stable polyethylene.

"This is a truly patient and knee specific system that can work across the continuum of early interventional care," said Dr. Farr. "The System has individual compartment components that were designed specifically to work independently or together to give the surgeon flexibility during surgery and in subsequent surgeries depending on disease progression."

Important Safety Information
As with any medical treatment, individual results may vary. Only an orthopaedic surgeon can determine whether an orthopaedic implant is an appropriate course of treatment. There are potential risks, and recovery takes time. The performance of the new joint depends on weight, activity level, age and other factors.
