New SIGMA® High Performance Revision Instruments Focus on Increasing Operating Room Efficiency

WARSAW, IN – (OCTOBER 18, 2012) – DePuy Orthopaedics, Inc., a global leader in devices for joint replacement, today announced the launch of a new line of instrumentation for its SIGMA® Revision Knee Portfolio that focuses on increasing operating room efficiency. The SIGMA High Performance (HP) Revision Instruments are designed for use with DePuy’s SIGMA Knee implants, which provide a comprehensive range of implant options to address even the most complex revisions.

The HP Revision Instruments reduce the average number of instrument cases required during surgery by 40 percent versus leading competitive systems, combined with a 70 percent reduction in tibial prep steps versus other systems.1 The system also incorporates visual cues and easy adjustments on the cutting blocks and a new simplified trialing system to allow surgeons to increase efficiency throughout the procedure.

“The number of sets and trays traditionally needed for revision knee procedures can lead to inefficiency and additional costs in the operating room,” said Andrew Ekdahl, Worldwide President, DePuy Orthopaedics, Inc. “Reducing the number of instrument cases by nearly half and the number of steps required to prep the tibia by 70 percent could lead to a more efficient surgery—and that’s better for the patient and better for the healthcare system.”1

The HP Revision Instruments work with two unique technologies from DePuy that address the top reasons for revision knee failure--loosening and instability--through two differentiated technologies: the SIGMA Rotating Platform Knee and Metaphyseal Sleeves.

  • Rotating Platform: DePuy offers the only revision knee portfolio with a mobile bearing option for every constraint level.  Revision knees utilizing rotating platform technology diffuse shear and torsional forces typically produced at the implant bone interface.
  • Metaphyseal Sleeves: Unique stepped sleeves are designed to compensate for substantial type 2 and 3 cavitary defects, while bringing the implant into contact with strong, supportive bone. The sleeve is stepped to compressively load the bone and form a strong foundation for reliable implant stability, avoiding excessive bone resection and restoring the joint line.

“The future predicts a substantial growth in the need for arthroplasty, placing an increasing burden on both general orthopedists and arthroplasty surgeons to manage these patients,” said Aaron Altenburg, MD, of Altenburg Orthopedics and Total Joint Surgery in Pocatello, ID. “With continued economic and performance pressures, success will inevitably  depend on collaborative efforts between surgeons, hospitals and industry to increase efficiency and curb costs while still maintaining the highest levels of care.”
