Secondary
Shoulder
According to a company press release, the Global Unite Platform Shoulder System now has anatomic components which “enables surgeons to use the same humeral stem to repair shoulder fractures or perform a total (anatomic) shoulder replacement. For patients later needing a reverse total replacement, surgeons are able to covert the already-implanted humeral stem to a total reverse construct without the use of a stack-on adaptor. The use of a stack-on adaptor may overstuff the joint and limit the patient’s range of motion.”
Hip
“The Corail Revision Hip System is designed to treat patients in need of hip revisions who have mild to moderate femoral defects, ” according to the press release The company states that the Corail is the first and only tapered wedge revision stem in the U.S. Should patients need additional revision surgery in the future, the system has a bone-preserving design. The company says that an additional benefit is that the Corail stem requires the same number of instruments as the primary stem. Normally, more instruments are required for a revision surgery than the primary surgery.
Knee
The company also introduced the Trumatch Resection Guide for its recently released Attune Rotating Platform knee. A resection guide and pin guide are also available for the Attune fixed knee.
Per the press release, “Trumatch Personalized Solutions is a surgical instrumentation system that aids in knee implant positioning and procedural efficiency. The system utilizes as few as two traditional trays in the operating room (compared to an average of 6-9 trays) and eliminates up to nine surgical steps, which can increase procedural efficiency.”
DePuy Synthes introduced the Attune knee system a year ago and implanting more than 31, 000 of the devices during that time. Zimmer Holdings, Inc. also introduced a new knee, the Persona, a year ago.
The last two significant knee system launches before that were Biomet Inc.’s Vanguard and Stryker Corporation’s Triathlon in 2004.

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
