SALT LAKE CITY, UT [March 2, 2026] Total Joint Orthopedics, Inc. (TJO), an innovator in joint replacement solutions, today announced it has surpassed 50,000 total implants placed nationwide, including more than 38,000 Klassic® Knee implants.
In 2025, 32% of TJO procedures were performed in ambulatory surgery centers (ASCs), reflecting sustained surgeon adoption in environments where operational efficiency and procedural consistency are essential.
As joint replacement expands across sites of care and economic pressures intensify, surgeons are prioritizing systems that reduce complexity without compromising outcomes. And particularly in ambulatory environments, efficiency is operational: fewer trays and simplified workflows directly impact setup, sterilization demands, and turnover time.
TJO’s portfolio is built around an “Efficiency by Design” philosophy that prioritizes streamlined instrumentation, system consistency, and adaptability across hospital and ASC settings, without any compromise in survivorship or functional outcomes.
“The shift to ambulatory joint replacement isn’t slowing down, and the systems that win in ASCs won’t be the ones with the most trays – they’ll be the ones that enable surgical teams to maximize efficiency while achieving excellent patient outcomes. That’s what we’ve engineered from the beginning, and 50,000 procedures in, surgeons are proving it every day.” – Erin Hofmann.
“Ambulatory surgery centers are now our fastest-growing primary TKA setting,” comments Erin Hofmann, TJO’s CEO. “In those environments, efficiency is operational. Systems that simplify workflow and reduce tray burden earn their place in the OR. Surgeons stay with solutions that make their teams’ jobs easier while maintaining excellent outcomes.”
Of the 50,000 implants, more than 38,000 have been knee procedures, driven by adoption of the Klassic® Knee System and the Klassic® Revision Knee System across hospital and ambulatory environments.
The Klassic® Knee System features the only modern universal femoral component on the market; a design that eliminates the need for left and right implants. This symmetric architecture enables streamlined instrumentation, reducing sterilization and storage burden while supporting faster setup and turnover times in high-volume ASC environments. Through the Klassic ONE® single-tray system, up to 90% of primary total knee procedures can be performed with a single instrument tray—delivering estimated per-case cost savings of up to $1,3503-5.
Ten-year clinical data on the Klassic® Knee demonstrates no compromise in survivorship or functional outcomes.1 In a comparative analysis, patient outcomes were similar across implant types, while the symmetric group demonstrated significantly improved radiographic patellar tracking, reinforcing the durability of the design philosophy.2

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.
