TJO Expands Klassic® Revision Knee to include infection management with the launch of Klassic® Infection Spacer System.

SALT LAKE CITY, November 3, 2026 — Total Joint Orthopedics, Inc. (TJO), a developer of hip and knee replacement systems, announces the launch of its Klassic® Infection Spacer System (KISS), expanding the Klassic® Revision Knee System for periprosthetic joint infection (PJI) revision procedures. This system is the first of its kind to be cleared for a dual indication: both permanent implantation and temporary implantation for PJI. Unlike traditional static or molded spacers constructed from cement, KISS features permanent implant materials (Aurum®/Ti, CoCr and ultra-high molecular-weight polyethylene). 

The System’s modularity, with expanded fixation and augmentation options, helps deliver a stable, functional knee that preserves range of motion, reduces pain, and provides a straightforward path to reconstruction. The Ultra-PS® articulating surface features an ultracongruent design that provides stability through the full range of motion after extensive debridement in many PJI cases. 

KISS leverages the efficiency of TJO’s Klassic ONE® System, requiring a single tray of instruments for up to 90% of cases. "Joint infection is among the most stressful issues a surgical team takes on," said Erin Hofmann, Chief Executive Officer of TJO. "KISS brings real simplicity and value to that complexity, allowing surgeons to adapt their surgical plan as needed to help improve patient outcomes.“

"I have been using articulating spacers for thirty years, offering earlier knee motion without increasing infection risk or spacer failure, so patients can keep moving between stages," said Aaron A. Hofmann, MD, Co-Founder and Chairman of TJO. "Seeing TJO bring a purpose-built spacer system to surgeons is especially meaningful to me." 

KISS received FDA 510(k) clearance in July 2026 as part of the Klassic® Knee System. It includes a dual indication for temporary use for up to 180 days as an adjunct to total knee replacement in patients undergoing a two-stage procedure due to a septic process, and for permanent primary or revision TKA procedures. 

KISS will debut at the American Association of Hip and Knee Surgeons (AAHKS) Annual Meeting, November 5–8, 2026, in Grapevine, Texas. Surgeons can TJO’s Klassic® Infection Spacer, Klassic® Revision Knee, and Universal® Cone Systems at Booth 1503.
