CarboJet® CO2 Bone Preparation System

Why Use CarboJet to Clean Bone?

Advantages of a cleaner & drier bone bed:

• Facilitates Tourniquet-free TKA, which has been shown to reduce pain and opioid use
• Increases Cement Penetration Into the Bone Bed
• Increases Bone-Cement Interface Strength
• Reduces Opportunity for Micro-Emboli
• Removes Immunogenic Elements from Osteochondral Allografts (OCA).

Aseptic loosening is now recognized as the predominant failure mode in primary knee arthroplasty. A recent study of 938 primary knees found that aseptic loosening was the most common mechanism of failure, accounting for 28% of all failures. In UKA, aseptic loosening accounted for more than 60% of failures. These data underscore the importance of achieving optimal cement fixation via meticulous cleaning and drying of the bone bed.

CarboJet’s CO2 gas jet quickly and thoroughly cleans and dries the bone bed by bringing blood, saline and, most importantly, lipids/fatty marrow elements to the surface where they are easily collected and removed. Cleaning and drying with CarboJet takes no more time than is typically required for drying with lap sponges. The superior cleaning achieved with CarboJet improves cement penetration depth thus offering the potential for a reduction in bone cement interface stress and increased cement mantle toughness. Increased bone-cement interface strength is the result.

How does it work?


Saline lavage is effective at removing gross debris, but fluid mixing in the interstices of bone prevents thorough cleaning.


A compressed gas jet effectively displaces fluid and fluid- suspended debris, thereby cleaning and drying porous structures.

Why CO2?

Compressed CO2 gas has been employed as an insufflation medium in laparoscopic procedures for decades and is readily available at all hospitals.

Nozzles are available for use in TKA, UKA, THA, TSA and other cemented reconstructive applications.


In clinical use since 1993, CarboJet has been shown to be safe and effective in multiple clinical studies and in tens of thousands of joint reconstructive procedures. Give it a try and discover why so many surgeons are making CarboJet a standard part of their cement technique.

Role of CarboJet in Tourniquet-free TKA and Opioid Use

A recent study, “Reducing Opiate Use: The Tourniquetless TKA” presented by R. Michael Meneghini, M.D., demonstrates reduced opioid consumption in female patients when a tourniquet was not used in total knee arthroplasty (TKA). CarboJet was used to maximize cement interdigitation – an essential component of the tourniquetless TKA technique. The ability to reduce opioid consumption using this technique is significant, since opioid addiction has become a national crisis, and protocols that result in reduced patient pain are being sought.

Surgeon Testimonials

“I use it on Uni Knees.  We often get a lot of bone bleeding – even with a tourniquet during cementation.  The CarboJet dries the bone superbly for implantation.  Outstanding addition to my surgical technique!!”

Airell Nygaard, MD, Yosemite Joint Replacement

“CarboJet provides my patients with a much cleaner, drier bone bed allowing for better cement penetration and hence a better mechanical interface between bone and implant for secure long-term fixation.”

Richard “Dickey” Jones, MD, Orthopedic Specialists, Dallas, TX

“I have made gas jet lavage with CarboJet the critical last step in bone preparation in all my cemented arthroplasty cases. The removal of additional marrow elements that could otherwise form embolic debris during cement pressurization is important to patient safety.”

H.M. “Mac” Reynolds, MD, Oakland, California, In Memorium
