Kinamed CarboJet Study: Tourniquetless TKR May Decrease Pain, Opiod Use

Share:

Kinamed, developer of the CarboJet® CO2 Bone Preparation system, announced publication of a clinical study examining its use in traditional tourniquet vs. tourniquetless total knee replacement (TKR). Results indicate that female patients in the no-tourniquet/CarboJet group experienced significantly less post-op pain and consumed fewer opioids vs. those in the tourniquet group.

Surgical protocols that minimize opiod use, such as tourniquet elimination, are highly sought-after given the risks of opiod prescription. When performing tourniquetless TKR, however, an optimal cement technique may be challenged due to additional fluid debris in the bone and at implant interfaces. 

CarboJet is designed to use medical-grade compressed carbon dioxide gas to remove lipids/fatty marrow elements, blood and saline from the bone surface prior to cement application. This helps support appropriate penetration of the cement to avoid aseptic implant loosening, a common failure of the TKR procedure.
