New Infection Spacer System Expands Options for Revision Knee Arthroplasty .

Periprosthetic joint infection remains among the most challenging complications of knee replacement. Total Joint Orthopedics has launched its Klassic Infection Spacer System, which received FDA clearance for temporary implantation for up to 180 days during staged infection treatment and for permanent implantation in appropriate knee replacement procedures. Unlike conventional cement spacers, the system incorporates metal and polyethylene components intended to provide an articulating construct. The launch expands revision options, although comparative evidence on infection eradication, function and complications is still needed.
