Managing massive bone loss after infected total knee arthroplasty with a custom-made spacer.

ABSTRACT

Periprosthetic infection is an increasingly prevalent and challenging problem in joint reconstruction. We present a technical report of a custom spacer for management of an infected total knee arthroplasty (TKA) and concomitant severe bone loss. The spacer was designed to provide sufficient leg length, soft tissue tension, and limb stability in preparation for ultimate limb reconstruction. This technique and custom spacer serve as an alternative for managing significant bone loss in infected knee arthroplasty.
