What is it indicated for?

The Duracon® Extra-Small Stabilizer Tibial insert and Baseplate are intended to be used with previously released Duracon femoral and patellar components as a total knee system in primary or revision cemented total knee arthroplasty. These components are specificaily intended to be used in situations where the posterior cruciate ligament.is not intact, not present, or cannot be repaired. The collateral ligaments should be intact, or repaired so that adequate mediolateral stability is present. These components are intended to be implanted using bone cement in small boned, skeletally mature individuals.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
