Pyrocarbon Implant Replacement (PIR) System (Prod 150219)






About Pyrocarbon Implant Replacement (PIR) System (Prod 150219)

The PIR System, developed in conjunction with the not-for-profit Fellowship of Orthopaedic Researchers, is intended to treat patients with focal chondral and osteochondral defects of the medial femoral condyle of the knee. The PIR System targets patients too young for a total knee replacement; but either poor candidates for, or have failed cartilage regenerative procedures, as well as those unable to devote the rehabilitation time necessary for these procedures. 

 
The PIR System is a one-piece implant, fabricated from On-X pyrolytic carbon, with hydroxyapatite coating on all bone interfacing surfaces. The implant is placed as a hemi-arthroplasty, through a minimally invasive surgical approach, and articulates with the native tibia cartilage.  The unique wear properties of the System's pyrolytic carbon material can extend the functional life of the implant, making it appealing to both surgeons and patients.  And, unlike conventional knee replacement procedures, the tissue sparing PIR System replaces only the damaged cartilage, while retaining healthy tissue.
