Abstract
Asepting loosening by polyethylen wears is on of the main problems in total knee replacement. In the last years, the major improvement is about matherials. The polyethylene remains the major problems for long term results of total knee replacement despite new types of polyethylenes like cross linked or high reticulation. From to 2 years a new matherial (Oxinium) for femoral component has been avaluated; Oxinium is an high temperature and oxidation procedure to trasform the articular surface like a ceramic. In this paper early results with this total knee replacement are reported and the advantages of this new matherial are discussed.
110 primary Oxinium-Profix were evaluated. Mean follow up is 18 months ( min2 max 26). Mean age is 67 years (53 yrs– 74yrs). Both components were cemented. In all cases PCL was retained. Never patella was replaced. Lateral release with out-in technique was performed in all cases. The Knee Society scoring system was used to assess patients both clinically and radiografically.
Clinical and radiographic results are promising despite the short follow-up. Oxiunium seems to be a safe matherial, especially for young patients because of low rate of wear. However, only a long term follow up could confirm the intial promising results
