Convened under the auspicious of esteemed endorsers - ISTA

The stem has been designed to address the larger possible variety of anatomical variations too.The stem therefore features innovative design concepts including the latest generation ModularNeck System, coupled with a revolutionary manufacturing process and surface engineeringtechnology. This manufacturing process (Powder manufacturing Technology) and IngrowthSurface (Ti-Por) will be also briefly discussed in the presentation.Our early clinical results will be also presented (150 stem-one yr. maximum follow up will bepresented) although they are not the main purpose of our study oriented more on the noveldesign and technological manufacturing advancement.The feed-back we had so far with this state of the art implant is extremely encouraging. Ofcourse further data collection and longer follow up will be needed in order to confirm theseearly promising results.Saturday, October 9, 2010, 11:15-11:50Session A20: Knee Arthritis: Early InterventionTrufit Resorbable Scaffolds: 2 Yy Clinical Good Results Associated toDelayed Biological Incorporation in the Knee*Fabio Valerio Sciarretta - CLINICA NOSTRA SIGNORA DELLA MERCEDE - Roma,ITALY*Email: fabio.sciarretta@tin.itTrufit resorbable scaffolds, made of semiporous copolymer, are press-fit introduced in chondraldefects of articular surfaces in order to promote filling and regeneration of damaged bone andcartilage tissues. In another previous work, we have presented our good and promising resultsobtanied at 1 yy follow-up. Then, we have had the chance to go on on follow-ups and checkpatients through second-look arthroscopies and serial MRI's: IKDC score showed 38 pointsimprovement. WOMAC score showed statistically significant pain improvement in 89% ofcases and function improvement in 86% of cases. Serial MRI's of the knees showed progressiveincorporation of the synthetic plugs and no adverse inflammatory reaction. Second-lookarthroscopies showed complete and flush fill of the defects and their resurfacing with hyalineliketissue under different stages of maturation.Recently, we have been able to check, clinically and by serial MRI's, the first patients operated24 months ago. Despite the mantainance of clinical very good results, as showed by otherauthors, MRI images showed a delayed biologic process of incorporation of the plugs. Thisfinding has not to be misinterpreted as an implant failure and the post-op rehabilitation has tobe continued in order to give regenerating cartilage time to complete the maturation process.file:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
