    New Clinical Research Highlights Benefits of iTotal®

    Results from the 2014 British Association for Surgery of the Knee (BASK) meeting highlight excellent patient satisfaction, normal feel and neutral alignment critical to long-term survivorship. ConforMIS clinical results presented at BASK include:

    • “Early Outcomes Utilizing a First-Generation Customized Patient-Specific TKA Implant” (P0185). Lead researcher William Kurtz, M.D. shared the clinical results of patients implanted with the first-generation customized iTotal implant. In a population of 89 patients and 106 knees treated, no patients required blood transfusions and mean pre-op range of motion (ROM) was regained within an average of four months. No patients reported any dissatisfaction in four of five Knee Scoring System (KSS) categories, including pain while sitting and function while performing recreational activities. Unprecedented to any published reports on standard, off-the-shelf implants, all patients receiving iTotal reported a “normal” feeling knee seven months after the procedure. View poster.
    • “Intraoperative Assessment of Mechanical Alignment Accuracy Determined by Computer Navigation in a Patient-Specific TKA (Total Knee Arthroplasty) System” (Session 6). Data presented by Gary A. Levengood, M.D. demonstrated that in a population of 63 patients treated with iTotal, 100% achieved alignment within ± 2° of the neutral mechanical axis. Restoration of alignment within 3° of neutral is a widely confirmed indicator of improved long-term survivorship in TKA. View poster.
    • “In Vivo Tibial Fit Analysis of Customized, Patient-Specific TKA Versus Off-the-Shelf TKA” (P0181). Data demonstrated that use of iTotal significantly improves tibial fit when compared to off-the-shelf TKA implants. The study concluded, “this could play an important role in reducing knee pain and patient dissatisfaction … as well as implant loosening.” View poster.
