Orthovita Announces Presentation of Clinical Results Evaluating Vitagel(TM) Surgical Hemostat in Reducing Blood Loss During Primary Unilateral Total Knee Arthroplasty

MALVERN, Pa.--(Healthcare Sales & Marketing Network)-- Orthovita, Inc. (NASDAQ:VITA ), an orthobiologics and biosurgery company, is pleased to announce that Michael Bloomfield, M.D., of Cleveland Clinic, presented results of a study entitled “Prospective Randomized Evaluation of a Collagen/Thrombin and Autologous Platelet Hemostatic Agent During Total Knee Arthroplasty” on Friday, April 8, at the 29th Annual Meeting of the Mid-America Orthopaedic Association in Tucson, Arizona. Wael Barsoum, M.D. and Alison Klika, M.S. of the Cleveland Clinic, Cleveland OH, served as the principal investigators of the study.

The prospective, double-blind, randomized 100-patient study evaluated the ability of Vitagel™ Surgical Hemostat (Vitagel), a microfibrillar collagen, thrombin and autologous plasma composite hemostatic agent, to reduce blood loss during primary unilateral total knee arthroplasty. In this study, standard hemostasis with Vitagel was found to reduce blood transfusions following primary total knee arthroplasty as compared to standard hemostasis alone (electrocautery). Key findings were:

  • Transfusion requirements were significantly lower in the Vitagel group (0 blood transfusions in the 50-patient Vitagel arm compared to 5 transfusions in the 50 patient control arm; p=0.007).
  • There was a trend toward higher hemoglobin levels in the Vitagel group starting on the second postoperative day; this trend achieved significance by the fourth day (10.0±1.0 vs. 8.8±1.1; p=0.01).
  • No adverse events were attributed to the use of Vitagel.

Antony Koblish, President and CEO of Orthovita, stated, “This study represents an important resource for surgeons seeking options to minimize bleeding and the need for transfusions associated with joint replacement surgery. As a novel biomaterials company, Orthovita is committed to substantiating the use of products like Vitagel based upon clinical evidence.”

Dr. Bloomfield received the Mid-America Orthopaedic Association E. W. Johnson, Jr., M.D. Physician-In-Training Award for his contribution to the study.
