Vitagel Revision Total Knee Arthroplasty

Stopped early · Not applicable

Conditions studied: Failed Total Knee Arthroplasty

In brief

This prospective study will evaluate the effectiveness of Vitagel (VG) in reducing blood loss associated with Revision Total Knee Arthroplasty (RTKA) procedures by assessing the patient's change in hemoglobin/hematocrit. Transfusion rates with the use of VG compared to the current standard of care will also be evaluated. The effectiveness of VG to potentially reduce pain, and increase return to function and quality of life will be assessed through the modified Knee Injury and Osteoarthritis Outcome Score (Modified KOOS), the Numerical Assessment Pain Scale (NAPS), and the SF-12 health survey. Analgesic use will be recorded post-operatively.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients must meet all of the following criteria in order to be considered appropriate candidates for participation in the study:
• Is scheduled for RTKA (may be the second stage/reimplantation of a two-stage revision for infection);
• Is able and willing to provide voluntary written informed consent for participation in the study and able to comply with protocol requirements;
• Is between the ages of 18 and 85 at the time of surgery. Both male and female will be included;
• Is physically and mentally willing and able to comply with the clinical and evaluation follow-up schedule;

You may not qualify if…

• The following exclusion criteria address safety and follow-up concerns or contraindications that could confound the study. If a patient exhibits any one of the following criteria, the patient is not eligible to participate in this study:
• Is known to be sensitive to any materials of bovine origin;
• Is undergoing a bilateral RTKA;
• Is undergoing a single component revision (i.e. tibial or femoral component only)
• Is undergoing a polyethylene revision only
• Is predonating autologous blood;
• Have a preoperative platelet count of less than 100,000
• Have a previous history of venous thromboembolism or deep vein thrombosis;
• Have a medical condition requiring anticoagulation
• Currently using Coumadin;
• Have a history of Heparin induced thrombocytopenia or Lovenox induced thrombocytopenia;
• Have a history of rheumatoid arthritis or inflammatory arthritis;
• Have peripheral vascular disease;
• Have evidence of bleeding or metabolic-based hemolytic disorder (hemophilia or anticoagulation use), or hypercoaguable disorder;
• Have a history of liver disease. Patients with liver dysfunction from cirrhosis or hepatitis may have impaired production of factors in the clotting cascade which may make these individuals more prone to bleed, especially with the use of anticoagulants. For this reason, these patients will also be excluded from the study if a baseline INR is greater than 1.3 or APTT greater than 32.4;
• Have a history of failed treatment for abuse of, or are actively abusing, illegal drugs, solvents, or alcohol;
• Have a systemic infection or infection at site of surgery;
• Is a prisoner;
• Is pregnant or nursing and;
• Have a condition deemed by physician or medical staff to be non-conducive to patient's ability to complete the study, or a potential risk to the patient's health and well-being.

• Use during the procedure of any other approved or unapproved product for the purpose of hemostasis
