Outcome Measures

Primary Outcomes (1)

  • Blood Loss and Post-Operative Transfusion Rate

    To reduce blood loss and post-operative transfusion rates in patients undergoing total joint arthroplasty. This will be achieved using the Aquamantys system. The Aquamantys system provides transcollation which shrinks the collagen fibers in the walls of blood vessels, effectively sealing the blood vessels up to 1mm in diameter, resulting in the reduction of bleeding from soft tissue.

    14 days

Secondary Outcomes (1)

  • Operative room and total hospital costs

    14 days

Other Outcomes (1)

  • Change in hemoglobin and hematocrit from baseline (pre-op)

    14 days

Study Arms (2)

ASEPTIC Revision TKA & Aquamantys System

ACTIVE COMPARATOR

Single-stage revision TKA cases performed for aseptic failure requiring an extended osteotomy for component removal and intra-operative blood management (bipolar sealing) with the Aquamantys® System. These will be compared to in-house matched historic control using patients presenting with ASEPTIC failed primary TKA and revised without use of the Aquamantys® System.

Procedure: Aquamantys System

SEPTIC Revision TKA & Aquamantys System

ACTIVE COMPARATOR

Single-stage revision TKA cases performed for septic failure requiring an extended osteotomy for component removal and intra-operative blood management (bipolar sealing) with the Aquamantys® System. These will be compared to in-house matched historic control using patients presenting with SEPTIC failed primary TKA revised without use of the Aquamantys® System.

Procedure: Aquamantys System

Interventions

The use of the saline-coupled bipolar sealing technology (Aquamantys® System, Medtronic Advanced Energy, LLC, Portsmouth, NH, USA) uses bipolar radiofrequency energy combined with a continuous-flow saline at the electrode tip to prevent tissue temperatures from exceeding 100 °C thus minimizing tissue charring. The temperature achieved is sufficient to induce a process called Transcollation(TM) which shrinks the collagen fibers in the walls of blood vessels, effectively sealing the blood vessels up to 1mm in diameter, resulting in the reduction of bleeding from soft tissue.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The patient is greater than 18 years of age
  • Patients following failure of primary, unilateral TKA
  • The degree of revision requires the use of an extended osteotomy for component removal
  • Patient has participated in the informed consent process and has signed an Ethics Committee approved informed consent

You may not qualify if:

  • Patients presenting with a history of bleeding disorders and/or are on chronic blood anticoagulation therapy
  • Patients presenting with an internal cardiac defibrillator
  • Women who are pregnant
  • Prisoner or transient
  • Recent history of known narcotic abuse
  • Any significant psychological disturbance past or present, that could impair the consent process or ability to complete subject self-report questionnaires
  • Subject unwilling to undergo blood transfusion, if necessary
