Controlling Blood Loss During Hip Procedures

The Aquamantys System controls blood loss during hip surgery

The Aquamantys® System uses patented Transcollation® technology, a combination of radiofrequency (RF) energy and saline that provides hemostatic sealing of soft tisuue and bone during surgery. When used during total hip arthroplasty (THA), the Aquamantys System provides benefits for both surgeons and patients – reducing transfusion rates by minimizing intra-operative blood loss.1,2,*

Proper surgical technique is important to achieve optimal results with Transcollation technology. Use of the Aquamantys System in hip replacement surgery provides the following clinical benefits:

  • Reduces transfusion rates1,2,*
  • Reduces post-operative drainage1,2
  • Helps maintain hemoglobin levels1,3

The Aquamantys System can be used during the Direct Anterior approach to minimize soft tissue bleeding encountered during the procedure.

Hip procedures where Aquamantys devices are commonly utilized include:

  • Total hip replacement
  • Hemiarthroplasty
  • Hip resurfacing
  • Revision
  • Bilateral

Choice of hip replacement approaches vary by each surgeon. Regardless of the preference, Transcollation technology can address the following areas that may bleed during surgery:

Direct anterior approach

  • Tissue surrounding superficial vessels* in the deep subcuticular layer
  • Tissue surrounding the anterior circumflex vessels* (ascending branch) encountered during the initial approach
  • Tissue surrounding the posterior circumflex vessels* encountered during capsular release
  • Tissue surrounding the medial vessels* of the obturator branches, which may bleed and retract
  • Obturator region – during periacetabular treatment before and after reaming

Anterolateral approach

  • Tissue surrounding the superficial vessels* in the deep subcuticular layer
  • Inferior abductor muscles prior to and after release
  • Periacetabular treatment prior to, during, and following femoral head removal

Posterolateral approach

  • Tissue surrounding the superficial vessels* in the deep subcuticular layer
  • Short external rotators, capsular, and posterior arterial perforators before and after the release
  • Periacetabular treatment prior to, during and following femoral head removal

Controlling Blood Loss During Knee Procedures

The Aquamantys System controls blood loss during knee surgery

Every day, surgeons use the Aquamantys® System with patented Transcollation® technology, a combination of radiofrequency (RF) energy and saline that provides hemostatic sealing of soft tissue and bone during surgery and helps surgeons proactively address bleeding during orthopaedic procedures.

Proper surgical technique is important to achieve optimal results with Transcollation technology. Studies have shown that, when used during knee replacement procedures, the Aquamantys System provides the following clinical benefits:

  • Reduces transfusion rates by minimizing intra- and post-operative blood loss1,2,*
  • Reduces post-operative drainage1,2
  • Reduces post-operative incidence of hemarthrosis, which may lead to a reduction in pain and swelling3,*

Knee procedures where Aquamantys devices are commonly utilized include:

  • Primary total knee replacement
  • Partial knee replacement
  • Revision
  • Bilateral

In a prospective survey listing more than 50 patient concerns prior to knee or hip arthroplasty, "pain immediately after surgery" was the most common concern.4 In total knee arthroplasty, post-operative pain can be related to tourniquet usage: patients subjected to a tourniquet experienced significantly more pain than those who had surgery without a tourniquet.5-8

Surgeons may help reduce their patients’ post-operative pain by eliminating or reducing tourniquet use, and utilizing the Aquamantys System to control intraoperative bleeding.1,2
