Open Label, Randomized, Blinded Study to Evaluate the Efficacy of Aquamantys System for Reducing the Transfusion Requirements Associated With the Anterior-Supine Intermuscular (ASI) Approach for Total Hip Arthroplasty (THA)
In Brief
A clinical study evaluating Aquamantys and standard electrocautery (Bovie) for Osteoarthritis, Hip and 4 related conditions. Completed, enrolled 200 participants across 1 site.
Detailed Summary
The purpose of this study is to establish whether or not there is a clinical advantage to the use of Aquamantys® System from Medtronic Advanced Energy (formerly Salient Surgical Technologies) in patients undergoing primary total hip arthroplasty via the anterior supine intermuscular surgical approach in terms of blood loss, transfusion and wound healing. Wound healing will be assessed by a blinded observer and based upon a simple and subjective criteria: a) as expected, b) better than expected or c) worse than expected. The blinded observer is experienced in the care of the surgical patient and wound evaluation.

Interventions
Primary THA via the ASI approach will be performed using the Aquamantys Malleable Bipolar Sealer. The Aquamantys is a bipolar device that combines radio-frequency energy and saline to gently reach targeted tissue and provide a biomechanical seal. The saline acts as a conduit to allow the energy to penetrate the tissue from 1 to 2 mm where the collagen is transformed thus providing the seal. The saline also helps cool the tissue which allows for gentle handling of tissue, eliminating the black char that is a port for infection. The surgeon uses the Aquamantys to assist in tissue dissection, cauterize vessels, and to pre-treat fat pad in front of capsule prior to excision, to treat the entire anterior hip capsule prior to excision, treat oozing bone surfaces not covered by an implant.
Primary total hip arthroplasty via an anterior supine intermuscular approach will be performed with the assistance of standard electrocautery. The electrocautery is used in tissue dissection and to cauterize bleeding vessels.
