2. Surgical approach matters
For hip replacement patients, the anterior approach is minimally invasive and avoids cutting muscle fibers, which allows the soft tissue in the joint to heal quickly.

3. A minimally invasive approach
Requires 3-4 inch incision vs 8-12 inches with traditional hip replacement
Hip accessed through a natural interval between muscles vs cutting muscle tissue
Anterior Approach
Traditional Approach

4. Advantages over other approaches
Preserves muscle tissue
Fewer post-operative hip precautions1
Potentially lower dislocation risk2-4

5. Less tissue damage means faster recovery for patients1
On their feet and discharged from the hospital in 2-3 days
Discharge to home vs rehab more likely
Reduced pain scores and pain medication use at two weeks post-op
More rapid progression from walker to cane to no use of walking aid
After full physical rehabilitation, most patients can return to regular activity and exercise without any pain. They will regain full range of motion with no 90-degree angle restriction.

7. Supportive clinical data
Hip Dislocation: Are Hip Precautions Necessary in Anterior Approaches?1
AA and anterolateral approach performed in 2764 THA’s over 3 years
Patients given no traditional functional post-op restrictions (elevated seats, driving restrictions, etc.)
Low incidence of post-operative dislocation (15%); no-restriction protocol does not increase dislocation after primary THA
Comparison of Minimally Invasive Direct Anterior Versus Posterior Total Hip Arthroplasty Based on Inflammation and Muscle Damage Markers2
Prospective analysis of 29 AA hip patients vs. 28 posterior approach
AA associated with significantly less creatinine kinase (CK) post-op, indicating less muscle damage than the posterior approach
Does the Direct Anterior Approach in THA Offer Faster Rehabilitation and Comparable Safety to the Posterior Approach?3
Prospective, comparative, nonrandomized study of 120 patients (60 AA, 60 posterior)
Functional recovery assessed via a variety of methods (pain score, patient diary, timed up and go (TUG), etc.)
Functional recovery faster at two weeks in AA patients based on two of the seven metrics
No differences observed with other metrics or beyond six weeks
Early Outcome Comparison Between the Direct Anterior Approach and the Mini-Incision Posterior Approach for Primary Total Hip Arthroplasty4
150 consecutive primary THA’s from a single surgeon evaluated – 50 from posterior approach, 50 during AA learning curve, 50 when AA was routine
AA groups had reduced LOS (2.9 and 2.7 days vs. 3.9 days for posterior; p<0.0001) and discharge to home vs rehab was more likely (80% and 84% vs. 56% in posterior group; p= )
AA groups resulted in less use of assistive devices (88% and 80% vs. 32% in posterior group; p<0.0001) and narcotics at 6 weeks (8% and 2% vs. 33% in posterior group; p=0.0026)

Hemostatic Sealing of Soft Tissue and Bone
Radiofrequency (RF) energy + saline = Transcollation® technology
Step 1
RF energy and saline is applied to tissue
Step 2
Heat-induced tissue
shrinkage occurs
Step 3
Vessels up to 1 mm may be occluded

11. Aquamantys clinical data
Broad plane hemostasis and more control over intraoperative coagulation
Reduction in intraoperative blood loss has been associated with a statistically significant reduction in transfusions (21.2% vs 23.5%, p=0.0457) and hematomas (0.2% vs 0.8%, p= ) 1
Has been associated with a statistically significant reduction in length of stay for patients (2.86 vs days, p<0.0001)1
As part of a comprehensive blood management program, may be more effective at reducing blood transfusions and the cost and complications associated with intraoperative blood loss2,3

12. Aquamantys clinical data
Compared to traditional electrosurgery
Bipolar tip design with saline coverage allows broad hemostatic control in oozing tissue and active bleeding while penetrating deep to reach hidden bleeders, resulting in reduced blood loss and potentially lower transfusion rates1,2
Offers a definitive hemostatic solution by uniformly sealing bleeding tissues
