In orthopedic surgery, Arista is applied in which procedure?

• A. Total Knee Replacement
• B. Rotator Cuff Repair
• C. Spinal Fusion
• D. Hip Arthroplasty

Answer: (A)

Arista is used to achieve rapid, local hemostasis on raw bone and soft-tissue surfaces by delivering a sponge-like material that absorbs water and concentrates clotting factors at the site. In total knee replacement, there are large exposed cancellous bone surfaces after cutting and preparing the joint. This creates brisk, diffuse oozing that is difficult to control with suction and pressure alone. Sprinkling Arista onto these bleeding surfaces provides prompt, localized coagulation, helping to keep the surgical field clear and reducing postoperative bleeding.

While other procedures involve bleeding too, the knee replacement scenario presents the most extensive exposed bone surfaces where Arista’s mechanism is particularly advantageous, making it the best fit for this setting.
