Mako Robotic Assisted Surgery

Game Changer in Knee Replacement

King's Daughters is pleased to now offer total knee replacements using Stryker’s robotic-arm assisted Mako System in both Ashland and Portsmouth. This latest advancement in joint replacement surgery transforms the way total knee replacements are performed.

Each patient is unique and can experience joint pain for different reasons. Pain from arthritis and joint degeneration can be constant or come and go and can occur with movement or after a period of rest. Knee replacement surgery can help relieve pain and restore function in severely diseased knee joints.

The Mako Robotic-Arm Assisted Surgery System is a revolutionary new procedure that approaches total knee replacement like the unique individual you are.

How the Mako System works

Through CT-based 3D modeling, orthopedic surgeons George Aitken, M.D., Steven Carawan, M.D., Felix Cheung, M.D., Brock Johnson, M.D., Laura Reese, D.O., and Gerry Trinidad, M.D., use the Mako Total Knee application to create a personalized surgical plan and identify the implant size, orientation and alignment based on each patient’s specific diagnosis and unique anatomy. During surgery, surgeons can validate that plan and make any necessary adjustments while controlling the robotic arm to perform the procedure.

“This is a patient-specific procedure. Everybody’s different. By using the Mako, we’re able to make the knee fit the patient as opposed to the patient fitting the knee,” said Ryan Ison, vice president, King’s Daughters Integrated Practices.

The Mako System offers tremendous benefits to patients. The surgeon is able to make more precise incisions, helping to preserve healthy bone and protect soft tissue and ligaments. This leads to improved outcomes and, potentially, longer-lasting knee replacements.

Mako surgery is available in both Ashland and Portsmouth.
