Orthopedics, Orthopaedics, Total knee surgery, total hip surgeryNewton Medical Center (NMC) is the second hospital in the state to offer Stryker’s Mako Robotic-Arm Assisted Total Hip replacement procedures. This latest advancement in joint replacement surgery is transforming the way joint replacement procedures are performed.

Robotic-arm assisted surgery is a new approach to joint replacement that offers the potential for a higher level of patient-specific implant alignment and positioning.1-2 The technology allows surgeons to create a patient-specific 3D plan and perform joint replacement surgery using a surgeon controlled robotic-arm that helps the surgeon execute the procedure with a high degree of accuracy.3

NMC board-certified orthopaedic surgeon J. Scott Pigg, M.D. is specially trained in robotic-arm assisted surgery.

“This technology is changing the way joint replacement surgeries are performed,” said Dr. Pigg. “Using a virtual 3D model, the Mako System allows me to personalize each patient’s surgical plan pre-operatively, so there is a clear plan for how to position the implant before entering the operating room. During surgery, I can validate that plan and make any necessary adjustments, while the robotic-arm then allows us to execute that plan with a high level of accuracy and predictability. The combination of these three features of the system has the potential to lead to better outcomes and higher patient satisfaction.”

The Mako Total Hip application is a treatment option for adults who suffer from degenerative joint disease of the hip. During surgery, the surgeon guides the robotic-arm during bone preparation to prepare the hip socket and position the implant according to the pre-determined surgical plan. In cadaveric studies, Mako total hip replacement acetabular cup placement has been shown to be four times more accurate and reproducible than manual total hip replacement procedures.1

“Newton Medical Center strives to be a leader in healthcare. And, whenever possible, we support our medical staff by placing innovative, leading edge technology into their hands,” said Val Gleason, president and chief executive officer. “It is part of our commitment to provide our community with outstanding healthcare.”
