Spring Hill Medical Center is unveiling its latest tool to help patients. It’s a robotic arm to assist in surgeries for partial knee and total hip replacements.
So, this is how it works. Patients go through CAT-scans and surgeons use information from that to create pre-operative plans for the placement of their implants. During operation, the surgeon is in control, but the robotic arm limits their movement – that keeps the accuracy within one-tenth of a millimeter.
“A huge and overwhelming benefit is really being able to place those components accurately. We know from multiple studies that placing implants in their correct orientation leads to better outcomes, fewer complication, and enhance the longevity of the implant. So, we want patients to have a great result but also a very durable result.” – Dr. Matthew Barber, AOC
Spring Hill Medical Center is the first hospital in the Mobile area to offer operations with this device.
Springhill Medical Center is the first hospital in the Mobile area to offer Stryker’s Mako Robotic-Arm Assisted Partial Knee and Total Hip replacement procedures. This latest advancement in joint replacement surgery is transforming the way joint replacement procedures are performed.
“This system allows us to be extremely precise in the planning, preparation and implantation of joint prostheses to help patients achieve the best possible results,” said Dr. Matthew Barber, AOC Joint Replacement Specialist.
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. 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.
“Mako is changing the way joint replacement surgeries are performed,” said Dr. Barber. Using a virtual 3D model, the Mako System allows the surgeons to personalize each patient’s surgical plan pre-operatively, so there is a clear plan for how the surgeon will position the implant before entering the operating room. During surgery, the surgeon can validate that plan and make any necessary adjustments, while the robotic-arm then allows the surgeon 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 Partial Knee application is a treatment option designed to relieve the pain caused by joint degeneration due to osteoarthritis that has not yet progressed to all three compartments of the knee. Following the personalized pre-operative plan, the surgeon guides the robotic-arm during bone preparation to execute the predetermined surgical plan and to position the implant. By selectively targeting only the part of the knee damaged by osteoarthritis, surgeons can resurface the diseased portion of the knee while helping to spare the healthy bone and ligaments surrounding the knee joint. Studies have shown robotic-arm assisted partial knee replacement to be two to three times more accurate than manual partial knee replacement procedures.
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 predetermined surgical plan. In cadaveric studies, Mako total hip replacement acetabular cup replacement has been shown to be four times more accurate and reproducible than manual total hip replacement procedures.
“AOC is very proud to have this innovative technology in the greater Mobile area,” said Dr. Barber. “I am excited about leveraging the use of robotic technology to produce better outcomes for our patients.”
