Robotic arm technology enables a new level of precision in total hip replacement
FORT LAUDERDALE, Fla. (September 19, 2011) – Holy Cross Hospital, the first in the world to perform a MAKOplasty robotic arm-assisted partial knee procedure in 2006, is now the first in Broward County to offer MAKOplasty® Hip, the latest innovation in total hip replacement surgery performed using the RIO® system, a highly advanced, surgeon-controlled robotic arm system that enables the accurate alignment and positioning of implants.
At the forefront of orthopedic innovation, Holy Cross was among the first to pioneer total hip arthroplasty, robotic arm-assisted knee surgery, all-arthroscopic rotator cuff repairs, arthroscopic hip surgery and reverse shoulder replacement. The addition of MAKOplasty robotic arm assisted total hip replacement continues our commitment to providing our community with access to leading technologies and superior patient care.
"Everyone's anatomy is unique and ensuring that implants are correctly positioned can improve both surgical outcomes and implant lifespans. The robotic arm allows greater precision," said David Padden, MD of the Holy Cross Orthopedic Institute, Lighthouse Point Orthopedics practice.
Accurate alignment and positioning of implants using traditional manual total hip replacement techniques can be challenging. Massachusetts General Hospital recently reported in Clinical Orthopaedics and Related Research that of 1,823 hip replacement patients treated over a sustained period of study, only 50% had acetabular cups positioned in the acceptable range of proper inclination and version.
Here’s how MAKOplasty Hip works: The RIO system provides a patient-specific 3-D image of the patient’s hip based on a pre-operative CT scan. Using the 3-D model, the surgeon can then plan the optimal size and position of hip implant components. An implant consists of a cup and liner placed in the acetabulum or the socket of the pelvis, and a femoral component with a femoral head and stem. The position of these components is critical for proper biomechanical reconstruction of the hip.
During surgery, RIO provides visualization of the joint and biomechanical data to guide the bone preparation and implant positioning to match the pre-surgical plan. First the surgeon prepares the femoral bone for the implant, and subsequently measures the femoral component’s position with the RIO. Next the surgeon uses the robotic arm to accurately ream and shape the acetabulum, and then implant the cup at the correct depth and orientation. Finally the surgeon implants the femoral implant and RIO provides summary data to confirm the hip implants are aligned according to plan.
MAKOplasty Hip is designed to assist surgeons in attaining a new level of reproducible precision in surgery, to restore patients’ confidence in their mobility and help them return to active lifestyles.
MAKOplasty Hip may be a treatment option for people who suffer from either non-inflammatory or inflammatory degenerative joint disease.
In January, the hospital established the Holy Cross Orthopedic Research Institute to advance the field through high-quality, clinical and basic science, research and education. The orthopedic program at Holy Cross is also responsible for establishing key protocols for orthopedic rehabilitation and introducing leading-edge techniques to speed recovery and minimize pain. In addition, surgeons and researchers at Holy Cross have published more than 30 peer-reviewed articles on orthopedics.
