 Houston Northwest Medical Center uses an image-free navigation system for total knee replacement surgeries. The Stryker Navigation System for total knee replacement surgeries is designed to improve the alignment of the knee replacement which can be an important factor in the successful long-term outcome of the surgery.
Recent advances in computer technology have led to the advent of navigation systems which seek to address the limitations of conventional alignment and implant positioning tools. Various computer-assisted navigation systems are in use in clinical settings, designed to provide a more precise positioning of total knee replacement components with conventional alignment tools.
The software and hardware used for these total knee replacements is based off an invention developed by Albert Cuellar, M.D., an orthopedic surgeon on the medical staff at Houston Northwest Medical Center. Stryker collaborated with Dr. Cuellar on his invention, called eNdtrac ASM Knee software, for total knee replacement surgery.
Dr. Cuellar’s dedication to excellence in orthopedics and patient care inspired him to develop a process, technique and algorithm designed to perform total knee replacement surgeries with increased accuracy and efficiency. “This navigated total knee replacement surgery method is designed to provide surgeons with the proper registration of the anatomy at the time of surgery,” says Albert Cuellar, MD. “Thus, allowing for more accurate navigation around the incisions and more accurate placement of the implant. Improved alignment of the knee replacement may help increase strength, stability, and range of motion,” adds Albert Cuellar, MD.
