Subvastus Robotic Total Knee Arthroplasty
A Modern Approach to Knee Replacement
Knee arthritis can cause pain, stiffness, and loss of mobility that limits your daily life.
When conservative treatments are no longer effective, total knee replacement is often the best option. Advances in surgical technique and technology now allow for more precise, less invasive procedures.
At Oklahoma Surgical Hospital, I perform robotic-assisted total knee arthroplasty using the subvastus approach. This technique combines state-of-the-art robotics with a muscle-sparing incision to help patients recover faster and return to the activities they enjoy.
What Is the Subvastus Approach?
Traditional total knee replacement requires splitting the quadriceps tendon to access the joint. The subvastus approach carefully works underneath the vastus medialis muscle on the inside of the thigh, avoiding cutting through the quadriceps tendon.
By preserving the quadriceps mechanism, patients often experience:
Less pain immediately after surgery
Quicker return of muscle strength
Faster ability to walk without assistance
The Advantage of Robotic Technology
Robotic assistance allows for unmatched accuracy during total knee replacement.
With the ROSA robot, I can:
Plan your surgery precisely for your unique anatomy
Balance the ligaments and soft tissues around the knee more naturally
Position the implant with greater accuracy compared to traditional techniques
This precision leads to improved alignment and function of the new joint, which can enhance long-term outcomes.
Why Choose Subvastus Robotic Knee Replacement?
When the subvastus approach is combined with robotic assistance, patients often benefit from both less early discomfort and improved long-term function.
Together, these innovations provide:
Smaller incision with muscle preservation
Reduced need for postoperative pain medication
Faster rehabilitation and return to daily activities
Optimized implant fit and alignment for longevity of the knee replacement
My Philosophy
Every patient’s knee is unique, and so is every surgery. By combining advanced techniques like the subvastus approach with cutting-edge robotic guidance, my goal is to help you achieve the most natural-feeling, long-lasting result possible.
About
Scott E. Plaster, MD, was born and raised in Tulsa. OK. He received his undergraduate degree and medical degree at the University of Oklahoma, where he also met his wife. His undergraduate degree of Biomedical Engineering directed him to the mechanical principles of orthopedics, and specifically to the specialty of hip and knee reconstruction.
Dr. Plaster completed his orthopedic residency at the University of New Mexico where he was involved with several research and textbook publications. During residency, he and his wife had their set of twins who are his pride and joy.
He completed his Adult Reconstruction fellowship at Allegheny General Hospital in Pittsburgh, PA. specializing in muscle sparing direct anterior hip replacements, state-of-the-art robotic hip and knee replacements, as well as complex hip and knee revisions.
Dr. Plaster’s passion is giving patients their lives back by means of cutting-edge technology and evidence based joint replacement surgery. He believes in providing patient-specific care with efficient and cost-effective treatments. Dr. Plaster offers precision robotic hip and knee replacement, direct anterior hip replacement, partial knee replacement, and complex hip and knee revisions. His interests outside of work include being a father and husband, as well as playing golf. running, and exploring the great outdoors.
