Austin C. Nabet, DO, FAAOS, is a board-certified orthopedic surgeon specializing in muscle-sparing total knee replacement in Norfolk, Virginia. Using the subvastus muscle-sparing approach, Dr. Nabet focuses on preserving the quadriceps muscle and extensor mechanism, supporting a faster, more predictable early recovery as part of a Rapid Recovery Joint Replacement philosophy. Patients from Norfolk, Virginia Beach, Chesapeake, and the greater Hampton Roads area seek Dr. Nabet for advanced knee replacement care.
What is Subvastus Muscle-Sparing Total Knee Replacement?
Subvastus Muscle-Sparing Total Knee Replacement is an advanced technique that allows access to the knee joint without cutting or splitting the quadriceps tendon or muscle. By working beneath and around the vastus medialis muscle, critical structures responsible for strength, stability, and function are preserved—key factors in early recovery after knee replacement surgery.
Why “Muscle-Sparing” Matters for Rapid Recovery Knee Replacement
One of the strongest predictors of early recovery following knee replacement surgery is the amount of muscle and soft-tissue trauma created during surgery. By preserving the quadriceps mechanism, the subvastus approach may support earlier muscle activation, improved early walking and stair function, and a more predictable rehabilitation progression. These principles are central to Rapid Recovery Knee Replacement.
Anatomical Considerations for Subvastus Muscle-Sparing Total Knee Replacement
The vastus medialis obliquus (VMO) plays a key role in knee stability and patellar tracking. Preserving this muscle helps maintain the integrity of the extensor mechanism, supporting early postoperative strength and functional mobility.
Indications and Contraindications for Subvastus Muscle-Sparing Total Knee Replacement
Dr. Nabet has been performing muscle-sparing knee replacement surgery for many years. With appropriate surgical experience, the vast majority of primary total knee replacements can be safely performed using the subvastus approach. There are very few exceptions, which may include complex revision cases or rare situations involving severe
stiffness, deformity, or extensive prior scarring. Each patient is evaluated individually to determine the safest and most effective surgical approach.
Subvastus Muscle-Sparing Total Knee Replacement Procedure
- Incision: Medial incision with protection of the quadriceps muscle
- Muscle Preservation: Vastus medialis gently mobilized rather than cut
- Joint Preparation: Arthritic surfaces precisely prepared
- Implant Placement: Components positioned to restore alignment and stability
- Closure: Quadriceps and extensor mechanism remain intact
Advantages of the Subvastus Muscle-Sparing Approach
Potential advantages supporting Rapid Recovery Joint Replacement include:
- Reduced muscle disruption
- Preservation of quadriceps strength
- Improved early knee motion
- Earlier mobilization
- A more predictable early recovery experience
Outcomes of Subvastus Muscle-Sparing Total Knee Replacement
Clinical studies of muscle-sparing knee replacement techniques demonstrate improved early functional recovery for many patients, with long-term outcomes comparable to traditional approaches. Dr. Nabet is committed to providing advanced knee replacement care in Norfolk, Virginia, with an emphasis on safe surgery, efficient rehabilitation, and reliable recovery milestones for patients throughout Hampton Roads.
