The Subvastus Approach with Mako Robotics: A Smarter Path to Knee Replacement
If you're considering a Total Knee Arthroplasty (TKA), your main goal is simple: to get back to your life with as little pain and recovery time as possible.
We offer a muscle-sparing surgical technique–the Subvastus Approach–that is a key component of our next generation of personalized knee replacement care. When combined with advanced tools like robotic assistance and kinematic alignment, this approach helps us minimize trauma and maximize your recovery.
What is the Subvastus Approach?
Traditional knee replacement techniques (like the medial parapatellar or midvastus approaches) often require cutting either the quadriceps tendon or a portion of the vastus medialis muscle to access the joint.
The Subvastus Approach is uniquely muscle-sparing. Instead of cutting, we access the joint by entering underneath the entire quadriceps muscle.
Key Benefits for Your Recovery
This muscle-sparing technique is designed to cause less trauma and pain in the critical early period following surgery. A better start to your recovery sets a positive stage for the months of rehabilitation that follow.
We use this approach alongside a modern protocol that includes:
- Minimizing Tissue Damage: By avoiding muscle cuts and often using a tourniquet-free technique, we reduce tissue ischemia (restricted blood flow) and the need for extensive tissue releases to balance the knee.
- Precision Tools: Utilizing robotic assistance ensures precise sizing and placement of your implant.
- Kinematic Alignment: This surgical philosophy aims to restore your knee to its unique pre-arthritic motion and function.
All these choices–the muscle-sparing approach, the advanced tools, and our dedicated prep and recovery pathway–combine to provide a better, more predictable knee replacement experience.
Frequently Asked Questions
Is Recovery Less Painful with the Subvastus Approach?
Yes. Studies have consistently shown that patients who undergo TKA with the Subvastus Approach experience a less painful recovery in the early postoperative period. Patients often require significantly fewer opioid pain medications compared to those undergoing traditional approaches.
What is the Recovery Time?
While every patient is unique, this approach often allows for a faster initial recovery:
- Day of Surgery: Patients typically walk and complete stairs.
- First Few Days: Most patients are able to get off assistive devices around the home (like walkers or canes).
- Within a Few Weeks: You will see marked daily improvements.
- By 2-3 Months: Patients are typically back to almost all their regular activities.
What are the Risks?
Because the Subvastus Approach involves accessing the joint through a smaller, less invasive window, it requires specialized tools and a high level of surgical skill. Our expertise in this advanced technique ensures we minimize any potential risks associated with the smaller approach.
Am I a Good Candidate for the Subvastus Approach?
While a large majority of patients are candidates for a Subvastus Approach, the best surgical plan is always decided together with your physician. We will thoroughly review your medical history, imaging, and specific needs to determine the approach that is best for you.
