The Subvastus Approach in Knee Replacement

A Smarter Approach to Total Knee Replacement

If you’re preparing for knee replacement surgery, your goal is simple—getting back to your life quickly, comfortably, and with lasting results. At Sierra Pacific Orthopedics, Dr. Henry Dunn performs knee replacement using the subvastus approach, a modern, muscle-sparing technique designed to minimize pain and shorten recovery time. This approach represents the next evolution in personalized knee replacement care.

Understanding the Subvastus Approach

Traditional knee replacement is often performed through a medial parapatellar or midvastus approach, which involves cutting the quadriceps tendon or the vastus medialis muscle. In contrast, the subvastus approach allows access to the knee joint by going beneath the quadriceps muscle—preserving both the tendon and surrounding muscle. Because no muscle is cut, there is typically less trauma, less postoperative pain, and a faster return to function. These early benefits often lead to a smoother recovery in the months that follow.

How This Technique Differs From Traditional Methods

The subvastus approach focuses on preserving muscle and soft tissue. By reducing tissue disruption and avoiding the use of a tourniquet, it minimizes ischemia—a temporary reduction of blood flow to tissues that can cause discomfort and slow recovery. This technique also limits the need for extensive ligament releases during surgery. Combined with our carefully structured preparation and recovery pathways, this method supports quicker healing and improved early motion compared to older surgical approaches.

Benefits of Minimally Invasive, Muscle-Sparing Surgery

• Maintains ligament integrity through robotic precision and accuracy
• Preserves muscles by avoiding any cuts to the quadriceps
• Less pain, faster recovery, and improved early quadriceps function

Who Is a Candidate?

Most patients—up to 99%—can have a total knee replacement using the subvastus approach. However, your specific needs and anatomy will help determine whether this technique is the best fit. Dr. Dunn will discuss all surgical options with you to ensure the safest and most effective plan for your knee replacement.

What to Expect for Recovery

Patients typically stand and begin walking on the day of surgery and progress off assistive devices within a few weeks. Noticeable improvement is often seen early in recovery, with most patients returning to daily activities within two to three months. While it’s natural to feel better as healing continues, pacing your activity is key to long-term success.

Risks & Considerations

Because the subvastus approach uses a smaller, less invasive incision and spares the surrounding muscles, it requires specialized instruments and a high level of surgical expertise. When performed by an experienced surgeon, the technique can help reduce potential risks and support a smoother recovery.

Is Recovery Less Painful?

Yes. Research shows that patients undergoing total knee replacement with the subvastus approach generally experience less postoperative pain and a reduced need for opioid medications compared to those treated with traditional methods.
