Key Takeaways
- A subvastus knee replacement is a muscle-sparing procedure where the surgeon accesses the knee joint by lifting the quadriceps muscle instead of cutting through it.
- The traditional knee replacement approach involves an incision through the quadriceps tendon to expose the knee joint.
- Benefits of the subvastus approach can include a quicker recovery, less postoperative pain, and improved knee function compared to the traditional method.
- The best approach for you depends on factors like your knee anatomy, the extent of arthritis, and your surgeon's recommendation.

Understanding Your Knee Replacement Options
When knee pain from arthritis or an injury becomes too much to handle, a total knee replacement can bring significant relief and restore your quality of life. The procedure involves replacing the damaged surfaces of the knee joint with artificial implants. While the goal is always the same—a stable, pain-free knee—surgeons can use different techniques to get there.
Two common methods are the traditional approach and the subvastus approach. The main difference lies in how the surgeon accesses the knee joint, specifically how they manage the large quadriceps muscle group at the front of your thigh. Understanding these differences can help you have a more informed discussion with your surgeon about which option is best suited for your individual needs.
Dr. Haben incorporates innovative technology to enhance surgical precision. With ARVIS™, an advanced Augmented Reality Visualization and Information System, key anatomical landmarks are visualized in real time, enabling personalized implant positioning. Coupled with the EMPOWR 3D Knee™ by enovis™, designed to replicate the natural motion of the knee, these tools support improved stability and outcomes for patients.
Subvastus vs. Traditional Knee Replacement: A Detailed Comparison
The choice between a subvastus and a traditional knee replacement depends on several factors, including your anatomy and your surgeon's expertise. Dr. Collin Haben carefully evaluates each patient to determine the most effective and least invasive technique for their specific condition.
The Subvastus Approach: A Muscle-Sparing Technique
The subvastus knee replacement is considered a minimally invasive, tissue-sparing procedure. The key to this technique is avoiding an incision into the quadriceps tendon. Instead, the surgeon works around the quadriceps muscle group by lifting a section of it (the vastus medialis) out of the way to access the knee joint.
By preserving the quadriceps muscle and tendon, patients often experience several benefits:
- Less Pain: Because the major muscle group responsible for knee extension isn't cut, patients frequently report less pain after the operation.
- Faster Recovery: With the quadriceps intact, patients can often regain muscle control more quickly. Many can perform a straight leg raise on the same day as their surgery, a key milestone in early recovery.
- Improved Early Function: A quicker return of muscle function can lead to an easier time with physical therapy and a faster return to activities like walking and climbing stairs.
However, the subvastus approach is a more technically demanding procedure and may not be suitable for every patient. Factors like severe obesity, extensive scar tissue from previous surgeries, or significant knee deformity might make the traditional approach a better and safer choice.
The Traditional Approach: The Standard of Care
The traditional knee replacement, also known as the medial parapatellar approach, has been the gold standard for decades. It has a long and proven track record of success in relieving pain and restoring knee function.
In this procedure, the surgeon makes an incision in the front of the knee and cuts through a portion of the quadriceps tendon to move the kneecap aside. This provides excellent visibility of the entire knee joint, allowing the surgeon to precisely place the implants.
While this approach involves cutting the tendon, it is a highly reliable and versatile technique that can be used for nearly all patients, including those with complex knee problems. After the implants are in place, the surgeon carefully repairs the tendon. The recovery process may be slightly longer compared to the subvastus approach, as this tendon needs time to heal properly.

Frequently Asked Questions
What is the success rate of a subvastus knee replacement?
The subvastus approach has a high success rate, comparable to the traditional method, in properly selected patients. Long-term studies show excellent implant durability and patient satisfaction. Success often depends on the surgeon's skill and the patient's commitment to rehabilitation.
How long is the recovery for a subvastus knee replacement?
While recovery varies for each person, patients who undergo a subvastus knee replacement often have a faster initial recovery. They may walk with less assistance sooner and regain muscle strength more quickly than with a traditional approach. Full recovery, however, still takes several months of dedicated physical therapy.
Am I a good candidate for a subvastus knee replacement?
Good candidates for the subvastus approach are typically patients who are not morbidly obese and do not have severe knee deformities or extensive scarring from prior surgeries. Dr. Collin Haben will conduct a thorough evaluation of your anatomy and medical history to determine if this muscle-sparing technique is right for you.
Which knee replacement approach is better?
Neither approach is universally 'better'—the best one is what's right for the individual patient. The traditional approach is highly reliable for a broad range of cases, while the subvastus approach can offer a quicker initial recovery for suitable candidates. Your surgeon will recommend the best option based on your specific needs.
