Key Takeaways
- Muscle-sparing knee replacement is an advanced surgical technique designed to implant a new knee joint without cutting through the quadriceps tendon or major muscles.
- This approach typically results in less postoperative pain, a shorter hospital stay, and a quicker return to daily activities compared to traditional methods.
- By preserving the surrounding soft tissues, patients often experience a better range of motion and stability immediately after surgery.
- Not every patient is a candidate; eligibility depends on factors like anatomy, weight, and previous surgeries.

Understanding Muscle-Sparing Knee Replacement
For decades, knee replacement surgery has been a reliable solution for severe arthritis and joint damage. However, the traditional approach often involves cutting through the quadriceps tendon to access the joint. While effective, this trauma to the muscle requires significant healing time.
Muscle-sparing knee replacement changes the narrative. It is a specialized technique that allows surgeons to insert the artificial joint without slicing through the quadriceps muscle or tendon. Instead, the surgeon works around these vital tissues. By pushing the muscles to the side rather than cutting them, the structural integrity of the knee remains intact.
This method falls under the category of minimally invasive knee surgery. The goal isn't just to replace the joint but to do so with the least amount of disruption to the body's natural mechanics. Because the quadriceps muscle is the powerhouse for knee extension and walking, leaving it uncut means patients can often lift their leg and walk comfortably much sooner after the operation.
Dr. Haben utilizes advanced tools to enhance each procedure. One of these is ARVIS™, an Augmented Reality Visualization and Information System, which allows Dr. Haben to visualize key anatomical landmarks in real time during surgery. Using head movements or voice commands, ARVIS™ is fully controlled by the surgeon, allowing for more personalized implant positioning. Using the EMPOWR 3D Knee™ by Enovis™, which is designed to mimic the natural dual-pivot motion of the knee, Dr. Haben helps patients achieve more stable joints.
Muscle-Sparing vs. Traditional Knee Replacement: What’s the Difference?
To appreciate the value of this modern approach, it helps to understand the standard total knee replacement surgery procedure.
In a traditional total knee replacement, the surgeon makes a vertical incision over the center of the knee. To expose the joint, they must split the quadriceps tendon and turn the kneecap (patella) over. Once the new implant is in place, the tendon must be repaired. This cut is the primary reason recovery can be lengthy; the muscle must heal before it can strengthen.
In contrast, new knee replacement techniques like the muscle-sparing approach utilize a smaller incision and a different pathway to the joint. The surgeon enters the knee from the side or below the muscle (subvastus or midvastus approaches), preserving the connection between the muscle and the kneecap.
The Benefits of Minimally Invasive Knee Surgery
Choosing a muscle-sparing approach offers several distinct advantages for patients eager to get back on their feet. When you search for a 'knee specialist near me,' you are likely looking for someone who can offer these specific benefits to improve your quality of life.
- Reduced Pain and Reliance on Medication
Because the muscles are not cut, there is significantly less internal trauma. Patients typically report lower pain scores in the days and weeks following surgery. This reduction in pain often correlates with a decreased need for narcotic pain medication, lowering the risk of side effects associated with opioids. - Faster Return to Function
The quadriceps muscle is crucial for standing up, climbing stairs, and walking. Since this muscle remains intact, patients usually have immediate control over their leg function. Many patients can lift their leg straight up immediately after surgery—a milestone that can take weeks with traditional surgery. This allows for an accelerated physical therapy timeline. - Improved Range of Motion
Scar tissue is a natural part of healing, but deep scar tissue within cut muscles can restrict movement. By preserving the soft tissue, there is less scarring within the muscle mechanism itself, often leading to a more natural feeling knee and better long-term range of motion. - Shorter Hospital Stays
With less pain and better mobility, the medical necessity for a long hospital stay decreases. Many patients undergoing muscle-sparing knee replacement are discharged within 24 hours, and some eligible patients may even undergo the procedure on an outpatient basis.
Who Is a Good Candidate?
While the benefits are compelling, muscle-sparing surgery is technically demanding and may not be suitable for every patient. It requires a surgeon with specialized training and high-volume experience.
Generally, you might be a strong candidate if:
- You are not severely overweight (excess soft tissue can make the smaller incision difficult to work through).
- You do not have significant bone deformities that require extensive correction.
- You have not had previous major open knee surgeries that created excessive scar tissue.
- You have reasonable range of motion prior to surgery.
However, exclusion criteria are not absolute. Advancements in surgical instruments are making these new knee replacement techniques accessible to a wider range of patients. The best way to determine your eligibility is to schedule a consultation with an expert like Dr. Collin Haben. He can evaluate your specific anatomy and arthritis severity to recommend the safest and most effective approach for you.
Recovery Expectations and Outcomes
Recovery is often the biggest concern for patients facing joint replacement. With the muscle-sparing technique, the timeline is often compressed
Week 1-2: Most patients are walking with a cane or walker within hours of surgery. By the end of the first week, many are transitioning to walking without assistive devices inside their homes. Physical therapy focuses on gait training and range of motion.
Week 3-6: Patients typically resume driving (if surgery was on the left leg or they are off narcotics) and return to light work if they have sedentary jobs. The focus shifts to strengthening the leg. Because the muscle wasn't cut, 'lag' (the inability to lift the leg straight) is rarely an issue.
Long-Term Outcomes: Studies suggest that long-term implant survival rates for minimally invasive procedures are comparable to traditional surgeries when performed by experienced surgeons. The primary difference lies in the early rehabilitation phase. Patients tend to report high satisfaction rates because they feel 'normal' sooner.
It is important to remember that while the technique speeds up the initial phase, total healing still takes time. You must commit to your physical therapy regimen to maximize the benefits of the surgery.

Frequently Asked Questions
Is muscle-sparing knee replacement safer than traditional surgery?
Every surgery carries risks, but muscle-sparing knee replacement is generally considered as safe as traditional methods when performed by a skilled surgeon. It offers the added safety benefits of potentially lower blood loss and a reduced risk of blood clots due to faster mobilization after surgery.
How do I find a qualified knee specialist near me?
To find a qualified surgeon, look for orthopedic specialists who specifically mention 'minimally invasive' or 'quadriceps-sparing' techniques on their website. It is crucial to ask the surgeon about their volume of surgeries—surgeons who perform these procedures frequently tend to have better outcomes.
Does the smaller incision affect the longevity of the implant?
No. The implant used in minimally invasive knee surgery is typically the same durable device used in traditional surgery. The 'minimally invasive' part refers to how the surgeon accesses the joint, not the joint itself. As long as the components are aligned correctly—which is a priority for Dr. Haben—the implant should last just as long.
Will I need physical therapy after the procedure?
Yes, physical therapy is vital for a successful recovery, regardless of the surgical technique. However, because the total knee replacement surgery procedure was muscle-sparing, you may progress through your therapy exercises faster and experience less soreness during sessions.
Is this procedure covered by insurance?
Generally, yes. Insurance providers typically cover knee replacement surgery based on medical necessity (arthritis, pain, loss of function) rather than the specific surgical technique used. Our office can help you verify your benefits and coverage prior to surgery.
