Chronic knee pain can impact your daily life, making even the simplest activities feel impossible. For severe arthritis or joint damage, knee replacement is often the best solution. However, many avoid surgery due to concerns about long recovery times and pain.
Thankfully, muscle-sparing knee replacement offers a modern, minimally invasive alternative. This technique preserves healthy tissue, speeds up recovery, and reduces post-operative pain, allowing patients to return to their lives sooner.
Key Takeaways
- Preserves Healthy Tissue: No cutting through the quadriceps tendon means less trauma and quicker healing.
- Faster Recovery Time: Patients often resume walking and driving sooner.
- Less Post-Op Pain: Reduced muscle damage means less swelling and less reliance on pain medication.
- Enhanced Precision with Advanced Tools: Dr. Collin Haben uses cutting-edge technology like ARVIS™ (Augmented Reality Visualization and Information System) to visualize key anatomical landmarks during surgery. ARVIS™ provides real-time guidance, controlled by head movements or voice commands, ensuring precise implant placement. Additionally, the EMPOWR 3D Knee™ by Enovis™, designed to mimic natural knee motion, enhances stability and function. Schedule your appointment today.
What Is Muscle-Sparing Knee Replacement?
To understand why this procedure is revolutionary, it helps to understand how traditional knee replacement works. In a standard total knee arthroplasty, the surgeon typically makes a long incision and cuts through the quadriceps tendon—the major muscle group on the front of the thigh—to access the knee joint. Once the implant is in place, that tendon must be repaired. This cutting and repairing process is a significant factor in the pain and length of recovery associated with knee surgery.
Muscle-sparing knee replacement (often referred to as quadriceps-sparing or subvastus approaches) takes a different path. Instead of cutting through the muscle, the surgeon navigates around it or lifts it to access the joint. Because the muscle fibers remain intact, the knee retains its strength and stability immediately after the procedure.
The Science Behind the Technique
The goal is anatomical preservation. By using specialized instruments and smaller incisions, Dr. Collin Haben can replace the damaged joint surfaces with the same high-quality implants used in traditional surgery, but without the collateral damage to the surrounding soft tissues. This requires a high degree of surgical skill and precision, making it essential to choose a specialist experienced in minimally invasive techniques.
Advantages of Minimally Invasive Knee Surgery
Patients who undergo muscle-sparing procedures often report a significantly different recovery experience compared to those who have traditional surgery. The benefits extend beyond just the timeline of healing.
Immediate Functional Strength
Because the quadriceps muscle is not severed, patients usually have better control of their leg immediately upon waking up. This muscle control is vital for walking without a limp and regaining independence quickly. Many patients are able to walk without assistive devices, such as walkers or canes, much sooner than expected.
Reduced Pain and Medication Use
Trauma to the muscle is a primary source of pain after orthopedic surgery. By sparing the muscle, the body experiences less inflammation and swelling. Consequently, patients often require fewer narcotic pain medications and can transition to over-the-counter pain relievers faster.
Improved Range of Motion
Scar tissue can inhibit movement. Since muscle-sparing incisions are smaller and the muscle is not repaired with sutures, there is typically less internal scarring. This allows for a more natural range of motion and makes physical therapy less grueling.
Traditional vs. Muscle-Sparing: A Comparison
When weighing your options, it is helpful to see the differences side-by-side. The following table outlines the general distinctions between the two surgical approaches.
| Feature | Traditional Knee Replacement | Muscle-Sparing Knee Replacement |
|---|---|---|
| Incision Length | 8 to 12 inches | 3 to 5 inches |
| Muscle Treatment | Quadriceps tendon is cut and repaired | Quadriceps muscle is pushed aside/preserved |
| Hospital Stay | 3 to 5 days (typically) | 1 to 2 days (or outpatient) |
| Recovery Time | 3 to 6 months for full activity | 4 to 8 weeks for full activity |
| Post-Op Pain | Moderate to Severe | Mild to Moderate |
Note: Individual results vary based on overall health, weight, and adherence to physical therapy.
Who Is a Good Candidate?
While muscle-sparing knee replacement is highly effective, it may not be suitable for every patient. Ideal candidates are generally those who:
- Have severe osteoarthritis or rheumatoid arthritis.
- Have not found relief through conservative treatments like medication, injections, or physical therapy.
- Are in reasonable overall health.
- Are motivated to participate in rehabilitation.
Certain factors, such as severe joint deformity or previous knee surgeries, might require a traditional approach to ensure the best outcome. During a consultation, Dr. Collin Haben evaluates specific anatomical needs to determine the safest surgical plan.
Recovery and Rehabilitation
Even with a muscle-sparing approach, physical therapy remains a non-negotiable part of the healing process. However, the timeline is often accelerated.
- Weeks 1–2: Most patients are walking on the day of surgery. Physical therapy focuses on reducing swelling and activating the leg muscles.
- Weeks 3–4: Many patients return to driving and light daily activities.
- Weeks 6–8: A return to low-impact recreational activities, such as golf or cycling, is common.
Because the muscle remains intact, the 'lag' time usually spent waiting for the tendon to heal is eliminated, allowing rehabilitation to focus immediately on strengthening and conditioning.

Frequently Asked Questions
Is muscle-sparing knee replacement covered by insurance?
Yes, muscle-sparing knee replacement is generally covered by most major insurance providers, including Medicare, just like traditional knee replacement. Coverage depends on your specific plan and medical necessity. It is always recommended to verify benefits with your provider prior to surgery.
How long does the surgery take?
The procedure typically takes between one and two hours, similar to traditional knee replacement. However, because it is minimally invasive, the preparation and closing time may be shorter depending on the complexity of the case.
Will I need physical therapy after muscle-sparing surgery?
Yes, physical therapy is crucial for a successful outcome. While the recovery is faster and often less painful, strengthening the muscles around the new joint and improving flexibility is essential for long-term function and implant longevity.
How long do the implants last?
Modern knee implants are designed to be durable. Studies show that more than 90% of knee replacements are still functioning well 15 years after surgery. The lifespan of the implant depends on factors such as patient weight, activity level, and the surgical technique used.
