Muscle-Sparing Knee Replacement

If knee pain is limiting your quality of life, we are here to support you. Knee replacement surgery may be the best tool to help you find relief. We offer procedures using advanced, muscle-sparing techniques as well as traditional. Dr. Russell Stewart, an experienced joint replacement surgeon, offers muscle-sparing knee replacement. He will work with you to find the best method for your unique medical history. Read on to explore muscle-sparing knee replacement and how it might benefit you.

What is muscle-sparing knee replacement?

Muscle-sparing knee replacement focuses on preserving the body's natural anatomy during surgery. Surgeons cut the quadriceps tendon during traditional knee replacement surgery. This helps the surgeon move the kneecap to gain an unobstructed view of the joint. A muscle-sparing (subvastus) approach allows the surgeon to work around the quadriceps extensor mechanism instead of cutting through it.

The surgeon works between muscles to protect important soft tissues and limit trauma to surrounding structures in the knee. This tissue-preserving philosophy can help maintain more natural knee function. It also supports a smoother recovery experience.

There are a few goals to the muscle-sparing approach. First, relieving the patient's pain caused by arthritis or joint damage. Second, restoring the knee's mobility while respecting the body's natural mechanics. For many, these techniques represent a modern, less invasive option.

What are the potential benefits of muscle-sparing knee replacement?

Because muscle-sparing knee replacement minimizes disruption to healthy tissues, many patients may experience advantages compared to more traditional surgical approaches. Potential benefits can include:

Less trauma to the quadriceps and muscle insertion
Potential for reduced postoperative pain
Preserved patellar blood supply
Preserved natural motion of the kneecap ("patellar tracking")
Improved early mobility and function
Faster recovery and rehabilitation timelines
Greater preservation of natural knee movement and stability

Each patient's condition, anatomy and recovery are unique—outcomes can vary. A thorough evaluation with an orthopedic specialist can help determine whether a muscle-sparing approach is the right option for your individual needs. Dr. Stewart is committed to working with each patient to create a personalized treatment plan that helps you reach your goals.
