Quad Sparing Knee Replacement
What Is Quad-Sparing Knee Replacement?
Quad-sparing knee replacement is a minimally invasive knee replacement technique that preserves the quadriceps muscle and tendon during surgery. Unlike traditional approaches, this method avoids cutting through the quadriceps, helping maintain muscle strength and improve early function after surgery while still providing effective joint replacement.
When Is Quad-Sparing Knee Replacement Recommended?
Quad-sparing knee replacement may be recommended for patients who:
- Have moderate to severe knee arthritis
- Experience chronic knee pain that limits daily activities
- Have not found relief from nonsurgical treatments such as medications or physical therapy
- Are in good overall health with adequate muscle strength
- Meet specific anatomical criteria suitable for this approach
How Is Quad-Sparing Knee Replacement Performed?
During the procedure, the surgeon accesses the knee joint through a smaller incision and works around the quadriceps muscle rather than cutting it. Specialized instruments are used to remove damaged cartilage and bone before placing the artificial knee components. The goal is to restore smooth joint movement while preserving surrounding muscles and soft tissues.
What to Expect During Recovery After Quad-Sparing Knee Replacement?
Most patients begin walking shortly after surgery, often the same day. Because the quadriceps muscle is preserved, patients may experience less pain, improved early mobility, and a faster return to daily activities. Physical therapy is an essential part of recovery to restore strength, flexibility, and knee function.
What Are the Risks of Quad-Sparing Knee Replacement?
While generally safe, potential risks include:
- Infection
- Blood clots
- Implant loosening or wear
- Nerve or blood vessel injury
- Stiffness or persistent pain
What Are the Benefits of Quad-Sparing Knee Replacement?
Potential benefits of this approach include:
- Preservation of quadriceps muscle strength
- Less postoperative pain
- Faster early recovery and mobility
- Shorter hospital stay
- Improved overall knee function
