Muscle-Sparing (Quadriceps-Sparing) Knee Replacement
At Desert Orthopaedic Center, we’re committed to offering advanced care for all of your replacement needs. Continuing this effort, board-certified, fellowship-trained orthopaedic surgeon Dr. Steven Nishiyama specializes in muscle-sparing (quadriceps-sparing) knee replacement by utilizing our state-of-the-art CORI◊ Surgical System.
What Is Muscle-Sparing Knee Replacement?
Muscle-sparing knee replacement is an advanced surgical technique designed to minimize tissue disruption, leading to faster recovery times and improved outcomes for patients suffering from knee joint issues.
Compared to traditional total knee replacement, muscle-sparing knee replacement offers:
- Less postoperative swelling and bruising
- Less postoperative pain
- Easier postoperative rehabilitation
- Faster return to unassisted walking and daily activities
- Shorter recovery period
- Quicker return to driving and work

Advantages of the CORI◊ Surgical System
The CORI◊ Surgical System is a handheld robotics-assisted platform that enhances the accuracy of knee replacement procedures. Unlike traditional methods, the CORI◊ system does not require preoperative CT scans or MRIs. Instead, it creates a real-time 3D digital model of your knee during surgery.
Combining the muscle-sparing approach with the CORI◊ Surgical System, Dr. Nishiyama offers a minimally invasive and highly precise treatment designed to improve surgical outcomes and speed up recovery.
Is Muscle-Sparing Knee Replacement Right for You?
If you are experiencing knee pain or discomfort from arthritis, past injuries, or other joint conditions, muscle-sparing knee replacement may be an effective treatment to help relieve your pain and regain your strength.
