Partial Knee Replacement Surgey
At Northern Westchester Hospital, our orthopedic surgeons utilize leading-edge technology to enhance visualization, precision, and control when performing partial knee replacement surgery.
Millions of Americans suffer from the debilitating pain of osteoarthritis (OA) each day. As one of the leading causes for disability worldwide, OA is a degenerative joint disease resulting in the wearing and eventual loss of cartilage. Those suffering from OA often experience quality of life issues, loss of mobility, stiffness and swelling and joint pain.
Robot-assisted unicondylar knee surgery enables surgeons to perform partial knee replacements that can decrease pain and help patients return to daily activities. During the procedure, the diseased portion of the bone is replaced with an implant that spares healthy bone by only replacing the diseased area, thereby helping to return knee function.
Partial knee replacement surgery offers patients several benefits as compared to total knee arthroplasty:
- Less pain¹
- Quicker rehabilitation¹·²
- Smaller incisions³
- Preserves anterior (ACL) and posterior (PCL) cruciate ligament preservation
- Less bone loss
- Accurately placed implants
- No CT radiation required
- Customized planning from your knee
How does a Navio surgery work?
The Navio robot-assisted surgical system provides surgeons with the precision and control in bone resurfacing that only robot-assistance can provide. The Navio image-guided system and handheld instrumentation aids surgeons in providing precise surgical outcomes for patients living with knee pain caused by early to mid-stage osteoarthritis.
A Navio partial knee replacement surgery at Northern Westchester Hospital works much the same way a normal partial-knee replacement surgery works. There are no pre-operative procedures required. The difference is in the tools the surgeon uses. The Navio is a robot-assisted smart instrument that delivers robotic precision into the surgeon’s hands, allowing for controlled, accurate and predictable procedures.
The surgeon will re-create a model of your knee’s kinematics (movement) and bone anatomy using computer-assisted virtualization that doesn’t require input of a CT scan. Using this virtual model, the surgeon will plan the location of the implant and balance the knee through flexion (bending). Finally, using the Navio handpiece, the surgeon will prepare the bone to accept the implant.
