Robotic-Assisted
Total Knee Replacement
Robotic guidance allows careful planning and precise execution during knee replacement surgery. The technology helps tailor implant positioning to each patient’s anatomy while maintaining the surgeon’s control throughout the procedure.
Robotic-assisted knee replacement is designed to relieve arthritis pain, restore stability, and allow patients to return to daily activity with confidence.
Dr. Gill performs robotic-assisted knee replacement in Johnson City for patients across the Tri-Cities region of East Tennessee.
What Is Robotic-Assisted Knee Replacement?
Total knee replacement treats advanced knee arthritis by replacing the worn surfaces of the joint with metal and polyethylene implants.
Robotic assistance adds a layer of planning and precision. Before bone preparation begins, the knee’s alignment, cartilage wear, and ligament balance are assessed in detail. This allows implant positioning to be adjusted to optimize alignment and stability for long-term function.
The procedure is performed entirely by the surgeon, with robotic technology serving as an advanced tool to support accurate execution of the surgical plan.
Why Robotic-Assisted Knee Replacement?
Robotic guidance enhances the procedure by ensuring:
Personalized alignment based on each patient’s anatomy
Consistent bone preparation
Accurate implant positioning
Careful balancing of the knee throughout its range of motion
These factors contribute to a well-aligned, stable knee replacement designed for long-term durability.
Knee Replacment on X-Ray
Before
Advanced osteoarthritis in the knee with loss of joint space and abnormal alignment. This causes pain, inflammation, and stiffness.
After
Total knee replacement restores alignment and creates a smooth surface for pain-free activity.
Who Is a Candidate for Knee Replacement?
Knee replacement may be considered when arthritis significantly limits daily activity and non-surgical treatments no longer provide meaningful relief.
Advanced knee arthritis
Persistent pain with walking or climbing stairs
Stiffness that limits motion
Reduced ability to remain active
Limited improvement with injections, medications, or physical therapy
A consultation and imaging evaluation help determine whether knee replacement is appropriate and when surgery may be the next step.
Considering a knee replacement?
A consultation allows us to review imaging, discuss non-surgical options, and determine whether robotic-assisted knee replacement is appropriate for your condition and goals.

What to Expect
Preparation
Medical optimization, patient education, and a defined recovery plan help ensure readiness and support a smooth perioperative course.
Surgery
Robotic-assisted knee replacement is performed using digital planning and evidence-based protocols. Precise component positioning and soft-tissue preservation are priorities. Many patients undergo surgery in an outpatient setting with same-day discharge when appropriate.
Recovery
Mobilization begins the day of surgery. Structured rehabilitation and scheduled follow-up visits support steady improvement in pain, mobility, and function over the first several weeks.
Recovery Timeline
Day of Surgery
Walking begins within hours after knee replacement.
Weeks 1–2
Focus on mobility, wound care, and safe movement at home.
Weeks 2–6
Return to driving and activity as gait and confidence improve.
Weeks 6–12
Progression of strength and endurance. Return to work.
3+ Months
Return to higher-level activity as recovery matures.
1 Year
Strength, balance, and function fully established.
Clinical Outcomes
Results
Significant pain reduction
Improved mobility and daily function
High long-term patient satisfaction
Dependable performance over time
Smooth recovery for most patients with steady improvement during the first several weeks
Risks
Infection
Blood clots
Stiffness
Nerve injury
Fracture
Implant wear or loosening
Common Questions About Robotic Knee Replacement
-
Before surgery, treatment may include medications, physical therapy, injections, bracing, and activity modification. Knee replacement is considered when these measures no longer provide meaningful relief.
-
No. The surgery is performed entirely by the surgeon. The robotic system functions as a planning and guidance tool that provides measurements during the procedure to help position the implants accurately.
-
Both techniques aim to relieve arthritis pain and restore function. Robotic guidance adds additional planning and measurement tools that help refine implant alignment and ligament balance during surgery.
-
Most patients begin standing and walking with assistance within hours after surgery. Early movement helps reduce stiffness and supports recovery.
-
Recovery involves soreness and stiffness in the early weeks after surgery. Modern pain management strategies, early mobilization, and structured rehabilitation help most patients progress steadily as comfort and function improve.
-
Most patients begin walking shortly after surgery and gradually increase activity during the first several weeks. Strength and function continue improving for several months as the knee adapts to the new joint.
-
Physical therapy typically begins immediately after surgery and continues for about 6 weeks. The goal is to restore motion, strength, and confidence in the knee during daily activities.
-
In this practice the patella is not routinely resurfaced. Preserving the natural kneecap allows the joint to function normally while avoiding unnecessary bone removal. The decision can be individualized depending on the condition of the patella.
-
Modern knee replacements are designed for long-term durability. Many implants function well for 20 years or longer depending on factors such as alignment, activity level, weight, and overall health.
A structured evaluation helps determine whether surgery is appropriate and how to approach it safely.
