Key Takeaways
- Knee replacement is typically recommended once conservative treatments like medication, injections, and physical therapy stop relieving arthritis pain.
- Robotic-assisted knee replacement uses real-time mapping of the patient’s knee anatomy to guide precise bone cuts and implant placement.
- Most patients go home the same day and can expect to walk one mile by four to six weeks and two miles by six to eight weeks after surgery.
- Dr. John Redmond has performed over 4,000 robotic knee replacements and has been certified in the technique since 2011.
- Dr. John Redmond brings that experience to patients throughout Jacksonville's Southside and Beaches communities. Request an appointment to find out if robotic knee replacement is right for you.
Signs It May Be Time to Move Beyond Conservative Treatment
Knee pain does not always call for surgery right away. Physical therapy, anti-inflammatory medication, weight management, and injections are usually the first line of treatment for arthritis-related knee pain. But for many patients, these measures eventually stop working as well as they once did.
According to the American Academy of Orthopaedic Surgeons, if nonsurgical treatments are no longer managing arthritis symptoms, total knee replacement may be worth considering. Signs that conservative care may no longer be enough include:
- Knee pain that interferes with walking, climbing stairs, or getting out of a chair
- Moderate to severe pain even while resting or trying to sleep
- Chronic swelling that does not respond to medication or injections
- Stiffness that limits how far you can bend or straighten the knee
- X-rays showing significant joint damage, most often from osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis
If several of these apply, a conversation with an orthopedic knee surgeon near you is a reasonable next step, even if you are not sure surgery is right for you yet.
How Robotic-Assisted Knee Replacement Works
Dr. Redmond uses robotic-assisted technology for both total and partial knee replacement. The goal of the technology is not to replace the surgeon's judgment, but to add a layer of precision that is difficult to achieve with traditional instruments alone. Here is how the process generally unfolds:
- The robotic system creates a personalized 3D model of the patient’s knee using measurements taken during surgery.
- During surgery, pins are placed in the tibia and femur so the robotic system can track the joint in real time.
- The robot measures ligament tension throughout the joint, helping Dr. Redmond fine-tune a personalized surgical plan.
- A robotic arm makes precise bone cuts on the femur and tibia, which helps reduce trauma to the surrounding soft tissue.
- A trial implant is placed and tested through a full range of motion before the final components are secured.
Every patient also receives an intraoperative pain block that manages discomfort for the first 24 to 48 hours without causing muscle weakness, which is part of why same-day outpatient surgery is possible for most patients. The procedure itself typically takes just over an hour.
Robotic-Assisted vs. Traditional Knee Replacement
| Robotic-Assisted Knee Replacement | Traditional Knee Replacement | |
|---|---|---|
| Surgical planning | Built from real-time anatomical data collected during the procedure. | Based on manual measurements and surgeon judgment during surgery |
| Precision | Robotic arm guides bone cuts based on real-time ligament tension | Bone cuts made with standard mechanical instruments |
| Soft tissue impact | Designed to reduce trauma to surrounding tissue | Can involve more disruption depending on technique |
| Typical recovery | Many patients walk the same day, with outpatient surgery common | Recovery timelines vary depending on approach and hospital protocol |
Total knee replacement, whether robotic-assisted or traditional, remains one of the most successful and commonly performed procedures in orthopedics, with more than 700,000 performed annually in the United States according to the American Academy of Orthopaedic Surgeons.
Total vs. Partial Knee Replacement
Not every patient needs the entire joint replaced. Dr. Redmond evaluates the extent of damage on imaging to determine which approach makes sense:
- Total knee replacement: The damaged surfaces of the entire knee joint are removed and replaced with artificial components. This is generally recommended when arthritis affects the whole joint.
- Partial knee replacement: Only the damaged compartment of the knee is replaced. This minimally invasive option is appropriate when arthritis is limited to one area of the joint.
Dr. Redmond also uses the subvastus approach for knee replacement, an advanced technique that preserves the quadriceps muscle by accessing the joint without cutting through it. This can lead to less post-operative pain, improved early stability, and a faster recovery compared to more traditional muscle-cutting approaches.
What to Expect Before, During, and After Surgery
Before surgery: Your surgeon reviews your knee and prepares the plan. During the procedure, the robotic system maps your anatomy and helps guide precise implant placement.
During surgery: Robotic navigation guides Dr. Redmond through precise bone cuts and implant placement, adjusted in real time based on your ligament tension and joint mechanics.
After surgery: Most patients go home the same day and begin walking almost immediately. Typical recovery milestones include walking one mile by four to six weeks and two miles by six to eight weeks, with continued improvement over the following months. Dr. Redmond and his team provide a structured recovery plan and follow-up schedule for every patient.
Frequently Asked Questions
What conditions lead to knee replacement surgery?
Knee replacement is most often recommended when arthritis has caused significant joint damage that no longer responds to conservative treatment. The most common causes are osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis following an injury.
Is robotic knee replacement better than traditional knee replacement?
Robotic-assisted knee replacement allows for a level of precision that is difficult to achieve with traditional techniques, since the system helps guide implant positioning and bone cuts based on each patient's specific anatomy. Dr. Redmond has performed robotic knee replacements since 2011, has published research on the technology, and has taught other surgeons how to use it.
How long does recovery from robotic knee replacement take?
Most patients go home the same day as surgery and begin walking right away. Many patients walk one mile by four to six weeks and two miles by six to eight weeks, with continued improvement over the following months as strength and range of motion return.
