What is robotic-assisted total knee replacement?

Robotic-assisted total knee replacement is an advanced surgical approach that uses a 3D model of your knee (created from a CT scan) and a robotic arm to help the orthopedic surgeon prepare the bone and place the knee implant with sub-millimeter precision. The surgeon is always in full control; the robotic arm acts as a precise guide based on your personalized plan.

How is robotic knee replacement different from traditional knee replacement?

Traditional knee replacement relies on manual alignment guides and the surgeon's eye, while robotic-assisted surgery uses a 3D CT-based plan and a robotic arm to execute that plan with high precision. This typically results in better-balanced implants, less soft-tissue trauma, and often a smoother recovery compared with conventional techniques.

Who is a good candidate for robotic-assisted knee replacement?

Most patients with advanced knee osteoarthritis, post-traumatic arthritis, or severe knee pain that has not improved with non-surgical treatment can be candidates. Dr. Feghhi will review your X-rays, medical history, and lifestyle goals during consultation to confirm whether robotic-assisted surgery is right for you.

How long does robotic total knee replacement surgery take?

The actual robotic-assisted procedure typically takes 60-90 minutes. Pre-operative planning, anesthesia, and recovery room time add to your total visit, but most patients are discharged home the same day.

Is recovery faster with robotic knee replacement?

Many patients experience a smoother early recovery because robotic precision preserves more healthy bone and soft tissue. However, full recovery still takes about 3-6 months, and commitment to physical therapy is essential for the best result.

How long does a robotic-assisted knee replacement last?

Modern knee implants, when placed accurately, can last 20+ years in many patients. The robotic-assisted technique aims to extend implant longevity by optimizing alignment, sizing, and soft-tissue balance beyond what is reliably achievable by hand.

Is robotic knee replacement covered by insurance?

In most cases, the total knee replacement portion of the procedure is covered by insurance. The robotic technology and 3D planning are surgical tools the surgeon uses; coverage is based on the procedure itself. Our office will verify your benefits and walk you through any out-of-pocket costs before scheduling.

What Is Robotic-Assisted Knee Replacement

Precision Knee Surgery With 3D Planning

Robotic-assisted total knee replacement is an advanced surgical technique that combines the skill of an experienced orthopedic surgeon with the precision of a robotic-arm and computer navigation. Before the procedure, a detailed 3D model of your knee is created from a CT scan, allowing Dr. Feghhi to plan implant size, alignment, and positioning down to the millimeter based on your specific anatomy.

During surgery, the robotic arm assists in preparing the bone and placing the implant exactly where planned, while preserving more healthy bone and soft tissue. The result is a better-balanced, more natural-feeling knee replacement with reduced postoperative pain and a smoother recovery than traditional techniques.

Who Benefits From Robotic Knee Replacement?

Robotic-assisted total knee replacement may be the right option if conservative treatments are no longer providing relief and knee pain is interfering with daily life.

Severe Osteoarthritis

Advanced knee osteoarthritis with bone-on-bone contact that has not improved with injections, physical therapy, or medications.

Failed Prior Knee Surgery

Patients with persistent pain after a previous knee arthroscopy or partial replacement who now require full replacement.

Difficulty With Daily Activities

Trouble walking, climbing stairs, or standing for long periods because of chronic knee pain, stiffness, or swelling.

Pain at Rest or at Night

Constant aching, throbbing, or stiffness that disturbs sleep and is no longer controlled with rest or medication.

Visible Knee Deformity

A noticeable bow-legged or knock-knee alignment caused by uneven cartilage wear that robotic technology can help correct.

Tried Conservative Care Without Relief

Patients who have exhausted physical therapy, injections, weight management, and medications and are ready for a definitive solution.

The Procedure

What to Expect During Robotic Knee Replacement

Dr. Feghhi performs robotic-assisted total knee replacement as an outpatient procedure at a fully accredited surgical center, allowing most patients to return home the same day.

Personalized 3D CT Scan Planning

Before surgery, a CT scan of your knee is used to create a detailed 3D model. Dr. Feghhi uses this model to select the correct implant size, optimize alignment, balance ligaments, and design a surgical plan tailored to your anatomy.

Anesthesia & Preparation

You will receive general anesthesia or a regional nerve block to keep you comfortable. A small tracking array is placed on your leg so the robotic system can monitor knee position in real time during surgery.

Robotic-Assisted Bone Preparation

Using the pre-operative plan, the robotic arm precisely guides the removal of damaged bone and cartilage. The robotic system creates a 3D safety boundary, ensuring only the planned area is resected while preserving healthy tissue.

Implant Placement & Balancing

The metal and polyethylene components are positioned exactly as planned. Dr. Feghhi fine-tunes ligament balance and alignment in real time using robotic feedback for the most stable, natural-feeling knee possible.

Closure, Recovery & Walking

The incision is closed, and you begin recovery in our post-operative suite. Most robotic knee replacement patients walk with assistance within hours of surgery and are discharged home the same day.

Procedure Quick Facts

Duration 60-90 minutes
Incision Single 4-6 inch incision
