ABOUT THIS PROCEDURE
What Is MAKO Robotic Total Knee Replacement?
The Stryker MAKO robotic system is a state-of-the-art surgical platform that combines CT-based 3D imaging with a robotic arm to assist Dr. Weidner in performing total knee replacement with exceptional precision.
Before surgery, a detailed CT scan creates a personalized 3D model of your knee. Dr. Weidner uses this model to pre-plan every aspect of the surgery — implant size, position, and alignment — specific to your anatomy. During surgery, the robotic arm provides real-time guidance and haptic feedback to ensure the plan is executed precisely.
HOW IT WORKS
The MAKO Process: Step by Step
01
CT Scan & 3D Planning
A pre-operative CT scan creates a detailed 3D model of your specific knee anatomy. Dr. Weidner uses this to plan the exact implant size, position, and alignment before you enter the operating room.
02
Robotic-Assisted Surgery
During surgery, the MAKO robotic arm provides real-time guidance and haptic feedback — physically preventing Dr. Weidner from cutting outside the pre-planned boundaries for extraordinary accuracy.
03
Personalized Implant Placement
The result is an implant positioned with a level of precision not possible with traditional instruments — optimizing alignment, balance, and long-term function of your new knee.
WHY PATIENTS CHOOSE THIS
Benefits of MAKO Robotic Total Knee Replacement
🤖
Robotic Precision
The robotic arm guides the surgeon with accuracy beyond what's possible with traditional manual instruments.
⚡
Faster Recovery
More precise surgery means less trauma to surrounding tissue, contributing to quicker rehabilitation.
📐
Better Alignment
Optimal implant alignment reduces wear, improves function, and extends the life of the knee replacement.
🏆
Long-Lasting Results
Better positioning means the implant is designed to last - modern implants expected to perform for 20-30+ years.
😌
Less Pain
Studies show MAKO patients report less post-operative pain compared to traditional knee replacement
🎯
Personalized to Your Anatomy
No two knees are alike. MAKO creates a surgical plan based on your specific CT scan - not a generic template.
CANDIDACY
Am I a Candidate for MAKO Knee Replacement?
Almost all patients with knee arthritis who need a total knee replacement are excellent candidates for use of the MAKO robot. Dr. Weidner will evaluate your X-rays, anatomy, and overall health during your consultation to confirm the best approach for you.
You may be a candidate if:
-
You have knee arthritis causing significant pain or limited mobility
-
Non-surgical treatments are no longer providing relief
-
X-rays show significant joint deterioration
-
You want the fastest possible return to daily activities
-
Knee pain is waking you at night or causing trouble sleeping
Not sure if you're a candidate?
Schedule a consultation with Dr. Weidner. He will review your imaging and give you an honest assessment of your options - no pressure, no obligation

COMMON QUESTIONS
Frequently Asked Questions
Q: What is MAKO robotic knee replacement?
A: The MAKO system uses CT-based imaging and a robotic arm to assist Dr. Weidner in planning and executing total knee replacement with exceptional precision. It is associated with better alignment, less pain, and potentially longer implant life compared to traditional techniques.
Q: Is robotic surgery safer than traditional knee replacement?
A: MAKO robotic surgery is not replacing the surgeon — it is assisting the surgeon. Dr. Weidner is in complete control throughout the procedure. The robotic arm provides precision guidance and feedback that enhances accuracy beyond what traditional instruments allow.
Q: How long does MAKO total knee replacement surgery take?
A: The surgery typically takes 60–75 minutes. The CT-based pre-planning done before surgery actually makes the operating room process more efficient and predictable. Total time at the surgical facility, including preparation and recovery, is usually 4–6 hours. Outpatient patients may go home the same day.
Q: Will I need to stay in the hospital?
A: Many patients are eligible for outpatient (same-day) MAKO knee replacement, meaning they go home the day of surgery. Other patients stay one night at the hospital. Dr. Weidner will determine the appropriate setting based on your health, home situation, and preferences.
Q: When can I walk after MAKO total knee replacement?
A: Most patients are walking with a walker just hours after surgery. The goal is to be up and moving the same day. Most patients transition from a walker to a cane within a few days to 2 weeks, and many are walking without any assistive device by 3-4 weeks.
Q: When can I drive after MAKO knee replacement?
A: If your left knee was replaced and you drive an automatic vehicle, you may be able to drive as soon as 10 days. Right knee replacement patients typically return to driving at 2-3 weeks, once they can reliably perform an emergency stop. Dr. Weidner will advise you at your follow-up appointments.
Q: How long does it take to fully recover from MAKO knee replacement?
A: Most patients return to normal daily activities around 4 weeks. Full recovery — including the ability to participate in higher-impact activities — typically occurs between 6 and 12 months. Individual results vary based on age, overall health, and activity level.
Q: How long will my knee implant last?
A: Modern knee implants are designed to last 20+ years in most patients. Better implant positioning — which MAKO helps achieve — is one of the key factors in implant longevity..
Q: How do I schedule a hip replacement consultation with Dr. Weidner?
A: Call our office at 703-393-1667 or schedule online. Dr. Weidner sees patients at his Manassas, Gainesville, & Fair Oaks offices and serves patients from throughout Northern Virginia including Haymarket, Gainesville, Woodbridge, Warrenton, Centreville, & Fairfax.
