Rana Robotic Knee Replacement
Knee arthritis can make even simple activities painful — walking, climbing stairs, exercising, traveling, or simply getting through the day comfortably. When conservative treatments no longer provide relief, knee replacement surgery can help restore mobility, function, and quality of life.
At Dr. Sumit Rana, MD, every knee replacement is personalized to the individual patient. Dr. Rana combines advanced robotic-assisted technology, modern alignment principles, muscle-sparing surgical techniques, and state-of-the-art implants to help patients recover faster, move more naturally, and achieve excellent long-term outcomes.
As a Board-Certified, Fellowship-Trained Orthopedic Surgeon specializing in hip and knee replacement surgery, Dr. Rana utilizes the latest innovations in robotic-assisted knee replacement to provide highly individualized care tailored to each patient’s anatomy and goals.
What Is Robotic-Assisted Knee Replacement?
Robotic-assisted knee replacement is an advanced form of knee replacement surgery that allows for an extremely precise and personalized procedure.
During surgery, Dr. Rana utilizes advanced robotic-assisted technology to create a highly detailed, real-time map of the patient’s knee anatomy directly in the operating room. Unlike some robotic systems that require a pre-operative CT scan, this technology allows precise mapping and balancing of the knee during surgery without exposing patients to unnecessary additional radiation.
The robotic technology assists Dr. Rana in making highly accurate bone cuts, evaluating soft tissue balance, and fine-tuning implant positioning in real time. This level of precision helps create a knee replacement customized to each patient’s unique anatomy and movement patterns.
Importantly, the robot does not perform the surgery on its own. Dr. Rana remains fully in control throughout the procedure, using robotic technology as an advanced tool to enhance precision, accuracy, and consistency.
Personalized Knee Replacement Using Modern Alignment Principles
Dr. Rana incorporates modern individualized alignment principles into many of his robotic knee replacement procedures.Rather than forcing every patient’s knee into the same standardized alignment, this personalized approach aims to better recreate each patient’s natural anatomy and soft tissue balance whenever appropriate.This individualized philosophy may help patients experience:
- A more natural-feeling knee
- Improved knee motion
- Better soft tissue balance
- Greater comfort during activities
- Improved overall function and satisfaction after surgery
Combined with robotic precision, these techniques allow Dr. Rana to customize each knee replacement to the individual patient rather than using a “one-size-fits-all” approach.
Benefits of Rana Robotic Knee Replacement
Greater Precision
Advanced robotic-assisted technology allows Dr. Rana to make highly accurate adjustments during surgery with real-time feedback. Precise implant positioning and balancing may improve both function and long-term performance of the knee replacement.
Muscle- and Tendon-Sparing Techniques
Dr. Rana frequently utilizes advanced soft tissue–sparing approaches, including the subvastus approach, which works around the quadriceps tendon and muscle rather than cutting through them whenever possible.
By minimizing trauma to the surrounding tissues, many patients experience:
- Less post-operative pain
- Faster recovery
- Earlier return of function
- Improved early mobility
Faster Recovery
Modern pain management protocols, minimally invasive techniques, robotic precision, and outpatient surgery pathways help many patients recover more quickly and return home the same day as surgery.
Many patients begin walking within hours of their procedure.
More Natural Knee Function
Because robotic technology allows for individualized planning and balancing, many patients report that their knee feels more stable, smoother, and more natural during daily activities.
Reduced Radiation Exposure
Unlike some robotic systems that require a pre-operative CT scan, Dr. Rana utilizes technology that maps and balances the knee during surgery without exposing patients to unnecessary additional radiation.
Modern Implant Technology
Dr. Rana utilizes advanced modern knee replacement implant systems designed to improve knee motion, stability, durability, and overall patient satisfaction.
Combined with robotic-assisted precision and personalized alignment techniques, these implants help create a stable and natural-feeling knee replacement tailored to each patient.
Focus on Longevity & Implant Fixation
One of Dr. Rana’s goals during knee replacement surgery is to create a stable, durable knee replacement designed to last for many years.
Because robotic-assisted surgery allows for extremely precise bone preparation and implant positioning, Dr. Rana is able to utilize modern cementless press-fit fixation in the vast majority of appropriate patients.
Press-fit implants are designed to allow the patient’s own bone to grow directly into the implant surface, creating long-term biologic fixation without the use of cement.
Potential advantages of press-fit fixation may include:
- Long-term biologic bone integration
- Reduced risk of implant loosening over time
- Preservation of bone quality
- Excellent long-term durability
- Potentially easier revision surgery if ever needed in the future
Dr. Rana is able to perform cementless press-fit knee replacement in approximately 95% or more of his patients due to the precision provided by robotic-assisted surgery and modern surgical techniques.
