Prashanth Hospitals Becomes City’s First To Successfully Heal 500 Patients withRobotic Knee Replacement Surgeries Using 4th Gen Velys Tech

● Dr. Arumugam S, who leads the hospital’s Orthopaedic robotic knee replacement
program, becomes one of India’s top five surgeons to cross 500 surgeries using the
advanced 4 th Gen Velys.
Chennai, 26 th June, 2025: In a major advancement for precision-led orthopaedic care, Prashanth
Hospitals—one of Chennai’s leading multi-specialty healthcare providers—has become the first in the
city to complete over 500 robotic knee replacement surgeries using the state-of-the-art 4 th
Generation Velys Robotic-Assisted System. This milestone comes at a critical time, as India faces an
arthritis epidemic, with over 100 million people affected by the condition. Leading this achievement is
Dr. Arumugam S, Senior Orthopaedic Surgeon and Joint Replacement Expert at Prashanth Hospitals,
who now ranks among the top five surgeons in India to cross the 500-surgery mark using the 4th Gen
Velys system.
Osteoarthritis, especially in the knees, has seen a sharp rise among people over 60 due to sedentary
lifestyles, obesity, and aging. According to the Indian Journal of Orthopaedics, knee arthritis in India is
15 times more prevalent than in Western nations — making precision-driven treatment essential. This
milestone by Prashanth Hospitals sets a new benchmark by enabling anatomically aligned, rotational
knee movements that closely mimic natural function—leading to shorter hospital stays, quicker
recovery, and patients walking within a day and regaining near-normal mobility in just a month.
Commenting on the occasion, Dr. Arumugam S, Senior Orthopaedic Surgeon and Joint Replacement
Expert at Prashanth Hospitals, said: “India is slowly becoming the arthritis capital of the world—much
like it is with diabetes. We’re now seeing younger patients, even in their early 50s, requiring knee
replacements. Watching them walk out pain-free within days is a powerful reminder of why this
advancement matters. Robotic technology has moved beyond the one-size-fits-all approach. It has
enabled me to do patient-specific alignment—something conventional techniques simply can’t
offer—resulting in more precise, personalized, and effective knee replacements. As someone who also
mentors surgeons across India and Southeast Asia in robotic joint replacement, it’s incredibly
rewarding to see how technology is transforming care at every level.”
Once affecting just 1 in 10 senior citizens, arthritis now impacts 3 to 4 out of every 10 Indians over the
age of 60—with severe cases increasingly seen in patients as young as their early 40s and 50s. This
surge is driven by sedentary lifestyles, obesity, lack of exercise, and prolonged hours of desk-bound
work. Women, notably, account for over 75% of the knee replacement cases at Prashanth Hospitals, a
trend consistent across the country. Reflecting the broader momentum, the adoption of robotic
systems is expanding rapidly—even in Tier 2 and Tier 3, marking a significant step toward more
accessible, precise, and patient-specific orthopaedic care.
Dr. Prashanth Krishna, Managing Director of Prashanth Hospitals, shared the broader vision behind
this technological advancement: “Being the city’s first to use the latest 4th Gen Velys Robot and
successfully complete over 500 robotic knee replacement surgeries marks a major milestone in our
commitment to advanced healthcare at Prashanth Hospitals. This is not just about numbers—it’s about
helping patients regain mobility and confidence through precision-driven care. Robotic-assisted surgery
enables us to replicate natural knee movement with exceptional accuracy, resulting in faster recovery
and better long-term outcomes. As robotic adoption grows across India, Prashanth Hospitals remains
one of the pioneers in integrating both Velys for orthopaedics and SSI Mantra for soft tissue surgeries,
making us one of the few centres in Tamil Nadu to offer multi-specialty robotic capabilities under one
roof. Our goal has always been to bring world-class innovation to Chennai, and this achievement
reflects our dedication to transforming lives through cutting-edge care.”
