Mar Sleeva Medicity Palai offers robotic knee replacement surgery using the VELYS Robotic Assisted Solution by DePuy Synthes, the orthopaedic company of Johnson & Johnson. This state of the art system enhances our existing surgical capabilities, ensuring every procedure is performed with personalised precision for superior patient outcomes. The new robotic facility was formally blessed by H.E. Mar Joseph Kallarangatt, Bishop of the Eparchy of Palai.

The VELYS Advantage
The core advantage of the VELYS system lies in its ability to tailor every surgery to the unique anatomy of each patient. By providing surgeons with real time clinical data and utilising infrared cameras with optical trackers, the system ensures highly accurate bone resection and optimal implant positioning. VELYS works exclusively with the ATTUNE Knee System, one of the most advanced and widely trusted knee implant platforms in the world.
Personalised Precision
Surgery customised to your specific joint anatomy using real time intra operative data not pre set templates.
Enhanced Safety
Minimal blood loss, accurate implant positioning, and reduced soft tissue trauma through sub millimetre optical tracking.
Comfortable Healing
Significantly reduced post operative pain owing to precision bone resection and ligament balanced implant placement.
Rapid Rehabilitation
Faster recovery and a quicker return to daily life most patients begin guided mobilisation within days of surgery.
How the System Works
The surgeon remains in complete control throughout the procedure. The VELYS robot does not operate or move on its own it functions as a precise digital assistant that enhances the surgeon's skill with data driven accuracy. The system is CT free and imageless, eliminating the need for pre operative CT scans and reducing radiation exposure, preparation time, and cost. Advanced intra operative imaging and motion tracking technology provide live surgical insights personalised to each patient's knee anatomy.
A Legacy of Orthopaedic Excellence
The Department of Orthopaedics at Mar Sleeva Medicity Palai has successfully completed over 2,000 knee replacements, including a milestone of 11 robotic assisted knee replacements in a single day using two VELYS systems running in parallel. The department is also home to the first Arthroscopy Skill Lab in South India and pioneered the first Cartilage Bone Complex Transplantation in the region. Through the Chuvadu initiative, life changing joint replacement surgeries are extended to the underprivileged.

Frequently Asked Questions
What is VELYS Robotic Knee Replacement?+
VELYS is an advanced robotic assisted solution by DePuy Synthes (Johnson & Johnson) for total knee replacement surgery. It uses real time clinical data, infrared cameras, and optical trackers to deliver highly accurate bone resection and optimal implant positioning. At Mar Sleeva Medicity Palai, the system enables surgery customised to each patient's unique joint anatomy for superior outcomes.
How is VELYS robotic knee surgery different from traditional knee replacement?+
Traditional knee replacement relies on manual measurements and surgeon judgement alone. VELYS adds real time intra operative data and optical tracking, enabling personalised precision tailored to your anatomy. It is also a CT free, imageless system, eliminating the need for pre operative CT scans. This translates to minimal blood loss, more accurate implant positioning, reduced post operative pain, and faster rehabilitation compared to conventional techniques.
What are the main benefits of VELYS robotic knee replacement?+
The four core benefits are personalised precision (surgery customised to your joint anatomy using live data), enhanced safety (minimal blood loss and sub millimetre implant positioning), comfortable healing (significantly reduced post operative pain), and rapid rehabilitation (faster recovery and a quicker return to daily life).
Does the robot perform the surgery?+
No. The surgeon remains in complete control throughout the procedure. VELYS functions as a precise digital assistant that enhances the surgeon's expertise with data driven accuracy. Every decision, every cut, and every implant placement is controlled by the orthopaedic specialist the robot does not operate or move on its own.
Who is a candidate for VELYS robotic knee replacement?+
Patients with severe knee arthritis, osteoarthritis, rheumatoid arthritis, or post traumatic knee damage who require total knee replacement may be candidates for VELYS robotic surgery. The orthopaedic team at Mar Sleeva Medicity Palai will evaluate your condition through clinical examination and imaging to determine the best treatment option.
How long is the recovery after VELYS robotic knee replacement?+
Recovery is typically faster compared to conventional knee replacement because of reduced post operative pain and minimal soft tissue trauma. Most patients begin guided rehabilitation soon after surgery and progress to walking within days. Full functional recovery depends on individual factors and rehabilitation adherence.
Why choose Mar Sleeva Medicity Palai for robotic knee replacement?+
Mar Sleeva Medicity Palai has completed over 2,000 successful knee replacements and achieved a milestone of 11 robotic assisted knee replacements in a single day. The hospital hosts the first Arthroscopy Skill Lab in South India, pioneered the first Cartilage Bone Complex Transplantation in the region, and offers life changing surgeries to the underprivileged through the Chuvadu initiative. The experienced orthopaedic team combined with two VELYS robotic systems delivers advanced joint replacement care.
