Indian Innovation in Knee Replacement Earns Global Recognition
Chennai, India – Dr. Ragunanthan Narayanaswamy, Founder and Chief Orthopaedic Surgeon of Rathimed Speciality Hospital, has been invited to present his indigenous innovation in personalized knee replacement at the prestigious Personalized Arthroplasty Society (PAS) Annual Meeting in Montreal, Canada. This recognition reflects the growing global acknowledgement of an Indian breakthrough in personalized knee replacement.
Dr. Narayanaswamy’s innovation is the result of years of clinical experience, scientific research, and a commitment to solving real-world challenges. The hospital’s journey into kinematic knee replacement began in 2016, inspired by the work of Dr. Stephen Howell, who emphasized restoring a patient’s natural knee anatomy instead of relying solely on conventional mechanical alignment.
However, Indian patients presented a unique challenge, often seeking treatment only after advanced arthritis had resulted in severe deformity and bone loss. To address this, Dr. Narayanaswamy and his team developed precision surgical instruments that accurately recreate the patient’s original joint surface, enabling highly precise implant positioning in all three dimensions.
This “Make in India” breakthrough has shown encouraging outcomes, with patients experiencing reduced pain, less blood loss, faster rehabilitation, and improved functional mobility compared to conventional approaches. The technique aims to deliver a knee that feels and functions more naturally after surgery.
Dr. Narayanaswamy stated, “When we introduced kinematic knee replacement in 2016, many questioned the approach because it challenged conventional thinking. But we believed in the philosophy. As we continued, we saw patients recover faster, experience less pain and blood loss, and achieve better functional outcomes. Every innovation we pursue has only one purpose – to help our patients regain mobility and quality of life.”
The hospital is now training orthopaedic surgeons in personalized kinematic knee replacement and making its indigenous instruments available for wider adoption. This innovation has evolved from addressing a uniquely Indian clinical challenge to receiving international recognition, demonstrating the potential of Indian clinical expertise to contribute to the future of orthopaedic surgery worldwide.
Dr. Narayanaswamy’s presentation at the PAS Annual Meeting will showcase his indigenous surgical innovation, which has also been accepted for presentation at an international arthroplasty conference in China later this year.
