Narayana Health City Leads the Way with Robotic-Assisted Knee Replacement with the World’s Smallest Customized Implant

Bangalore, 7th November 2024:

Narayana Health City has successfully performed a revolutionary Total Knee Replacement (TKR) on a patient with severe osteoarthritis and significant deformities. The complex procedure utilized state-of-the-art robotic-assisted technology combined with customizable implants, a cutting-edge approach that offers unparalleled precision and personalization.
The patient, suffering from dwarfism, had previously undergone surgery to lengthen his thigh bone. However, his short stature posed complex surgical challenges, compounding the severity of the degeneration and deformities.
Upon initial assessment, the patient exhibited limited knee function, persistent pain and atypical bone proportions that made standard knee implants unsuitable. Further thorough investigations, including X-rays, scanograms, and a detailed CT scan, revealed disproportionate distal femur dimensions that were too small for conventional prosthetics, underscoring the need for a highly customized approach.

“Managing this case required more than a standard implant; we needed to precisely match the patient’s unique bone structure,” explained Dr. Prashanth B N, Consultant Orthopaedics & Joint Replacement. “Using CT imaging and 3D modeling, we designed patient-specific implants that accurately replicated the natural condylar proportions and ensured precise rotational alignment, which is essential for joint stability and function.”
This advanced approach not only restored function to the knee but minimized complications associated with the patient’s complex anatomy.
Prof. Arun Ranganathan, Director & HOD, Orthopedics, Spine & Trauma, noted, “Our hospital is equipped to provide comprehensive orthopedic care, with a dedicated team and advanced solutions for complex cases like this, ensuring the best possible outcomes. Narayana Health City can deliver such outcomes time and again because of our expertise and collaborative approach.”

Dr. Abhinandan S Punit, Consultant Orthopaedics & Joint Replacement, added, “At Narayana Health City, we have the surgical expertise and cutting-edge joint replacement capabilities necessary to take on complex orthopedic cases and achieve successful, precise results for our patients.”
This unique case highlights the growing importance of patient-specific implants in treating advanced orthopedic conditions, particularly as knee osteoarthritis becomes more prevalent in patients with varied and challenging anatomies.
