Delhi Doctors Combine Active Robotics With Ceramic Implant in Knee Replacement First

Doctors in Delhi have carried out a knee replacement that pairs an active robotic surgical system with a non-metallic ceramic implant, a combination they described as a first-of-its-kind procedure and one that could point to a new direction in joint replacement surgery.

The surgery was performed with active robotic assistance and was presented by the doctors as the world's first active robot-assisted knee replacement involving a non-metallic or ceramic implant, according to a statement issued on Wednesday.

Dr Sujoy Bhattacharjee, Chairman and Chief of the Max Institute of Robotic Joint Replacement at Max Super Speciality Hospital, Saket, and German orthopaedic surgeon Prof Dr Michael Wagner spoke about the procedure at a press conference in the national capital.

According to the doctors, the approach brings together two strands of medical advancement: newer implant materials and robotic surgery. The active robotic system, they said, helped achieve greater precision during the operation.

"The integration of active robotic technology with non-metallic implants opens a new avenue in knee replacement surgery," Bhattacharjee said in the statement.

Conventional knee replacements rely largely on metal components. The procedure in Delhi instead used a ceramic, non-metallic implant. The doctors discussed how the material differs from standard implants and the potential advantages and limitations that come with its use.

The robotic element is equally central. An active robotic system is designed to assist in carrying out surgical steps and to achieve sub-millimetre accuracy, the statement said. Bhattacharjee noted that the technology could improve consistency across procedures by allowing greater precision in bone preparation and implant positioning.

The doctors also stressed that advances in implant materials need to be matched by advances in surgical precision, describing accurate implant positioning as an important part of a successful joint replacement.

Their discussion also covered recent developments in robotic joint replacement, minimally invasive techniques and the future use of advanced implant materials in knee surgery.

The convergence of active robotics and non-metallic implants, the doctors said, could shape how the next generation of joint replacement procedures develops.
