Doctors in Delhi have reported a first-of-its-kind knee replacement procedure that combines an active robotic surgical system with a non-metallic ceramic knee implant. The doctors described it as the world’s first active robot-assisted surgery involving a non-metallic/ceramic knee replacement.
The procedure combines advances in robotic surgery with an alternative implant material. 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 discussed the development at a press conference.
Unlike conventional knee replacements, which predominantly use metal components, the implant used in this procedure is made from ceramic/non-metallic material. The doctors discussed the differences between the implant materials, along with their potential advantages and limitations.
The active robotic system used during the surgery is designed to assist with key surgical steps and support sub-millimetre accuracy. According to the doctors, robotic assistance can help improve consistency in bone preparation and implant positioning.
“The integration of active robotic technology with non-metallic implants opens a new avenue in knee replacement surgery,” Bhattacharjee said.
The doctors emphasised that advances in implant materials need to be supported by greater surgical precision. Accurate bone preparation and implant positioning remain important aspects of successful joint replacement procedures.
“Precision in implant positioning is an important part of achieving a successful joint replacement,” the statement read.
The discussion also covered recent progress in robotic joint replacement, minimally invasive techniques and the potential role of advanced implant materials in the future of knee surgery.
The combination of active robotic technology and non-metallic implants represents a developing area in joint replacement surgery. As clinical experience with these technologies grows, further evidence will help establish their role in the next generation of knee replacement procedures.
