About Me

Dr. Jai Thilak Kailathuvalapil did his MBBS in 1988, Diploma in Orthopaedics in 1991. He completed his Masters in Orthopaedic Surgery in 1994. He also did his MCh Orthopaedic Surgery from University of Dundee, UK in 1999. His clinical fellowship training was in Arthroscopy and joint replacement surgery at National University Hospital (ISAKOS approved), Singapore in 2000. The APOA (Asia Pacific Orthopaedic Association) Fellowship with Dr. John Bartlett at Melbourne, Australia was in 2004. Recently, he was certified for Robotic Arm-assisted Joint Replacement Surgery by the MAKO training programme in the US. He was honored with FRCS membership from the Royal College of Physicians & Surgeons of Glasgow.
In 2000, he joined Amrita Institute of Medical Sciences, Kochi, India, as Senior Specialist. He had the privilege for being in the team, which started the orthopaedic department & the teaching unit. The main focus of the practice was in joint replacement surgery of the knee and hip and arthroscopic surgery of the knee & shoulder. Since the last 20 years in this hospital, he has been privileged to do more that 4000 joint replacement surgeries and 5000 arthroscopic surgery mainly of the knee, hip & shoulder. From 2017, he has pioneered the MAKO Robotic Arm-assisted Joint Replacement Surgery which is the first of its kind in India.

Research Activities

The aim in Amrita Institute of Medical Sciences is to undertake clinical & basic research at a level of national excellence since we have a large volume of patients with joint problems and has to undertake more than 600 major surgeries of joint replacement surgery & arthroscopy annually. Academics involve teaching undergraduates and postgraduate students. He is the director of the Fellowship programme in Adult Reconstruction in Amrita Hospital and was instrumental in getting the institute ISAKOS approved.
He has researched the morphometric measurements of the distal end of the femur of our patients undergoing total knee replacement for the betterment of the future generation of knee implants, currently studying the rotational axis of the distal femur and proximal tibia in knee replacement patients.
A cadaveric study was done on the anterolateral ligament of the knee which is a controversial topic among the sports medicine surgeons. Also did a study on the pattern of infective pathogens of the prosthetic joint infections in a tertiary care institute. He is also keenly researching & collecting the data of the PROMs (Patient Reported Outcome Measures) of the joint replacement surgeries to better understand the patient’s perspective of the surgery.
Privileged to start the first Mako Robotic Arm assisted surgery for joint replacement in the institute in July 2017. Amrita is the first Institute in India to get the MAKO Robot and we have initiated a study of evaluating the Robotic vs Jig-based knee arthroplasty patients. The joint replacement programme in Amrita was audited and modified from an average inpatient stay of 7 days to the current 3 days after the report. The commonest bacteria involved in prosthetic joint infection was audited and given an insight to the surgeon and the infectious disease specialist for better treatment protocols.
