About Mr Arjuna Imbuldeniya

Dr Arj Imbuldeniya is a Consultant Knee and Hip Surgeon with over 25 years' experience, and the founder of OrthoLongevity - a biology-first, surgery-last approach to joint health that integrates orthopaedic surgery, regenerative medicine, longevity thinking, and biological risk profiling.

Most joint pain does not require surgery. Up to 90% of his patients avoid an operation altogether - through precise diagnosis, targeted regenerative treatments, and personalised programmes addressing the full picture: tissue biology, inflammatory load, movement quality, posture, gait, nutrition, sleep, and stress. Those who do require surgery are biologically and mechanically optimised beforehand, and supported through joined-up rehabilitation afterwards.

He holds a substantive Consultant post at the Chelsea and Westminster NHS Foundation Trust - bringing together the rigour of a high-volume NHS practice with the depth and personalisation of elite private care.

His regenerative medicine practice includes high-dose PRP (platelet-rich plasma) programmes, hyaluronic acid, Arthrosamid hydrogel, and BMAC (bone marrow aspirate concentrate) delivered both intra-articular and intraosseous. These are deployed as part of a structured OrthoLongevity pathway - not as isolated procedures, but as part of a coordinated plan developed with a multidisciplinary team of physiotherapists, osteopaths, strength and conditioning coaches, nutritionists, sports physicians, radiologists, and anaesthetists.

When surgery is required, his specialist areas include advanced meniscal repair, cartilage transplantation using the Arthrex Autocart system and Agili-C scaffold, ACL reconstruction with particular expertise in female athletes requiring enhanced fixation security and high-risk revision cases, patella stabilisation, robotic-assisted partial and total knee replacement, and muscle-sparing Rottinger anterior hip replacement - the procedure of choice for younger, active adults with hip arthritis who need a rapid return to full function.

Dr Imbuldeniya reads medicine at St Bartholomew's and the Royal London Hospital Medical School, and completed postgraduate training at major London teaching hospitals, including The Royal London, Charing Cross, St Mary's, and Chelsea and Westminster. He undertook specialist fellowship training in Sydney at the Mater Hospital - the largest joint replacement centre in the Southern Hemisphere - and in Barcelona working with surgeons treating elite European athletes. He is a Fellow of the Royal College of Surgeons of England, holds a Masters in Global Health Policy from Imperial College London, and is a member of the British Orthopaedic Association, the British Knee Society, the British Hip Society, and the European Sports Knee Surgery Association.

He has been chosen for the NHS Clinical Entrepreneur Programme and a graduate of the BiteLabs HealthTech Fellowship, through which he is developing OrthoLongevity as a technology-enabled platform, combining clinical decision-making with predictive joint health assessment. He remains actively involved in teaching and examining at Imperial College London.

"I treat you as an individual. If I can keep you away from surgery - with your biology working properly, your movement corrected, and your strength where it needs to be - that is always the better outcome. The advice I give is exactly what I would give to someone I care about."
