Mr. Rajaratnam has the following sub-speciality interests within Knee Surgery.

  • Joint Replacement Surgery

    Mr. Rajaratnam is internationally renowned as one of the leading knee surgeons in the U.K., having performed close to 4000 Knee Replacement operations over his career. He has championed the concept of "Rapid Recovery and Enhanced pain relief" following joint replacement surgery, and lectures internationally on the subject.

    He performs amongst the highest number of knee replacements each year on the UK National Joint Registration, (approximately 400 knee replacements annually) with excellent and transparent outcomes.

    The UK, National Joint Registry (the leading joint registry in the world) regularly publishes data on Consultant Specific Revision Rates, where any implant that has been revised due to a complication is logged and monitored.

    Mr. Rajaratnam has one of the lowest revision rates (ie. best results over the last 5 years) on the UK NJR as depicted by the following graph.

    He is an expert on the latest rapid recovery techniques following knee surgery, and has assembled a team of Intensive Care Consultants, Specialist Nurse Practitioners, Sports and Exercise Medicine Consultants and Physiotherapists to work together to achieve optimal results.

    The latest joint replacement techniques he performs include both partial and full surface replacements and innovative techniques in patient-specific 3D printed customised alignment methods for the accurate fitting of knee implants. He also has an interest in Robotic Surgery.

  • Soft Tissue Knee Injury

    Mr Rajaratnam is a fellowship trained Soft Tissue Knee surgeon and treats numerous professional and amateur sportsmen with soft tissue knee injuries. His clientele include Professional Footballers, Actors and high profile individuals. He has an interest in "day case ACL reconstructions", and performs approximately 100 ACL reconstructions each year, where patients are able to comfortably walk out of hospital within 6 hours of their operation. He is one of the chosen surgeons for the Professional Football Association (PFA) and is on the faculty of the Isokinetic FIFA Football Medicine Conference.

    He is excited about the advances in stem cell and biological solutions for treating appropriate cartilage defects in the knee but is very careful in selecting the appropriate patient for each new technique, so as to practice proven and transparent evidence based medicine.
