Rapid recovery and innovation
Mr Rajaratnam has championed the concept of 'rapid recovery and enhanced pain relief' following joint replacement surgery and lectures internationally on the subject. His latest innovations in this field have been carefully developed over his extensive career and include a shorter operating time, advanced surgical techniques, multimodal anaesthesia, the use of local anaesthetic infusions and elite rehabilitation.

Mr Rajaratnam has assembled a team of Intensive Care Consultants, Anaesthetists, Specialist Nurse Practitioners, Sports & Exercise Medicine Consultants and Physiotherapists to work together to reduce pain and discomfort after knee surgery.

The latest joint replacement techniques he performs include both partial and full replacements and the use of patient-specific 3D customised alignment methods for accurate fitting of knee implants when necessary.

He is also an international authority on robotic knee replacement surgery and the ROSA® Knee System (from Zimmerbiomet). Having successfully implemented the first comercially active ROSA® Knee System for robotically assisted knee replacement surgery in the UK in December 2020 at Schoen Clinic London, Mr Rajaratnam regularly trains other surgeons on this technique.

Treatment of soft tissue knee injury
Mr Rajaratnam is a fellowship-trained Soft Tissue Knee surgeon and treats numerous professional and amateur sportsmen and women with soft tissue knee injuries. His clientele includes professional footballers, actors and high profile individuals. He has an interest in day case ACL reconstructions, and has performed approximately 1000 ACL reconstructions over his career, 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 each year.

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.
