What Makes Mr Rajaratnam’s Knee Replacements Different?


Experience and Excellent Outcomes


Mr Rajaratnam is one of the UK’s most experienced knee replacement surgeons, having performed over 5200 knee replacements over the last 15 years. He performs approximately 600 primary knee implants yearly with about 40 – 50 partial knee replacements and 40-50 revision knee replacements. He has an internationally recognised joint replacement practice.

He has amongst the lowest revision (failure) rates in the UK on the National Joint Registry over the past two decades.


Cumulative Gains


Mr Rajaratnam works with the concept of cumulative marginal gains that he applies to knee replacement surgery. Cumulative gains are where you make several small improvements to a process that, put together, make a big difference.

In conjunction with Dr Barry Phillips, his consultant anaesthetist, Mr Rajaratnam has developed elite pain-relieving protocols using a combination of anaesthetic techniques. These include deep sedation general anaesthetic techniques in conjunction with spinal anaesthetic and local anaesthetic infusions. And in combination, this enables you to recover with very little pain in the early stages post-surgery.


Rapid Recovery


Post-operative care is often shared with experienced physiotherapists within the community who visit you at home and use advanced physiotherapy techniques to achieve an early range of motion recovery after knee replacement surgery. Additional methods, such as cryotherapy (icing), can help you recover faster.


The cumulative marginal gains concept means that most people recover reliably on a faster timescale than they previously did and with less pain.


Most of Mr Rajaratnam’s patients can drive within 2-4 weeks and return to reasonably regular activity within about six weeks after knee replacement surgery. It is important to note that everyone is slightly different. While some people take longer to recover, others may recover faster. Everyone has their unique journey. Ultimately the aim is to enable not only a fast return to function but also less pain and better long-term satisfaction with your new knee.
