  • My entire experience has been exceptional. Most importantly the knee replacement has been successful. The team, superbly led by Mr Unnithan were incredible. They were friendly, caring and attentive. All was explained to me in terms I understood and I can actually say the entire experience, though daunting and with a recovery period ahead was better than I could have reasonably expected or even hoped for. A very safe, caring pair of hands from everyone and cutting edge technology. Simply the best

  • Mr Unnithan was exceptional from start to finish. Thorough, knowledgeable and reassuring, he took time to explain everything and ensure I made the right decision. When I had an unexpected complication after surgery, his care was outstanding—he made a point of seeing me at numerous dressing changes to ensure all was well. Always approachable and available to answer questions, I felt genuinely cared for. I couldn’t have chosen a better surgeon. Thank you!
