Faced with the need for imminent knee surgery, I was fortunate in finding - almost at random - Mr David Allen at the Nuffield. I found him to be very approachable and most proactive in discussing the varoius options available to me. David was one of the first to offer a robot guided partial knee replacement to me, instead of a full replacement, with its less invasive surgery and quicker recovery times. This has worked very well and I was walking unaided within a few days after the operation. I particularly appreciated David Allen's clear and consultative approach both before and immediately after surgery followed by a number of timely follow up visits to see how my knee was progressing. In short I can highly recommend Mr David Allan, not only for his obvious surgical skills, but also for his excellent and helpful friendly manner in dealing with his patients.
