  • I used Dr Sam Rajaratnam for my knee replacement operation and was more than pleased with him and the whole team that is around him. The care of the doctor and the team, quality of the operation and the support after I was home with the physio(Steve) that works closely with Dr Sam Rajaratnam was excellent and the team were checked in and ensured that everything was going well and I was improving week by week. Would not hesitate to recommend Dr Sam Rajaratnam and his team.
