Is it time for a total hip replacement?
When hip arthritis starts stealing your sleep, your walks and your independence, a total hip replacement can give them back. Mr Ashwin Unnithan is a Consultant Orthopaedic Surgeon specialising in hip and knee surgery, offering total hip replacement – including young total hip replacement – to patients across Wimbledon and the wider South-West London and Surrey area. At your consultation, he reviews your imaging with you and talks through every option, including non-surgical measures, so that surgery is only ever the right next step, not the only one.
With over ten years’ experience and a high surgical volume, Mr Unnithan offers both conventional and robotic-assisted total hip replacement techniques, using implants with excellent long-term registry evidence. If surgery is right for you, the procedure is planned around your own anatomy, activity level and lifestyle, not a one-size-fits-all template.
Updated for 2026 to reflect the latest National Joint Registry implant survivorship data and current NICE guidance on osteoarthritis management.

If two or more of these sound familiar, it is worth having an honest conversation about whether a total hip replacement is right for you
