Total Knee Replacement

A total knee replacement involves resurfacing the worn ends of the thigh bone, shin bone, and often the kneecap with artificial components, restoring smooth, pain-free movement to a joint significantly affected by osteoarthritis or injury.

It's typically considered once non-surgical treatment no longer provides meaningful relief from pain and reduced function.

Is It Right for You?

A total knee replacement is generally considered when arthritis affects multiple parts of the joint and is significantly limiting your daily life — persistent pain, reduced mobility, and disrupted sleep that haven't responded to physiotherapy, activity changes, or injections.

If your arthritis is confined to a single part of the knee, a partial knee replacement may be a more appropriate option and Mr George will assess which applies to you.

Surgery typically takes around one to two hours, often performed as a short in-patient stay or day case. Physiotherapy usually begins within hours of surgery, focusing on early movement to prevent stiffness - a particular priority for the knee compared with other joints.

Mr George offers robotic-assisted knee replacement using the VELYS™ system, which uses your individual knee anatomy to build a personalised surgical plan and supports greater precision in implant positioning during surgery.

Not every patient is automatically a candidate, and conventional technique remains entirely appropriate for many cases - read more about robotic-assisted knee replacement.
