Knee resurfacing surgery is an alternative to knee replacement. Rather than replacing the whole joint with a prosthesis (an artificial joint), Knee resurfacing surgery only replaces the damaged parts of the knee (ie the worn out arthritic compartments). This restores the knee, creating a ‘normal’ feel, and avoids some of the complications associated with a knee replacement. This is particular suitable for patients who do not have any cartilage remaining on a portion(s) of their knee and offers the potential for the patient to return to a fairly high level of activity.
