Revision surgery refers to a surgical procedure that is performed to correct or revise a previous surgical procedure that did not produce the desired outcome or has resulted in complications. This may involve correcting errors, improving outcomes, or addressing issues that have arisen following the initial surgery. Revision surgeries can be more complex and challenging than initial surgeries, as they may involve scar tissue, altered anatomy, or other factors that complicate the procedure. The goal of revision surgery is to improve the patient's health and quality of life by addressing issues that were not adequately resolved by the initial surgery.
