Elective surgery refers to a procedure that is planned in advance and is not considered an emergency. Patients typically choose to undergo elective surgery to improve their quality of life, address a medical issue, or enhance their appearance. Examples include knee replacement, cosmetic surgery, and gallbladder removal. While elective surgeries are important for many patients, they are usually scheduled based on the patient's convenience and the surgeon's availability. These procedures can vary in complexity and recovery time, and patients often undergo pre-operative assessments to ensure they are fit for surgery.
