Joint Replacement Surgery, also known as Arthroplasty, is a procedure in which a damaged or worn-out joint is removed and replaced with an artificial implant called a prosthesis. The prosthesis is designed to replicate the natural movement of a healthy joint — eliminating pain and restoring function.

This surgery is most commonly performed on the knee and hip joints, but can also be done on the shoulder, elbow, and ankle. It is one of the most successful surgical procedures in orthopaedics, with high success rates and long-lasting results.
