Joint Replacement

Arthroplasty is an excellent surgery that has helped many patients restore their joint function and resolve their symptoms.  Arthroplasty is a minimally invasive surgery that is performed through very small incisions to evaluate and treat a variety of painful joint conditions.  One incision is used for inserting an arthroscope and the other incisions are used for inserting instruments to repair the damaged structures.  An arthroscope is a pencil-sized instrument that has a small lens and lighting system at its one end. The arthroscope magnifies and illuminates the structures inside the body with the light that is transmitted through fibre optics. It is attached to a television camera and the internal structures are seen on the television monitor. A variety of painful conditions can be treated using this technique.

Reverse total arthroplasty: Reverse total arthroplasty is an alternative surgery for patients who have torn their rotator cuffs and have developed severe arthritis or who have had a previous total shoulder replacement that has failed to relieve their pain.  Rotator cuff is the group of four tendons that join the head of the humerus (arm bone) to the deeper muscles and provides stability and mobility to the shoulder joint.

The surgery is done under regional or general anaesthesia. An incision is made over the affected shoulder to expose the shoulder joint.  In normal procedure, metal ball is placed at end of upper arm bone and the socket into the shoulder bone. However in a reverse arthroplasty, the metal ball is attached to the shoulder bone and the socket is placed at the end of the upper arm bone.  By switching the prosthetics, the patient will now be able to use their deltoid muscle, instead of the torn rotator cuff, to enable lifting of their arm. After the artificial components are implanted the joint capsule is stitched and the wound is closed.
