Anatomic Total Shoulder Replacement (TSA)
Both the ball and socket of the arthritic shoulder are replaced with components that faithfully reproduce the natural joint anatomy — delivering reliable pain relief and smooth, powerful movement when the rotator cuff is intact.
What is Anatomic Total Shoulder Replacement (TSA)?
Anatomic total shoulder replacement (TSA) reproduces the geometry of the native glenohumeral joint — a metal ball on a humeral stem replicates the femoral head, and a polyethylene glenoid component resurfaces the socket. Because the mechanics mirror normal anatomy, the rotator cuff continues to function as the primary power source for movement. It is the operation of choice for primary glenohumeral osteoarthritis, post-traumatic arthritis, avascular necrosis, and certain inflammatory arthritides in patients with a preserved, functional rotator cuff. Dr. Sai Kishan performs anatomic TSA at Lux Hospitals for carefully evaluated patients in whom this design provides the best biological and mechanical environment for long-term implant function.
How the Procedure Works
Anaesthesia & Positioning
General anaesthesia with interscalene block for extended post-operative pain control; beach-chair position for the deltopectoral approach.
Deltopectoral Exposure
The standard anterior incision provides access through the deltopectoral interval; the subscapularis is released to expose the joint.
Humeral Head Resection & Stem Insertion
The humeral head is resected at the anatomic neck; the canal is prepared with broaches and the stem is trialled before final selection.
Glenoid Preparation & Component Fixation
The glenoid articular surface is removed; the polyethylene glenoid component is cemented in the correct version and inclination.
Head Assembly, Trial & Closure
The humeral head is assembled; stability and movement are confirmed; the subscapularis is repaired and the wound is closed in layers.
Outcomes
Who Needs This Treatment?
- →Dependable pain relief from advanced glenohumeral arthritis in a single procedure
- →Faithful reproduction of natural shoulder geometry for smooth, intuitive movement
- →The intact rotator cuff continues to provide powerful active shoulder function
- →High patient satisfaction — significant improvement in daily comfort and activity
- →Contemporary implant designs with proven 15–20 year durability data
- →Appropriate for active patients with preserved cuff function and adequate bone stock
Anatomic shoulder replacement respects what nature designed — when the rotator cuff is healthy, there is no better way to eliminate arthritis pain and restore a shoulder that moves the way the patient remembers it moving.
