Total & Reverse Shoulder Arthroplasty by Dr. Hemendra Agrawal

Shoulder Replacement Surgery, or Shoulder Arthroplasty, is a surgical procedure that replaces the damaged surfaces of the shoulder joint with artificial prosthetic components. The shoulder is the most mobile joint in the human body — a ball-and-socket joint where the humeral head (ball of the upper arm bone) articulates with the glenoid (shallow socket of the shoulder blade). This extraordinary range of motion makes the shoulder vulnerable to arthritis, rotator cuff disease, and fractures that can severely impact function.
Dr. Hemendra Agrawal performs three types of shoulder replacement: Anatomic Total Shoulder Replacement (TSA) for patients with intact rotator cuffs, Reverse Total Shoulder Replacement (RTSA) for patients with rotator cuff deficiency or complex fractures, and Hemiarthroplasty (replacing only the ball) for select fracture cases. The choice of procedure depends on the patient's underlying diagnosis, rotator cuff integrity, bone quality, and functional goals.
Reverse Total Shoulder Replacement represents one of the most significant advances in shoulder surgery over the past two decades. By reversing the normal anatomy — placing the ball on the socket side and the socket on the ball side — this innovative design allows the deltoid muscle to compensate for a deficient rotator cuff, enabling patients to raise their arm overhead and perform daily activities that were previously impossible.
With modern surgical techniques, advanced implant designs, and structured rehabilitation protocols, shoulder replacement surgery provides predictable and lasting pain relief with significant functional improvement. Dr. Agrawal's comprehensive approach — from accurate diagnosis through personalized rehabilitation — ensures optimal outcomes for every shoulder patient.
When is this procedure recommended?
Glenohumeral osteoarthritis — progressive cartilage loss in the shoulder joint with bone-on-bone contact
Rotator cuff tear arthropathy — combination of massive rotator cuff tear and secondary arthritis (indication for reverse TSA)
Rheumatoid arthritis of the shoulder — autoimmune joint destruction with pain and progressive stiffness
Complex proximal humerus fractures — 3-part and 4-part fractures in elderly patients where fixation is not feasible
Avascular necrosis of the humeral head — bone death due to disrupted blood supply
Post-traumatic arthritis — following shoulder fractures, dislocations, or previous surgery
Failed previous shoulder surgery — rotator cuff repair failure, failed fracture fixation, or prior arthroplasty
Chronic shoulder dislocation with arthritis — irreducible dislocation with joint surface damage
A detailed walkthrough of the surgical process
Comprehensive shoulder examination, X-rays (AP in internal and external rotation, axillary, scapular Y views), CT scan with 3D reconstruction for surgical planning and glenoid assessment, MRI to evaluate rotator cuff integrity and muscle quality. Templating and pre-operative planning using patient-specific guides if available.
A 12-15 cm incision is made over the front of the shoulder following the deltopectoral groove. The deltoid and pectoralis major muscles are separated (no muscles are cut). The subscapularis tendon is managed with tenotomy or lesser tuberosity osteotomy for access to the joint.
The arthritic humeral head is removed with an oscillating saw at the anatomic neck. The humeral canal is prepared with progressive broaches. A trial humeral stem is placed to assess height, version (rotation), and offset. For anatomic TSA, a humeral head matching the patient's anatomy is selected. For reverse TSA, a humeral socket (glenosphere tray) is placed on the humeral side.
For anatomic TSA: The glenoid is prepared by removing cartilage and shaping the bone. A polyethylene glenoid component is cemented in place. For reverse TSA: A metal baseplate is secured to the glenoid with screws, and a metal glenosphere (ball) is attached to the baseplate. This reverses the normal ball-and-socket relationship, converting the shoulder mechanics to be deltoid-powered.
The final humeral and glenoid components are assembled, the joint is reduced, and stability is tested through a full range of motion. The subscapularis is repaired (for anatomic TSA) or left open (for some reverse TSA designs). The wound is closed in layers, and a sling is applied.
How this procedure transforms your life
Significant pain relief — 95% of patients experience substantial pain reduction
Improved range of motion — enabling overhead activities, reaching behind the back, and grooming
Restored shoulder function for daily activities — dressing, eating, bathing, and reaching
Reverse TSA allows arm elevation even without a functioning rotator cuff
Modern implant survival exceeding 90% at 10-15 years for anatomic TSA and 93% at 10 years for reverse TSA
Improved sleep — elimination of night pain that prevents restful sleep
Enhanced quality of life and independence in self-care activities
Alternative to living with chronic pain and progressive disability
What to expect during your recovery journey
Arm in sling for support and comfort. Gentle pendulum exercises and elbow/wrist/hand movements only. Ice therapy for swelling. Wound care and suture removal at 2 weeks.
Physiotherapist-guided passive range of motion exercises. Sling continued between exercises. Gentle passive forward elevation, external rotation. No active lifting.
Sling discontinued. Active-assisted progressing to active range of motion. Light isometric strengthening. Return to desk work and driving. Gradually increasing daily activities.
Progressive strengthening of shoulder muscles — deltoid, rotator cuff (if intact), periscapular muscles. Resistance band exercises. Light recreational activities.
Maximum recovery achieved by 12-18 months. Return to low-impact activities. Avoid heavy lifting (>10 kg overhead), contact sports, and high-impact shoulder activities. Annual follow-up with X-rays.
