Anatomic Shoulder Replacement

Shoulder osteoarthritis (OA) is not as common as knee or hip OA, but it is estimated that almost 1 in 3 people over the age of 60 have shoulder OA. Most shoulder arthritis occurs after years of wear and tear on the joint, especially among physically active individuals. As the joint surfaces become worn, friction increases, triggering inflammation that leads to pain, stiffness, and limited mobility. Arthritis can also develop following an injury like a rotator cuff tear, a shoulder dislocation, or a fracture.

There’s no cure for arthritis, and that means most people with moderate to severe arthritis will need to consider having the joint parts replaced at some point using a state-of-the-art surgical procedure called shoulder arthroplasty.

  • Pain at the back of the shoulder that can feel like a deep ache
  • Pain with activity
  • Pain at rest
  • Pain at night
  • Stiffness and motion restriction
  • Arthritic crepitus – a sensation and sound that feels like grinding and clicking.

Anatomic shoulder arthroplasty uses special techniques to remove and replace the damaged portions of the shoulder joint including the ball-shaped head at the end of the upper arm bone (the humerus) and the cup-shaped glenoid socket on the shoulder blade.

Anatomic shoulder arthroplasty is a successful procedure to treat end-stage osteoarthritis, rheumatoid arthritis, and proximal humerus fractures; and for patient whose pain is not relieved or improved with all other treatments. Advancements in implant design, surgical technique and perioperative management reduce length of the hospital stay and postoperative complications.

Anatomic total shoulder arthroplasty is the gold standard procedure for patients with shoulder osteoarthritis who have an intact rotator cuff and sufficient socket bone to accommodate an implant. It has been shown to provide good to excellent results, reliable patient satisfaction, excellent implant longevity (10 years) and low rates of complications for these patients.

Patients with rotator cuff deficiency and osteoarthritis will have better outcomes with the nonanatomic option of reverse total shoulder arthroplasty.

You will wear a sling to protect and support the shoulder for up to six weeks. Icing applied to the shoulder will reduce discomfort. Rehabilitation begins on the first day after surgery and continues for three months post-surgery. Full recovery can take six months to a year.
