Reverse vs. Anatomic Shoulder Replacement: Lancaster Shoulder Surgeon Explains Which Option Is Right for Patients

Michael J. Bercik Jr., MD, outlines how the two procedures differ and why the condition of the rotator cuff often decides the choice

LANCASTER, PA, UNITED STATES, October 29, 2026 /EINPresswire.com/ — Shoulder pain that limits sleep, work, and daily activities is one of the most common reasons people seek orthopedic care. At Lancaster Shoulder, Michael J. Bercik Jr., MD, and the shoulder team want patients to know that joint replacement is not one-size-fits-all. Michael J. Bercik Jr., MD, a Lancaster shoulder surgeon, recently explained the differences between the two main types of shoulder replacement, anatomic and reverse, and how surgeons decide between them.

Anatomic shoulder replacement

In an anatomic, or traditional, total shoulder replacement, the surgeon replaces the damaged surfaces with implants that mimic the natural anatomy. A metal ball is placed on the upper arm bone, and a smooth plastic socket is fitted to the shoulder blade.

“Anatomic replacement is designed to recreate the shoulder the way you were born with it,” said Dr. Bercik. “It works very well for patients whose arthritis has worn away the cartilage but whose rotator cuff is still healthy and functioning. The cuff tendons continue to do the job of powering and controlling the joint.”

Because the design depends on the rotator cuff, it is generally best suited to patients with osteoarthritis and an intact cuff.

Reverse shoulder replacement

A reverse shoulder replacement, as the name suggests, switches the positions of the ball and socket. The metal ball is fixed to the shoulder blade, and a cup-shaped implant is placed on the upper arm bone. This change in mechanics allows the large deltoid muscle on the outside of the shoulder, rather than the damaged rotator cuff, to lift and move the arm.

“Reverse replacement was a breakthrough for patients who previously had few good options,” said Dr. Bercik. “If the rotator cuff is torn beyond repair or no longer working, an anatomic implant may not perform well. By using the deltoid, a reverse replacement can restore comfort and function in those shoulders.”

Reverse replacement is commonly recommended for patients with large, irreparable rotator cuff tears, cuff tear arthropathy (arthritis that develops after long-standing cuff damage), certain complex fractures, and failed previous shoulder replacements. Surgeons also consider it for some older patients with advanced arthritis and weak or deficient cuff tissue.

Choosing the right procedure

Dr. Bercik emphasized that the decision is individualized and based on a thorough evaluation. Surgeons typically consider:
• Rotator cuff condition, assessed through a physical exam and imaging such as X-ray and MRI
• Bone quality and shape of the socket
• The patient’s age, activity level, and goals
• Prior shoulder surgeries or injuries

“My goal is never to push one procedure over another,” said Dr. Bercik. “It is to match the implant to the patient. When the right design is chosen for the right shoulder, patients can expect meaningful pain relief and a return to the activities they enjoy.”

Recovery and what to expect

Both procedures are typically performed with modern surgical techniques and a multimodal pain-management plan, and many patients go home the same day or after a short stay. Patients generally wear a sling for several weeks and then progress through guided physical therapy to rebuild motion and strength. Recovery timelines vary by procedure and individual, but most people continue to improve over several months.

When to seek care

Dr. Bercik encourages anyone with persistent shoulder pain, night pain, or loss of motion to be evaluated before the problem worsens. Many patients benefit first from non-surgical treatments such as activity changes, anti-inflammatory medication, physical therapy, or injections. Surgery is considered when those measures no longer provide relief.

“Early evaluation gives patients more options,” said Dr. Bercik. “Even if surgery turns out to be the answer, understanding the choices ahead of time makes people more confident in their care.”
