Shoulder Replacement Surgeon in Lancaster, PA

What Is Shoulder Replacement Surgery?

Shoulder replacement surgery removes damaged portions of the shoulder joint and replaces them with artificial components. The goal is to eliminate the bone-on-bone friction that causes pain, restore smooth joint movement, and help patients get back to activities that arthritis or joint damage has taken away.

The shoulder is a ball-and-socket joint. The ball is the rounded top of the upper arm bone, and the socket is the shallow cup on the shoulder blade. When cartilage breaks down and the joint surfaces begin to wear against each other, pain, stiffness, and lost function follow. Replacement surgery addresses that problem directly by resurfacing or replacing the damaged structures.

Shoulder replacement is not a first-line treatment. It is recommended when damage is advanced and conservative care has run its course.

Who Is a Candidate for Shoulder Replacement?

Shoulder replacement is most commonly recommended for patients with:

Severe shoulder arthritis. Osteoarthritis is the most common reason patients see a shoulder replacement surgeon. When cartilage wears down completely and pain becomes constant, replacement is often the most effective long-term solution.

Rheumatoid arthritis. Inflammatory arthritis can cause significant joint destruction over time. Shoulder replacement may be appropriate when the damage has become extensive.

Post-traumatic arthritis. Arthritis that develops after a shoulder fracture or major injury can progress to the point where conservative care is no longer effective.

Avascular necrosis. When blood supply to the humeral head is disrupted, the bone can deteriorate and collapse, often requiring joint replacement.

Failed previous shoulder surgery. Patients who have had prior shoulder procedures and continue to experience significant pain and dysfunction may be candidates for revision replacement.

Most candidates have already worked through physical therapy, anti-inflammatory medications, and cortisone injections without enough lasting relief. Shoulder replacement is typically the conversation that happens when those options have been exhausted.

Types of Shoulder Replacement Surgery

Not every patient needs the same procedure. Dr. Bercik evaluates each case individually and recommends the approach that fits the specific pattern of damage and the patient’s functional needs.

Total Shoulder Replacement

Total shoulder replacement replaces both the ball and the socket with artificial components. The humeral head is replaced with a metal ball attached to a stem that fits into the upper arm bone. The socket is resurfaced with a smooth plastic component. This is the standard approach for patients with shoulder arthritis and an intact rotator cuff.

Reverse Shoulder Replacement

Reverse shoulder replacement changes the mechanics of the joint by switching the positions of the ball and socket. The metal ball is attached to the shoulder blade side, and the socket component goes on the upper arm bone side. This design allows the deltoid muscle to power arm movement in place of a damaged or nonfunctional rotator cuff.

Reverse replacement is typically recommended for patients who have both severe arthritis and significant rotator cuff damage, a combination that makes standard total replacement less effective. It is also used in certain fracture cases and revisions.

Partial Shoulder Replacement

Partial replacement, also called hemiarthroplasty, replaces only the ball portion of the joint without resurfacing the socket. This approach may be appropriate in certain fracture cases or when socket cartilage remains largely intact.

Stemless and Resurfacing Options

In some cases, bone-conserving alternatives such as resurfacing or stemless implants may be considered depending on bone quality, age, and the nature of the joint damage.

Diagnosis and Surgical Planning

Before recommending shoulder replacement, Dr. Bercik conducts a thorough evaluation that includes a review of symptoms, medical history, prior treatment, and activity level. A physical exam assesses shoulder strength, range of motion, and areas of pain.

Imaging typically includes X-rays to evaluate joint space loss, bone quality, and alignment. CT scans help with implant sizing and positioning. MRI may also be used to assess the condition of the rotator cuff and surrounding soft tissue.

Understanding the full picture before surgery allows for a more precise plan and implant selection better matched to the patient. As a fellowship-trained shoulder replacement surgeon, Dr. Bercik brings a level of case-specific planning that directly affects both the function of the replacement and the longevity of the result.

The Surgical Procedure

Shoulder replacement is performed under anesthesia, typically a combination of general anesthesia and a regional nerve block to manage post-operative pain. The procedure involves carefully accessing the joint, removing damaged bone and cartilage, and implanting the prosthetic components.

Precise implant placement affects both the function of the replacement and long-term durability. Surgeon experience and specialization matter significantly in shoulder replacement outcomes, which is why patients seeking a shoulder replacement surgeon in Lancaster benefit from working with a surgeon whose practice focuses exclusively on shoulder conditions.

Most patients go home the same day or after one night in the hospital.

Recovery After Shoulder Replacement Surgery

Recovery from shoulder replacement is gradual and requires commitment to rehabilitation. The timeline varies depending on the procedure and the patient’s overall health, but here is a general overview of recovery.

First few weeks. The arm is kept in a sling to protect the joint during early healing. Gentle range of motion exercises typically begin within the first few days under the guidance of a physical therapist.

Weeks four through twelve. Physical therapy advances to include more active range of motion work and the beginning of light strengthening. Most patients are out of the sling by this point.

Three to six months. Strength and function continue to improve. Many patients return to most daily activities during this window.

Six months and beyond. Full recovery, including return to more demanding activities, typically occurs in the six to twelve month range depending on the procedure and the individual.

Patients who follow their physical therapy program closely typically recover more successfully. Following the rehabilitation program as directed is one of the most important factors in the long-term outcome.

His practice is limited exclusively to shoulder conditions. Treatment planning is individualized. The right implant, the right procedure, and the right rehabilitation program are chosen based on each patient’s specific situation, not a standard protocol.

Beyond replacement surgery, Dr. Bercik also treats rotator cuff tears, shoulder instability, labral tears, frozen shoulder, fractures, and acromioclavicular joint injuries from his three Lancaster County offices.

Shoulder Replacement Surgeon FAQs

Who is a shoulder replacement surgeon in Lancaster, PA? Dr. Michael Bercik is a board-certified orthopedic surgeon with sub-specialty training in shoulder surgery who performs shoulder replacement procedures at offices in Lancaster, Ephrata, and Mount Joy, PA. His practice is focused exclusively on shoulder conditions.

How do I know if I need shoulder replacement? Shoulder replacement is typically considered when arthritis or joint damage is advanced, pain is persistent despite conservative treatment, and daily function is significantly affected. A thorough evaluation with imaging helps determine whether replacement is appropriate.

What is the difference between total and reverse shoulder replacement? Total replacement is used when the rotator cuff is intact and replaces both the ball and socket in their natural positions. Reverse replacement switches the position of the ball and socket and is used when the rotator cuff is significantly damaged or nonfunctional.

How long does a shoulder replacement last? Modern implants are designed for long-term durability. Many shoulder replacements remain functional for fifteen to twenty years or more, though longevity depends on activity level, implant type, and individual factors.

Is shoulder replacement an outpatient procedure? Many patients go home the same day or after one night in the hospital. Your care team will determine the appropriate plan based on your health and the specifics of your procedure.

What is recovery like after shoulder replacement? Most patients are in a sling for the first several weeks and begin physical therapy early in the recovery process. Return to daily activities typically occurs over three to six months, with full recovery taking up to a year depending on the procedure.

Can both shoulders be replaced? If both shoulders are significantly affected, replacement may eventually be performed on each side, though typically not at the same time.What happens if a shoulder replacement wears out? Revision surgery is available for failed or worn-out implants. Dr. Bercik treats patients needing revision shoulder replacement as part of his shoulder-focused practice.
