Shoulder Arthroplasty

expert shoulder replacement in the villages, fl

Restoring movement, reducing pain, and getting you back to the life you love — with personalized orthopedic care from Dr. Alfred Cook and the AOI team.

About the Procedure

What Is Shoulder Arthroplasty?

The shoulder is a ball and socket joint — the rounded head of the upper arm bone (humerus) fits into a cup-shaped socket in the shoulder blade (scapula). In a healthy shoulder, smooth cartilage covers both surfaces, allowing fluid, pain-free movement.

When that cartilage breaks down — from arthritis, injury, or disease — bone can rub against bone, causing severe pain, stiffness, and limited mobility that significantly impacts daily life. When non-surgical treatments no longer provide relief,  shoulder arthroplasty may be the most effective path forward.

During the procedure, the damaged portions of the ball and socket are removed and replaced with prosthetic implants made of metal and high-grade plastic. These implants are designed to recreate the normal mechanics of your shoulder, restoring a smooth, functioning joint.

At Advanced Orthopedics Institute, serving patients throughout The Villages, Lady Lake, Leesburg and surrounding Lake and Sumter County communities, we are able to evaluate each patient individually to determine whether shoulder replacement is the right solution — and if so, which type of procedure will deliver the best outcome for your specific condition.

Indications for surgery

Conditions That May Require Shoulder Replacement

Osteoarthritis

Gradual wearing away of protective cartilage leads to bone-on-bone contact, pain, stiffness, and bone spur formation. The most common reason for shoulder replacements.

Rheumatoid Arthritis

An autoimmune condition where the body attacks joint tissue. In advanced stages, arthroplasty may be the best option to restore function and eliminate chronic pain.

Rotator Cuff Tear Arthropathy

Long-standing large rotator cuff tears alter shoulder mechanics and cause arthritis, often requiring a reverse total shoulder arthroplasty.

Severe Fractures

Complex fractures unlikely to heal correctly may be best addressed with joint replacement rather than repair, particularly in older patients.

Osteonecrosis

When blood supply to the humeral head is disrupted, bone tissue dies and the joint surface can collapse. Replacement is often the most effective solution.

Conditions That May Require Shoulder Replacement

Shoulder replacement is considered when joint damage is severe and conservative treatments no longer provide meaningful relief. Common causes include:

Total Shoulder Arthroplasty (Anatomic)

The damaged humeral head is replaced with a metal ball and the glenoid socket is resurfaced with a plastic component. Best when the rotator cuff tendons are intact.

Reverse Total Shoulder Arthroplasty

Ball and socket positions are switched, allowing the deltoid muscle to power movement. Preferred when the rotator cuff is severely torn or non-functional.

Hemiarthroplasty

Only the humeral head is replaced while the natural glenoid socket remains intact. Appropriate for specific fractures where the socket is still healthy.

What to Expect: Before, During & After Shoulder Replacement

  • Your Consultation at AOI Your journey begins with a comprehensive evaluation at our office in The Villages. Our team will review your medical history, discuss your symptoms, and order any necessary imaging — such as X-rays or MRI — to assess the condition of your shoulder joint. Together, you’ll discuss all available treatment options, conservative approaches first, and determine whether shoulder replacement surgery is the right next step.

  • Shoulder arthroplasty is typically performed under general anesthesia and takes approximately two to three hours. Dr Cook will make an incision at the front of the shoulder, carefully moving muscles aside to access the joint. The damaged bone surfaces are removed and the prosthetic components are precisely fitted. Most patients go home the same day or after a brief overnight stay.

  • Recovery & Rehabilitation Recovery from shoulder replacement is a gradual process. You’ll wear a sling for the first several weeks to protect the joint while it heals. Physical therapy — which we offer on-site at our Villages location — typically begins within the first few days and plays a critical role in restoring strength, range of motion, and function. Most patients begin to notice significant improvement within three to six months, with continued gains possible up to a year or more after surgery.

Frequently Asked Questions

Good candidates for shoulder replacement are typically patients who experience severe shoulder pain that limits daily activities, have tried conservative treatments — such as physical therapy, medications, or injections — without adequate relief, and whose imaging shows significant joint damage. Age, overall health, bone quality, and the condition of the rotator cuff all play a role in determining the most appropriate type of replacement. The best way to find out is through a personal consultation with one of our AOI practitioners.

In a standard (anatomic) total shoulder replacement, the prosthetic components mimic the natural anatomy of the shoulder — a metal ball replaces the humeral head and a plastic cup resurfaces the socket. A reverse shoulder replacement switches those positions, placing the ball on the socket side and the cup on the arm side. Reverse replacement is typically recommended when the rotator cuff is severely torn or no longer functional, as it allows the deltoid muscle to do the work of moving the arm.

Modern shoulder replacement implants are designed to be durable and long-lasting. Studies suggest that the majority of shoulder replacements remain functional for 10 to 20 years or more. Factors such as activity level, implant type, bone quality, and adherence to post-operative guidelines all influence longevity. Your AOI surgeon will discuss realistic expectations for your specific situation during your consultation.

Most patients wear a sling for four to six weeks after surgery. Physical therapy typically starts within the first week and continues for several months. Pain and swelling gradually improve over the first few weeks. Many patients can perform light daily activities within a few months, with more demanding tasks possible at six months or beyond. Full recovery — including maximum strength and range of motion — can take up to a year.

Yes. Physical therapy is a critical part of the recovery process and significantly impacts your outcome. At Advanced Orthopedics Institute, we offer on-site physical therapy in The Villages, making it convenient to access rehabilitative care as part of your overall treatment plan.

Many patients undergoing shoulder replacement return home the same day or after a single overnight stay, depending on their health, the complexity of the procedure, and the type of anesthesia used. Your care team will advise you based on your specific situation.

The REGENETEN® Bioinductive Implant is a minimally invasive, arthroscopic treatment for rotator cuff tears. It uses a small collagen-based scaffold to stimulate the body’s natural healing response and promote new tendon tissue growth. It is designed for patients with partial or full-thickness rotator cuff tears who want a less invasive alternative to traditional open rotator cuff repair. Ask your AOI physician whether you may be a candidate.

During your first visit, your AOI physician will review your health history, perform a physical examination of the shoulder, and discuss your symptoms and how they affect your daily life. Imaging studies such as X-rays may be taken on-site in our in-office radiology suite. You’ll leave with a clear understanding of your diagnosis and a recommended treatment plan tailored to your needs.
