What is Shoulder Replacement Surgery and How Does it Work?
Shoulder replacement surgery, also known as shoulder arthroplasty, is a procedure to remove the damaged parts of the shoulder joint and replace them with artificial components, called a prosthesis. The primary goal is to relieve the pain caused by bone-on-bone friction and restore smooth, pain-free movement. This is a highly effective treatment for severe shoulder arthritis and other degenerative conditions.
Dr. Parentis performs two main types of shoulder replacement surgery:
- Anatomic Total Shoulder Replacement: This procedure is used when you have arthritis, but your rotator cuff tendons are still intact and functional. It mimics your natural anatomy. The damaged "ball" (humeral head) is replaced with a smooth metal ball, and the "socket" (glenoid) is resurfaced with a durable plastic cup. This restores the joint's original mechanics.
- Reverse Total Shoulder Replacement: This innovative procedure, which is rapidly growing and replacing anatomic replacements, is designed for patients who have severe arthritis as well as those with a torn, irreparable rotator cuff. In a reverse replacement, the anatomy is "reversed." The metal ball is attached to the socket, and the plastic cup is placed on the end of the arm bone. This design allows you to use your powerful deltoid muscle, instead of the torn rotator cuff, to lift your arm.
Dr. Parentis has special expertise in reverse total shoulder replacements and utilizes the latest robotic-assisted technology to perform this procedure. Through this advanced technology, he is able to achieve even more precise placement of the implants, leading to better outcomes for his patients.

Frequently Asked Questions About Shoulder Replacement Surgery
What Does Shoulder Replacement Surgery Treat or Help With?
Shoulder replacement surgery is primarily a solution for end-stage arthritis that has not responded to other treatments. One of the main shoulder joint pain causes is the loss of cartilage, which acts as a cushion in the joint. Without it, the bones grind against each other, causing severe pain and stiffness.
This surgery effectively treats:
- Osteoarthritis: "Wear-and-tear" arthritis that breaks down joint cartilage over time.
- Rotator Cuff Tear Arthropathy: A specific type of arthritis that develops after a massive, chronic rotator cuff tear. This is the main reason for a reverse shoulder replacement.
- Rheumatoid Arthritis: An autoimmune disease that causes severe inflammation and damage to the joint lining.
- Post-Traumatic Arthritis: Arthritis that develops after a significant shoulder injury, such as a fracture.
- Avascular Necrosis: A condition where the blood supply to the "ball" of the shoulder is lost, causing the bone to collapse.
The ultimate goal is to eliminate pain, restore motion, and allow you to return to your daily activities with confidence.
What Happens During a Shoulder Replacement Appointment?
Your first visit to Buffalo Orthopedics will likely be a comprehensive, one-on-one consultation with Dr. Parentis himself. He believes that the best outcomes start with a strong doctor-patient relationship built on trust and clear communication. He will listen carefully to your story, asking about the nature of your pain and how it limits your function.
Next, he will perform a detailed physical examination to assess your range of motion, strength, and the status of your rotator cuff. X-rays will be taken to evaluate the extent of the arthritis. In some cases, a CT scan or MRI may be needed to get a more detailed view of the bone and soft tissues. Based on this thorough evaluation, Dr. Parentis will explain your diagnosis in plain terms. He will discuss whether you are a candidate for an anatomic or a reverse shoulder replacement, making sure you understand all your options before creating a personalized treatment plan.
Is Shoulder Replacement Surgery Safe?
Shoulder replacement is a very safe and reliable operation when performed by an experienced, fellowship-trained surgeon. Dr. Parentis’s extensive training and 25 years of experience give him the expertise to perform these complex procedures with precision, which significantly minimizes risks and leads to excellent outcomes.
As with any major surgery, there are potential risks, including infection, blood clots, nerve injury, stiffness, or loosening of the implant over time. Dr. Parentis will have a frank and open discussion with you about these risks during your consultation. He is committed to patient safety and follows meticulous protocols in the operating room and during post-operative care to ensure the safest possible experience.
How is Shoulder Replacement Different from Other Treatment Options?
Before considering surgery, most patients try a range of conservative treatments. This includes anti-inflammatory medications, cortisone injections, and physical therapy. While these options can provide temporary relief from shoulder pain, they do not change the underlying arthritis. They manage symptoms but do not fix the mechanical problem of a worn-out joint.
Shoulder replacement surgery is different because it is a reconstructive solution. It physically removes the source of the pain—the damaged bone and cartilage—and replaces it with a new, smooth joint surface. For patients with severe, debilitating arthritis, it is the only treatment that offers the potential for complete pain relief and a lasting return to function.
How Long Does Recovery Take After Shoulder Replacement Surgery?
Recovery is a gradual process that requires your active participation. You will most likely go home the same day as the procedure. Your arm will be in a sling for about 1-2 days only.
Physical therapy is a critical part of your recovery and begins soon after surgery. The first phase focuses on gentle, passive motion to regain flexibility without stressing the joint. After the initial healing period, you will progress to active motion and then, several months later, to strengthening exercises. Most patients can return to light daily activities within a few weeks, but it can take 4-6 months to achieve the full benefit of the surgery. Dr. Parentis will guide you through every step of the rehabilitation process, ensuring a safe and steady return to the activities you enjoy.
