Yes, surgery is an option for shoulder arthritis, but it is not always the first step

Several surgical procedures can help shoulder arthritis, ranging from minimally invasive to major joint replacement. The right choice depends on how much cartilage damage you have, which part of the shoulder is affected, your age, activity level, and how much your symptoms interfere with daily life. Most people start with non-surgical treatments — physical therapy, anti-inflammatory medication, corticosteroid injections — and move to surgery only if those do not bring enough relief after several months.

The decision to have surgery is yours to make with your doctor. This guide explains what the main surgical options are, how they work, and what to expect afterward so you can have an informed conversation with your orthopedic surgeon.

Key Takeaways

  • Arthroscopic surgery cleans out loose cartilage and bone spurs and is less invasive than open surgery, but works best for mild to moderate arthritis.
  • Shoulder replacement (arthroplasty) removes the damaged joint surfaces and replaces them with artificial parts, and is typically recommended when arthritis is severe.
  • Reverse shoulder replacement is designed for people with rotator cuff tears alongside arthritis and changes how the shoulder mechanics work.
  • Recovery from arthroscopic surgery takes weeks to a few months; recovery from replacement surgery takes several months and requires committed physical therapy.
  • Not all shoulder arthritis requires surgery — many people manage symptoms well with exercise, activity changes, and injections over years.

Arthroscopic surgery: cleaning out the joint

Arthroscopy is a minimally invasive procedure where the surgeon makes two or three small cuts and inserts a camera and tiny instruments to look inside the shoulder joint. The surgeon can remove loose pieces of cartilage, smooth rough bone surfaces, and trim bone spurs that pinch tendons or nerves. Because the cuts are small, you go home the same day or the next day, and swelling and pain are usually less than with open surgery.

Arthroscopy works best for mild to moderate arthritis — when you still have some healthy cartilage left. It is less effective for severe arthritis where most of the cartilage is worn away. The procedure can reduce pain and improve movement for a year or two, but it does not stop arthritis from progressing. Some people need another arthroscopy later, or eventually move to replacement surgery.

Recovery is faster than with replacement: most people return to light activities within two to four weeks and resume normal activity within two to three months. Physical therapy starts within days and focuses on regaining strength and range of motion.

Shoulder replacement (arthroplasty): replacing the joint surfaces

Shoulder replacement removes the damaged ends of the upper arm bone (humerus) and shoulder blade (scapula) and replaces them with artificial parts made of metal and plastic. The surgeon makes one larger cut to access the joint, so this is more invasive than arthroscopy. Replacement is typically recommended when arthritis is severe — when X-rays show bone-on-bone contact or when arthroscopy has not provided lasting relief.

There are two main types. In anatomic shoulder replacement, the artificial ball and socket mimic the natural shoulder anatomy. In reverse shoulder replacement, the ball and socket are flipped — the artificial ball attaches to the shoulder blade and the socket attaches to the upper arm bone. Reverse replacement is used when arthritis occurs alongside a rotator cuff tear, because it changes how the shoulder muscles work and allows other muscles to do the job the rotator cuff can no longer do.

Shoulder replacement is major surgery. You stay in the hospital for one to two days. Recovery takes three to six months before you can return to most activities, and full recovery can take a year. Physical therapy is essential and intensive — you will work with a therapist multiple times per week for several months. Many people report significant pain relief and improved function, but you will have activity restrictions (no heavy lifting, no contact sports) for life.

Resurfacing: a middle option for younger people

Shoulder resurfacing is less common than replacement but may be offered to younger, active people with severe arthritis. Instead of removing the ball of the upper arm bone, the surgeon caps it with a smooth metal covering, like a crown on a tooth. The socket is resurfaced with a plastic lining. This preserves more of your natural bone, which can make revision surgery easier later if needed.

Resurfacing requires good bone quality and is not suitable if the upper arm bone is fractured or severely damaged. Recovery is similar to replacement — three to six months of intensive physical therapy. The long-term outcomes are still being studied, so your surgeon will discuss whether this is a reasonable option for your specific situation.

What happens before surgery: tests and preparation

Before any shoulder surgery, your surgeon will order imaging — usually X-rays and possibly an MRI or CT scan — to see exactly how much cartilage damage you have and whether your rotator cuff is intact. You will also have blood tests and possibly an EKG if you have heart concerns. Your surgeon will review your medications and may ask you to stop blood thinners or anti-inflammatory drugs a week or two before surgery.

You will meet with an anesthesiologist to discuss anesthesia options. Most shoulder surgery uses general anesthesia (you are asleep) combined with a nerve block (numbing medication around the nerves that supply the shoulder), which reduces pain after surgery. You will be told not to eat or drink after midnight the night before surgery.

Arrange for someone to drive you home and help you for the first few days. You will wear a sling to protect the shoulder and limit movement while healing begins.

Recovery and physical therapy after surgery

The first two weeks after surgery are focused on protection and gentle movement. You wear a sling most of the time, ice the shoulder to reduce swelling, and take pain medication as needed. Physical therapy usually starts within days — a therapist will show you gentle exercises to prevent stiffness and begin restoring motion.

After two to four weeks, you gradually increase activity. The sling comes off, and you begin strengthening exercises. This phase lasts several weeks. By two to three months after arthroscopy, most people are back to normal activity. After replacement surgery, this phase lasts longer — you are still in physical therapy and building strength at three months, and restrictions on heavy lifting remain for life.

Pain and swelling can linger for months after replacement surgery, even as function improves. Stiffness is common in the first few months but usually resolves with consistent therapy. If you skip physical therapy or do not follow activity restrictions, you risk poor outcomes — limited motion, persistent pain, or damage to the repair.

Risks and complications of shoulder surgery

All surgery carries risks. Infection, bleeding, and anesthesia reactions are rare but possible. Nerve or blood vessel injury can occur during surgery, though this is uncommon. After surgery, blood clots in the leg are a small risk, especially if you are immobile for long periods.

Specific to shoulder surgery: stiffness (frozen shoulder) can develop if you do not do physical therapy or move the shoulder enough during recovery. Implant loosening or wear can happen years after replacement, requiring revision surgery. Rotator cuff tears can occur after replacement, especially if you overuse the shoulder or fall. Persistent pain or limited motion despite surgery happens in a small percentage of cases and may require further treatment.

Your surgeon will discuss the specific risks for your situation and the steps taken to prevent them. Ask what warning signs to watch for after you go home — increased swelling, fever, severe pain, or numbness — and when to call the surgeon's office.

Frequently Asked Questions

How do I know if I need surgery or can manage with physical therapy?

Most people benefit from trying physical therapy, anti-inflammatory medication, and corticosteroid injections for at least three to six months before considering surgery. If pain is severe, you cannot sleep, or you cannot do basic daily tasks despite these treatments, surgery may be worth discussing. Your surgeon will look at imaging and your response to non-surgical treatment to advise whether surgery is likely to help.

Will shoulder replacement last the rest of my life?

Modern shoulder implants last 15 to 20 years on average, though some last longer. If you are younger when you have surgery, you may eventually need revision surgery to replace worn-out parts. Staying active within your restrictions and avoiding heavy lifting or contact sports helps implants last longer.

Can I go back to sports or heavy work after shoulder surgery?

After arthroscopy, many people return to sports and activities within a few months. After replacement surgery, you will have permanent restrictions — no heavy lifting (typically over 10 to 15 pounds), no contact sports, and no throwing sports. You can usually do swimming, walking, golf, and other low-impact activities once healed. Ask your surgeon what specific activities are safe for you.

What if surgery does not relieve my pain?

Pain relief after surgery varies. Some people have dramatic improvement; others have partial relief. If pain persists after surgery, your surgeon may recommend additional physical therapy, injections, or medications. Rarely, further surgery is needed. Discuss realistic expectations with your surgeon before surgery — imaging and your symptoms help predict how much relief you might get.

How much does shoulder surgery cost?

Cost varies widely depending on the type of surgery, your location, whether you have insurance, and your hospital. Arthroscopy is less expensive than replacement. If you have insurance, your out-of-pocket cost depends on your deductible and coverage. Contact your surgeon's office and insurance company for estimates before scheduling.
