What Are the Different Types of Shoulder Surgery?

Shoulder surgery spans a wide range of procedures, from minimally invasive arthroscopic repairs that take under an hour to full joint replacements that swap out the damaged ball-and-socket with metal and plastic implants. The right operation depends on what is wrong: a torn rotator cuff, a shoulder that keeps dislocating, cartilage damage from arthritis, or a labral tear that will not heal on its own. Each condition has its own surgical options, and the evidence behind those options has shifted considerably in recent years, with some once-popular procedures now falling out of favor.

Rotator Cuff Repair

Rotator cuff tears are one of the most common reasons people end up in a shoulder surgeon’s office. When conservative treatment like physical therapy and injections is not enough, surgery aims to reattach the torn tendon to the bone of the upper arm. The two main approaches are open surgery, which involves a larger incision and direct visualization, and arthroscopic surgery, which uses small incisions and a camera. A systematic review of long-term results found no significant differences in functional scores, complication rates, or retear rates between the two approaches.¹ A separate study found slightly lower complication rates with the arthroscopic method (about 2% versus 4%) and marginally better quality-of-life scores, though these differences were not statistically significant.²

Within arthroscopic repair, surgeons choose between single-row and double-row fixation, which refers to how the tendon is anchored back to the bone. Double-row techniques use more anchor points to spread the load across a larger footprint. A systematic review found that healing rates at two years were about 89% with double-row fixation compared to 79% with single-row, a statistically significant difference.³ This does not mean every patient needs double-row repair. For smaller tears, the difference matters less, and the added complexity and cost may not be justified.

Retears remain the main concern after rotator cuff surgery. Risk factors include the size of the original tear, the patient’s age, whether they have diabetes, and the type of work they do. Patients who perform manual labor have roughly double the retear risk compared to those with desk jobs.⁴ Rehabilitation choices, shoulder anatomy, and the repair technique itself all play a role as well.⁵

When the Rotator Cuff Cannot Be Repaired

Some rotator cuff tears are too large or too retracted to pull back together. For these irreparable tears, superior capsule reconstruction is one option. The idea is to bridge the gap between the remaining cuff tissue and the bone by grafting a patch of tissue across the top of the joint. A cadaveric study showed that this approach completely restored the upward stability of the joint.⁶ The graft material can come from a donor (dermal allograft) or from the patient’s own body (tensor fascia lata autograft from the outer thigh). Both options show similar graft failure rates of roughly a third, though autograft patients recover motion faster while allograft patients experience quicker pain relief.⁷ A failure rate around one-third is not ideal, and for many patients with massive irreparable tears, reverse shoulder replacement (discussed below) is the more reliable long-term solution.

Surgery for Shoulder Instability

When the shoulder dislocates repeatedly, surgery aims to restore the structures that keep the ball centered in the socket. The most common procedure is the Bankart repair, which reattaches the torn labrum (the ring of cartilage around the socket’s rim) using small anchors placed arthroscopically. A meta-analysis estimated an overall recurrence rate of about 17% after arthroscopic Bankart repair, with younger patients and those followed for longer periods showing higher rates of redislocation.⁸

Younger patients face a particularly tough outlook. A study tracking patients for an average of eight years found that about 31% experienced recurrent instability, with nearly half of those needing revision surgery. Patients who had already dislocated two or more times before surgery had significantly higher recurrence rates, and those who were younger at first dislocation fared worse on almost every measure, including return-to-sport rates.⁹ The takeaway from that research is straightforward: operating sooner, before repeated dislocations erode the bone and stretch the capsule, leads to better results.

When significant bone loss is present on the socket side, soft-tissue repair alone is not enough. The Latarjet procedure addresses this by transferring a small piece of bone (the coracoid process, along with its attached muscle) to the front of the socket, effectively rebuilding the missing bony wall.¹⁰ In patients with major bone loss where arthroscopic Bankart repair had a 67% failure rate, the Latarjet procedure brought the recurrence rate down to about 5% at roughly five years of follow-up.¹¹ It is a more involved operation with a longer recovery, but for the right patient it is dramatically more reliable.

Shoulder Replacement

When arthritis has worn away the cartilage surfaces of the shoulder, replacement surgery becomes the primary surgical option. There are two fundamentally different designs, and the choice between them depends on the condition of the rotator cuff.

Anatomic Total Shoulder Replacement

An anatomic total shoulder replacement mimics the natural joint: a metal ball replaces the humeral head and a plastic cup resurfaces the glenoid (the socket). This design works well when the rotator cuff is intact, because the cuff muscles are still needed to stabilize and move the joint. Long-term results are encouraging. One study of 78 shoulders followed for an average of 15 years found that implant survival was 97% at ten years and 72% at twenty years, with large improvements in range of motion and pain.¹² Another study reported 89% implant survival at the ten-year mark with good functional scores and low pain levels.¹³

The weak link in an anatomic replacement is the plastic socket component, which can loosen from the underlying bone over time. Glenoid loosening remains one of the most common causes of failure in total shoulder arthroplasty.¹⁴ A systematic review comparing different glenoid designs found that modern metal-backed glenoid components had lower loosening rates than traditional all-polyethylene cemented components over the long term, though the two performed similarly in the first few years.¹⁵

Reverse Total Shoulder Replacement

The reverse shoulder replacement flips the ball-and-socket arrangement: a metal ball is fixed to the socket side and a plastic cup is placed on the arm bone. This configuration changes the biomechanics so that the deltoid muscle, rather than the rotator cuff, drives arm elevation. By medializing the center of rotation, the design lengthens the deltoid’s lever arm and makes it more efficient.¹⁶ This makes reverse replacement the go-to option for patients who have severe arthritis combined with an irreparable rotator cuff tear, a scenario where an anatomic replacement would fail because there is no cuff to stabilize it.

Early reverse designs had problems with a complication called scapular notching, where the humeral component repeatedly contacts and erodes the bone below the socket. Newer generations have addressed this by modifying the position and angle of the glenosphere and humeral components, which biomechanical and clinical studies suggest reduces impingement and notching.¹⁷ The indications for reverse replacement have also expanded beyond cuff-tear arthropathy to include certain fractures, failed prior replacements, and tumors.

Subacromial Decompression and the Impingement Debate

For decades, shoulder “impingement syndrome” was treated by shaving away part of the acromion bone to create more space for the rotator cuff tendons underneath. This operation, known as subacromial decompression or acromioplasty, was one of the most commonly performed shoulder procedures in the world. The evidence now strongly argues against it. A Cochrane review concluded with high certainty that subacromial decompression provides no improvement in pain, function, or quality of life compared to a sham (placebo) surgery at up to one year.¹⁸

A Finnish trial (FIMPACT) extended this finding to a full decade of follow-up, finding no difference between real decompression and placebo surgery in pain at rest, pain during activity, or any secondary outcome.¹⁹ The broader understanding of impingement has evolved alongside these trials. What was once thought to be a simple mechanical problem of bone pinching tendon is now recognized as a more complex mix of intrinsic tendon changes, movement patterns, and other factors that bone shaving does not address.²⁰ If your surgeon recommends acromioplasty as a standalone procedure for shoulder pain without a structural tear, it is worth asking what the expected benefit is, because the highest-quality evidence says there is none beyond placebo.

Labral Tears and Biceps Tendon Surgery

The labrum can tear in locations other than the front of the shoulder. SLAP tears (superior labrum anterior-to-posterior) affect the top of the labrum where the biceps tendon attaches. Historically, these were repaired arthroscopically by reattaching the torn labrum with anchors. But outcomes were inconsistent, particularly in patients over 35 or those without a clear traumatic cause.

An alternative is biceps tenodesis, which detaches the biceps tendon from the labrum entirely and reanchors it lower down on the arm bone, effectively taking the problematic attachment out of the equation. A meta-analysis found that patients treated with tenodesis had significantly higher satisfaction rates (about 96% versus 76%) and were more likely to return to their preinjury sport (about 81% versus 64%) compared to those who had SLAP repair.²¹ A separate meta-analysis confirmed significantly better return-to-sport rates and satisfaction in the tenodesis group, with no significant differences in pain scores, functional outcomes, or reoperation rates between the two approaches.²² For most adults with SLAP tears, tenodesis has become the preferred operation, though SLAP repair may still be the better choice in young overhead athletes who need the biceps anchor intact.

Frozen Shoulder Surgery

Adhesive capsulitis, or frozen shoulder, usually resolves on its own over one to three years, but some patients reach a point where the stiffness and pain are intolerable. Two surgical options exist: manipulation under anesthesia, where the surgeon forcefully breaks up the scar tissue while the patient is asleep, and arthroscopic capsular release, where the thickened capsule is carefully cut with instruments. A meta-analysis found that capsular release produced slightly better forward flexion at three and six months, but by one year the two procedures were equivalent in pain, range of motion, and complications.²³ The choice often comes down to surgeon preference and the severity of the case, with capsular release offering more controlled tissue release and manipulation being faster and less invasive.

AC Joint Surgery

The acromioclavicular (AC) joint, where the collarbone meets the top of the shoulder blade, can separate from a fall or direct blow. Lower-grade separations heal with rest and a sling, but higher-grade injuries where the collarbone is displaced upward often need surgery. Surgical approaches broadly fall into three categories: direct fixation of the AC joint (such as hook plates), fixation between the coracoid bone and the clavicle (using screws or loop-and-button devices), and full ligament reconstruction.²⁴

Older techniques using pins or screws had high rates of hardware migration and breakage. Newer arthroscopic-assisted techniques using suture-button constructs have shown promising early results with lower complication rates.²⁵ One recent technique uses a single drill hole in the clavicle with a tensionable suture system, avoiding the need to drill through the coracoid entirely and reducing the risk of fracture at the drill sites.²⁶ The field is still working out which technique is best, and there is no consensus. The trend is clearly toward less hardware and more biologic augmentation.

Pain Management Around Shoulder Surgery

How pain is controlled during and after surgery affects recovery more than many patients realize. The traditional gold standard for shoulder surgery pain control is the interscalene nerve block, an injection near the neck that numbs the nerves supplying the shoulder. It provides excellent early pain relief but wears off after 12 to 24 hours, which can leave patients facing a “rebound pain” spike. An alternative is liposomal bupivacaine, a long-acting local anesthetic injected directly into the surgical site. Multiple meta-analyses have compared the two and found no significant differences in pain scores or opioid use at 24 and 48 hours.²⁷ One meta-analysis found that liposomal bupivacaine was associated with slightly lower pain scores at 12 and 24 hours and a modest reduction in hospital stay.²⁸ The nerve block does carry a small risk of temporary diaphragm weakness (because the phrenic nerve runs nearby), which can be a concern for patients with lung problems. For most patients, either option works well, and many surgeons now use a combination of approaches.

Infection Risk Unique to Shoulder Surgery

Shoulder surgery has an unusual infection profile compared to other joints. The bacterium Cutibacterium acnes lives deep in the skin’s sebaceous glands around the shoulder and is the most common cause of infection after shoulder replacement. It does not behave like a typical surgical infection: there may be no redness, fever, or swelling. Instead, patients often present with unexplained pain and stiffness months or even years after surgery.²⁹

Diagnosing C. acnes infection is tricky because standard blood tests for infection often come back normal, and cultures need to be held for 14 days or longer to detect it. Standard preoperative skin preparation with chlorhexidine does not reliably eliminate it from the deep skin layers. There has been a shift toward using topical benzoyl peroxide before surgery, which reaches deeper into the pores and shows better results at reducing bacterial loads.³⁰ Men are at higher risk because they have more sebaceous glands in the shoulder area. Treatment typically requires a long course of antibiotics (often around three months) and may involve a one-stage or two-stage implant exchange, though the prognosis is generally favorable when caught and treated appropriately.³¹

Rehabilitation Timing After Rotator Cuff Repair

A common question after rotator cuff surgery is how soon to start moving the shoulder. Surgeons historically split into two camps: early passive motion (starting within days of surgery) and delayed motion (immobilizing for four to six weeks first). The fear with early motion is that it could stress the repair before the tendon heals, while the concern with delayed motion is stiffness. The evidence suggests both protocols produce similar outcomes. A randomized trial found no significant differences in satisfaction, healing, or range of motion between early and delayed groups, though the delayed group had a slightly higher healing rate (91% versus 85%).³² A meta-analysis of randomized controlled trials confirmed no difference in retear rate, rotation, or functional scores between the two approaches.³³ The practical consequence is that most surgeons now feel comfortable tailoring the timeline to the individual repair, protecting larger or more tenuous repairs with longer immobilization while allowing earlier motion for smaller, well-fixed tears.

Returning to Sport After Shoulder Surgery

How quickly and successfully you get back to athletics depends heavily on the surgery you had and the demands of your sport. Overhead athletes face the longest road. Among professional baseball players who underwent rotator cuff repair, only about a third returned to play, and fewer than 15% came back at the same or higher level. For professional pitchers specifically, the numbers were even more sobering: just one in twelve returned to competitive baseball.³⁴ Recreational athletes and those in non-overhead sports fare much better. The demands of throwing a ball at extreme velocities are fundamentally different from the demands of swimming, lifting, or playing a contact sport, so return-to-play statistics are not one-size-fits-all.

Patient-Specific Guides and Surgical Technology

One of the challenges in shoulder replacement is placing the glenoid (socket) component accurately. Even a few degrees of tilt can change the joint’s mechanics and contribute to early loosening. Three-dimensional CT-based planning allows surgeons to map the patient’s anatomy before surgery and create custom guides that fit onto the bone and direct the drill path. In vitro testing showed that patient-specific guides achieved an average version angle error under 2 degrees and an entry-point error of about 1 millimeter.³⁵ Similar accuracy has been demonstrated for reverse shoulder replacement, with translational errors averaging about 1.2 millimeters and tilt errors just over a degree.³⁶ Whether this improved accuracy translates into better long-term outcomes is still being studied, but the precision is clearly better than freehand technique, and many high-volume shoulder surgeons have adopted this technology as standard practice for complex cases.
