The 6 most common shoulder surgeries

Six procedures account for the overwhelming majority of shoulder operations in the US: rotator cuff repair, total shoulder arthroplasty (TSA), reverse TSA, labrum repair, arthroscopic debridement, and AC joint reconstruction.

Each procedure repairs a different structure, and that difference drives everything downstream: anesthesia choice, incision size, sling duration, sleep restrictions, and the recovery timeline. This page describes all 6, then compares them side by side so you can place your own surgery in context.

The structures involved are covered in detail on the shoulder anatomy page — bones, joints, and the 4 rotator cuff muscles.

Surgery #1: rotator cuff repair

Rotator cuff repair reattaches a torn tendon — most often the supraspinatus — back to the humeral head using suture anchors.

Surgeons perform roughly 460,000 rotator cuff repairs per year in the US, making it the most common shoulder surgery. Around 90% are done arthroscopically through 3-4 incisions of 5-10 mm each; open repair through a single 4-6 cm incision is reserved for massive or retracted tears.

Rotator cuff repair has the longest recovery of the 6 procedures: 6 weeks in a sling, 4-6 months to full daily activity, and 6-12 months to final strength. Tendon-to-bone healing is the slowest tissue interface in the shoulder, and that biology — not surgical technique — sets the pace. The rotator cuff anatomy page explains the SITS muscles and tear patterns; the week-by-week rotator cuff sleep protocol maps every recovery phase.

Surgery #2: total shoulder arthroplasty (TSA)

TSA replaces both arthritic joint surfaces: a metal ball replaces the humeral head and a polyethylene socket resurfaces the glenoid.

Surgeons choose anatomic TSA for end-stage arthritis when the rotator cuff still works — the implant copies the natural joint geometry, so the cuff keeps doing its stabilizing job. The operation takes 1-2 hours through a 10-15 cm front incision under combined general anesthesia and nerve block.

TSA patients report the fastest pain relief of any major shoulder surgery, because the operation removes the arthritic surfaces that caused the pre-operative pain. Typical milestones: 4-6 weeks in a sling, daily activities by month 3, final strength between months 6 and 12. The TSA 12-week sleep plan covers position transitions for this procedure.

Surgery #3: reverse total shoulder arthroplasty

Reverse TSA swaps the geometry: the ball goes on the shoulder blade side and the socket goes on the humerus, which lets the deltoid muscle raise the arm without a working rotator cuff.

Surgeons choose the reverse configuration in 3 situations: massive irreparable rotator cuff tears, cuff tear arthropathy (arthritis caused by a chronic cuff tear), and failed previous repairs. Reverse TSA now outnumbers anatomic TSA in patients over 70.

Recovery is similar to anatomic TSA — 3-4 weeks in a sling, daily function by month 3 — but with one permanent trade-off: internal rotation (reaching behind your back) stays limited, and lifting limits of roughly 10-15 kg apply for life.

Surgery #4: labrum repair (SLAP and Bankart)

Labrum repair reattaches the torn fibrocartilage rim of the shoulder socket using 2-4 suture anchors, almost always arthroscopically.

The 2 dominant tear patterns split by cause: Bankart tears (front-lower labrum) follow dislocations and dominate in patients under 30; SLAP tears (top of the labrum) come from overhead sports and falls onto an outstretched arm. The labrum anatomy page diagrams both patterns.

Recovery runs 4 weeks in a sling and 4-6 months to full activity, with one procedure-specific restriction: external rotation stays limited for the first 4-6 weeks after Bankart repair to protect the front capsule. The labrum repair sleep guide translates that restriction into night positioning.

Surgery #5: arthroscopy (minor procedures)

Arthroscopic debridement and decompression are the “clean-up” operations: the surgeon removes inflamed bursa, frayed tissue, or bone spurs through 2-3 incisions of 5 mm, without repairing any structure.

Because nothing is sutured, nothing needs protected healing time. The sling comes off in 1-2 weeks, physical therapy starts within days, and most patients return to full activity in 6-12 weeks — the fastest recovery of the 6 procedures.

Surgery #6: AC joint reconstruction

AC joint reconstruction rebuilds the ligaments connecting the collarbone to the shoulder blade after high-grade separations — typically from cycling crashes, contact sports, and falls directly onto the shoulder point.

Grade 1-2 separations heal without surgery in 2-6 weeks. Surgery enters the picture at grade 3 and above, when the clavicle visibly rides up. Reconstruction uses a tendon graft or synthetic ligament, takes about 1 hour, and requires 4-6 weeks of sling protection with a recovery arc of 4-6 months.

Comparison table: all 6 procedures

Procedure	Incisions	Sling	Full recovery	Distinct feature
Rotator cuff repair	3-4 × 5-10 mm	6 weeks	6-12 months	Slowest tendon healing
Anatomic TSA	1 × 10-15 cm	4-6 weeks	6-12 months	Fastest pain relief
Reverse TSA	1 × 10-15 cm	3-4 weeks	6 months	Works without rotator cuff
Labrum repair	2-3 × 5 mm	4 weeks	4-6 months	Direction-specific limits
Arthroscopy	2-3 × 5 mm	1-2 weeks	6-12 weeks	Fastest overall
AC reconstruction	1 × 5-8 cm	4-6 weeks	4-6 months	Ligament graft

Risk profile by surgery type

Overall complication rates for shoulder surgery run 1-4%, and each procedure carries one signature risk:

Rotator cuff repair: re-tear. Rates range from 10% for small tears to 30-40% for massive tears — the dominant failure mode.
TSA and reverse TSA: implant-related issues. Infection (1-2%), implant loosening over 10-15 years, and nerve stretch injuries (mostly temporary).
Labrum repair: recurrent instability. 5-10% re-dislocation after Bankart repair, higher in contact athletes under 20.
Arthroscopy: persistent symptoms. The structural risk is minimal; the main disappointment is incomplete pain relief.
AC reconstruction: loss of reduction. The clavicle migrates back upward in 10-20% of cases, though function usually stays acceptable.

The full complication breakdown — infection, nerve damage, stiffness, blood clots — is on the shoulder surgery risks page.

What shoulder surgery costs in the US

Shoulder surgery costs between $6,000 and $22,000 before insurance: arthroscopic procedures sit at the $6,000-12,000 end, rotator cuff repair runs $8,000-16,000, and shoulder replacement runs $14,000-22,000.

Three cost drivers create the spread: facility type (hospital vs ambulatory surgery center — ASCs run 30-50% cheaper), implant hardware (anchors and prostheses), and anesthesia time. With insurance, the patient’s real number is the out-of-pocket maximum, typically $3,000-9,000 on US plans.

How to interpret your surgeon’s recommendation

Ask these 5 questions at the consultation; the answers map your case onto everything above:

Ask which structure is damaged — tendon, labrum, cartilage, or ligament determines which of the 6 procedures applies.
Ask whether the repair is time-sensitive. Retracted rotator cuff tears and locked dislocations lose repairability within months; arthritis does not.
Ask what happens without surgery. The non-surgical alternatives page covers PT, injections, and when they work.
Ask for the surgeon’s annual volume for your specific procedure. Outcomes correlate with volume; 50+ per year is an established benchmark for replacements.
Ask about the expected timeline for your tear size and age, then compare it against the generic recovery timeline.

A second opinion changes the treatment plan in roughly 30% of elective orthopedic cases — get one if the recommendation is surgery and the diagnosis took less than one imaging study. The do-I-need-surgery decision page lists the diagnostic criteria surgeons actually use.
