Shoulder Replacement: Total, Reverse and Partial, Recovery, Risks and Cost

Shoulder replacement (shoulder arthroplasty) swaps the worn or damaged ball-and-socket joint for artificial parts: a metal ball on the top of the arm bone and, in most cases, a smooth plastic socket, chiefly to relieve pain that painkillers, injections and physiotherapy no longer control. It relieves arthritic and cuff-related pain and restores useful movement; it is not a return to a twenty-year-old shoulder¹.

For two years I blamed the mattress, then my age, then my golf swing, before a surgeon put an X-ray on the screen and showed me a joint that had ground itself smooth, with a rotator cuff long past repairing. What I could not find anywhere was the plain account of the decision in front of me: whether I needed a total, a reverse, or a partial replacement, why my cuff decided that and not my birthday, and how long an artificial shoulder actually holds. This is the version I wanted then, written from my own reverse replacement outward and checked line by line by a consultant shoulder surgeon.

What is a shoulder replacement?

A shoulder replacement caps the worn ball at the top of the arm bone (the humerus) with a metal head and, in most cases, resurfaces the socket with a smooth plastic (polyethylene) component, so the glenohumeral joint can move without the grinding pain of bone on bare bone. The usual reason to operate is pain, not stiffness alone, once non-surgical measures no longer control it².

It is worth being clear about the limits from the start. The operation is superb at settling pain and giving back a working arm, but overhead and rotational range improves rather than returns in full, and the joint should not be loaded like an undamaged one. The honest boundaries are set out in what shoulder replacement will not fix.

The three operations: total, reverse and partial

Three operations share the same goal but suit different shoulders, and the choice turns mostly on the state of the rotator cuff: an anatomic total replacement keeps the natural layout and needs a working cuff; a reverse replacement switches the ball and socket so the deltoid lifts the arm when the cuff is gone; and a hemiarthroplasty replaces only the ball. Reverse designs have progressively expanded their indications and are now used across cuff tear arthropathy, complex fractures and many revision cases³.

The anatomic total suits osteoarthritis with an intact cuff. The reverse exists precisely because an anatomic replacement fails early when the cuff cannot power or stabilise the arm, so a metal ball is fixed to the socket side and the powerful deltoid muscle does the lifting instead⁴. The hemiarthroplasty, replacing the ball alone, is kept for some fractures of the top of the humerus and shoulders where the natural socket is well preserved. The fork that matters most is laid out in an anatomic versus a reverse shoulder replacement.

Am I a candidate?

Good candidates have shoulder pain that limits sleep and daily life, changes on imaging that match the pain, general health fit for an anaesthetic, and realistic expectations about what the arm will do afterwards. The usual reasons to operate are glenohumeral osteoarthritis, rotator cuff tear arthropathy, rheumatoid arthritis, avascular necrosis (bone death of the humeral head), or a complex fracture, once non-surgical measures no longer help¹.

The point that floored me was that the cuff, not my age, drove the decision. An intact cuff points toward an anatomic total; a torn, irreparable cuff with arthritis points toward a reverse, which is why the case for that operation sits in rotator cuff arthropathy and reverse replacement. For the full picture of who the surgery genuinely suits, see am I a candidate for shoulder replacement.

The procedure

Most primary replacements take roughly 1.5 to 2 hours (about 1 to 3 hours overall, longer for complex or revision work), usually under a general anaesthetic combined with a regional nerve block that numbs the shoulder for pain relief afterwards. The surgeon reaches the joint through a cut at the front of the shoulder, between the deltoid and chest muscles¹.

It is commonly a 1 to 2 night hospital stay, though selected fitter patients now have it as a day case². Mine felt less like a single dramatic event than a careful piece of work I woke from with the arm already numb and strapped across my chest. What the day itself involves is covered in the shoulder replacement procedure, and the anaesthetic in shoulder replacement anaesthesia.

Recovery

The arm rests in a sling for about 2 to 6 weeks, commonly around 3 to 4, with reverse replacements often out of the sling sooner; physiotherapy starts early, with gentle passive and pendulum movements first, building to active movement and then strengthening over the following months. Most people return to driving at about 6 weeks and to desk-based work between roughly 2 and 6 weeks, while heavier or overhead work waits 3 to 6 months⁵.

Pain settles first; the shoulder keeps gaining strength and movement over 6 to 12 months, and the arm I actually wanted turned up somewhere around the six-month mark, not the six-week one. The rehab, not the operation alone, makes the result, which is why physiotherapy after shoulder replacement matters as much as the surgery. The honest stage-by-stage version is in shoulder replacement recovery week by week.

How long does it last?

Most shoulder replacements last well, with pooled registry and study data putting overall survival at around 90% still in place at 10 years; anatomic total replacements are commonly quoted at roughly 90% to 95% at 10 years, and primary reverse replacements at over 90%. Long-term series of reverse replacements followed for a minimum of ten years report favourable, if variable, survivorship⁶.

After the first decade the risk of needing a revision is roughly 1% per year, so a replacement put in at a younger age is more likely to need redoing in a lifetime¹. It does not stop the underlying disease elsewhere, and a worn plastic surface, loosening, or a failing cuff can eventually bring a shoulder back to surgery. The full account is in how long does a shoulder replacement last.

Risks and complications

Infection affects roughly 1 in 100 (about 1%, reported from 0 to 4%) of primary shoulder replacements, with reverse replacements carrying a somewhat higher rate; other named risks are nerve injury, dislocation, loosening or wear, and periprosthetic fracture. Nerve injury, most often a stretch of the axillary nerve, is usually temporary; dislocation is more common after a reverse replacement than an anatomic one⁴.

Loosening or wear of the components over time, a break around the implant, and, in anatomic replacements, later rotator cuff failure or glenoid loosening are all recognised reasons for revision, and reverse replacements have a higher overall complication rate, the trade-off for working without a functioning cuff¹. No joint replacement is risk-free, and the shoulder is major surgery under anaesthetic. The full account is in shoulder replacement risks and complications, with the infection question set out separately in shoulder replacement infection.

How much does it cost?

In the US the orthopaedic surgeon’s professional fee is commonly about $1,500 to $5,700, a small slice of the total, with the all-in cost usually estimated at roughly $15,000 to $30,000 (wider figures of about $14,000 to $52,000 are reported) once the hospital, implant and anaesthesia are added; the hospital or facility fee is the largest part. UK private surgery is commonly £10,000 to £15,000, with a reported range of about £7,000 to £21,000².

In the UK it is a standard NHS operation, funded when clinically indicated because it is not a cosmetic procedure, though waiting times can be long⁵. Prices advertised abroad are lower, often around $5,000 to $12,000, but these are marketing figures, not audited averages, and exclude flights, accommodation, an extended stay, and follow-up.
