Shoulder replacement is a major but highly effective operation. Good preparation makes a significant difference to your recovery. This guide takes you through everything step by step.
ℹ️ This appointment usually takes place 2–4 weeks before surgery. Because shoulder replacement is a major procedure, this assessment is thorough.
You will meet the nursing and anaesthetic team for a detailed review. Shoulder replacement requires careful preparation including cardiac and respiratory assessment.
A full pre-operative screen including full blood count, kidney function, and clotting.
Blood thinners, anti-inflammatory drugs, and immunosuppressants (if taken for rheumatoid arthritis) may need to be adjusted before surgery.
General anaesthesia with an interscalene nerve block is usual. The block provides excellent pain relief for the first 12–18 hours after surgery.
You will be asked to ensure there are no active dental infections, as bacteria from the mouth can seed a new joint replacement. See your dentist before surgery if needed.
You will need significant help at home. Arrange for someone to stay with you for at least the first week. Set up a sleeping area downstairs if possible, as stairs may be challenging initially.
ℹ️ You will be given a specific arrival time. Have no food from 2am on the day of surgery; you may drink clear water until 6am. Bring your medication list and any documents sent by the hospital.
You will be admitted to the ward or day surgery unit, change into a gown, and be seen by the nursing, anaesthetic, and surgical teams before theatre.
Your surgeon will confirm the procedure, mark the operative side, and you will sign a consent form before going to theatre.
You will meet the anaesthetist in the anaesthetic room. Once anaesthesia is established, the procedure will begin.
After surgery you will wake in the recovery room where nurses monitor your vital signs until you are stable and comfortable.
Most patients having arthroscopic or day-case procedures go home on the day of surgery. Those having joint replacement typically stay 1–2 nights. Before discharge, the team will check your pain is controlled, give you wound care instructions, and confirm your follow-up appointment.
You will be given oral pain relief before discharge. Take it regularly for the first 48 hours rather than waiting until pain is severe.
A nurse will check the wound before you leave and explain how to keep it clean and dry.
You will receive a letter for your GP and details of your next outpatient appointment - usually at 2 weeks for a wound check.
Arrange for a family member or friend to collect you. You must not drive on the day of surgery if you have had a general anaesthetic or sedation.
⚠️ Important: Report any signs of infection - redness, warmth, swelling, discharge from the wound, or fever - immediately to your surgical team. Infection of a joint replacement is a serious complication requiring prompt treatment.
Avoid getting the wound wet until it is fully healed - usually 10–14 days. Use a waterproof cover or cling film when showering.
Do not wait until pain is severe before taking medication. Regular simple analgesia (paracetamol, ibuprofen if appropriate) is more effective.
This is usually 2 weeks after surgery. Sutures or clips will be removed if used.
Seek urgent advice if you develop increasing redness, warmth, swelling, discharge from the wound, or a temperature above 38°C - these may indicate infection.
Full medical assessment, dental check, medication adjustment, and arranging home support.
The procedure takes 1.5–2.5 hours. Most patients stay 1–2 nights in hospital.
The arm is supported in a sling. Gentle pendulum exercises help prevent stiffness.
Strengthening exercises begin. Return to driving is usually possible around 8 weeks.
Full recovery, including return to overhead activities and sport, typically takes 9–12 months.
Most patients wear a sling for 4–6 weeks after shoulder replacement. Your surgeon will advise on the duration based on the type of replacement performed.
You should not drive with a sling in place. Most patients return to driving around 6–8 weeks after surgery, when the shoulder is strong enough to control the wheel safely.
Many patients find sleeping slightly reclined easier in the first week or two. A recliner chair or wedge pillow may be helpful.
Most shoulder replacements allow return to everyday activities and gentle sport. High-impact activities and heavy lifting above shoulder height should generally be avoided long-term.
A week-by-week guide to recovery. Individual timelines vary, always follow your surgical team.
The primary aim of shoulder replacement is reliable and durable pain relief. Improvement in range of movement and function is also expected, though the degree varies by the type of replacement and the underlying condition.
Under general anaesthetic, the shoulder is approached through a deltopectoral incision. The humeral head is removed and the humeral canal is prepared to receive a cemented or uncemented metal stem. For total anatomical replacement, the glenoid is resurfaced with a polyethylene component. For reverse replacement, the humeral and glenoid components are reversed (ball on glenoid, socket on humerus). For hemiarthroplasty, only the humeral side is replaced. The wound is closed in layers over a drain.
Physiotherapy, analgesics, activity modification, and injections. May provide acceptable symptom control without the risks of surgery.
Corticosteroid or hyaluronic acid injection. Short-term benefit only; does not alter the underlying arthritis.
For early arthritis, arthroscopic washout and debridement may give temporary improvement. Not appropriate for advanced joint destruction.
The choice between total, reverse, and hemi replacement will be discussed specific to your diagnosis and imaging findings.
Some visible change in the appearance of the shoulder (such as a hollow under the collarbone or wasting of the muscle around the shoulder blade) may be noticeable after surgery, particularly with a reverse shoulder replacement.
The nerves around the shoulder (particularly the axillary nerve) can be stretched or bruised during surgery. Most of these injuries are temporary and recover fully over weeks to months. Permanent nerve injury is rare.
The upper arm bone or the shoulder blade can occasionally crack during preparation of the bone or insertion of the implant. If this happens it is fixed at the same operation.
Bleeding can occur during or shortly after surgery. In some cases a blood transfusion may be needed. Measures are taken during surgery to minimise blood loss.
Damage to the major blood vessels near the shoulder (the axillary artery and vein) is rare but serious. If this happens, repair by a vascular surgeon may be needed.
All operations carry general risks, including reactions to medications, breathing problems, and (rarely) heart or stroke events during the perioperative period. These risks are higher in older patients and those with other medical conditions, and will be discussed by the anaesthetic team.
Some pain is expected after surgery. This is managed with regular pain relief, including a nerve block around the time of the operation.
Surgery does not always fully relieve pain or stiffness. A small number of people are left with symptoms similar to before the operation despite a technically successful procedure.
A superficial infection of the wound or stitches, usually settling with a course of antibiotics.
The new joint can come out of position, especially with reverse shoulder replacement. Most dislocations can be put back without further surgery, but sometimes revision surgery is needed.
Some shoulder stiffness can persist, particularly if the shoulder was stiff before surgery or if physiotherapy is not followed through. Range of movement after replacement is usually less than the normal side.
A deep infection around the implant is a serious complication. It usually requires further surgery, often to take the implant out, a long course of antibiotics, and replacement of the joint later as a second operation.
Clots can form in the veins of the leg (DVT) or travel to the lungs (pulmonary embolism). Preventive measures (early movement, compression, sometimes medication) are taken to reduce this risk.
All operations leave a scar. The scar from a shoulder replacement runs along the front of the shoulder and usually fades over the first year, although it remains permanently visible.
The implant can gradually loosen from the bone over many years. Loosening is the most common reason a shoulder replacement needs to be redone. Revision surgery is more complex than the first operation.
A fall or injury after surgery can fracture the bone around the implant (periprosthetic fracture). These breaks often need further surgery to fix.
A shoulder replacement is not necessarily permanent. If the implant wears out, dislocates repeatedly, becomes infected, or loosens, a second operation to replace the components may be needed. Results of revision surgery are generally less reliable than the first operation.
End-stage shoulder arthritis causing significant pain and functional limitation is unlikely to improve without surgery. Non-operative management may provide temporary relief but does not address the underlying joint destruction. Delaying surgery does not make the operation more difficult, but prolonged pain and reduced activity may affect overall health and the quality of the physiotherapy recovery.
Plain-English answers to the things people most often ask, drawn from real patient questions and grounded in published guidance. Tap a question to open it.
Recovery usually means a sling for several weeks then progressive rehabilitation, with steady gains over about six months and strength improving for a year or more. Most people get good pain relief and useful function, and many return to low-impact activities such as walking, swimming, golf and gardening once healed.
After a reverse replacement in particular, the shoulder will not usually regain completely normal strength or extreme overhead reach, and heavy lifting, contact sport and high-impact activity are generally discouraged to protect the implant.
Modern implants last a long time: many are still working well at 10 to 15 years and beyond, and for older patients the replacement often lasts the rest of their life. Younger and very active people should understand that an implant has a finite lifespan and may eventually need revision, which is part of why age and activity are weighed up before surgery.
A bit of preparation makes the first weeks much easier: get as fit and well as you reasonably can, set your home up so things are within reach of your good arm, sort loose front-opening tops and slip-on shoes, and arrange help for the first week or two if you live alone. If you have diabetes, flag it early, as it affects healing and the response to any steroid used around the operation.
Good questions to take to clinic include: exactly what is being done and why; how long in the sling and what type; when physiotherapy starts; what to expect at six weeks, three months and a year; the pain-relief plan and whether you will have a nerve block; when you can shower, drive, work and return to your sport; and the main risks, including the chance of re-tear.
A nerve block numbs the nerves to the shoulder and arm, usually alongside a general anaesthetic, and gives excellent pain relief for roughly the first 10 to 24 hours. The arm often feels heavy and numb during that time, which is expected.
As it wears off, usually the evening or night after surgery, pain can return quite suddenly ("rebound pain"). This is well recognised and not a sign anything is wrong. Start your prescribed pain relief on schedule before the block fully wears off, so you stay ahead of it. A hoarse voice, a drooping eyelid, or a feeling of breathlessness can occur as the block spreads to nearby nerves; these settle as it wears off, but tell your anaesthetist beforehand if you have significant lung disease, asthma or sleep apnoea.
Sleep is one of the hardest parts of early recovery. Many people sleep semi-upright in a recliner or well propped up, supporting the operated arm on pillows, and keep the sling on at night for as long as the surgeon advises. Expect broken sleep for several weeks and try not to measure recovery by it.
Sling time varies with the operation, commonly around the first six weeks for a repair. Neck and upper-back ache from the strap is very common; easing and padding the strap helps, as do gentle hand, wrist and elbow movements. Do not stop the sling early just to get comfortable; wait until your surgeon clears it.
Pain is usually managed with a combination: the nerve block, regular paracetamol, an anti-inflammatory if safe for you, a short course of a stronger painkiller for the first few days, and ice. Using several milder approaches together often works better, with fewer side effects, than one strong drug.
If opioids make you sick, or you cannot take anti-inflammatories (stomach, kidney, heart or stroke history), this is common, so tell your team in advance to plan around it. One point that causes confusion: ketorolac (Toradol) is an anti-inflammatory given by mouth, muscle or drip, not an injection into the shoulder joint. Your prescriber decides what is safe for you.
Showering depends on your dressings and your surgeon's advice, so follow the instruction you were given. Keyhole wounds are small, but the skin around them can feel dry, tight or crispy and catch on clothing; a loose dressing stops it rubbing, and once fully healed a plain moisturiser can settle the dryness.
The incision points can stay tender for several weeks, which is normal. Once healed, gentle scar massage (your physiotherapist can show you) reduces sensitivity over time, and it is worth protecting healing scars from strong sun. Do not put creams on a wound that is not yet closed, and report spreading redness, heat, discharge or fever.
There is no single fixed date, and it is ultimately your responsibility to be safe and legal. As a rough guide, UK services often suggest driving around six to eight weeks after a repair, when you can control the car and perform an emergency stop confidently without significant pain, and you are not taking medication that affects alertness. It is also sensible to check your motor insurance position first.
Desk work is often possible around six to eight weeks, and heavier manual work around four to six months, depending on the job and the operation. Your surgeon's specific advice always takes priority.
Yes, and it is talked about far too little. Frustration, low mood, isolation and poor sleep are common while you are in a sling and reliant on others, and it does not mean recovery is going badly. Keeping gently active within your limits, staying connected to people, and marking small milestones all help.
If low mood is persistent, deepening, or affecting daily life, please speak to your GP. Effective support is available and asking early is a strength.
Yes. Wanting to understand your diagnosis and feel heard is reasonable, and a second opinion is a normal part of healthcare, not a criticism of anyone. You are entitled to ask your clinician to explain your scan and the reasoning, what the alternatives are, and what happens if you do nothing.
If you are still unsure, another shoulder specialist's view is a legitimate next step. Bring your imaging and a written list of questions, and be specific about your goals and what the shoulder stops you doing.
Most shoulder problems are not dangerous, but a few warning signs deserve prompt attention: an unexplained lump that is enlarging, deep or larger than a few centimetres; constant pain at rest and at night that is steadily worsening; feeling generally unwell with weight loss, fevers or night sweats; a sudden inability to lift the arm after an injury; signs of wound infection after surgery (a firm, warm, enlarging or increasingly tender area, spreading redness, discharge or fever); signs of a possible blood clot (new calf pain or swelling, or chest pain or breathlessness); or pain not relieved at all by your prescribed medication.
If you are worried, contact your GP or, after surgery, your surgical team. If you are acutely unwell, use NHS 111 or urgent care.
