Step 1 - Your pre-operative assessment

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.

What will happen at the pre-assessment?

Blood tests, ECG, and chest X-ray

A full pre-operative screen including full blood count, kidney function, and clotting.

Medication review

Blood thinners, anti-inflammatory drugs, and immunosuppressants (if taken for rheumatoid arthritis) may need to be adjusted before surgery.

Anaesthetic discussion

General anaesthesia with an interscalene nerve block is usual. The block provides excellent pain relief for the first 12–18 hours after surgery.

Dental check

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.

Prepare your home

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.

The day of surgery

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.

Arrive at the time given

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.

Consent and marking

Your surgeon will confirm the procedure, mark the operative side, and you will sign a consent form before going to theatre.

Anaesthetic

You will meet the anaesthetist in the anaesthetic room. Once anaesthesia is established, the procedure will begin.

Recovery room

After surgery you will wake in the recovery room where nurses monitor your vital signs until you are stable and comfortable.

In hospital

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.

Pain control

You will be given oral pain relief before discharge. Take it regularly for the first 48 hours rather than waiting until pain is severe.

Wound check and dressing

A nurse will check the wound before you leave and explain how to keep it clean and dry.

Discharge letter and follow-up

You will receive a letter for your GP and details of your next outpatient appointment - usually at 2 weeks for a wound check.

You must not drive yourself home

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.

Going home

⚠️ 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.

Keep the wound clean and dry

Avoid getting the wound wet until it is fully healed - usually 10–14 days. Use a waterproof cover or cling film when showering.

Take your pain relief as prescribed

Do not wait until pain is severe before taking medication. Regular simple analgesia (paracetamol, ibuprofen if appropriate) is more effective.

Attend your wound check appointment

This is usually 2 weeks after surgery. Sutures or clips will be removed if used.

When to contact the hospital

Seek urgent advice if you develop increasing redness, warmth, swelling, discharge from the wound, or a temperature above 38°C - these may indicate infection.

Recovery week by week

2–4 weeks before surgery

Pre-assessment and home preparation

Full medical assessment, dental check, medication adjustment, and arranging home support.

Day of surgery

Surgery and inpatient stay

The procedure takes 1.5–2.5 hours. Most patients stay 1–2 nights in hospital.

Weeks 1–6

Sling and pendulum exercises

The arm is supported in a sling. Gentle pendulum exercises help prevent stiffness.

Weeks 6–12

Active physiotherapy

Strengthening exercises begin. Return to driving is usually possible around 8 weeks.

9–12 months

Full recovery

Full recovery, including return to overhead activities and sport, typically takes 9–12 months.

Common questions

How long will I wear a sling?

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.

When can I drive?

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.

Can I sleep in a bed?

Many patients find sleeping slightly reclined easier in the first week or two. A recliner chair or wedge pillow may be helpful.

What are the long-term restrictions?

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.

Common questions

Your questions, answered

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.

This procedureWhat can I expect afterwards, and how long does it last?

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.

Implant lifeWill the replacement wear out?

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.

PreparingHow can I prepare, and what should I ask my surgeon?

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.

AnaesthesiaWhat is a nerve block, and what happens when it wears off?

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.

Pain & sleepHow will I sleep, and how long will I be in the sling?

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 & medsWhat can I take for pain, and what if I cannot tolerate strong painkillers?

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.

Wound & scarsHow do I look after the wound and scars, and when can I shower?

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.

Getting backWhen can I drive and return to work?

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.

WellbeingIs it normal to feel low during recovery?

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.

Sources  General clinical guidance
Your choiceCan I ask for a second opinion?

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.

Sources  General clinical guidance
UrgentWhen should I seek urgent help?

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.
