Shoulder Replacement Precautions: Movements to Avoid While You Heal

In the weeks after a shoulder replacement, you will be given a short list of movements and activities to avoid. These are usually called shoulder precautions, and although they can feel limiting, they exist for one simple reason: to protect the repaired muscles and tendons around your new shoulder while they heal and grow strong. Following them is one of the most important things you can do for a smooth recovery. This guide explains the standard precautions, why they matter, how long they tend to last, and how to manage everyday tasks comfortably while you stick to them.

Because a shoulder replacement can be done in different ways, the exact instructions vary. A total shoulder replacement and a reverse shoulder replacement have slightly different restrictions, so your own surgeon’s advice always comes first. What follows is the general pattern most people are asked to follow.

The common precautions

While the exact wording varies between surgeons, most precautions come down to a few key restrictions in the early weeks.

Wear your sling as instructed. The sling holds the shoulder in a protected position and reminds you not to move it too far. Most people wear it most of the time, including in bed, for the first few weeks, removing it only for approved exercises and washing.

Do not actively lift or reach with the operated arm. In the early weeks the repaired muscles must not do the work of lifting. Avoid raising the arm under its own power, reaching up to high shelves, or stretching out for things until your team says you can.

Do not reach out to the side or behind your body. Movements that take the arm away from your body or behind your back put the most strain on the healing tissues. Keep the arm close to your side, and turn your whole body instead of reaching.

Do not bear weight or push through the arm. Do not use the operated arm to push yourself up out of a chair or bed, to lean on, or to carry anything. Even pushing up from a chair puts a surprising load through the shoulder.

Do not lift anything heavy. In the first weeks, many teams limit you to lifting nothing heavier than a cup or a light plate with the operated arm. Heavier lifting comes much later and only with clearance.

Why the precautions matter

A shoulder replacement relies on the muscles and tendons around the joint to hold it stable and move it. During surgery, some of these tissues are worked through or repaired, and straight afterward they have not yet regained their strength. Certain movements, particularly actively lifting the arm, reaching out or behind, or bearing weight through it, pull hard on these healing tissues.

If the repair is strained too soon, it can heal poorly or come apart, which slows recovery and sometimes needs further treatment. In a reverse shoulder replacement, certain positions can also raise the risk of the joint slipping out of place. The precautions simply steer you away from the handful of movements that carry this risk, so the shoulder can heal on a solid footing.

How long do they last

For many people the strictest precautions matter most for the first six weeks or so, with the sling often worn through that period. Assisted and passive movements usually happen during this time, active movement is added once the surgeon is happy the repair has healed enough, and gentle strengthening comes later still, often after twelve weeks.

This varies a great deal, and the type of replacement makes a real difference, so your own team will give you the timescale and the specific limits that fit your surgery. This is exactly why you should follow your own surgeon’s instructions rather than general advice or what a friend was told. Our shoulder replacement recovery timeline gives a sense of how the weeks tend to unfold.

Managing the sling

The sling can feel awkward at first, but it is doing important work. Wear it exactly as your team advises, including the times they want it on at night. Learn how to loosen and refasten it so you can wash and do your approved exercises, and check the fit regularly. If it rubs, feels too tight, or makes your hand tingle, adjust it rather than putting up with it, and a soft pad under the strap can ease pressure on your neck. Keep the elbow, wrist, and hand moving within the sling as your team allows, which keeps the whole arm from stiffening.

Getting dressed

Dressing one-handed is one of the first daily challenges. The simple rule is to dress the operated arm first and undress it last, so the shoulder does the least amount of moving. Loose clothing that opens at the front, such as a zip-up or button top, is far easier than anything you pull over your head. Our guide on the best products for shoulder replacement recovery suggests front-opening clothing and simple dressing aids that help. Take your time and let your good arm guide the operated one gently into a sleeve rather than reaching or twisting the shoulder.

Washing and everyday tasks

Reaching up to wash your hair or under the operated arm is difficult and often restricted, so a handheld showerhead, a long-handled sponge, and help from someone else in the first weeks all make washing easier and safer. Sit down to wash if standing tires you.

Around the house, keep everyday items at waist height so you are not reaching up or bending down, and use your good arm for tasks like opening doors and carrying light things. Avoid sudden reaches, and never use the operated arm to steady yourself or break a fall if you can help it. Preparing food, carrying a plate, or lifting a kettle should all be done with the good arm until your team clears the operated one.

Sleeping safely

Most people are advised to sleep propped up rather than flat in the early weeks, often in a recliner or against a firm wedge, with the operated arm supported on a pillow and the sling on as instructed. Lying on the operated shoulder is off limits until your team says otherwise, as it presses directly on the healing joint. Our guide on how to sleep after shoulder replacement covers comfortable positions that respect your precautions.

Easing back to normal

The precautions are temporary. As your follow-up appointments confirm the shoulder is healing well, your team will gradually lift the restrictions: first the sling comes off, then active movement returns, and later you build strength and reach for more. Doing the gentle work in our exercises after shoulder replacement guide is what rebuilds the muscles and ultimately makes the precautions unnecessary. For now, treat them as a short-term framework that protects all the good work your surgeon has done. If you are ever unsure whether a particular movement is allowed, ask your team rather than guessing.

Warning signs to take seriously

Alongside the precautions, know the symptoms that need prompt medical attention. Contact your surgical team, primary care doctor, or seek urgent care if you notice signs of infection, such as increasing redness, warmth, or swelling around the wound, fluid or pus leaking from it, a temperature, or pain that is getting worse rather than better. A sudden change in the shape of the shoulder, a new inability to move the arm, or severe pain after an awkward movement can signal that the joint has slipped or the repair has failed, and needs urgent care. New numbness, tingling, or weakness spreading down the arm, or a hand that turns cold, pale, or blue, should be checked straight away. And if you ever have sudden breathlessness, chest pain, or cough up blood, which can signal a clot on the lung, call the emergency services immediately.

When in doubt, it is always better to call your team and be reassured than to wait. They expect these calls and would far rather hear from you early.
