How to Sleep After a Hip Replacement: Positions and Tips

Sleep is often one of the biggest frustrations in the early weeks after a hip replacement. You are tired, your body needs rest to heal, and yet finding a comfortable position that also respects your hip precautions can feel almost impossible. Many people describe the first week or two as the hardest part of the whole recovery, simply because of broken nights.

The good news is that sleep does improve, usually steadily, as pain settles and your hip grows stronger. This guide explains the safest sleeping positions, how to protect your new hip overnight, how to get in and out of bed without twisting, and what to do when pain wakes you in the small hours.

Why sleep is so difficult at first

There are a few reasons sleep is disrupted early on. Your hip is sore and swollen, your usual position may now be off limits, and you cannot move freely to get comfortable. Pain relief can wear off in the night, and some people find their mind races with worry about doing the wrong thing.

There is also the simple fact that you are likely less active than usual, so your body is not as physically tired as it once was. Combine that with the natural anxiety of a major operation and it is no wonder the nights feel long.

All of this is normal and temporary. Understanding the rules of safe positioning takes away a lot of the anxiety, which in itself helps you settle. The goal in these early weeks is not perfect sleep, which may not be realistic for a little while, but enough rest to support your healing.

The safest position: on your back

For most people, especially in the first few weeks, sleeping on your back is the safest and most comfortable choice.

Lying flat keeps your hip in a neutral position and makes it far harder to accidentally cross your legs or twist. To protect the joint, place a pillow between your knees and ankles. This stops your operated leg from drifting inwards across the midline of your body, which is one of the movements your team will have asked you to avoid.

Keeping a pillow between the knees matters because it guards against the leg rolling inward and the hip turning in ways that the precautions warn against. Our hip replacement precautions guide explains why these movements are restricted and for how long.

If swelling is troubling you, a pillow under the calf to gently raise the lower leg can help, as long as it does not bend the hip too far. Our guide on swelling after hip replacement has more on this.

Avoid the operated side early on

In the early weeks, you should usually avoid lying on your operated side, as it puts direct pressure on the healing joint and wound and can be painful.

Some people find lying on the non-operated side acceptable, but only if their surgical team agrees, and only with a firm pillow (ideally a couple of pillows) held between the knees and the full length of the legs. This keeps the top leg supported and stops it dropping forward across the body. Without that support, side-lying can pull the hip into a forbidden position, so never attempt it without proper padding.

Many surgeons prefer you to stay on your back until they are confident the hip is stable. When in doubt, back-sleeping with a pillow between the knees is the simplest and safest default.

Getting in and out of bed safely

Moving in and out of bed is where many people accidentally breach their precautions, so it is worth practicing a careful technique.

Getting in: back up to the bed until you feel it behind your knees. Sit down on the edge, keeping your operated leg out in front of you. Then, leading with your bottom, shuffle back and lower yourself down while lifting both legs onto the bed together. Keep your knees apart and avoid twisting your trunk. A slippery sheet or a smooth board across the bed can help your legs glide.

Getting out: reverse the process. Shuffle toward the edge, keeping your legs slightly apart, swing both legs down together without rolling onto your operated hip, and push up to sitting using your hands. Take a moment to steady yourself before standing.

A higher bed makes all of this easier, as you avoid bending the hip too far on the way down. If your bed is low, a firmer mattress or a mattress raiser can help. Some people find it easier in the early days to sleep downstairs in a suitable bed to avoid stairs altogether, then move back upstairs once they are steadier.

Take your time with these movements. There is no prize for being quick, and rushing is exactly when accidental twists happen. Slow, deliberate, well-rehearsed steps keep your new hip safe.

Managing pain through the night

Pain that wakes you is common in the first weeks, and a few simple habits make a real difference.

Time your pain relief. Ask your team about taking your medication so that a dose is working through the night. Taking pain relief shortly before bed, rather than waiting until pain wakes you, often gives a smoother night.

Wind down gently. A calm hour before bed, dim lighting, and avoiding screens help signal to your body that it is time to rest. A warm (not hot) drink can be soothing.

Get comfortable before you settle. Arrange your pillows, position your supportive pillow between your knees, and make sure anything you might need, such as water, a phone, and your tablets, is within easy reach so you do not have to twist or stretch.

Keep moving in the day. Gentle, regular activity and your prescribed exercises help tire you in a healthy way and reduce stiffness, which makes sleep come more easily. Avoid long daytime naps that eat into your night.

Use heat or ice as advised. Some people find a covered ice pack on the hip before bed soothes soreness, while others prefer gentle warmth on the surrounding muscles. Ask your team what suits your situation, and never apply ice directly to the skin or over a fresh wound.

If you do wake in the night, try not to clock-watch or grow frustrated, as that only makes it harder to drift off again. Resettle your pillows, breathe slowly, and remind yourself that simply resting your body still does it good, even if you are not fully asleep.

If pain is severe, persistent, or getting worse rather than better, speak to your surgical team or primary care doctor rather than simply enduring it.

Helpful equipment

A few inexpensive items can transform your nights. A firm contoured leg pillow holds your knees apart reliably, far better than a soft pillow that flattens. A bed rail or grab handle gives you something secure to push against when getting up. A backrest or wedge can make sitting up in bed easier if you read before sleep. Our guide to the best products for hip replacement recovery covers these in more detail.

Be patient: it does get better

Sleep is one of those things that improves almost without you noticing. As pain fades and your confidence grows, you will find positions come more easily and you wake less often. Within the first month or two, most people are sleeping far better than they did in those difficult opening nights.

For a sense of how the wider recovery unfolds, our hip replacement recovery timeline sets out what to expect week by week. In the meantime, stick to your back, keep that pillow between your knees, and trust that rest, like everything else in this recovery, returns with time.
