One of the most common frustrations in the early weeks after a hip or knee replacement is not the walking or the exercises. It is sleep. Many patients are surprised by how disrupted their sleep is at first. It can be disheartening. The reassuring news is that it is normal, it is temporary and there is a good deal you can do to help.
Why sleep is disturbed at first
There are several reasons. The operated joint can ache at night, swelling tends to build up over the day and it can be hard to find a comfortable position. On top of that, you are usually moving less than normal during the day, which reduces natural tiredness. Pain medication can also affect sleep patterns. All of this settles as the joint heals.
After a hip replacement
Finding a comfortable position is the main challenge. Many patients are most comfortable on their back in the early weeks. If you prefer to lie on your side, a pillow between the knees helps keep the hip comfortable and well aligned but it will be uncomfortable to lie on your operated side. Follow any specific advice Mr Kosuge has given you about positions to favour or avoid in the early weeks, as this depends on your particular operation.
After a knee replacement
The instinct is to put a pillow under the knee to take the pressure off. It is better not to, because keeping the knee bent for long periods can make it harder to straighten the leg fully later, which is an important goal of recovery. Instead, keep the leg straight when resting. Elevating the whole leg and using ice as advised, helps bring down the swelling that causes much of the night-time ache.
Practical habits that help
Timing your pain relief so that it is working as you go to bed makes a real difference. A regular routine, a cool and dark room and gentle activity during the day all help. Avoid long daytime naps if you can, so that you are genuinely tired at night. Above all, be patient with yourself. Sleep improves steadily as the swelling and discomfort settle.
