Sex After a Hip Replacement: When It Is Safe and How to Protect the New Joint

Most people can return to sex around 6 to 8 weeks after a hip replacement, provided they keep within the same precautions that protect the new joint in everyday life: no deep bending past 90 degrees, no crossing the operated leg over, and no twisting it inward. It is one of the most common questions people have after this operation and one of the least asked out loud. I did not ask it at all before I went home, and I spent the first weeks guessing from a laminated sheet that covered toilet seats and car seats in great detail and the bedroom not at all. So here is the plain version, checked by Ms Raman.

When it is generally safe

Common guidance is to wait about 6 to 8 weeks, and then to follow your own surgeon’s advice. The NHS advises trying to avoid sex for 6 to 8 weeks after the operation ¹, and Versus Arthritis says that most people will probably be able to have sex after about six to eight weeks ². The American Academy of Orthopaedic Surgeons simply advises talking to your surgeon about when it is safe for you ³.

That window lines up with the rest of early recovery. The soft tissues around the new joint are still healing in the first weeks, which is the reason precautions exist at all and the reason dislocation, which happens in about 1 to 2 in 100 people, is most likely early on. It also lines up with the point where many people are off strong painkillers, sleeping better, and moving around the house with some confidence, which I describe in my week by week recovery timeline. Some people feel ready sooner and some much later. Both are normal.

Why the precautions still apply in bed

The movements that can dislocate a new hip are the same whether you are reaching for a sock or lying in bed, so the precautions you follow during the day apply here too. After a posterior approach, that usually means three things for roughly the first 6 to 12 weeks: do not bend the hip past 90 degrees, do not cross the operated leg over the midline of your body, and do not twist it inward. The reasoning behind each one is in hip dislocation precautions.

The approach matters. The AAOS notes that you may need to follow precautions during sexual activity and that what they are depends on the surgical approach used ³. After an anterior approach, some surgeons give fewer or different restrictions, and some give none; the differences are explained in hip replacement surgical approaches. This is why a friend’s advice, or this article, can only be a starting point. Your surgeon knows how your hip was put in.

Positions and practicalities

In the early weeks, the easiest positions are the ones that keep the operated leg supported, relaxed, fairly straight, and out of the movements on your precautions sheet. I am not going to draw diagrams, and Ms Raman would rightly tell me that the specifics belong with your own team, but the principles are simple:

• Support the operated leg. Pillows under or beside it stop it rolling inward or across.
• Avoid deep bending of the operated hip. Positions that bring the knee up towards the chest on that side are the ones to leave for later.
• Let the operated hip do less. Many people find it easiest at first for a partner to take the more active role.
• Keep the legs apart rather than crossed, in the same way a pillow between the knees protects you at night.
• Go slowly and stop if something hurts sharply. Some ache and tiredness are expected; a sudden sharp pain is a reason to stop and rest.

A partner who has read the precautions sheet is a real asset. Mine had absorbed the rules faster than I had and was more nervous about breaking them than I was, which, oddly, made it easier to talk about.

The emotional side

Feeling nervous, tired, or self-conscious about sex after a hip replacement is very common, and it usually eases as confidence in the new joint grows. For me, the fear was less about pain than about the hip itself: after weeks of being told what not to do, any movement outside the routine felt risky. The scar was another thing I felt oddly shy about at first.

What helped was the same thing that helped with everything else in recovery: building confidence in ordinary movement first. Once I could get in and out of bed, roll onto my good side with a pillow between my knees, and walk around the house without thinking about it, the idea of intimacy stopped feeling like a hazard. Talking about it openly, rather than tiptoeing around it, helped too.

It is also worth remembering why you had the operation. Hip osteoarthritis often makes sex painful or awkward, through stiffness and restricted movement, and for many people the long-term effect of a new hip is that intimacy becomes easier than it had been for years. My own sense of that came later, after the precautions had lifted, and I touch on what changes for good in daily life after hip replacement.

When to stop and get help

If the hip ever feels as though it has shifted or popped, if you cannot bear weight or move the leg normally, or if the leg suddenly looks shorter or turned, treat it as urgent and get seen the same day. Those are the signs of a possible dislocation, and they apply whatever you were doing when it happened. There is no reason to be embarrassed about how it happened; emergency teams have heard everything.

Short of that, new or increasing pain in the groin, thigh, or buttock that does not settle with rest, or anything that makes you worried about the wound, is a reason to contact your team rather than wait.

How to ask your team

The easiest time to ask is before you go home, and the easiest way is to ask it as a practical question like any other. Physiotherapists and surgeons are asked about sex after hip replacement all the time, and some hospitals have a leaflet on it. A simple “when can I return to sex, and are there positions I should avoid with my approach?” is enough. If you did not ask before discharge, your follow-up appointment or a call to the physiotherapy team is the next best time.

I wish I had asked. It would have saved me several weeks of guessing from a sheet that never mentioned it.

This is general information from my own experience, checked for accuracy, and not medical advice. When and how you return to sex after a hip replacement depends on your operation and recovery, so follow the advice of the surgeon and physiotherapist who treated you.
