Hip Replacement Precautions

What precautions are — and what they're for

Hip replacement precautions are temporary limits on certain positions in the early weeks of recovery. Their job is to protect the new hip from dislocating — slipping out of its socket — while the muscles and capsule around it heal and tighten back up. They're a short chapter of recovery, not a permanent way of life.

Why they depend on the surgical approach

The single biggest factor in which precautions apply is how the surgeon reached the hip:

• Posterior approach. The most common set of precautions goes with this approach — typically avoiding bending the hip past about 90 degrees, crossing the legs at the knees or ankles, and rotating the operated leg inward.
• Anterior approach. This approach often comes with few or no formal positional precautions, because of the way it preserves stability — though some surgeons still suggest a few. Your surgeon's guidance is what defines your limits.

Because of this, two people can leave the same hospital with very different instructions — and that's expected. A general guide can't replace the specific precautions your surgeon assigns.

The classic posterior precautions, in plain terms

• Don't bend too far. Keeping the hip from bending past roughly 90 degrees — so low chairs, deep squatting, and bending all the way down to the feet are avoided early.
• Don't cross the legs. Keeping the legs uncrossed, sitting and lying, often with a pillow between the knees.
• Don't rotate inward. Avoiding turning the operated foot and knee inward.

Living with precautions day to day

When precautions apply, a few simple tools make them easier: a higher chair or a firm cushion to avoid sinking into a deep bend, a pillow between the knees for sleeping, and reaching aids — a grabber, a long-handled shoehorn, a sock aid — so you don't have to bend down to your feet. Setting these up before surgery makes the first weeks smoother.

When precautions ease

When they're used, precautions are typically followed for the first several weeks — often around six weeks — while the tissues heal, then eased as your surgeon advises. As they lift, everyday movements gradually return to normal.

When to seek care

A dislocation is uncommon, and the precautions are designed to keep it that way — but it helps to know the signs: sudden severe hip or groin pain, the leg appearing shortened or turned, and difficulty moving the hip or bearing weight. That warrants prompt medical care. Fever, increasing redness or drainage from the incision, or calf pain and swelling are also worth contacting your surgeon's office about.
