The discharge paper after a knee replacement is the document that matters at home. NHS knee replacement care expects people to move, with physiotherapy, inside limits the surgical team has set. Those limits cover how the person may walk, how much the knee should be asked to bend, and which movements wait. A family article cannot add a flexion target in degrees. If the paper names one, follow that number and ask the therapist to show what it looks like in the chair you have.
Pain, swelling, and tiredness are common in the early weeks. A sudden change in the pain, a new tightness that was not there yesterday, or a knee that will no longer do the movement it managed at the last visit needs a call to the treating team. Steady soreness that matches what the ward described is a different message from pain that jumps, wakes the person at night for the first time, or arrives with fever.
The house the person is coming back to
A firm chair with arms is easier to stand from than a low floor seat. The arms take some load while the operated knee learns to share the work. If meals happen on the floor, ask the therapist whether a chair should be used for the weeks they specify, and where it should stand so the path from bed to chair is clear.
Low soft sofas swallow the hips and make standing a heave. A plastic chair can work if it is stable, high enough, and has arms. A folding chair that rocks is a poor choice while balance is still returning. The therapist should see this setup, including the toilet and any step at the doorway. Advice drawn on a hospital corridor often changes once they see the actual seat.
Mobility aids explains why a walker or cane has to be the right height. Borrowing one that forces the person to lean is a common reason practice hurts more than it should.
Walking and bending stay inside the paper
Walk as the surgeon and physiotherapist instructed. Some people are asked to take weight through the leg early. Others have a restriction. The phrase on the paper wins over a relative's memory of "they told the patient in the next bed to walk normally."
Bending the knee is part of many recovery plans, and it is also a source of argument in families. The physiotherapist shows the movement, the range they want attempted, and the point at which forcing it becomes harmful. Stop if pain is sharp, if the person feels dizzy or breathless, or if the wound pulls in a new way. Physiotherapy at home is the right place to rehearse that teaching with the helper present.
Avoid twisting the knee to reach for something beside the chair. Move the object, or move the whole body, so the foot and knee point the same way. Small twists during dressing are a frequent source of a bad afternoon.
NHS information on deep vein thrombosis describes leg swelling and pain, and the breathlessness or chest pain that can follow if a clot reaches the lung. These symptoms are not a reason to "walk it off" or to add ankle exercises as treatment. Ankle movement is sometimes taught after surgery to keep the joint comfortable. It is not a remedy for a suspected clot.
Ice, elevation, and medicines
Use ice and raise the leg only if the team advised both, and only in the way they showed. A heavy ice pack directly on skin, or a leg propped so the knee is twisted, can create a new problem. If they did not mention ice, ask before starting it. Swelling that is expected looks different from swelling that is hot, one-sided in the calf, and paired with pain on standing.
Take the medicines that were prescribed, at the times written on the label. This article will not suggest a dose, an extra painkiller, or a blood-thinner schedule. If a dose is missed or vomiting stops the person keeping tablets down, call the clinic rather than doubling the next one.
Post-surgery care at home covers dressings, what a settled wound tends to look like, and the general warning signs after an operation. Read it beside the knee-specific paper, not instead of it.
What to record for the next visit
Note walking distance in the house, whether a helper was needed, and whether night pain is easing or growing. Mention any click or giving-way, any redness spreading past the dressing, and any day the person skipped practice because of fever or dizziness.
Progress after a knee replacement is often slower than families expect in week two, then more visible when swelling settles. The surgeon's limits do not expire because a relative is impatient. They change when the team changes them, in writing or in a visit where someone has looked at the knee.
