What Do I Need at Home After Knee Replacement?

Most people ask this question as a shopping list, and it is really a layout question. What you need at home after a knee replacement is less about owning particular objects and more about arranging the rooms you will actually use so that the new knee is not asked to bend, twist, or lower you further than it can manage in the first few weeks.

The useful way to think about it: for the first two to three weeks you will spend almost all day in one chair, sleep in one bed, use one bathroom, and cross one or two doorways. Set those four places up properly and you will need surprisingly little else.

This guide goes room by room. It also says plainly which items the hospital usually gives you, because buying a frame or crutches you are about to be handed for free is the most common wasted purchase.

First, what the hospital usually provides

Do not buy these until you have asked. In the UK, and in most US hospital and rehab discharge plans, the surgical team or physical therapist typically issues:

• A walking frame, crutches, or both. You will be walking with them before you leave the ward.
• Compression stockings, often two pairs, with instructions on how long to wear them.
• An ice pack or cold wrap, though the one you are given is often basic.
• Sometimes a raised toilet seat or a perching stool, depending on your health service, your assessment, and local stock.

Ask your pre-op assessment nurse the direct question: what will I be sent home with, and what am I expected to buy? A five-minute conversation there saves more money than any comparison shopping.

The chair you will live in

This is the single most important thing in the house, and it is free to get right.

You want a firm, high seat with two armrests. Low, soft sofas are the enemy: a deep seat forces the knee past the angle it can comfortably bend and gives you nothing to push up from. A dining chair with arms often beats an expensive armchair.

Test it before your operation. Sit down and stand up ten times. If you are hauling on the furniture or rocking to build momentum, the seat is too low. A firm cushion raises the seat height by a useful few inches and costs very little.

Set up next to that chair, within arm’s reach without standing: a small table, your phone charger, water, medication, the TV remote, and tissues. Every trip you avoid is one you do not have to make on a painful knee.

You will also want somewhere to put the leg up. Elevation is not optional after a knee replacement, it is how the swelling drains, and a footstool that only reaches your calf is not enough. The leg needs to be supported along its length with the ankle above the level of the hip.

The bathroom

The bathroom is where the falls happen, and it is worth more attention than any other room. Our full guide to preparing your bathroom before joint replacement covers the layout in detail, but the short version for a knee is:

A raised toilet seat is the item people are most consistently glad they bought. A standard toilet asks the knee to bend to roughly 90 degrees and take your full body weight on the way down and the way back up. A riser of four or five inches removes most of that. Versions with arms give you something to push through instead of grabbing at a towel rail.

Somewhere to sit in the shower. A stool or bench means you are not standing on a wet floor balancing on one leg. If you have a bath with a shower over it, a bath board or transfer bench is the safer answer, because stepping over the rim of a bath is one of the hardest movements in the house after a knee replacement.

A long-handled sponge lets you wash your lower leg and foot without bending the knee.

A non-slip mat inside the shower or bath, and a second one outside it.

The bedroom

Getting in and out of bed is harder than people expect, because the operated leg cannot lift itself in the first days. Two things help.

A bed at the right height. You want to be able to sit on the edge with both feet flat on the floor and your hips slightly higher than your knees. A bed that is too low is hard to stand up from; too high and you drop onto the leg. Most beds are fine, but if yours is very low, bed risers are a cheap fix.

Something to pull or push against. A bed rail or grab handle that slides under the mattress gives you a fixed point to lever yourself up with, rather than twisting to grab the headboard. Our guide on how to get in and out of bed after surgery has the movement itself.

A leg lifter strap is worth considering if you struggle to swing the operated leg onto the bed. It is a simple loop you hook over the foot and pull with your hands, and for a few weeks it can be the difference between managing alone and calling for help.

For sleeping, most people are more comfortable on their back with the leg straight, not propped on a pillow under the knee. A pillow under the knee feels lovely and encourages the knee to stiffen in a bent position, which is the one thing your physical therapist will ask you not to do. Support under the calf and ankle instead. See how to sleep after knee replacement for the full picture.

The kitchen

You will be on crutches or a frame, which means you have no free hands to carry anything. That is the whole problem, and it has three answers.

Move what you use every day to waist height before the operation. Mugs, plates, cereal, the kettle. Anything at floor level or above shoulder height is effectively out of reach for a few weeks.

Fill the freezer. Ten meals you can heat one-handed is worth more than any gadget in this guide. Cooking is tiring, standing is tiring, and appetite is unpredictable in the first fortnight.

Get something to carry things in. A small backpack or a bag that hangs on the frame solves the no-free-hands problem for a few pounds. A trolley works well if your floors are level.

Getting around the house

Clear the routes first. Walk the path from your chair to the bathroom, and from the bathroom to the bed, with your eyes on the floor. Remove loose rugs, trailing cables, and anything you have to step over. The vast majority of post-operative falls are trips, not collapses.

Non-slip socks or firm slippers with a back to them. Backless slippers are a genuine hazard on stairs.

Think about the stairs before you come home. If your bathroom is upstairs and you cannot face the stairs on day one, plan a downstairs base. Most people can manage stairs from the start, one step at a time, good leg up and operated leg down, but it is much less stressful when you have decided in advance. See stairs after knee replacement.

For the swelling, which lasts longer than you think

Knee swelling is not a first-week problem, it is a first-few-months problem, and it is the main reason the knee feels tight and hard to bend. Two things are used daily by almost everyone.

A wrap-around ice pack that fits the whole joint, rather than a bag of peas that slides off. You will use it several times a day, especially after exercises, so having two so one is always frozen is more useful than having one expensive one.

Compression, if your team has advised it, using the stockings they gave you.

If you want to invest more, a cold therapy machine circulates chilled water through a wrap and holds a steady temperature for far longer than a gel pack. It is the one bigger purchase people who have had both knees done tend to say was worth it. Our best recovery tech for knee replacement guide covers those in detail.

What you can probably skip

Being honest about this is more useful than a longer list.

• A hospital bed. Almost nobody needs one for a routine knee replacement.
• A knee walker or scooter. These are for foot and ankle surgery, where you cannot put weight through the leg at all. After a knee replacement you are usually weight-bearing from day one.
• A second-hand CPM machine. Continuous passive motion machines have largely fallen out of favour, and the evidence for them is weak. Ask your surgeon before spending anything here.
• A full “hip kit” with a sock aid and long shoe horn. These are essential after a hip replacement, where bending past 90 degrees is forbidden. After a knee, most people can reach their feet within a week or two, awkwardly but adequately. Buy it if you already struggle to reach your feet, not by default.

The short answer

If you want the list stripped to what most people actually use every day:

A firm chair with arms. A raised toilet seat. Something to sit on in the shower. A wrap-around ice pack. Somewhere to elevate the leg properly. Non-slip footwear. A freezer with food in it.

Everything else is a comfort you can order later if you find you want it. Getting these in place before the operation means the day you come home is about resting, not about ordering things.
