Mobility Aids After Knee Replacement: What You’ll Need in 2026

Getting the right mobility aids after knee replacement makes a real difference to your comfort, safety, and confidence at home. Yet many patients only think about equipment a few days before surgery. Some only realise what they need after they get home.

This guide covers every mobility aid you are likely to need after knee replacement. We explain when to use each one, what the NHS provides for free, and what you may need to buy. A full checklist with current UK prices is included so you can prepare in advance.

Why Do You Need Mobility Aids After Knee Replacement?

Everything you need after knee replacement – walking aids, bathroom equipment, and swelling management tools with current UK prices.

After knee replacement surgery, your new joint needs time to heal. Your leg will be swollen and stiff. For the first six weeks, you need support while walking and help with daily tasks that require bending, reaching, or standing for long periods.

The right mobility aids after knee replacement reduce your risk of falls. Falls in the first weeks can cause serious injury, including damage to the new joint. Equipment also helps you stay independent without relying on others for every task.

Your occupational therapist (OT) will assess your situation before discharge. They will recommend specific aids based on your mobility, home layout, and whether you live alone.

 

What Walking Aids Will You Need?

Walking aids are the most important mobility aids after knee replacement. You will use them every day for at least six weeks.

Walking frame (Zimmer frame)

Most patients start with a walking frame immediately after surgery. The frame provides maximum support while your leg is at its weakest. You will use it to walk short distances in hospital and at home during the first one to two weeks.

Walking frames are lightweight and adjustable. The NHS normally provides one before discharge at no cost. Private purchase costs £20 to £40.

Elbow crutches

Most patients progress from a frame to elbow crutches at around one to two weeks. Crutches allow you to walk further and faster while still protecting the operated leg.

You will use two crutches for approximately four to six weeks. After that, you may drop to a single crutch. The crutch goes on the opposite side to your new knee and moves forward at the same time as your operated leg.

The NHS usually provides crutches at discharge. Private purchase costs £15 to £30 per pair.

Walking stick

By six to eight weeks, many patients transition to a walking stick. A stick gives light support and confidence while you rebuild strength and balance. Some people use a stick for several months; others stop sooner.

A standard adjustable walking stick costs £5 to £15. Folding sticks cost around £10 to £20.

What Equipment Helps With Swelling and Pain?

Swelling is one of the biggest challenges after knee replacement. The right equipment helps you manage it effectively.

Ice packs and cold therapy wraps

Icing your knee regularly in the first six weeks reduces swelling and pain. Reusable gel ice packs cost £5 to £15. Cold therapy wraps that fit around the knee are more convenient and cost £15 to £30.

Apply ice for 15 to 20 minutes at a time, several times a day. Always wrap ice in a cloth to protect your skin.

Cold therapy machines (cryotherapy)

A cold therapy machine circulates chilled water around your knee through a wrap. These provide more consistent and effective cooling than ice packs. They are popular with private knee replacement patients.

Cold therapy machines cost £80 to £200 to buy. Some companies offer rental at £30 to £50 per week. They are not provided by the NHS.

Elevation cushion or wedge

Elevating your leg above heart level helps reduce swelling. A foam leg elevation wedge keeps your knee supported and comfortable. Cost: £15 to £30.

You can also use stacked pillows, but a purpose-made wedge is more stable and maintains the correct angle.

What Bathroom Aids Do You Need After Knee Replacement?

The bathroom can be challenging after knee replacement. Bending, standing on a wet surface, and getting on and off the toilet all require care.

Raised toilet seat

A raised toilet seat adds four to six inches to your toilet height. This makes sitting down and standing up easier while your knee is stiff and swollen. Versions with handles provide extra stability. Cost: £15 to £40.

Some NHS trusts provide raised toilet seats on loan. Ask your OT before discharge.

Shower stool

A shower stool allows you to sit while washing. This is safer than standing on a wet surface with reduced balance. Cost: £20 to £40.

If you have a bath rather than a walk-in shower, a bath board sits across the top of the bath. Cost: £15 to £30.

Grab rails

Grab rails beside the toilet, shower, or bath provide secure handholds. Screw-in rails are the most secure option. Cost: £10 to £25 each plus fitting.

The NHS may fit grab rails through a community OT referral. Waiting times vary. A local handyman can fit them for £30 to £60 per rail including fitting.

What Other Equipment Helps After Knee Replacement?

Several smaller items make daily life easier during recovery.

Long-handled reacher or grabber

A reacher lets you pick up objects from the floor without bending your knee excessively. Also useful for reaching items on high or low shelves. Cost: £5 to £10.

Long-handled shoe horn

Putting on shoes is difficult when your knee is stiff. A long-handled shoe horn lets you slip into shoes without excessive bending. Cost: £3 to £8.

Sock aid

A sock aid helps you pull on socks without bending your knee fully. Most patients get the hang of it within a day or two. Cost: £3 to £7.

Perching stool

A perching stool has a forward-sloping seat that lets you sit at kitchen worktops or bathroom basins while your knee recovers. It is height-adjustable and lightweight. Cost: £30 to £60.

What Does the NHS Provide for Free?

NHS provision of mobility aids after knee replacement varies by hospital trust and area.

• Usually provided: Walking frame and elbow crutches. These are given before discharge.
• Sometimes provided: Raised toilet seat, shower stool, bath board, long-handled reacher. These depend on your OT assessment and local stock.
• Rarely provided: Walking stick, sock aid, shoe horn, perching stool, ice packs, cold therapy machines, elevation cushions. You will usually need to buy these.
• Available via referral: Grab rails and home adaptations through a community OT referral. Fitting can take several weeks.

 

If you are having private knee replacement, your hospital OT will give the same advice. However, private hospitals do not typically loan equipment. Buy or arrange your aids before surgery.

How Long Will You Need Mobility Aids After Knee Replacement?

Recovery timelines vary, but here is a typical progression.

• Week 1 to 2: Walking frame at home. Crutches for longer distances if confident.
• Week 2 to 6: Two crutches for most activities. You may drop to one crutch towards the end.
• Week 6 to 12: One crutch or a walking stick. Most people stop using crutches by eight to ten weeks.
• Beyond 12 weeks: Many patients stop using aids entirely. Some keep a stick for longer walks or uneven ground.
