Quick answer
The key tips after knee replacement: keep the wound clean and dry, sleep on your back without a pillow under the knee, use a raised toilet seat and a shower chair, pray on a chair at first, take blood-clot medication on time, prevent falls at home, do your exercises daily, and report fever, wound discharge or calf pain promptly.

Small daily habits make a big difference to recovery. These are the instructions we give our patients when they go home, as part of our guide to total knee replacement surgery.
Wound care
- Keep the dressing clean and dry until your surgeon allows showering.
- Do not apply creams or home remedies to the wound.
- Stitches or clips are usually removed after about two weeks.
- Report redness, increasing warmth or discharge promptly.
Sleeping, sitting and prayer
- Sleep on your back with the knee straight — never a pillow under the knee.
- You may sleep on the other side with a pillow between the knees.
- Use a firm chair with arms, not a low sofa.
- Pray seated on a chair in the early weeks; kneeling comes later, if comfortable.

Bathroom, stairs and the car
- A raised toilet seat and a shower chair make the first weeks easier and safer.
- On stairs: up with the good leg, down with the operated leg, holding the rail.
- Get into the car seat first, then swing the legs in; driving usually after 4–6 weeks.
Key numbers to know
- Across 18 randomised trials (1,739 patients), physiotherapy improved function and pain at 3–4 months after knee replacement, and home exercise worked as well as clinic sessions (Artz et al., 2015).
- In the best-quality studies, about 20% of patients reported troublesome long-term pain after knee replacement (10%–34% across studies) (Beswick et al., BMJ Open 2012).
| Treatment | When we use it | What to expect |
|---|---|---|
| Conservative care: exercise, weight loss, topical pain relief | Grade 1–3 arthritis | Better pain and movement; many patients delay surgery |
| Joint injections (steroid, hyaluronic acid or PRP) | Persistent pain despite conservative care | Temporary relief that varies between patients |
| High tibial osteotomy (HTO) | Active patients under 60 with bow legs and arthritis on the inner side only | Realigns the leg and keeps the natural knee |
| Partial knee replacement | Arthritis limited to one compartment with healthy ligaments | Faster recovery and a more natural-feeling knee |
| Total knee replacement | Severe (grade 4) arthritis with pain limiting daily life | Pain usually resolves; walking on day 1–2 |
| Revision knee replacement | Loosening, infection or instability of a previous knee replacement | Bigger surgery with special components to restore stability |
At Prof. Dr. Ibrahim Shaarawi’s clinics in Nasr City, Mohandeseen and New Cairo (5th Settlement) we examine the knee and review standing X-rays at the same visit, then decide on conservative care, osteotomy, or a partial or total knee replacement according to the arthritis grade, your age and activity.
Protecting the new joint
- Take blood-clot prevention as prescribed and walk regularly.
- Tell any doctor or dentist about your knee replacement; treat infections promptly.
- Keep your weight down.
- Choose low-impact activities — walking, swimming, cycling — and avoid running and jumping.
For the full recovery timeline see knee replacement recovery time and for exercises exercises after knee replacement.
When to call your surgeon
- Fever, wound redness or discharge.
- Calf pain and swelling, or breathlessness (emergency).
- Severe or increasing pain, or a fall.
Normal pain and swelling are explained in pain after knee replacement, and walking advice in walking after knee replacement.
