What to Expect During the First Week After Knee Replacement
The first week after knee replacement is usually the most demanding part of early home recovery. Pain, swelling, bruising, stiffness, sleep disturbance, fatigue and dependence on help are common. This does not mean the operation has failed.
The goal in the first week is safe walking, wound protection, swelling control, correct exercises, fall prevention, food and fluids, medicine clarity and knowing when to contact the treating team. Patients who have not reviewed discharge planning can read Hospital Stay After Knee Replacement.
What the First Week Is Really For
Learning safe transfers, short walks and correct use of the walker or walking aid.
Protecting the wound, keeping swelling under control and starting basic exercises.
Building confidence without overdoing activity or forcing painful bending.
First Day at Home
The first day at home should be kept simple. The patient should rest, walk only as advised, take medicines according to the discharge plan, keep essential items nearby and avoid unnecessary visitors or activities. A responsible adult should ideally be available, especially if the patient lives alone or feels unsteady.
Home Setup During the First Week
Keep medicines, water, phone, charger, ice pack, exercise sheet and contact details within reach.
Use a stable chair with armrests and avoid low sofas, floor sitting and deep bending positions.
Keep walkways clear, use night lighting and avoid carrying items while using a walker.
Pain During the First Week
Pain often fluctuates during the first week. It may increase when the nerve block wears off, after walking, during exercises or at night. The purpose of pain control is to allow rest, walking and physiotherapy. Pain that is steadily worsening rather than gradually settling should be reviewed. Read Pain After Knee Replacement Surgery.
Swelling and Bruising During the First Week
Swelling may involve the knee, thigh, calf, ankle and foot. Bruising can move down the leg and change colour. Swelling often increases toward evening or after activity. Elevation, activity pacing and cold therapy when advised may help. Read Swelling After Knee Replacement.
How to Elevate the Leg
Elevation is usually more useful when the lower leg and ankle are supported and the knee is not kept bent for long periods. A pillow only behind the knee can make straightening harder. The position should be comfortable and should not cause pressure, numbness or worsening pain.
Cold Therapy During the First Week
Cold therapy may reduce pain and swelling when used as advised. It should not be placed directly on skin, used over numb skin without caution or kept on while sleeping. The patient should follow the hospital’s instructions for frequency and duration.
Wound and Dressing Care
The dressing should remain clean, dry and secure according to discharge instructions. Do not apply powders, antiseptics, oils, creams or home remedies unless prescribed. The dressing should be checked if it becomes wet, loose, heavily stained or begins leaking. Read Wound Care After Knee Replacement.
Walking During the First Week
Short, regular walks are usually better than one long walk. The patient should use the prescribed walking aid, wear safe footwear, avoid pivoting on the operated leg and turn with small steps. Walking should build confidence without creating major next-day swelling or pain.
How Much Walking Is Too Much?
Too much walking may show up as a large increase in swelling, heaviness, night pain, limping, reduced knee movement or exhaustion. The answer is usually not complete bed rest but better pacing: shorter walks, planned rest, elevation and controlled exercise quality.
Exercises During the First Week
Ankle pumps support circulation and can be done frequently as advised.
Quadriceps tightening helps wake up the thigh muscle and reduce knee buckling.
Heel slides, supported bending and knee-straightening work should be controlled, not forced through severe pain.

Why Knee Straightening Matters Early
A knee that remains bent may make walking harder and increase limping. Bending is important, but knee straightening should not be ignored. Patients should avoid prolonged resting with the knee supported only in a bent position unless specifically advised.
Bathing and Toilet Safety
Bathing depends on the dressing and wound instructions. Avoid slipping, twisting, rushing, low seating and unsupported standing. A raised toilet seat, stable chair, caregiver assistance or bathroom modifications may be useful depending on the home setup and patient balance.
Stairs During the First Week
Use the stair method taught in hospital. Avoid repeated stair use unless necessary. Stairs should be performed slowly, with a railing or support, and preferably with supervision if the patient is still weak, dizzy or uncertain.
Sleeping During the First Week
Sleep disturbance is common because of pain, swelling, medicine timing, anxiety and difficulty turning. Patients should prepare the bed area, keep the walking aid nearby and use safe lighting for bathroom visits. Read Sleeping After Knee Replacement.
Food, Fluids and Constipation
A balanced diet with protein, fibre, fruit, vegetables and adequate fluids supports recovery. Constipation is common because of reduced activity, pain medicines and routine changes. The discharge plan should be followed, and persistent problems should be discussed rather than ignored.
Fatigue and Mood Changes
Tiredness, irritability, low mood and frustration are common in the first week. The patient has undergone major surgery, sleep is disrupted and independence is reduced. Reassurance, planned help and realistic expectations are important during this period.
What Not to Do in the First Week
Do not stop the walking aid early just to appear ahead of schedule.
Do not force deep bending, squat, sit on the floor or do unsupervised heavy exercise.
Do not ignore wound drainage, rapidly increasing swelling, repeated buckling or severe worsening pain.
When to Contact the Treating Team
Contact the treating team when pain, swelling, wound staining, walking difficulty, medicine side effects or general recovery seems to be worsening rather than gradually settling. Emergency symptoms should be handled through urgent medical services rather than home management.
Frequently Asked Questions About the First Week
How much pain is normal?
Pain is expected, especially with movement. It should be manageable with the prescribed plan and should not steadily worsen every day.
How often should I walk?
Short, regular, safe walks are usually preferred over long walks. The exact plan depends on the patient’s condition and surgeon’s advice.
How much should my knee bend?
There is no universal first-week number. Swelling, pain, preoperative stiffness and muscle control all influence early movement.
Can I sleep on my side?
Yes, when comfortable and safe to turn, but pillows may be needed to support the leg and avoid twisting.
Is bruising normal?
Bruising is common and may move down the leg. Review is needed when it is associated with major swelling, wound problems or sudden deterioration.
