When can I stand after surgery?
Many patients stand on the day of surgery or the next morning with supervision and an appropriate walking aid.
How long will I stay in hospital?
Discharge depends on general health, wound condition, pain control and the ability to walk and use stairs safely.
When can I walk independently?
Support is reduced as strength, balance and gait improve. The rehabilitation team should guide the transition.
When can I start bending the knee?
Range-of-motion work usually begins early. Progress should be gradual and should not involve forceful unsupervised stretching.
Why is full extension important?
A knee that straightens well supports an efficient gait. Swelling control, positioning and prescribed exercises help restore extension.
Is postoperative pain normal?
Pain is expected early and should gradually decrease. Sudden worsening, calf pain or an abrupt loss of movement requires assessment.
How long can swelling last?
Swelling is common for weeks and can recur after activity for several months. Elevation and the prescribed exercise plan may help.
Is fever normal?
A mild early temperature rise can occur. Persistent fever, chills, wound discharge or increasing redness requires prompt contact with the clinic.
When are sutures removed?
The timing depends on the closure method and wound healing. Follow the discharge instructions and scheduled wound review.
When can I shower?
Shower only when the wound-care instructions allow it. Avoid soaking the incision until it is fully healed.
When can I use stairs?
Stair practice often begins before discharge. Use the handrail and the sequence taught by the rehabilitation specialist.
When can I stop using crutches?
The decision depends on loading permission, knee control and gait. Do not stop if this causes instability or marked limping.
When can I stop using a cane?
A cane can be discontinued when walking is stable, knee control is adequate and the care team agrees.
When can I use an exercise bike?
A stationary bike may be introduced when the wound is healed and sufficient knee flexion is available. Resistance should begin low.
When can I drive?
Driving requires adequate control, reaction time and freedom from sedating medication. The operated side and vehicle type matter.
When can I return to work?
Desk work may resume earlier than physically demanding work. Discuss duties, travel and safe restrictions with the surgeon.
How should I sleep?
Use a comfortable position that does not twist the knee. Do not keep a pillow permanently under the knee unless specifically instructed.
Can I kneel after replacement?
Some people can kneel after healing, but it may remain uncomfortable. Discuss timing and technique before trying.
Is clicking normal?
Mechanical sounds can occur in an artificial joint. New clicking with pain, swelling or instability should be assessed.
What causes stiffness?
Preoperative stiffness, swelling, scar tissue and inconsistent rehabilitation can all contribute. Early review is important if motion stops improving.
What range of motion should I expect?
The final range varies. The practical goals are safe walking, transfers, stairs and daily activities rather than a single universal number.
How far should I walk?
Start with short, frequent walks and increase gradually. More is not always better if swelling and pain rise afterward.
Which sports are suitable?
Low-impact activities are commonly preferred after recovery. High-impact and contact sports should be discussed individually.
Which symptoms require urgent review?
Increasing redness, wound drainage, high fever, severe calf swelling, chest pain or sudden shortness of breath requires urgent medical attention.
How long does rehabilitation take?
Meaningful improvement occurs over weeks, while strength and confidence may continue improving for many months.

Consistent rehabilitation and appropriate load progression are more important than comparing recovery dates with another patient.
