Why Knees Are Replaced
Advanced osteoarthritis wears away the cartilage cushioning the knee. When pain persists at rest, sleep is disturbed and walking distance shrinks despite medication, physiotherapy and injections, joint replacement restores the worn surfaces with metal and polyethylene components.
Week by Week
Day 1 to 2: you stand and take assisted steps with a walker, and knee-bending exercises begin. Day 3 to 5: most patients are discharged walking with support. Week 2: stitches or staples are removed and bending typically reaches 90 to 100 degrees.
Week 6: most people walk without support indoors and manage stairs one at a time. Month 3: driving, long walks and normal daily routine are usually comfortable. Improvement in strength continues up to a year.
What Makes the Difference
Structured physiotherapy is the single biggest determinant of outcome. Blood sugar control, weight management and pre-operative quadriceps strengthening all shorten recovery.
Our orthopedic and physiotherapy teams work from a single rehabilitation plan so exercises continue seamlessly after discharge, including home-care physiotherapy where mobility is limited.
Frequently Asked Questions
How long does a knee implant last?
Modern implants commonly last 15 to 20 years or more depending on weight, activity level and bone quality.
Can both knees be done together?
Sometimes. It depends on age, heart and lung fitness and haemoglobin. Your surgeon will advise after assessment.
