What are the signs that I need knee replacement?

Knee replacement may be considered when arthritis or joint damage causes persistent pain, stiffness, swelling, and difficulty performing normal activities. Common warning signs include pain while walking, climbing stairs, getting up from a chair, or standing for long periods. Some patients also experience pain while resting or at night.

Another important sign is when the knee becomes increasingly stiff or deformed and daily activities start becoming difficult. Patients may stop walking longer distances, avoid stairs, struggle to bend or straighten the knee, or begin depending heavily on pain medicines. Advanced arthritis may eventually cause severe cartilage loss, allowing the joint surfaces to rub against each other.

Knee replacement is usually not the first treatment. Doctors commonly consider medicines, physiotherapy, strengthening exercises, weight management, activity changes, walking aids, or injections when appropriate. Surgery becomes more relevant when these measures no longer provide enough relief and symptoms seriously affect quality of life. An X-ray alone does not decide whether surgery is necessary. Dr. Atul Mishra considers symptoms, examination findings, imaging, general health, age, activity level, and previous treatments before recommending knee replacement.
