Condition
Knee Arthritis
Knee osteoarthritis causes pain on walking and stairs, stiffness, swelling and sometimes deformity. Treatment is staged, from physiotherapy and injections through to partial or total knee replacement when symptoms demand it.
Understanding the wear pattern
The knee has three compartments, and arthritis often affects them unevenly. Where wear is confined to one compartment, options such as partial knee replacement become available. Standing x-rays, and occasionally MRI, map the pattern of wear and shape the treatment plan.
Watch: what is knee osteoarthritis?
In this short video from his Doctify profile, Paddy Subramanian explains what knee osteoarthritis is, how it progresses, and the treatment options available at every stage.
Treatment without surgery
Strengthening the muscles around the knee remains one of the most effective treatments at any stage of arthritis. Combined with activity modification, weight management, bracing where appropriate and judicious use of injections, many patients postpone or avoid surgery altogether.
Surgical options
When non-surgical measures no longer control symptoms, the choice lies between partial and total knee replacement depending on the pattern of wear, ligament integrity and your goals. Paddy Subramanian will show you your own imaging and explain honestly which option, if any, is right for you.
