Is knee osteoarthritis safe in older adults?

Knee osteoarthritis develops when the tissues that help a joint glide and absorb load change over time. It may cause pain with walking or stairs, stiffness after rest, reduced confidence, or difficulty standing from a chair. The severity of symptoms does not always match an image, so assessment considers movement, strength, function, sleep, falls risk, and the person’s goals.

Older adults may also have heart, kidney, stomach, vision, or balance problems that influence medicine and exercise choices. A clinician can review these factors before recommending pain relief, walking aids, strengthening, weight-management support, injections, or an operation. Gentle, progressive activity can help preserve function, but a sudden flare or new symptom should not automatically be attributed to arthritis.

Use a stable surface and supportive footwear, and consider a walking aid assessment if the knee gives way or balance is uncertain. Physiotherapy can work on thigh and hip strength, flexibility, stair technique, and confidence with daily tasks. Break demanding activities into manageable periods and change position regularly. Take medicines only as prescribed, especially if you have kidney disease, stomach ulcers, heart problems, or take blood thinners. Keep a record of pain, swelling, walking ability, and falls.

Seek prompt assessment for a hot, very swollen, or suddenly painful knee, especially with fever or feeling unwell. Get medical advice after a fall if you cannot bear weight, the knee looks deformed, or movement is suddenly restricted. Urgent care is needed for new calf swelling with chest pain or breathlessness, or for a leg that becomes cold, pale, numb, or weak.
