What does knee osteoarthritis mean in older adults?

The knee may feel stiff after rest, ache with walking or stairs, or become less flexible. Some people notice grinding or swelling, while others have symptoms that vary from day to day. An X-ray appearance and the level of pain do not always match. Other problems can cause similar symptoms, so a clinician considers the history, examination, and overall health.

Treatment usually starts with a plan matched to strength, balance, mobility, and the activities that matter to you. Pacing, supportive footwear, exercises guided by a physiotherapist, and strategies for stairs can reduce strain while preserving movement. Medicines or injections may be discussed after checking other medicines and health conditions. If symptoms continue to limit daily life, ask about further options.

Arrange a review when pain steadily worsens, walking becomes less secure, sleep is disturbed, or the knee repeatedly swells. Seek urgent help after a fall if you cannot bear weight, or if the knee is hot and red with fever. New calf swelling, chest symptoms, or sudden breathlessness also require urgent attention.

Ask which findings support osteoarthritis, what exercise level is appropriate, and how to protect the knee without becoming inactive. Discuss pain relief alongside your other conditions, and ask when a reassessment or specialist opinion would be useful.
