How to Use the Knee Osteoarthritis Risk Checker
Knee osteoarthritis is a common joint condition where cartilage gradually wears down with age, causing pain and stiffness. This checker reviews 5 signs used clinically — age, stair pain, how long morning stiffness lasts, knee noise, and body weight — to sort risk into low, moderate, or high.
Age is the biggest risk factor, and whether morning stiffness eases within 30 minutes matters too. Osteoarthritis stiffness typically loosens within 30 minutes, while stiffness lasting longer raises the possibility of an inflammatory condition like rheumatoid arthritis instead.
Weight management, low-impact exercise like swimming or cycling, and strengthening the muscles around the knee all help with prevention and management. But if pain recurs or stairs become difficult, please don't ignore it — see an orthopedic specialist for an X-ray and a proper evaluation.
Frequently Asked Questions
Occasional painless knee cracking is usually normal. But if it happens often along with pain or swelling, it can signal cartilage wear from osteoarthritis — an orthopedic exam is worth getting.
Age is the biggest risk factor, but a past knee injury, excess weight, or repetitive knee strain (sports, squatting) can bring it on at a younger age too. If risk signs are present, a doctor visit is worthwhile regardless of age.
