Knee arthritis occurs when the cartilage and other structures within the knee joint gradually become damaged, leading to pain, stiffness, swelling, and difficulty with activities such as walking, climbing stairs, or exercising. Osteoarthritis is one of the most common forms of knee arthritis. Treatment depends on the severity of arthritis, symptoms, activity level, and overall health. Treatment options may include: - Exercise and physiotherapy - Weight management - Activity modification - Pain-relieving medicines when appropriate - Injections for selected patients - PRP treatment in appropriate cases - Bracing or walking aids when required - Joint-preserving procedures for selected patients - Total knee replacement for advanced arthritis when other treatments no longer provide adequate relief An orthopedic evaluation can help determine the extent of joint damage and identify the most suitable treatment approach.
