Knee osteoarthritis is a degenerative joint disease characterized by the breakdown of cartilage in the knee joint, leading to pain, stiffness, swelling, and decreased mobility.
Common symptoms of knee osteoarthritis include pain, stiffness, swelling, decreased range of motion, crepitus (grinding or crackling sensation), and difficulty with activities such as walking, climbing stairs, or getting up from a chair.
Diagnosis of knee osteoarthritis is typically based on a combination of medical history, physical examination, and imaging studies such as X-rays, MRI (magnetic resonance imaging), or CT (computed tomography) scans to assess the severity of joint damage and rule out other possible causes of knee pain.
Treatment for knee osteoarthritis may include a combination of non-pharmacological interventions such as exercise therapy, weight management, physical therapy, joint protection techniques, assistive devices, and lifestyle modifications, as well as pharmacological treatments such as pain medications, anti-inflammatory drugs, and corticosteroid injections. In severe cases, surgical interventions such as arthroscopic surgery, partial knee replacement, or total knee replacement may be considered.
