Knee Osteoarthritis (Degenerative Knee)

Knee osteoarthritis (gonarthrosis/degenerative knee) is progressive degenerative joint disease with cartilage loss/osteophytes/subchondral sclerosis, causing pain/stiffness/crepitus/limited motion. Treatment: patient education; weight loss; low-impact exercise (walking/cycling/swimming); physical therapy (quadriceps strengthening); acetaminophen; NSAIDs (oral/topical); intra-articular corticosteroid injections; hyaluronic acid injections; capsaicin/topical NSAIDs; orthotics/bracing; cane; surgical arthroscopy/osteotomy/total knee arthroplasty for advanced; avoid high-impact; follow-up orthopedics/rheumatology/PT.

Common Symptoms

Knee pain; stiffness; crepitus; limited motion; deformity; morning stiffness <30 min

Causes and Pathogenesis

Cartilage degeneration + osteophyte + subchondral bone remodeling causes knee osteoarthritis.

Treatment

Acetaminophen/NSAIDs; intra-articular steroids/HA; PT/weight loss; arthroplasty

Preventive Measures

Weight control; low-impact exercise; avoid trauma; strong quadriceps.

Department to Visit
