Osteoarthritis of Knee

Osteoarthritis of the knee is a degenerative joint disease in which the protective cartilage cushioning the ends of the bones within the knee joint gradually wears down, leading to bone-on-bone friction, pain, and stiffness. It is the most common form of arthritis and typically develops slowly over years, worsening with age and repetitive joint stress. As cartilage loss progresses, the joint may develop bony spurs, inflammation, and reduced range of motion that increasingly limit mobility. It significantly impacts quality of life, particularly among older adults and those who are overweight.

The most common symptoms include: Knee pain that worsens with activity and improves with rest; joint stiffness especially in the morning or after sitting; swelling around the knee; a grating or crackling sensation with movement. Early recognition is key to prompt diagnosis and effective treatment.

No, Osteoarthritis of Knee is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

Treatment options include: Initial management includes weight loss; physical therapy to strengthen supporting muscles; and pain relief with acetaminophen or nonsteroidal anti-inflammatory drugs. Intra-articular injections of corticosteroids or hyaluronic acid can provide temporary relief for moderate cases. Treatment should always be guided by a qualified Orthopedics specialist. Do not self-medicate.

While Osteoarthritis of Knee cannot always be fully prevented, several measures can reduce risk: Maintaining a healthy body weight to reduce joint load; regular low-impact exercise to strengthen muscles around the knee; avoiding repetitive high-impact joint stress.

Consult a Orthopedics specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
