What is 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.

Very common — affects a large proportion of adults over 60, with prevalence rising steadily with age
No
Causes of Osteoarthritis of Knee
Results from the gradual mechanical wear of cartilage combined with low-grade joint inflammation, often accelerated by obesity, previous knee injury, repetitive stress from occupation or sports, and misalignment of the joint. Age is the strongest risk factor, as cartilage naturally loses its resilience over time, while genetics also influences susceptibility. Muscle weakness around the joint further increases mechanical stress on the cartilage.
Symptoms of Osteoarthritis of Knee
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, reduced range of motion, joint instability or buckling, visible joint deformity in advanced cases
Treatment & Types of Osteoarthritis of Knee in Karnataka
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, while assistive devices like knee braces help with mobility. Advanced or refractory disease is treated with surgical options ranging from arthroscopic debridement to partial or total knee replacement.
Knee osteoarthritis is graded using imaging-based systems from grade 1, minimal with possible early joint space narrowing, through grade 4, severe with significant cartilage loss, bone spurs, and joint deformity, which helps guide whether conservative management or surgical options like joint replacement are more appropriate.

Frequently Asked Questions
What grade of knee osteoarthritis needs surgery?
Advanced grades, particularly grade 4 with significant cartilage loss and deformity, are more likely to eventually need joint replacement, while earlier grades are usually managed well with weight loss, physical therapy, and medication.
Can knee osteoarthritis be prevented after a sports injury?
Treating knee injuries promptly and completely, along with strengthening the muscles around the joint, can reduce but not eliminate the increased risk of developing osteoarthritis after a significant knee injury.
How effective are hyaluronic acid or corticosteroid injections for knee osteoarthritis?
Both can provide meaningful temporary relief for moderate cases, though effects vary between individuals and typically last weeks to a few months rather than being a permanent solution.
Is walking bad for knee osteoarthritis?
No, regular low-impact activity like walking is generally beneficial and helps maintain joint function and strengthen supporting muscles, though very high-impact activities may need to be modified.
What does a total knee replacement actually involve?
It's a surgical procedure that replaces the damaged joint surfaces with artificial components, typically reserved for advanced, disabling osteoarthritis that hasn't responded to other treatments, and can significantly restore mobility and reduce pain.
