Overview

Patellar Tendinitis

Patellar tendinitis is inflammation of the tendon connecting the kneecap to the shinbone.

Osteoarthritis

Osteoarthritis is the most common form of arthritis and is a degenerative joint disease that occurs when the protective cartilage cushioning the ends of bones gradually wears down. It commonly affects the knees, hips, hands, feet, and spine. Symptoms usually develop slowly over time and may include pain, stiffness, reduced flexibility, and difficulty performing daily activities. Although osteoarthritis cannot be completely reversed, proper treatment and lifestyle modifications can significantly improve quality of life.
