Knee Pain can arise from 2 documented medical conditions. Understanding the clinical context helps identify urgent causes early.
Osteoarthritis
Osteoarthritis is the most common form of arthritis, caused by the gradual breakdown of cartilage in joints. It primarily affects the knees, hips, hands, and spine, causing pain, stiffness, and reduced range of motion.
Meniscus Tear
A meniscus tear is damage to the fibrocartilage of the knee, causing pain, swelling, stiffness, and clicking or locking. It commonly occurs during twisting injuries; treatment depends on tear type (conservative vs. surgical repair).
