Did you know that knee arthritis affects over 10 million adults in the United States, primarily due to wear-and-tear on the joint's cartilage over time? This degenerative condition, known as osteoarthritis, impairs the smooth movement between bones and can lead to pain, stiffness, and reduced mobility. While aging is a key factor, research shows that biomechanical imbalances, previous injuries, and lifestyle also play significant roles in its progression. Understanding the structural changes within the knee joint highlights the importance of early intervention strategies, including physical therapy, to support joint function and improve daily comfort.
