Key Concepts

Osteoarthritis

Osteoarthritis is a degenerative joint disease characterized by the progressive deterioration of cartilage in the joints, which leads to pain, swelling, and stiffness. It often results from long-term wear and tear on the joints, especially in weight-bearing areas such as the knees. This condition becomes more likely with age and repetitive stress, as the protective cartilage is gradually worn down, leading to inflammation and discomfort.

Repetitive Stress Injury

Repetitive stress injuries occur when repetitive motion or prolonged pressure on a joint or body part causes cumulative damage over time. In the context of occupational activities, such as cleaning that involves frequent kneeling, bending, and other physically demanding movements, continuous strain on the knee can contribute to joint degeneration. This kind of repetitive overuse is a common cause of osteoarthritis, as the constant mechanical stress accelerates the breakdown of joint tissues.
