Osteoarthritis - the truth

Osteoarthritis is presented as a very common cause of knee pain, especially in people over 50, and its prevalence has risen markedly over time. The main focus is not only on what osteoarthritis is, but also on how clinicians should explain it. Learners are encouraged to avoid fear-based language, since alarming descriptions of degeneration or imaging findings can increase catastrophizing and inactivity. A central message is that osteoarthritis is not simply “wear and tear.” Physical activity supports joint health, may slow degeneration, and does not inherently damage the knees. Running, including higher volumes, is described as generally safe and sometimes protective, even for people with osteoarthritis. Imaging is also placed in perspective: MRI is rarely needed for knee osteoarthritis, and X-rays or MRI findings often do not explain pain well. Key risk factors and diagnostic criteria are outlined, including age, sex, BMI, previous injury, alignment, heavy occupational load, and reduced quadriceps strength. Management emphasizes exercise therapy, especially strengthening the quadriceps and glutes, cardiovascular training, gradual progression, and weight reduction. Surgery is described as unnecessary for most patients, with rehabilitation often providing comparable benefits.
