Patient Background: Sarah, a 60-year-old retiree, presents to the orthopedic clinic with complaints of chronic knee pain that has persisted for several years. She describes the pain as an internal throbbing sensation deep within both knees, exacerbated by weight-bearing activities such as walking and standing for prolonged periods. Sarah reports stiffness and swelling in her knees, limiting her mobility and impacting her ability to perform daily activities. Additionally, she expresses feelings of frustration, anxiety, and helplessness due to the ongoing nature of her pain. Clinical Assessment: Upon examination, Sarah demonstrates decreased range of motion in both knees and tenderness upon palpation of the knee joints. X-rays reveal evidence of osteoarthritis, with joint space narrowing, osteophyte formation, and subchondral sclerosis consistent with degenerative changes.
