Osteoarthritis (Degenerative Joint Disease)

A nurse is assessing a 65-year-old client with osteoarthritis of the knees. Which assessment finding would be most characteristic of this condition?

1 Sharp, stabbing pain that occurs primarily at rest
2 Symmetrical joint swelling with morning stiffness lasting over 2 hours
3 Joint pain that worsens with activity and improves with rest ✓ 정답
4 Fever and systemic symptoms accompanying joint pain

해설

Joint pain worsening with activity and improving with rest is the hallmark of osteoarthritis, due to mechanical cartilage wear, distinguishing it from inflammatory arthritis.

Understanding the Clinical Presentation of Knee Osteoarthritis

The most characteristic assessment finding for a client with knee osteoarthritis (OA) is joint pain that worsens with activity and improves with rest. This pattern is a hallmark of the mechanical pathophysiology underlying OA. In this degenerative joint disease, the protective articular cartilage that cushions the ends of bones wears down over time. As a result, during weight-bearing activities such as walking or climbing stairs, the increased mechanical stress and friction on the subchondral bone lead to pain. When the joint is at rest, this mechanical stress is removed, providing relief. This is clinically described as a "mechanical" pain pattern, which is distinct from the "inflammatory" pain pattern seen in conditions like rheumatoid arthritis.

To further clarify this distinction for the NCLEX-RN, consider the other options. Sharp, stabbing pain at rest is not typical for OA and may suggest an acute injury, such as a meniscal tear, or a neuropathic component. Symmetrical joint swelling with prolonged morning stiffness lasting over an hour is a classic feature of rheumatoid arthritis, a systemic autoimmune condition, rather than the asymmetrical, localized degeneration of OA. Similarly, fever and systemic symptoms are red flags for an infectious or inflammatory arthritis, such as septic arthritis, and are not associated with the localized, non-inflammatory nature of OA.

The global burden of this condition is immense, with knee OA constituting 83% of the overall OA disease burden ^[2]. This high prevalence makes it a critical topic for nursing assessment. Your physical examination should focus on identifying findings consistent with this mechanical wear-and-tear process, including crepitus (a grating sensation or sound during joint movement), bony enlargement, and pain localized to the medial or lateral joint line that is reliably reproduced with active or passive range of motion. The Kellgren-Lawrence classification system is often used to grade the radiographic severity of these changes, from doubtful joint space narrowing to large osteophyte formation and severe sclerosis ^[2]. Recognizing the activity-dependent nature of the pain is the cornerstone of differentiating OA from other joint disorders and guiding appropriate nursing interventions, such as balancing rest with prescribed exercise and weight management strategies.
