Study Notes
Osteoarthritis: Risk Factors, Clinical Manifestations, Assessment, and Management
- Osteoarthritis (OA) risk factors include aging, obesity, joint overuse, previous injuries, muscle weakness, genetic predisposition, and certain diseases.
- Obesity is the most prominent modifiable risk factor for OA, reducing both quality and quantity of life when combined with OA.
- Clinical manifestations of OA include joint pain aggravated by movement, brief morning stiffness, insidious onset, and physical signs such as joint enlargement and decreased range of motion.
- Blood tests and joint fluid examination are not useful for diagnosing OA, but X-rays may show narrowing of joint space, osteophyte formation, and thickened subchondral bone.
- Management goals for OA are to decrease pain and stiffness and maintain or improve joint mobility.
- Exercise, particularly cardiovascular aerobic exercise and lower extremity strength training, can prevent OA progression and decrease symptoms.
- Weight loss is beneficial for OA as it decreases excess load on the joint.
- Occupational and physical therapy can help patients adopt self-management strategies for OA.
- Wedged insoles, knee braces, orthotic devices, and walking aids are being evaluated as potential OA therapies to treat biomechanical abnormalities.
- Complementary, alternative, and integrative health therapies such as massage, yoga, and acupuncture are used by OA patients, and research is ongoing to determine their effectiveness.
- Nursing management of OA focuses on pain management, functional ability, education, and understanding of disease process and symptoms.
- Surgical interventions such as osteotomy and arthroplasty may be used in moderate to severe OA with severe pain or loss of function.
