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.
