Study Notes

Osteoarthritis: Clinical Manifestations, Assessment, and Management

Osteoarthritis (OA) is a degenerative joint disease with risk factors including aging, obesity, joint overuse, and previous injuries.
Obesity is a significant modifiable risk factor for OA, impacting both quality and quantity of life.
Clinical manifestations of OA include joint pain worsened by movement, morning stiffness lasting less than 30 minutes, and bony enlargements in affected joints.
Blood tests and joint fluid examination are not useful for diagnosing OA, but X-rays may show joint space narrowing and osteophyte formation.
Management goals for OA involve pain and stiffness reduction, joint mobility maintenance, and improvement through exercise, weight loss, and therapy.
Exercise, particularly cardiovascular aerobic exercise and strength training, can prevent OA progression and alleviate symptoms.
Complementary, alternative, and integrative health therapies like massage, yoga, and acupuncture are used by OA patients, but their effectiveness is still being studied.
Nursing interventions for OA focus on pain management, functional ability optimization, and patient education.
Surgical interventions, such as osteotomy and arthroplasty, are considered in moderate to severe OA cases with severe pain or loss of function.
Joint arthroplasty involves surgically replacing unhealthy joints with metal or synthetic materials, commonly used in severe OA cases as well as in conditions like rheumatoid arthritis and trauma.
Exercise should be planned when pain is least severe, and open discussions about the use of complementary therapies are important for safe and effective practices.
Osteoarthritis can be managed through a combination of nonpharmacologic approaches, education, and possibly surgical intervention in severe cases.
