Study Notes
Osteoarthritis: Risk Factors, Clinical Manifestations, and Management
- Osteoarthritis (OA) risk factors include age, gender, occupation, sport activities, previous injuries, muscle weakness, genetic predisposition, and certain diseases.
- Obesity is the most prominent modifiable risk factor for OA, impacting both quality and quantity of life.
- Clinical manifestations of OA include joint pain, stiffness, functional impairment, and bony enlargements in affected joints.
- Blood tests and joint fluid examination are not useful for OA diagnosis; X-rays may show narrowing of joint space and osteophyte formation.
- Management goals for OA are to decrease pain and stiffness, maintain or improve joint mobility, and prevent OA progression.
- Exercise, especially cardiovascular aerobic exercise and strength training, can prevent OA progression and decrease symptoms.
- Weight loss can be beneficial by decreasing excess load on the joint.
- Occupational and physical therapy can help patients adopt self-management strategies, and orthotic devices such as knee braces and insoles are being evaluated as possible therapies.
- Complementary, alternative, and integrative health therapies like massage, yoga, and acupuncture are used by patients, but their effectiveness is still being studied.
- Nursing interventions for OA focus on pain management, optimal functional ability, and patient education.
- Surgical interventions such as osteotomy and joint arthroplasty may be considered in moderate to severe OA with severe pain or loss of function.
- Joint arthroplasty involves the surgical removal of an unhealthy joint and replacement with metal or synthetic materials, and may be used for severe joint pain and disability in OA, RA, trauma, and congenital deformity.
