What is the purpose of the Total Joint Arthroplasty (TJA)?
Involves the replacement of all components of an articulating joint
Which components are most commonly used in joint replacements?
Metal (e.g., stainless steel, cobalt-chromium, titanium) and high-density polyethylene components
What is the function of the synovial fluid in the joint?
To lubricate and protect the joint's movement
What is the result of the breakdown of articular cartilage in osteoarthritis?
Formation of osteophytes that protrude into the joint space
What are the risk factors for osteoarthritis and its progression?
Older age, female gender, and obesity
What happens to the joint space in osteoarthritis?
It is narrowed, leading to decreased joint movement
What is the role of articular cartilage in the joint?
To protect the bone from damage with physical activity
How does osteoarthritis pathophysiology differ from the previous understanding?
It has been greatly expanded beyond the concept of 'wear and tear' related to aging
What is the eventual outcome of progressive damage to the underlying bone in osteoarthritis?
Formation of osteophytes (bone spurs)
What is the primary component of the joint that is affected in osteoarthritis?
Articular cartilage
What role does the subchondral bone play in a joint?
It is the bone to which the articular cartilage is attached
What is the function of the joint space in a joint affected by osteoarthritis?
It allows for movement and becomes narrowed in osteoarthritis
Which of the following is the most prominent modifiable risk factor for osteoarthritis?
Obesity
What are the clinical manifestations of osteoarthritis?
Joint pain, stiffness, and bony enlargements
What is the primary goal of management for osteoarthritis?
Decreasing pain and stiffness
Which type of exercise can prevent osteoarthritis progression and decrease symptoms?
Cardiovascular aerobic exercise and strength training
What is the potential benefit of weight loss for osteoarthritis patients?
Decrease excess load on the joint
What is the focus of nursing interventions for osteoarthritis?
Pain management, optimal functional ability, and patient education
In which cases may surgical interventions such as osteotomy and joint arthroplasty be considered for osteoarthritis?
Moderate to severe OA with severe pain or loss of function
What does joint arthroplasty involve?
Surgical removal of an unhealthy joint and replacement with metal or synthetic materials
Which of the following therapies are being evaluated as possible treatments for osteoarthritis?
Complementary, alternative, and integrative health therapies like massage, yoga, and acupuncture
What is the most prominent non-modifiable risk factor for osteoarthritis?
Age
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.
