Q

What happens pathologically during the onset of osteoarthritis?

A

The collagen matrix becomes more disorganised, and there is a decrease in proteoglycan content within cartilage

Q

What is the result of the decrease in proteoglycan contact in early osteoarthritis?

A

Without the protective effect of proteoglycans, the fibers of the cartilage become susceptible to degradation, and thus exacerbate the degeneration

Q

What are the risk factors for the development of osteoarthritis?

A
  • Joint injury, or overusing the joint when it hasn’t had enough time to heal after injury or operation
  • Joints that are severely damaged by previous or existing conditions, such as rheumatoid arthritis or gout

Q

What mood factors should be assessed in the holistic management of osteoarthritis?

A

Screen for depression, and check for other current stresses in life

20
Q

What should be assessed regarding the support network in the holistic management of osteoarthritis?

A

Nede to know the ideas, concerns, and expectations of the main carer, and how the carer is coping. Also need to know if the patient is isolated, and how to manage this if so

21
Q

What should be assessed regarding other musculoskeletal pain in the holistic management of osteoarthritis?

A

Should find out if present, as this might suggest a chronic pain syndrome or another treatable source of pain

22
Q

What should be assessed regarding the influence of co-morbidity in the holistic management of osteoarthritis?

A

The patient may have an interaction between two or more co-morbidities. This might affect the fitness for surgery, or ability to understand surgical options. It might also alter the assessment of the most appropriate drug therapy, or increase the risk of falls

23
Q

What education should a patient with osteoarthritis be given?

A

About the condition and it’s management.

Should dispel common misconceptions, such as that the disease inevitably progresses and cannot be treated/

24
Q

What might be included in an individualised self-management plan for patients with osteoarthritis?

A
  • Positive behaviour changes
  • Weight loss
  • Use of suitable footwear
25
Q

In whom is exercise a core treatment in osteoarthritis?

A

Everyone, irrespective of age, comorbidity, pain severity, or disability

26
Q

What should exercise include in the management of osteoarthritis?

A

Local muscle stregthening and general aerobic fitness

27
Q

Who should be offered interventions to achieve weight loss in osteoarthritis?

A

Those who are obese or overweight

28
Q

What aids and devices can be used in the management of osteoarthritis?

A
  • Appropriate footwear
  • Bracing/joint supports
  • Assistive devices such as walking sticks and tap turners
29
Q

What is the role of transcutaneous electrical nerve stimulation (TENS) in osteoarthritis?

A

It should be considered as an adjunt to core treatments in pain relief

30
Q

What is the first line analgesia in osteoarthritis?

A

Paracetamol and topical NSAIDs

31
Q

What is used if paracetamol and topical NSAIDs are ineffective in the treatment of osteoarthritis?

A

Consider opioid analgesics, taking into account risks and benefits, particularly in the elderly

Oral NSAIDs or COX-2 inhibitors can be considered

32
Q

What should be done when giving oral NSAIDs or COX-2 inhibitors in osteoarthritis?

A

You should give at lowest possible dose, for shortest period of time.

You should co-prescribe a PPI

33
Q

What is the role of intra-articular corticosteroid injections in the treatment of osteoarthritis?

A

They can be considered as an adjunct to other analgesia in the relief of moderate to severe pain with osteoarthritis

34
Q

When might surgery be considered in osteoarthritis?

A

In people who are experiencing joint symptoms, including pain, stiffness, and reduced function, that has a substantial impact on their quality of life, and are not responding to non-surgical treatment

35
Q

What factors should not be a barrier to referral for joint surgery

A

Patient specific factors, such as;

  • Age
  • Sex
  • Smoking
  • Obesity
  • Co-morbidities
36
Q

What should be discussed when considering the possibility of joint surgery in osteoarthritis?

A
  • Benefits and risks of surgery
  • Consequences of not having surgery
  • Recovery and rehabilitation after surgery
  • How having a prosthesis may affect them
37
Q

What are the surgical options in osteoarthritis?

A
  • Arthroplasty
  • Artherodesis
  • Osteotomy
38
Q

What is arthroplasty?

A

Joint replacement therapy

39
Q

What joints is arthroplasty most commonly carried out on?

A

The hip and knee joints

40
Q

What happens during an arthroplasty?

A

The affected joint is removed and replaced with a prosthesis made out of plastic and metal

41
Q

How long can a joint replacement last for?

A

Up to 20 years

42
Q

What is arthrodesis?

A

Where the joint is fused together in a pernament position, making the joint stronger and much less painful, but no longer mobile

43
Q

When is arthrodesis used?

A

When joint replacement isn’t suitable

44
Q

What does an osteotomy involve?

A

Adding a small section of bone either above or below the knee joint

45
Q

What is the purpose of an osteotomy?

A

It helps realign the knee, so that the body weight is no longer focused on the damaged part of the knee, providing symptomatic relief

46
Q

When is an osteotomy used in the management of osteoarthritis?

A

When the patient has osteoarthritis in the knees, but isn’t suitable for a knee replacement
