Obesity-related knee osteoarthritis: a role for the rheumatology advanced nurse practitioner in Ireland.

Arthritis is the leading cause of disability in Ireland with knee osteoarthritis the most common presentation. One in five women and one in 10 men over the age of 60 in Ireland are diagnosed with osteoarthritis. The causative factors are multifactorial, but the increasing incidence of obesity is contributing greatly to the occurrence of osteoarthritis of the weight-bearing joints. The rheumatology advanced nurse practitioner is an autonomous clinical practitioner and potential solution to the growing numbers of people needing interventions for osteoarthritis, due to their ability to assess, diagnose, treat, and discharge these patients who ordinarily would be assessed from a medical waiting list. As obesity is becoming increasingly prevalent, it is important to address this with the patient cohort to try to reduce the burden of disease and treat not only the symptomatic knee osteoarthritis but the causative factors and provide patient-centred care.
