Hip osteoarthritis: patients with complex comorbidities can make exceptional improvements following intensive exercise and education.

A 71-year-old man presenting with hip osteoarthritis, with a complex range of comorbidities was referred by his general practitioner to CHAIN (Cycling against Hip PAIN), a 6 week programme developed to aid self-management of hip osteoarthritis through exercise, education and advice, as defined by the National Institute for Health and Care Excellence (NICE) guidelines. Significant improvements were seen in Oxford hip score, the Hip disability and Osteoarthritis Outcome Score (HOOS) - function score, sit-to-stand test, timed up and go test, pain scores and hip flexion. There was also a weight loss of 2.1 kg. The man reported 'an amazing difference' in his affected hip and leg, and improved fitness. Many clinicians would have questioned the man's suitability for the programme due to his coexisting medical conditions. This case study shows that patients may be much more able than we think to achieve significant improvement with exercise.
