Low-value care is receiving substantial attention in many fields of medicine but little-to-none in sports medicine. Common interventions for sport and exercise-related injuries include medical imaging, medication, surgery and rehabilitation, but there is emerging evidence of the inappropriate use of these interventions. This chapter aims to increase awareness of low-value care in sports medicine by answering four key clinical questions: Does my patient need imaging? When is it appropriate to prescribe opioids? Does my patient need surgery? Does it matter how rehabilitation is delivered? Increasing awareness of low-value care in sports medicine will ensure patients with sport or exercise-related injuries avoid care that provides little-to-no benefit or causes harm and receive care that is evidence based and truly necessary. There are many situations when imaging, opioids, surgery and supervised rehabilitation are entirely appropriate. However, this chapter considers contexts where use of these interventions could be considered unnecessary and potentially harmful.
