This article is centred around the similarities and highlights some differences between a sports injury compared with any other injury profile. The authors use a musculoskeletal assessment, diagnosis and management of an injury based on a particular case study. The intention is to highlight how problems may be masqueraded in the history and perception of the injured athlete and how this perception may have complicated the injury and the rehabilitation process. This issue generates a renewed awareness for all primary care nurses and health practitioners who may be involved in treatment pathways for associated injuries related to sports medicine problems. The article gives an insight into peroneal dislocation/subluxation, but primarily focuses on peroneal tendonitis/tendonosis. The management of the injury briefly touches on the associated benefits (and risks) of barefoot running and its role in the prevention of sporting injuries. This article illustrates how the frustration of a chronic injury can lead to the athlete making ill-informed decisions and highlights the need for a thorough assessment and an evidence-based management plan that is negotiated with the athlete.
