For both femoroacetabular impingement (FAI) and core muscles injuries, a thorough history and physical examination are paramount to guide the treatment. While advanced imaging including computed tomography and magnetic resonance imaging are frequently obtained, a wealth of information can be ascertained from standard radiographs alone. For patients with isolated or combined FAI and core muscle injuries (CMIs), the initial treatment is often nonoperative and consists of rest, activity modification, and physical therapy of the hips, core, and trunk. Injections may then aid in both confirming diagnosis and temporary symptom abatement. Arthroscopic procedures for refractory FAI in experienced hands have been shown to be both safe and efficacious. While surgical repair options for CMIs are significantly more variable, long-term studies have demonstrated the rapid resolution of symptoms and high return to play rates. More recently, anatomic and clinical correlations between FAI and CMIs have been identified. Special attention must be paid to elite athletes as the incidence of concurrent FAI with CMI is extremely high yet with significant symptom variability. Predictable return to play in athletes with coexisting symptomatic intra-articular and extra-articular symptomatology is incumbent upon the treatment of both pathologies.
