The Balance Error Scoring System (BESS) is a useful means of measuring postural stability, which frequently exhibits deficits after a concussion. However, it has limited applicability for children since there is insufficient normative data available for the BESS in the pediatric population. The purposes of this study were to report scores for the BESS in children 10 to 17 years old with no history of concussion and to identify whether BESS score is correlated with age, sex, sports participation, height, weight, or body mass index. ⋯ These results provide a reference for clinicians using BESS to evaluate and manage children and teens with concussions.

Popliteal synovial cysts, also known as Baker's cysts, are commonly found in association with intra-articular knee disorders, such as osteoarthritis and meniscus tears. Histologically, the cyst walls resemble synovial tissue with fibrosis evident, and there may be chronic nonspecific inflammation present. Osteocartilaginous loose bodies may also be found within the cyst, even if they are not seen in the knee joint. Baker's cysts can be a source of posterior knee pain that persists despite surgical treatment of the intra-articular lesion, and they are routinely discovered on magnetic resonance imaging scans of the symptomatic knee. Symptoms related to a popliteal cyst origin are infrequent and may be related to size. ⋯ A capsular opening to the semimembranosus-medial head gastrocnemius bursa is a commonly found normal anatomic variant. It is thought that this can lead to the formation of a popliteal cyst in the presence of chronic knee effusions as a result of intra-articular pathology. Management of symptomatic popliteal cysts is conservative. The intra-articular pathology should be first addressed by arthroscopy. If surgical excision later becomes necessary, a limited posteromedial approach is often employed. Other treatments, such as arthroscopic debridement and closure of the valvular mechanism, are not well studied and cannot yet be recommended.
