The type of pneumonia (coronavirus disease 2019, COVID-19) that is caused by the new coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2) is now spreading across the world in a pandemic. Many patients with COVID-19 were admitted to the University Hospital Aachen during an outbreak that first struck the Heinsberg district in February 2020. ⋯ This initial description of a cohort of COVID-19 patients with and without ARDS in Germany reveals that those with ARDS more commonly have preexisting respiratory diseases and obesity, as well as persistently elevated inflammatory markers. COVID-19 patients without ARDS may likewise require prolonged hospitalization because of persistently elevated inflammatory values with a simultaneous need for supplemental oxygen.

Primary patellar dislocation is often the initial manifestation of patellofemoral instability. Its long-term consequences can include recurrent dislocation and permanent dysfunction of the knee joint. There is no consensus on the optimal treatment of primary patellar dislocation in the relevant literature. The main prerequisite for a good long-term result is a realistic assessment of the risk of recurrent dislocation. ⋯ The risk of recurrent dislocation after primary patellar dislocation is increased by a number of risk factors, and even more so when multiple such risk factors are present. Published stratification models enable an assessment of the individual risk profile. Patients at low risk can be managed conservatively; surgery should be considered for patients at high risk.
