Treatment of the relapsing dislocation of the patella (author's transl)

From 1970-1977, twenty-five patients were given surgical treatment for relapsing dislocation of the patella. The mean age of the patients was 22 years. The case material consisted of 18 female and 7 male patients. The average frequency rate of dislocation was three to fifteen times. (Reported from the BB-Accident Hospital Tübingen). The combined surgical method with gracilis muscle restraint described by Krogius, was used in this clinic in view of its traditionally successful application. Additional antepositioning of the patella according to Bandi was effected in intraoperatively discovered retropatellar arthrosis. Relapses of dislocation were reported in two cases. Good postoperative results were obtained in 14 patients, satisfactory results in 5 patients, and an unsatisfactory outcome in three patients. Redislocation was reported twice. Since this disease occurs preferably in juveniles, surgical treatment to prevent further dislocations should be effected well in time to avoid early retropatellar arthrosis. Since dislocations of the patella are frequently adjusted spontaneously without any treatment, critical and detailed anamnesis is imperative in every patient with a distorted knee joint.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
