Post covid-19 reactive arthritis: An emerging existence in the spectrum of musculoskeletal complications of SARSCoV-2 infection

Reactive arthritis is commonly preceded by a gastrointestinal or a sexually transmitted infection. However, its association with different viral infections has also been reported. Herein, we report a case of a 34 year old male who developed Reactive arthritis few days after the severe acute respiratory syndrome corona virus 2 infection (SARS-CoV-2). The patient was positive for COVID-19 infection from nasopharyngeal swab specimen. He was advised self-isolation/quarantine, considering his mild form of disease, along with medication. Ten days later he developed severe pain and tenderness in his right knee joint. His MRI of the affected joint revealed mild effusion (secondary to inflammation) in the patella-femoral compartment. Patient was diagnosed with Reactive arthritis and was prescribed Non-Steroidal Anti-Inflammatory Drugs (NSAIDs). Intra articular glucocorticoid was injected, to which he responded dramatically. His symptoms completely resolved in next ten days.
