Abstract
BACKGROUND: COVID-19 is an emergent infection, the long-term complications of which are still under study. While hypercoagulability is a common feature in severe cases, the incidence of ischemic complications such as osteonecrosis remains unknown. Previous studies on SARS-CoV1 found an increase in osteonecrosis 3-36 months after infection, and it is still unclear if this was related to the use of corticosteroids or to the virus itself. METHODS: We introduce a 78-year-old woman who complained of right knee pain and swelling a month after COVID-19 infection onset. Her knee radiography showed no significant changes compared to previous ones. MRI, on the other hand, found osteonecrosis in the internal femoral condyle. No coagulation abnormalities were found in blood tests. RESULTS: While knee replacement should be her main treatment, it will be long delayed due to the pandemic. In the meantime, we increased her tapentadol and salicylic acid doses and gave her home exercises to improve functionality. CONCLUSION: In the follow-up after COVID-19, any muscular or joint pain with unusual characteristics should be carefully examined.
