Abstract
Coronavirus disease 19 (COVID-19) is the worst pandemic ever recorded in history, as of this day more than 545 million people infected and more than 6 million cumulative deaths. COVID 19 is primarily respiratory disease, however non-respiratory presentations that could be manifested are venous and arterial thromboembolic events. Both pulmonary embolism (PE) and deep vein thrombosis (DVT) are the most frequently thrombotic events in COVID-19.
Knee arthroscopy surgery is the one of the most common orthopedic surgical procedures nowadays, with the most common procedures are meniscectomy, meniscal repair and cruciate ligament reconstruction. Although knee arthroscopy is known to be a safe procedure, several complications could be found with the 3 most common complications are DVT, effusion and synovitis, and PE.
We reported a case series of four patients with DVT post knee arthroscopy anterior cruciate ligament reconstruction during 2021. The DVT diagnosis was retained on clinical presentation and elevated of D-dimer testing.
The patient’s mean age was 35,25 years, and all of the patients had no risk factors of DVT, although they had COVID-19 infection within 3 months before surgery. The most common clinical presentation was swelling on the lower leg (around the ankle) with slightly pain and numbness. Only one patient had severe pain around the thigh. All of the patients had elevated D-dimer testing result with mean of D-dimer 1250 (normal value < 500). Only one patient had sonography testing and found proximal DVT. One of the patients had DVT at post operative day (POD) 3, one at POD 4 and the other two at POD 5. Three of the patients improved with oral anticoagulant therapy using rivaroxaban (XARELTO). In one patient the symptom was not improved after two days oral anticoagulant therapy and underwent thrombectomy by vascular surgeon.
DVT is the most common complication of knee arthroscopy and also the most common non-respiratory events of COVID-19 infection. Routinely administration of thromboprophylaxis agent was not recommended, pre-operative risk assessment of DVT should be used, especially in post-COVID 19 patients.
