Abstract
PURPOSE: Knee arthroscopy, with its unique advantages, has become a routine surgery and is widely carried out around the world. Venous thromboembolism (VTE) after knee arthroscopy is a potentially serious complication. This article analyzes the effects of anticoagulant therapy after knee arthroscopy. METHODS: We used key words or entry terms without any limitations to search the PubMed, Embase, and Cochrane Library databases. Randomized controlled trials (RCTs) of drug prophylaxis for VTE after knee arthroscopy until November 2017 were included in our review. RESULTS: This systematic review identified nine RCTs, consisting of 4290 patients, investigating drug prophylaxis in knee arthroscopy. There are three main drugs for preventing thrombosis after arthroscopic knee surgery: low-molecular-weight heparin (LMWH), rivaroxaban, and aspirin. Our study concluded that there is no difference in symptomatic VTE (excluding symptomatic distal DVT) risk during anticoagulant prophylaxis (RR, 0.98; 95% CI, 0.44-2.19; I2 value = 0%; P = 0.97). Moreover, there was a lower incidence of symptomatic distal DVT (RR, 0.16; 95% CI, 0.06-0.45; I2 value = 0%; P = 0.0005) in the anticoagulant group than in the control group. CONCLUSIONS: In our study, anticoagulant therapy after knee arthroscopy was ineffective. We recommend that anticoagulants not be provided routinely after knee arthroscopy.
