“…However, this modality has the disadvantage of increasing blood loss [7,18,22,29,30,44]. In contrast, some surgeons favor not placing an indwelling vacuum drain to avoid increased blood loss [1,3,10,15,20,23,28,30,35,36], although this strategy increases the risk of wound problems and the need for more frequent dressing reinforcement [18,22,29,30]. We hypothesized that subcutaneous closed-suction drainage would be a potentially efficacious alternative to either intraarticular closedsuction drainage or no drain because it could exploit the advantages of both methods, namely, the drainage and the joint tamponade effects.…”
