Abstract
Background TKA can involve substantial bleeding, and the issue regarding whether vacuum drainage should be used during TKA continues to be debated as both methods have disadvantages. Questions/purposes We therefore asked whether subcutaneous indwelling vacuum drainage is advantageous over intraarticular indwelling vacuum drainage in terms of blood drainage, bleeding-related complications, and functional outcomes in primary TKA. Patients and methods We randomized 111 patients undergoing TKAs to have either a subcutaneous indwelling or an intraarticular indwelling catheter and compared the two groups for blood loss (hemoglobin decrease, transfusion requirements, hypotension episode), incidence of wound problems (requirements for dressing reinforcement, oozing, hematoma, hemarthrosis, ecchymosis, infection), and functional outcomes (recovery of motion arc, American Knee Society, WOMAC, and SF-36 scores) at 12 months after surgery. Results The mean vacuum drainage volume was less in the subcutaneous indwelling group than in the intraarticular indwelling group (140 mL versus 352 mL). The groups were similar in terms of decreases in hemoglobin after 2 and 5 days (3.0 versus 3.3 g/dL and 3.3 versus 3.7 g/dL, respectively), allogenic transfusion requirements (4% versus 11%), incidence of wound problems, and functional scores. Conclusions The data suggest subcutaneous indwelling closed-suction drainage is a reasonable alternative to intraarticular indwelling closed-suction drainage and to no suction drainage.
