Abstract:

BACKGROUND: Drainage placement and pattern during total knee arthroplasty (TKA) remain controversial.
OBJECTIVE: To explore the effect of subcutaneous drainage after unilateral TKA with or without drainage.
METHODS: A randomized prospective study was performed. The 101 patients were divided into 3 groups: subcutaneous drainage (n=35), articular cavity drainage (n=32), no drainage (n=34). The blood loss, blood transfusion and hemoglobin reduction among groups were compared. The recovery after surgery and the correlative complications were analyzed.
RESULTS AND CONCLUSION: Subcutaneous ecchymosis area (11-30 cm2, > 30 cm2) and knee joint diameter increase rate 3 days post surgery were significantly lower in subcutaneous drainage group compared with other groups (P < 0.05); blood transfusion amount, drainage amount 24 hours post replacement, hemoglobin reduction were lower in subcutaneous drainage group compared with articular cavity drainage group (P < 0.05). The pain scores, flexion degree, infection rate during 1-year follow-up were similar among the groups (P > 0.05). Results show that subcutaneous drainage has advantages after unilateral TKA compared with articular cavity drainage or no drainage.
