背景：关节置换后放置引流已经作为一种常规应用于髋、膝关节置换后，然而，引流管作为外界与关节相通的潜在通道，可能成为细菌等病原体入侵关节腔的门户。 　　目的：评价引流管在人工膝关节置换术中的临床意义及安全性。 　　方法：对80例需行人工膝关节置换的患者按照住院号的单双号随机分为引流组(38例)与非引流组(42例)，根据公式计算并对关节置换后失血量、需输血人数及输血量、置换后并发症及膝关节功能的恢复情况进行统计分析。 　　结果与结论：出院后继续随访2年，其中非引流组2例失访，78例患者纳入结果分析。关节置换后总失血量、需输血人数、输血量，引流组多于非引流组；置换后第3天膝关节主动活动度，引流组要大于非引流组；置换后血红蛋白变化值及末次随访两组患者KSS评分差异无显著性意义。结果表明人工膝关节置换后放置引流将增加后的失血及输血，但在置换后早期膝关节功能的恢复方面可能存在积极的意义，远期膝关节功能评分及置换后并发症两组差异无显著性意义。

BACKGROUND:Drainage has been applied as a routine to hip and knee replacement surgery. However, as a potential channel, drainage could become a portal for bacteria and other pathogens to invade the joint cavity. OBJECTIVE:To evaluate the clinical significance and safety of drainage in total knee arthroplasty. METHODS:The 80 patients were prospectively randomized into two groups:Group 1 included 38 patients with wound drainage;Group 2 included 42 patients without any drainage. According to a formula calculation, blood loss, the number of subjects requiring blood transfusion, volume of blood transfusion, complications and the recovery of function after total knee arthroplasty were statistical y analyzed. RESULTS AND CONCLUSION:The subjects were fol owed up for 2 years after discharge. Two patients lost to fol ow up in the non-drainage group. 78 patients were involved in the result analysis. The total blood loss, the number of subjects requiring blood transfusion and volume of blood transfusion were more in the drainage group than those in the non-drainage group after surgery. At 3 days after arthroplasty, active range of motion was larger in the drainage group than that in the non-drainage group. No significant differences in hemoglobin levels and Keen Society Score scores were detected after arthroplasty between the two groups. Results suggested that draining wil increase the blood loss and blood transfusion, but it may contribute to the early recovery of knee function. No significant differences in long-period Keen Society Score scores and postoperative complications were detectable between the two groups.
