Background

Anterior cruciate ligament reconstruction (ACLR) is reportedly associated with a higher incidence of deep vein thrombosis (DVT) incidence than other arthroscopic surgical procedures. The aim of this study is to retrospectively investigate the incidence and type of DVT and evaluate the relationship between DVT and risk factors among all patients who underwent ACLR under uniform conditions consisting of mechanical prophylaxis, no medical prophylaxis, and preoperative and postoperative lower extremity venous ultrasonography.

Methods

Of the 114 patients who underwent arthroscopic primary ACLR at our hospital who did not have a compound ligament injury or revision surgery, 112 patients were included. Two patients were not examined. DVT evaluation consisted of whole-leg ultrasonography at 1 week after surgery. We evaluated age, sex, body mass index, comorbidities, operative time, tourniquet time, presence of concurrent surgery (meniscus repair/resection or osteochondral column grafting), and non-weight-bearing status at 1 week after surgery as risk factors for DVT.

Results

DVT was found in 33 (29.5%) of 112 patients. Of these, 22 (19.6%) had distal DVT and 11 (9.8%) had proximal DVT. Non-weight-bearing status at 1 week after surgery was a statistically significant risk factor for proximal DVT (P = .034).

Conclusions

Non-weight-bearing status is an independent risk factor for DVT, suggesting that early weight bearing may reduce the occurrence of DVT.

关节镜前交叉韧带重建围手术期深静脉血栓的相关因素

背景

据报道，与其他关节镜手术相比，前十字韧带重建（ACLR）与深静脉血栓（DVT）的发生率更高。本研究的目的是回顾性调查所有在机械预防、无药物预防以及术前和术后下肢静脉超声检查等统一条件下接受 ACLR 的患者 DVT 的发生率和类型，并评估 DVT 与危险因素的关系。 。

方法

在我院接受关节镜初次ACLR治疗的114例患者中，未进行复合韧带损伤或翻修手术的患者中，纳入112例。两名患者没有接受检查。DVT 评估包括术后 1 周的全腿超声检查。我们评估了年龄、性别、体重指数、合并症、手术时间、止血带时间、是否同时进行手术（半月板修复/切除或骨软骨柱移植）以及术后 1 周的非负重状态作为 DVT 的危险因素。 。

结果

112 名患者中有 33 名 (29.5%) 发现 DVT。其中，22 例 (19.6%) 患有远端 DVT，11 例 (9.8%) 患有近端 DVT。术后 1 周的非负重状态是近端 DVT 的一个具有统计学意义的危险因素 (P = .034)。

结论

非负重状态是DVT的独立危险因素，提示早期负重可能减少DVT的发生。
