摘要目的:初步探讨关节镜下评估胫骨平台骨折患者合并关节内半月板撕裂和交叉韧带损伤的类型。方法:回顾性分析2016年1月至2019年1月河北医科大学第三医院创伤急救中心收治的216例（216膝）行闭合复位内固定手术治疗的胫骨平台骨折患者的临床资料。男性147例，女性69例，年龄46.3岁（范围：18~80岁）。患者均采用双反牵引复位器将移位的骨折块闭合复位，之后采用经皮微创接骨板固定技术加压固定。术中行关节镜探查半月板的稳定性和交叉韧带的连续性，记录并分析患者半月板撕裂和交叉韧带损伤的类型及比例。结果:216例胫骨平台骨折患者中，105例（48.6%）合并半月板损伤，37例（17.1%）合并交叉韧带损伤。半月板损伤类型中，纵行撕裂占43.8% （46/105），最常见于Schatzker Ⅱ型骨折（58.7%，27/46）；半月板复杂性撕裂占17.1%（18/105），最常见于Schatzker Ⅴ型骨折（9/18）；交叉韧带损伤类型中，前交叉韧带损伤24例（64.9%，24/37），后交叉韧带损伤13例（35.1%，13/37）。撕脱骨折是前交叉韧带损伤中最常见的类型，占41.7% （13/24），且均发生在胫骨止点侧。结论:胫骨平台骨折合并半月板损伤和交叉韧带损伤常见的损伤类型为半月板纵行撕裂和前交叉韧带损伤。

abstractsObjectives:To investigate the types of meniscal tears and cruciate ligamentous injuries in patients with tibial plateau fracture(TPF) following arthroscopic examination.Methods:The clinical data of 216 patients with TPF who underwent closed reduction and internal fixation (CRIF) from January 2016 to January 2019 at Trauma Emergency center, the Third Hospital of Hebei Medical University were analyzed retrospectively. There were 147 males (147 knees) and 69 females (69 knees),aged 46.3 years (range: 18 to 80 years). All patients underwent closed reduction for the displaced fracture fragment with the use of bidirectional rapid redactor,and minimally invasive percutaneous plate osteosynthesis. Intra-operative arthroscopic examination was performed to exam the stability of meniscus and the continuity of cruciate ligamentous after CRIF. The percentages and types of meniscal tears and cruciate ligamentous injuries were recorded.Results:The overall percentages of meniscal tears associated with TPFs was 48.6%(105/216). The most common pattern of meniscal tears was longitudinal tears, accounting for 43.8% (46/105), and it occurred most frequently in Schatzker type Ⅱ (58.7%, 27/46). Furthermore, the percentage of meniscal complex tears was 17.1% (18/105), occurring most frequently in Schatzker type Ⅴ (9/18). The overall percentage of cruciate ligamentous injuries associated with TPFs was 17.1% (37/216), and the percentages of anterior cruciate ligament (ACL) injuries was 64.9%(24/37), the percentage of posterior cruciate ligament injuries was 35.1%(13/37). Avulsion fracture was the most common pattern in ACL injuries, accounting for 41.7% (13/24), and all occurred in the tibial insertion site.Conclusions:In the present study, the percentages of meniscal tears and ligamentous injuries in TPFs are 48.6% and 17.1%, respectively. The most common types are meniscal longitudinal tears and ACL injury, occurring most frequently in Schatzker type Ⅱ and Ⅳ, respectively. Recognition of concomitant meniscal tears and cruciate ligamentous injuries in TPFs is helpful for trauma physicians to choose the best surgical treatment.
