摘要:

文题释义:
膝关节后外侧复合体:主要包括3个核心结构:外侧副韧带、腘腓韧带和腘肌腱。外侧副韧带是限制膝关节内翻的初级稳定结构,同时外侧副韧带还具有对抗胫骨后移和外旋应力;腘肌腱和腘腓韧带在维持膝关节外旋稳定性上起着重要作用,是限制膝关节外旋的初级稳定结构。
膝关节后外侧复合体损伤:膝关节多发韧带损伤是一种高能量损伤,膝关节后外侧结构是维持膝关节稳定的重要结构,对于膝关节多发韧带损伤中合并的后外侧复合体损伤,如诊断或治疗不及时,常易引起膝关节慢性不稳定以及重建韧带失效等相关并发症。

背景:膝关节后外侧复合体损伤是膝关节多发韧带损伤的常见类型,后外侧复合体重建能够恢复膝关节后外侧稳定结构,重建膝关节稳定性。
目的:探讨取自体腓骨长肌腱移植物采用改良LaPrade法重建膝关节后外侧复合体损伤的可行性及临床疗效。
方法:2014年10月至2017年3月遵义医科大学附属医院骨科收治14例膝关节后交叉韧带合并膝关节后外侧复合体损伤的患者,一期同时重建后交叉韧带及后外侧复合体结构,膝关节后外侧复合体结构损伤均为Fanelli分型C性,采用改良LaPrade法取自体腓骨长肌腱功能重建,模拟重建后外侧复合体核心韧带的解剖形态和功能。术后随访大于1年,比较手术前后后向应力下胫骨后移距离、伸膝0°位内翻应力下外侧间隙张开距离、屈膝30°位拨号试验胫骨外旋角度变化,以及国际膝关节文献委员会分级和Lysholm评分。
结果与结论:①患者随访12-18个月,部分患者合并屈膝受限,所有患者无伸膝受限;②至末次随访,胫骨后移距离、外侧间隙张开距离及屈膝30°拨号试验结果均小于术前,差异均有显著性意义(P=0.000);③国际膝关节文献委员会分级由术前的D级改善为A级8例、B级6例;膝关节Lysholm评分由术前的(32.4±5.6)分提高至(82.7±6.4)分,差异有显著性意义(P=0.000);④提示采用改良LaPrade法取单根腓骨长肌腱可以完成后外侧复合体主要韧带的重建,模拟重建后外侧复合体核心韧带,术后膝关节功能恢复良好。

Abstract: BACKGROUND: Injury of the posterolateral complex of the knee joint is a common type of multiple ligament injuries of the knee joint. The reconstruction of the posterolateral complex can restore the posterior and lateral stability of the knee joint and rebuild the stability of the knee joint. 
OBJECTIVE: To discuss the feasibility and clinical effect of modified LaPrade method for functional reconstruction of posterolateral complex of knee with autograft peroneus longus tendon. 
METHODS: Fourteen patients with posterolateral complex and posterior cruciate ligament injuries who were treated in the Department of Orthopedics, Affiliated Hospital of Zunyi Medical University from October 2014 to March 2017 were enrolled in this study. Posterior cruciate ligament and posterolateral complex were simultaneously constructed in stage one. The injury of the posterolateral complex of the knee joint was Fanelli type C. Modified LaPrade method was used to functional reconstruction of posterolateral complex of knee with peroneus longus tendon. The anatomy and function of the core ligament of the posterolateral complex was simulated. Follow-up time was beyond 1 year. The tibia posterior displacement on stress radiographs, lateral compartment gapping on varus stress radiographs at 0° knee extension, and external rotation angle of tibia at 30° knee flexion were compared before and after surgery. The joint function was evaluated according to the score of International Knee Documentation Committee and Lysholm Knee score.
RESULTS AND CONCLUSION: (1) All patients were followed up for 12-18 months. All patients had no knee-length restriction, with flexion limitation in some patients. (2) At the last follow-up, the tibia posterior displacement on stress radiographs, lateral compartment gapping on varus stress radiographs and external rotation angle of tibia at 30° knee flexion were reduced from preoperation, with statistically significant differences (P=0.000). (3) The International Knee Documentation Committee function was corrected from D preoperatively to A in 8 cases and B in 6 cases postoperatively. The average Lysholm score was increased from (32.4±5.6) preoperatively to (82.7±6.4) postoperatively, and the differences were statistically significant (P=0.000). (4) It is indicated that with peroneus longus tendon, the anatomy and function of the core ligament of the posterolateral complex were simulated by modified LaPrade method to functional reconstruction of posterolateral complex of knee, and the postoperative knee function recovered well.
