To investigate the repair method of type Ⅱc injury in the lateral meniscus popliteal tendon area based on the porcine knee joint.
Eighteen commercially available fresh porcine knee joints were randomly divided into 3 groups ( =6). After preparing a type Ⅱc injury in the lateral meniscus popliteal tendon area, and the anterior (group A), posterior (group B), or anterior and posterior (group C) of the popliteal hiatus (PH) was sutured by vertical mattress. The tension meter was used to apply gradient tensions of 2, 4, 6, 8, and 10 N along the tibial plateau horizontally, respectively, to pull the midpoint of the lateral meniscus popliteal tendon area. The displacement values before modeling, after modeling, and after suture were recorded. The reduction value of lateral meniscus displacement and reduction rate after suture were calculated and compared between groups.
There was no significant difference between groups ( >0.05) in the displacement values before modeling, after modeling, and after suture under different tensions. There was no significant difference between groups A and C ( >0.05) in the reduction value of lateral meniscus displacement and reduction rate after suture under different tensions. The reduction value of lateral meniscus displacement and reduction rate after suture in group B were lower than those in groups A and C. The reduction value of lateral meniscus displacement under tension of 2 N and the reduction rates under tensions of 2, 4, and 6 N between groups A and B showed significant differences ( <0.05). The reduction value of lateral meniscus displacement and the reduction rate under tensions of 2, 4, and 6 N between groups B and C showed significant differences ( <0.05).
Suturing the anterior area of PH is the key to repairing type Ⅱc injury of lateral meniscus popliteal tendon area.
基于猪膝关节研究外侧半月板腘肌腱区域Ⅱc型损伤的修复方法。
将18个市售新鲜猪膝关节随机分为3组（每组n = 6）。在外侧半月板腘肌腱区域制备Ⅱc型损伤后，采用垂直褥式缝合腘裂孔（PH）的前方（A组）、后方（B组）或前后方（C组）。使用张力计分别沿胫骨平台水平施加2、4、6、8和10 N的梯度张力，牵拉外侧半月板腘肌腱区域的中点。记录建模前、建模后及缝合后的位移值。计算并比较各组缝合后外侧半月板位移的复位值和复位率。
不同张力下，各组建模前、建模后及缝合后的位移值之间差异无统计学意义（P>0.05）。不同张力下，A组和C组缝合后外侧半月板位移的复位值和复位率之间差异无统计学意义（P>0.05）。B组缝合后外侧半月板位移的复位值和复位率低于A组和C组。A组和B组在2 N张力下外侧半月板位移的复位值以及在2、4和6 N张力下的复位率差异有统计学意义（P<0.05）。B组和C组在2、4和6 N张力下外侧半月板位移的复位值和复位率差异有统计学意义（P<0.05）。
缝合PH的前方区域是修复外侧半月板腘肌腱区域Ⅱc型损伤的关键。
