The purpose of this study was to evaluate the risk of lateral geniculate artery injury during suture passage through the lateral meniscus.
Sutures were passed via inside-out and outside-in techniques in 11 embalmed cadaveric knees. The number of punctures of the lateral geniculate artery and quantitative distances of needle penetrations were measured.
The lateral geniculate artery was punctured 7 times during inside-out passes through the junction of the middle and anterior third of the meniscus and 8 times during passes through the body of the middle third of the meniscus. During outside-in passes, there were 5 punctures when passing anterior to the lateral collateral ligament and 4 punctures when posterior to the ligament.
The lateral geniculate artery is in close proximity to the lateral meniscus and is punctured often during in vitro inside-out meniscal repair in the embalmed cadaver model.
Methods of meniscal repair that do not violate the lateral geniculate artery may offer improved rates of healing and should be further evaluated.
本研究旨在评估缝线穿过外侧半月板时外侧膝状动脉损伤的风险。
在11具防腐处理的尸体膝关节上，通过由内向外和由外向内技术穿入缝线。测量外侧膝状动脉的穿刺次数和针刺入的定量距离。
在由内向外穿过半月板中份与前份交界处时，外侧膝状动脉被穿刺7次；在穿过半月板中份体部时，被穿刺8次。在由外向内穿入时，在外侧副韧带前方穿入时有5次穿刺，在韧带后方穿入时有4次穿刺。
在防腐尸体模型中，外侧膝状动脉与外侧半月板毗邻，在体外由内向外半月板修复过程中常被穿刺。
不侵犯外侧膝状动脉的半月板修复方法可能会提高愈合率，应进一步评估。
