文题释义:
膝交叉韧带:为膝关节重要的稳定结构,呈铰链式连于股骨髁间窝及胫骨的髁间隆起之间,可防止胫骨沿股骨向前后移位。膝交叉韧带又可分为前后2条,前交叉韧带起自股骨外侧髁的内侧面,斜向前下方,止于胫骨髁间隆起的前部和内、外侧半月板的前角;后交叉韧带起自股骨内侧髁的外侧面,斜向后下方,止于胫骨髁间隆起的后部和外侧半月板的后角。
膝交叉韧带的功能:当膝关节活动时,2条韧带各有一部分纤维处于紧张状态。因此,除前交叉韧带能防止胫骨向前移位,后交叉韧带能防止腿骨向后移位外,还可限制膝关节的过伸、过屈及旋转活动,交叉韧带损伤常与胫侧副韧带或半月板损伤同时发生。
 
摘要
背景:以往研究显示,膝关节后交叉韧带胫骨止点撕脱骨折采用切开复位铆钉固定、空心螺钉固定或采用关节镜下后交叉韧带重建,忽略了后交叉韧带早期张力重建的重要性,因此疗效并不确定。目前在胫骨平台后交叉韧带附着点撕脱骨折固定方法的选择及如何恢复关节的解剖学稳定性问题上尚存在争议。
目的:观察新型固定支撑接骨板对胫骨平台后交叉韧带附着点撕脱骨折修复的稳定性作用。
方法/设计:研究为前瞻性、单中心、自身对照的临床试验,在中国河北省,沧州市中心医院完成。对纳入试验20例膝关节后交叉韧带胫骨止点撕脱骨折患者经后侧入路暴露骨折断端及损伤的后交叉韧带,直视下行骨折复位,采用新型支撑接骨板固定骨折断端,重建后交叉韧带。固定后随访3,12个月。主要观察指标为固定前、固定后3,12个月的膝关节HSS评分评估固定后患者膝关节功能恢复情况;试验的次要观察指标为固定前、固定后3,12个月 Lysholm膝关节评分,X射线,以CT,磁共振检查评估损伤膝关节修复后形态,以及固定后3,12个月患者满意度。试验在北美临床试验注册中心注册(NCT03059368)。试验经中国河北省沧州市中心医院伦理委员会批准。研究符合世界医学会制定的《赫尔辛基宣言》的要求。参与者本人对治疗方案和过程均知情同意,并签署知情同意书。
讨论:试验设计了一种有利于后交叉韧带早期张力重建的新型固定支撑接骨板固定方法,以此修复胫膝关节后交叉韧带胫骨止点撕脱骨折,以期最大限度的恢复膝关节解剖学稳定性,并验证其疗效,从而为膝关节后交叉韧带胫骨止点撕脱骨折治疗提供一定的试验依据,为解决最大限度的恢复膝关节解剖学稳定提供一种途径。

Abstract:

BACKGROUND: Avulsion fractures of the tibial attachment of the posterior cruciate ligament have been repaired using open reduction and rivet fixation, hollow screw fixation, or arthroscopic reconstruction of the posterior cruciate ligament. These methods ignore the importance of early tension reconstruction of the posterior cruciate ligament, so their efficacies are uncertain. Determining the optimal fixation method and how best to restore knee stability remain controversial.

OBJECTIVE: To observe the stability of new bone fixation plate for the repair of avulsion fracture of the tibial attachment of the posterior cruciate ligament.
METHODS/DESIGN: We will conduct a prospective, single-center, self-controlled, clinical trial at the Cangzhou Central Hospital, Hebei Province, China. Fracture fragments and the injured posterior cruciate ligament will be exposed in 20 patients with avulsion fracture of the tibial attachment of the posterior cruciate ligament through a posterior approach and open reduction. The posterior cruciate ligament will be reconstructed with a new type of bone plate. All patients will be followed for 3 and 12 months. Primary outcome: The Hospital for Special Surgery knee score will be used to evaluate knee function preoperatively and 3 and 12 months postoperatively. Secondary outcomes: Lysholm Knee Scoring Scale, X-ray, computed tomography, and magnetic resonance imaging will be used to assess knee morphology preoperatively and 3 and 12 months postoperatively. Patient satisfaction will also be assessed at 3 and 12 months postoperatively. The study protaol was registered at clinicaltrials.gov.NCT03059368. The study protocol has been approved by the Ethics Committee of Cangzhou Central Hospital of China. All protocols will be conducted in accordance with Declaration of Helsinki, formulated by the World Medical Association. Written informed consent will be provided by all participants.
DISCUSSION: This trial will evaluate a newly-designed plate fixation device for early tension reconstruction of the posterior cruciate ligament to repair avulsion fractures of the tibial attachment of the posterior cruciate ligament and restore knee stability. This trial will verify the plate’s efficacy, provide an experimental basis for treating avulsion fractures of the tibial attachment of the posterior cruciate ligament, and provide a method of maximizing knee stability.
