Abstract

AIM OF THE STUDY

Ultrasound examination is widely used in orthopedic diagnostics, however sonographic evaluation of traumatic anterior cruciate ligament insufficiency is still inadequate. Aim of this study is to evaluate diagnostic capability of a new sonographically-guided test for diagnosing complete anterior cruciate ligament insufficiency.

MATERIAL AND METHODS

In 47 patients, with suspicion of unilateral anterior cruciate ligament injury (based on magnetic resonance imaging), the sonographically-guided test for anterior instability was performed. The translation of the intercondylar eminence against the patellar tendon was measured in both knees. Afterwards all patients underwent arthroscopy.

RESULTS

In 37 patients, with arthroscopically confirmed complete anterior cruciate ligament insufficiency, the mean anterior knee translation was 8.3 mm (SD = 2.8) in affected knee vs. 3 mm (SD = 1.1) in uninjured knee (p < 0.001). In 10 patients with no anterior cruciate ligament insufficiency the difference between body sides was not significant (2.6 mm, SD = 1.4 in injured knee vs. 2.5 mm, SD = 1.1 in uninjured joint; p < 0.7753).

CONCLUSIONS

The proposed test supports the clinician with fast and non-invasive examination that can facilitate evaluation of anterior knee instability.

摘要

研究目的

超声检查在骨科诊断中广泛应用，然而，对创伤性前交叉韧带不全的超声评估仍不充分。本研究的目的是评估一种新的超声引导下测试对诊断完全性前交叉韧带不全的诊断能力。

材料与方法

对47例疑似单侧前交叉韧带损伤（基于磁共振成像）的患者进行了超声引导下的前交叉韧带不稳定测试。测量双膝髁间隆起相对于髌腱的平移。之后，所有患者均接受了关节镜检查。

结果

在37例经关节镜证实为完全性前交叉韧带不全的患者中，患侧膝关节的平均前膝平移为8.3毫米（标准差=2.8），而未受伤膝关节为3毫米（标准差=1.1）（p<0.001）。在10例无前交叉韧带不全的患者中，双侧差异不显著（受伤膝关节为2.6毫米，标准差=1.4；未受伤关节为2.5毫米，标准差=1.1；p<0.7753）。
