Purpose
[edit | edit source]
To diagnose ruptures of the anterior cruciate liagment (ACL) by testing it's integrity ([2]).
Technique
[edit | edit source]
The patient lies on his back with 45° of hip flexion, 90° flexion of the knee and the tibia in neutral position. The fysiotherapist stabilizes the foot of the patient with his thigh and put both hands on the dorsal side of the proximal part of the tibia. The thumbs of the fysiotherapist are placed on the anterior part of the tibia plateau. The researcher performs an anterior-directed movement and assesses the degree of translation of the tibia. Grading is based on differences of degrees in translation of the affected side compared with the healthy side.
Evidence[edit | edit source]
[2] reported that the knee anterior draw test has a diagnostic accuracy of acute ACL ruptures (within 2 weeks of examination) of: 22.2% sensitivity and >95% specificity. The study reported the diagnostic accuracy of subacute/chronic ACL ruptures (more than 2 weeks before examination) is: 40.9% sensitivity and 98.4% specificity. It is important to note that in this study all examinations were performed under anesthesia; thus the diagnostic accuracy in physiotherapy clinical pracitice may be less. The knee anterior draw test, although widely used, is a poor diagnostic indicator of ACL ruptures, especially in the acute setting ([2]).
Both th Lachman test and the pivot shift test have been reported to have a greater diagnostic accuracy of ACL ruptures ([2]).
