60.有關膝關節前十字韌帶(anterior cruciate ligament)之敘述,下列何者最不適當?
(A)防止脛骨前方移行(anterior tibial translation)
(B)在膝關節進行螺旋轉動復位機轉運動(screw-home mechanism)時,引導脛骨(tibia)做外旋轉 (external rotation)
(C)在膝關節伸直時(extension),後外側束(posterolateral bundle)是鬆弛的
(D)根據其脛骨的嵌入點(tibial insertion),分為前內側束(anteromedial bundle)及後外側束 (posterolateral bundle)

ACL
-
anteromedial bundle
-
more isometric
-
tightest in flexion
-
primarily responsible for restraining anterior tibial translation (anterior drawer test)
-
-
posterolateral bundleㅤㅤ
-
greater length changes
-
tightest in extension
-
primarily responsible for rotational stability (pivot shift test)ㅤㅤ
-
-
femoral attachment
-
lateral intercondylar ridge demarcates the anterior edge of the ACL
-
bifurcate ridge separates the anteromedial and posterolateral bundle attachmentㅤㅤ
-
-
tibial attachment
-
anterior tibia, between intercondylar eminences
