T. Mononen et al., INSTRUMENTED MEASUREMENT OF ANTERIOR-POSTERIOR TRANSLATION IN KNEES WITH CHRONIC ANTERIOR CRUCIATE LIGAMENT TEAR, Archives of orthopaedic and trauma surgery, 116(5), 1997, pp. 283-286
Anteroposterior translation of the knee joint was measured with a Knee
Signature System device on 12 women and 14 men with a unilateral, chr
onic, isolated, anterior cruciate ligament (ACL) tear. A control group
with stable knees consisted of 10 women and 10 men. Anterior translat
ion at 178 N load of the uninjured knees was 8.0 mm (+/- 2.2 mm) and i
n knees with an ACL tear, 14.2 mm (+/- 4.2 mm). Corresponding values f
or anteroposterior translation were 12.1 mm (+/- 2.5 mm) and 19.3 mm (
+/- 4.9 mm), respectively. A difference of 3 mm or more in anteroposte
rior translation at 178 N load between injured and uninjured knees ind
icated an ACL tear with 85% specificity and 88% sensitivity.
