Abstract

PURPOSE:

To assess the ability of anatomic double-bundle anterior cruciate ligament reconstruction in eliminating the pivot-shift phenomenon when identified by a quantitative measuring system (computer navigation or magnetic resonance imaging).

METHODS:

Literature review. Medline, Google Scholar and Cochrane Reviews computerized databases research using the keywords "pivot-shift," "anterior cruciate ligament reconstruction" and "double bundle." Twelve (7 in vitro and 5 in vivo) studies met the inclusion criteria.

RESULTS:

There was a wide variation in the absolute value of translation and rotation measured after anatomic double-bundle anterior cruciate ligament reconstruction. There were also differences in fixation methods, pivot-shift execution conditions, applied stresses during the pivot-shift, calculation methods and reference systems utilized by measurement systems.

CONCLUSIONS:

The double-bundle reconstruction was shown to over-constrain the knee with respect to the intact value, especially closer to knee extension. This review demonstrated that anatomic double-bundle anterior cruciate ligament reconstruction is able to eliminate pathological translations and rotations during the pivot-shift phenomenon, as identified by quantitative measurement systems.

LEVEL OF EVIDENCE:

Review of Level III studies, Level III.
