Abstract

PURPOSE:

To clarify the effects of re-notchplasty on magnetic resonance imaging (MRI) for evaluating the reconstructed anterior cruciate ligament (ACL).

TYPE OF STUDY:

Observational cohort study.

METHODS:

Twenty-one patients who underwent re-notchplasty at second-look arthroscopy were examined. The MRI findings of the reconstructed ACL were classified as having either high, intermediate, or low intensity based on the clarity of appearance.

RESULTS:

The impinged group at second-look arthroscopy underwent re-notchplasty. Twelve patients continued to show a high signal intensity that did not decrease after re-notchplasty at the second-look operation. In contrast, 9 impinged ACL grafts showed a decreased signal intensity of the graft after re-notchplasty.

CONCLUSIONS:

In this study, 9 cases showed a decreased intensity and were considered to have an impingement at the notch, which thus influenced the maturity process by decreasing the compression on the reconstructed ACL.
