Micheli Anterior Cruciate Ligament Reconstruction in Skeletally Immature Youths: A Retrospective Case Series With a Mean 3-Year Follow-up.

Background: The management of anterior cruciate ligament (ACL) tears in the skeletally immature patient remains controversial. Outcomes on a physeal-sparing technique using the iliotibial band for combined intra-articular and extra-articular ACL reconstruction, called the Micheli technique, have been described and reported by the original authors.

Purpose: To evaluate the clinical outcomes of a physeal-sparing technique using the iliotibial band for combined intra-articular and extra-articular ACL reconstruction.

Association between acromial index and outcomes following arthroscopic repair of full-thickness rotator cuff tears.

Background: The purposes of this study were to evaluate the association between the acromial index and full-thickness rotator cuffs and to determine if the size of the acromial index was associated with outcomes in a cohort of patients who had had arthroscopic repair of full-thickness rotator cuff tears.

Methods: The acromial index was calculated for three groups by individual researchers: 115 patients (120 shoulders) who had arthroscopically repaired full-thickness rotator cuff tears without osteoarthritis (Group I); sixty-four patients (sixty-eight shoulders) who had intact rotator cuffs with osteoarthritis (Group II); and twenty-one patients (twenty-one shoulders) who had intact rotator cuffs, without osteoarthritis, and were managed for other pathology (Group III). The acromial index is the distance between the glenoid plane and the lateral border of the acromion divided by the distance between the glenoid plane and the lateral aspect of the humeral head.
