MRI evaluation of a collagen meniscus implant: a systematic review.

Purpose: Good clinical results have been demonstrated in numerous clinical studies using the collagen meniscus implant (CMI); however, the MRI behaviour of the scaffold, evaluated with Genovese score, is limited to a few cases series. The purpose was to evaluate, using the Genovese score, the MRI behaviour of the CMI at different follow-up periods and investigate possible differences in the behaviour of lateral and medial CMI.

Methods: A comprehensive search was performed on PubMed, Medline, CINAHL, Cochrane, Embase and Google Scholar databases using various combinations of the following keywords: "collagen meniscus implant" or "collagen meniscal implant".

Long-term outcomes after repair of recurrent post-traumatic anterior shoulder instability: comparison of arthroscopic transglenoid suture and open Bankart reconstruction.

Purpose: The purpose of this study is to report long-term outcomes of the arthroscopic modified Caspari technique compared to an open capsular shift surgery to treat post-traumatic anterior shoulder recurrent instability. The hypothesis was that the open surgery group would show higher degenerative changes than to the modified Caspari technique group after a follow-up from 10 to 17 years.

Methods: One hundred and ten nonrandomized consecutive patients who underwent a surgical repair of recurrent unilateral anterior shoulder instability between 1990 and 1999 were retrospectively analyzed.

Prospective long-term outcomes of the medial collagen meniscus implant versus partial medial meniscectomy: a minimum 10-year follow-up study.

Background: Loss of meniscal tissue can be responsible for increased pain and decreased function.

Hypothesis: At a minimum 10-year follow-up, patients receiving a medial collagen meniscus implant (MCMI) would show better clinical, radiological, and magnetic resonance imaging (MRI) outcomes than patients treated with partial medial meniscectomy (PMM).

Study Design: Cohort study; Level of evidence 2.
