Two-staged application of PRP in arthroscopic rotator cuff repair: a matched-pair analysis.

Introduction: Failure rates after arthroscopic rotator cuff repair remain high. Platelet-rich plasma has gained interest as a potential biological augmentation to enhance bone-tendon healing. The purpose of this study is to evaluate the clinical and structural outcomes of repeated PRP application on rotator cuff repair.

Serial MRI evaluation following arthroscopic rotator cuff repair in double-row technique.

Introduction: So far, recurrent rotator cuff defects are described to occur in the early postoperative period after arthroscopic repair. The aim of this study was to evaluate the musculotendinous structure of the supraspinatus, as well as bone marrow edema or osteolysis after arthroscopic double-row repair. Therefore, magnetic resonance (MR) images were performed at defined intervals up to 2 years postoperatively.

Arthroscopic knotless-anchor rotator cuff repair: a clinical and radiological evaluation.

Purpose: The goal of this study was to evaluate the clinical and radiological results of the arthroscopic knotless-anchor Speed-Bridge technique, in particular the pattern and the rate of retears. The results were compared with a modified Suture-Bridge knot-tying technique (mDR). The hypothesis is that arthroscopic knotless-anchor Speed-Bridge rotator cuff repair is a sufficient technique to address supraspinatus tears and differs in pattern of retears when compared to mDR.

Arthroscopic double-row repair of the rotator cuff: a comparison of bio-absorbable and non-resorbable anchors regarding osseous reaction.

Purpose: The aim of this study was to analyse the osseous reaction after arthroscopic double-row rotator cuff repair using bio-absorbable poly-L-lactic acid (PLLA) and non-absorbable polyetheretherketone (PEEK) suture anchors. Focus of interest was the appearance of peri-implant fluid and anchor tunnel widening.

Methods: Thirty-six patients were evaluated at final follow-up (16 PLLA and 20 PEEK).
