The effect of platelet-rich fibrin, platelet-rich plasma, and concentrated growth factor in the repair of full thickness rotator cuff tears.

Background: Rotator cuff lesions rank among the prevalent causes of shoulder pain. Combining surgical interventions with growth factors, scaffolds, and stem cell therapies can effectively decrease the likelihood of rotator cuff repair recurrence. Platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and concentrated growth factor (CGF), isolated from blood and rich in growth factors, have a critical role in cell migration, cell proliferation, and angiogenesis during the tissue regeneration process.

Three-Dimensional Finite Element Analysis of a Notched Insert Design for Reverse Total Shoulder Arthroplasty to Prevent Scapular Notching.

Purpose: Reverse total shoulder arthroplasty (RSA) is an effective treatment option for rotator cuff arthropathy. Scapular notching following RSA remains a major complication and has a high incidence. This finite element analysis (FEA) study provides a future reference for the optimal design of the insert component of RSA.

Does previous arthroscopic Bankart repair influence coracoid graft osteolysis in Latarjet procedure? A case-control study with computed tomography scan data.

Background: The Latarjet procedure is commonly performed in the treatment of recurrent shoulder instability and is also indicated as a salvage procedure for recurrence after failed arthroscopic Bankart repair. Although this procedure has shown success, there has been an increased awareness of complications in recent studies, especially graft osteolysis. Most relevant research has focused on the pathophysiology, incidence, or location of graft osteolysis or the risk factors for graft osteolysis; however, the data are limited to primary Latarjet procedures.

Six years of experience with the nationwide newborn ultrasonographic hip screening program in Turkey: a considerable change in the type of surgical interventions in developmental dysplasia of the hip.

This study aims to assess whether or not the nationwide newborn ultrasonographic hip screening program has influenced the rate of different types of surgical interventions performed in developmental dysplasia of the hip (DDH) in children in Turkey. A retrospective analysis of the nationwide data obtained from the National Registry System between January 1, 2015, and December 31, 2020, was carried out. The rate of minor and major surgical interventions was calculated by dividing the total number of primary closed/open reductions with or without tenotomies and the total number of primary pelvic or periacetabular osteotomies with or without femoral osteotomies by the total number of live births in the country per year, respectively.

Clinical Outcomes of Two-Stage Implantation in Reverse Shoulder Arthroplasty for Postinfectious End-Stage Glenohumeral Arthritis in Native Shoulders: A Single-Center Cohort Study with a Minimum 2-Year Follow-up.

Background: Septic arthritis of the shoulder is a rare but devastating condition that may lead to joint destruction. There are few studies and limited outcome data on shoulder arthroplasty for infected native shoulders with end-stage glenohumeral arthritis (GHA). Hence, this study aimed to demonstrate the clinical outcomes of two-stage implantation in reverse shoulder arthroplasty (RSA) using an antibiotic spacer in the first stage for this challenging condition.

Clinical and anatomical outcomes of isolated coracoclavicular fixation after acromioclavicular joint injury: is it stable enough or is additional horizontal fixation necessary?

Background: Recently, an emphasis has been put on anatomical reduction of acromioclavicular (AC) joint both in vertical and hortizontal planes for management of AC joint injuries due to persisting horizontal instability. Therefore, an additional AC fixation in horizontal plane has been recommended. However, relation between horizontal AC joint instability and clinical outcomes is still controversial.

Late diagnosis of subcoracoid type 6 AC dislocation: A case report.

Acromioclavicular (AC) dislocation is a common type of shoulder injury. Although the incidence of acromioclavicular dislocation is frequent, there are different opinions regarding the treatment. Many different techniques have been proposed for the surgical treatment of AC dislocations, but all these methods have been questioned from different angles, and the gold standard in terms of treatment has not yet been determined.
