PURPOSE The purpose of this study was to evaluate the number of colony-forming units (CFUs) derived from concentrated bone marrow aspirates (BMAs) that were processed following arthroscopic harvest from either the proximal humerus or the body of the ilium during biologic augmentation of the rotator cuff and acetabular labral repairs. METHODS Between November 2014 and January 2019, BMA was harvested from the proximal humerus (n = 89) and the body of the ilium (n = 30) during arthroscopic surgery....

ABSTRACT Background Traditional shoulder physical examination (PE) tests have suboptimal sensitivity for detection of supraspinatus full-thickness tears (FTTs). Therefore, clinicians may continue to suspect FTTs in some patients with negative rotator cuff PE tests and turn to magnetic resonance imaging (MRI) for definitive diagnosis. Consequently, there is a need for a secondary screening test that can accurately rule out FTTs in these patients to better inform clinicians which patients should u...

The purpose of this study was to evaluate the histologic features of the caprine labrum, with emphasis on the chondrolabral junction, with the goal of informing the feasibility of the goat as an animal model. The left hip joint of six adolescent Spanish goats (Capra pyrenaica) was harvested and subjected to anatomical and histological assessments. Human acetabular and femoral head samples, collected during total hip arthroplasty, served as comparison samples. The caprine labrum was found to cons...

Abstract: Purpose The purpose of this study is to analyze mid-term outcomes after arthroscopic synovectomy of both diffuse and nodular hip PVNS. Methods This is a retrospective case series of patients that underwent hip arthroscopy for hip PVNS with a single senior surgeon between 2007 and 2016. Inclusion criteria were MRI evidence, arthroscopic visualization, and/or histological confirmation of PVNS; and a minimum of three years follow-up. Concomitant pathology such as FAI were also treated at ...

Abstract Purpose The primary purpose of this study was to evaluate the number and concentration of progenitors of the bone marrow aspirate (BMA) harvest from the body of the ilium in comparison to other established aspiration sites. Methods The inclusion criteria consisted of primary hip arthroscopy for acetabular labral tear. BMA was performed by placing an aspiration needle into the body of ilium just proximal to the sourcil in 33 patients. The BMA was centrifuged and processed in the operatin...

Abstract Background Periprosthetic joint infection (PJI) is a major complication of total joint arthroplasty (TJA). The intraoperative splash basin has been found to be a potential source of contamination. Although consensus recommendations against the use of splash basin have been made, splash basin use continues to be taught and utilized in practice. This study aims to investigate the effect of dilute betadine addition to the sterile water contents (0.02% solution) of the splash basin on conta...

Abstract Purpose The purpose of this study is to evaluate the short-term outcomes of endoscopic repair of full-thickness gluteus medius and minimus tendon tears with a minimum of 2-year follow-up and add to the paucity of literature on abductor tendon tears. Methods All patients who underwent endoscopic abductor tendon repair between December 2013 and August 2017 were prospectively evaluated. The inclusion criteria for this study were primary full-thickness gluteal tendon tears and at least 2-ye...

Osteonecrosis of the femoral head (ONFH) is a progressive disease that leads to collapse and the development of secondary arthritis. The preferred management of ONFH remains controversial. Arthroscopic-assisted management of ONFH is a new and evolving approach for hip preservation. We hypothesis that arthroscopy is able to improve ONFH outcomes by achieving accurate and minimally invasive decompression while successfully addressing concomitant intraarticular pathologies resulting in reliable mid...
