Preventing Tommy John Surgery: The Identification of Trends in Pitch Selection, Velocity, and Spin Rate Before Ulnar Collateral Ligament Reconstruction in Major League Baseball Pitchers.

Background: Ulnar collateral ligament (UCL) reconstruction is a common surgery among Major League Baseball (MLB) pitchers that results in a significant number of missed games. Little has been reported regarding game-by-game trends that can identify those on the verge of becoming injured.

Purpose: To determine if there is a patterned change in MLB pitchers' pitch selection, velocity, or spin rate in games leading up to Tommy John surgery that may predict subsequent UCL surgery.

Do Intra-articular Corticosteroid Injections Prior to Total Knee Arthroplasty Increase Postoperative Complication Rates: A Retrospective Review.

There is conflicting literature suggesting that intra-articular corticosteroid injections before total knee arthroplasty (TKA) may lead to an increase in the rate of postoperative complications, specifically periprosthetic joint infection (PJI). Thus, this retrospective review of all TKAs performed at a large, urban hospital will add valuable evidence to help guide future patient care. After exclusion criteria, we retrospectively reviewed 417 patients who received a TKA from a group of fellowship-trained orthopaedic surgeons between 2009 and 2016 at a single academic medical center.

Is There an Association Between Authors' Conflicts of Interest and Outcomes in Clinical Studies Involving Autologous Chondrocyte Implantation?

Background: Autologous chondrocyte implantation (ACI) is an increasingly popular technique for the treatment of articular cartilage defects. Because several companies have financial interests in ACI, it is important to consider possible conflicts of interest when evaluating studies reporting outcomes of ACI.

Purpose: To determine whether there is an association between authors' financial conflicts of interest and the outcomes of ACI studies.

A systematic review of upper extremity neuropathy following total hip arthroplasty.

Background: There is a paucity of literature describing upper extremity neuropathy following the procedure. We performed a systematic review of upper extremity neuropathy following total hip arthroplasty (THA) to provide characteristics regarding the incidence, suspected aetiology, and outcomes of such complications.

Methods: A systematic review of the literature was performed which investigated the COCHRANE and Medline databases regarding "peripheral neuropathy total hip arthroplasty" and "nerve palsy associated total hip arthroplasty.

Return to Play in Amateur Soccer Players Undergoing Hip Arthroscopy: Short- to Mid-Term Follow-Up.

Purpose: To describe patient-reported outcomes (PROs) and return to play at any level in amateur soccer players undergoing hip arthroscopy for femoroacetabular impingement syndrome at short- to mid-term follow-up.

Methods: Data were prospectively collected and retrospectively reviewed for patients who underwent hip arthroscopy between March 2009 and June 2014. Patients who participated in amateur soccer within 1 year prior to surgery and intended to return to their sport after hip arthroscopy for femoroacetabular impingement syndrome were considered for inclusion in our study.

Greater Trochanteric Pain Syndrome: An Intraoperative Endoscopic Classification System with Pearls to Surgical Techniques and Rehabilitation Protocols.

Over the past decade, understanding of disorders compromising greater trochanteric pain syndrome (GTPS) has increased dramatically. Nonsurgical treatment options include physical rehabilitation and activity modification, anti-inflammatory as well as biologic injections into the peritrochanteric compartment, and administration of oral analgesics. Multiple open and endoscopic treatment options exist when nonsurgical management is unsuccessful in patients with refractory lateral-sided hip pain, with or without weakness.

Effect of marital status on patient-reported outcomes following total hip arthroplasty: a matched analysis with minimum 2-year follow-up.

Introduction: Mental health and patient expectation have been identified as key predictors of recovery following THA; however, there is limited literature examining the effects of social support and marital status on patient-reported outcomes (PROs).

Methods: Data were prospectively collected and retrospectively reviewed for patients who underwent THA between July 2008 and January 2016. Patients were included if they underwent primary THA during this period and if they had documented preoperative marital status of married, divorced, or never married.
