Hamstring Injury Trends in Major and Minor League Baseball: Epidemiological Findings From the Major League Baseball Health and Injury Tracking System
BACKGROUND: Hamstring strains are the most common injury for professional baseball players and can result in significant time on the disabled list. To date, no study has reported the current trends in hamstring strains in professional baseball.
HYPOTHESIS: Professional baseball players would have an increased incidence of hamstring strains from 2011 through 2016
Preoperative Performance of the PROMIS in Patients Undergoing Hip Arthroscopic Surgery for Femoroacetabular Impingement Syndrome
BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) is being increasingly evaluated for use in orthopaedic surgery. The performance of the PROMIS in patients undergoing hip preservation surgery is unknown.
PURPOSE: To investigate the psychometric performance of the PROMIS compared with legacy patient-reported outcome measures (PROMs) in patients indicated for hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS).
Concussions in the National Basketball Association: Analysis of Incidence, Return to Play, and Performance From 1999 to 2018
BACKGROUND: The effect of concussions on professional athletes has been investigated in many sports. However, few studies have evaluated concussions in National Basketball Association (NBA) players.
HYPOTHESIS: We hypothesized that concussion incidence has increased, yet the return-to-play (RTP) rate will remain high following the institution of the NBA concussion policy (NBACP). We also hypothesized that the incidence of repeat concussions will be similar to first occurrences and that player performance and game availability will not be significantly affected by sustaining a concussion.
PURPOSE OF REVIEW: The importance of the hip capsule and its effect on hip biomechanics, functional outcomes, and hip arthroscopy success rates has been demonstrated in recent studies. These results have led to a shift in management of the hip capsule, where an increasing number of surgeons routinely perform complete capsular closure. The purpose of this review is to highlight recent studies evaluating the hip capsule and describe contemporary capsular management and repair.
Abstract Ultrasonography (US) is an inexpensive, convenient, and effective tool that can be used to evaluate the shoulder. It does not expose the patient to harmful radiation and can be used to evaluate the musculoskeletal system dynamically. Additionally, US is not subject to metal artifacts when evaluating patients with previously placed hardware. Over the years, US has been found to be reliable and accurate for diagnosing rotator cuff tears (RCTs), despite its operatordependence. The usage of US for diagnosing RCTs in orthopedic practice varies depending on practitioners' familiarity with the exam and the availability of experienced technicians. The purpose of this article is to review the diagnostic accuracy of US for identifying RCTs.
Response to: "Regarding 'Risk Factors for Postoperative Opioid Use in Arthroscopic Meniscal Surgery'"
We would like to thank Dr. Park for his valuable comments on our article concerning postoperative opioid use in arthroscopic meniscal surgery. He inquired about the role of comorbid psychiatric diseases, intraoperative and postoperative nerve blocks, and adjustment for the role of postoperative nonopioid analgesics in the outcomes of our study.
Results of total shoulder arthroplasty in patients aged 55 years or younger versus those older than 55 years: an analysis of 1135 patients with over 2 years of follow-up
BACKGROUND: The results of anatomic total shoulder arthroplasty (TSA) in younger patients have not been clearly elucidated. The purpose of this study was to compare early outcomes after TSA in patients aged 55 years or younger versus patients older than 55 years.
METHODS: A total of 1135 patients who were treated with TSA for glenohumeral arthritis and had a mean follow-up period of over 4 years were retrospectively reviewed. Etiologies included osteoarthritis (n = 1044), osteonecrosis (n = 35), inflammatory arthritis (n = 34), and post-traumatic arthritis (n = 22). Validated outcome measures, range of motion, and patient satisfaction were recorded. Preoperative and postoperative metrics were compared, and a multivariate analysis was performed to isolate age from sex, body mass index, previous surgery, and diagnosis as independent factors.
How Much Do Psychological Factors Affect Lack of Return to Play After Anterior Cruciate Ligament Reconstruction? A Systematic Review
BACKGROUND: Variables affecting return to sport after anterior cruciate ligament reconstruction (ACLR) are multifactorial. The nonphysical factors germane to successful return to play (RTP) are being increasingly recognized.
PURPOSE: To (1) evaluate the available evidence base for psychological factors relating to RTP after ACLR, (2) identify psychological factors affecting RTP after ACLR, and (3) understand currently available metrics used to assess psychological RTP readiness.
Influence of Acetabular Labral Tear Length on Outcomes After Hip Arthroscopy for Femoroacetabular Impingement Syndrome With Capsular Plication
BACKGROUND: The literature on the effects of labral tear on patient-reported outcomes, midterm pain, and overall patient satisfaction is limited.
PURPOSE: To determine the effect of labral tear length on postoperative outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAIS).
HYPOTHESIS: Among patients undergoing shoulder arthroplasty (SA), female patients would have worse outcomes than their male counterparts.
METHODS: A multicenter prospective cohort of 2364 patients (1365 female and 999 male patients) treated with total SA or reverse total SA from 2007 to 2015 was retrospectively analyzed. Results were assessed using several validated outcome measures and range-of-motion testing. A multivariable analysis identified differences in preoperative values, postoperative values, and preoperative-to-postoperative improvements while adjusting for possible confounders.
