Effect of Concussions on the Performance of Running Backs and Wide Receivers in the National Football League
BACKGROUND: Concussion injuries are common in professional football players; however, their effect on player performance remains unclear.
PURPOSE: To quantify the effect of concussions on the performance of running backs and wide receivers in professional football players.Prevalence and Clinical Implications of Chondral Injuries After Hip Arthroscopic Surgery for Femoroacetabular Impingement Syndrome
BACKGROUND: Studies on the effect of partial- and full-thickness chondral damage of the hip on outcomes and the ability to achieve meaningful clinical outcomes are limited.
PURPOSE: To determine the effect of full- and partial-thickness chondral injuries on 2-year outcomes in patients undergoing hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS) compared with patients without chondral damage, and to identify significant predictors of achieving the patient acceptable symptomatic state (PASS) and minimal clinically important difference (MCID).Effect of Concussions on the Performance of Running Backs and Wide Receivers in the National Football League
BACKGROUND: Concussion injuries are common in professional football players; however, their effect on player performance remains unclear.
PURPOSE: To quantify the effect of concussions on the performance of running backs and wide receivers in professional football players.
STUDY DESIGN: Cohort study; Level of evidence, 3.Impact of ball weight on medial elbow torque in youth baseball pitchers
HYPOTHESIS: Our hypothesis was that an increase in ball weight would result in an increase in medial elbow torque during the pitching motion.
METHODS: Youth pitchers were recruited for this study and instructed to throw 5 maximum-effort fastballs from ground level using baseballs of 4 different weights: 85 g (3 oz), 113 g (4 oz), 142 g (5 oz), and 170 g (6 oz). The validated Motus sensor was used to assess medial elbow torque, arm speed, arm slot, and shoulder rotation for each pitch. Pitch velocity was measured using a radar gun. Relationships between baseball weight and pitching kinetics and/or kinematics were evaluated using linear mixed-effects analysis. An exit survey was conducted detailing the pitcher's evaluation of the ball weights used.Adductor Canal Block Versus Femoral Nerve Block for Pain Control After Anterior Cruciate Ligament Reconstruction: Case Closed? Response
Background: Femoral nerve block (FNB) is a commonly performed technique that has been proven to provide effective regional analgesia after anterior cruciate ligament (ACL) reconstruction. The adductor canal block (ACB) uses a similar sensory block around the knee while avoiding motor blockade of the quadriceps muscles.
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 2016Preoperative 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.Contemporary Management of the Hip Capsule During Arthroscopic Hip Preservation Surgery
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.
Diagnostic accuracy of ultrasound for rotator cuff tears
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.
