  • Arthroscopic Femoral Osteochondroplasty With Capsular Plication for Osteochondroma of the Femoral Neck

    Abstract Osteochondromas of the femoral neck are a rare but challenging problem because of their distal location, which is difficult to access arthroscopically. Traditional methods of osteochondroma resection used invasive open approaches to manage these lesions. More recently, advances in hip arthroscopy have allowed expanded treatment of extra-articular hip conditions with a minimally invasive approach.

  • Do anatomic changes found in the throwing arm after a season of pitching resolve with off-season rest? A dynamic ultrasound study

    HYPOTHESIS: Our hypothesis was that seasonal adaptive changes in the ulnar collateral ligament (UCL), ulnohumeral joint space (UHJS), and glenohumeral internal rotation deficit (GIRD) of the pitching extremity would subsequently resolve with off-season rest.
    METHODS: Eleven collegiate pitchers underwent preseason, postseason, and off-season evaluations including physical examination; dynamic ultrasound imaging of the UCL and UHJS; and the short version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire. Ultrasound images were evaluated by 2 fellowship-trained musculoskeletal radiologists.

  • Osteochondral Allograft Transplantation in the Patellofemoral Joint: A Systematic Review

    BACKGROUND: The initial focus of cartilage restoration algorithms has been on the femur; however, the patellofemoral compartment accounts for 20% to 30% of significant symptomatic chondral pathologies. While patellofemoral compartment treatment involves a completely unique subset of comorbidities, with a comprehensive and thoughtful approach many patients may benefit from osteochondral allograft treatment.
    PURPOSE: To perform a systematic review of clinical outcomes and failure rates after osteochondral allograft transplantation (OCA) of the patellofemoral joint at a minimum 18-month follow-up.

  • The Impact of Workers' Compensation on Patient-Reported Outcomes Measurement Information System Upper Extremity and Legacy Outcome Measures in Patients Undergoing Arthroscopic Rotator Cuff Repair

    PURPOSE: To examine the preoperative performance of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Computer Adaptive Test (CAT) with respect to legacy scores in patients receiving rotator cuff repair (RCR). In addition, to define the impact of Workers' Compensation (WC) status on both performance and floor and ceiling effects.
    METHODS: The PROMIS UE CAT was administered preoperatively alongside legacy patient-reported outcome measures (PROMs) to patients undergoing isolated arthroscopic RCR from November 2017 to September 2018. Performance was assessed using Spearman correlation coefficients, and floor and ceiling effects were examined.

  • Superior Gluteal Reconstruction for Severe Hip Abductor Deficiency

    Abstract Abductor tendon tears are one of the common causes of recalcitrant laterally based hip pain and dysfunction. In most cases, abductor tendon tears are associated with chronic nontraumatic tearing of the gluteus medius tendon. Restoring abductor function of the hip by primary repair of the gluteus medius tendon has been reported to have good and excellent outcomes. However, primary repair might not be as effective for chronic detachment of the gluteus medius tendon with a wide separation from the femoral footprint or severe tendon loss.

  • 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).

    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.
