Little is known regarding walking characteristics, volume, and intensity evaluated in laboratory and free-living conditions and whether these measures differ between those with FAIS and uninjured individuals.

Objective: To examine the differences in laboratory gait measures and free-living step-based metrics between individuals with FAIS and uninjured control participants.

Outcomes and Proportions of Subsequent Contralateral Sports Hernia Repair Following Primary Unilateral Repair.

Background: In the event that nonoperative treatment for sports hernia fails, surgical repair may be warranted. Bilateral repair can occur in up to 45% of surgically treated patients.

Purpose: To investigate the clinical outcomes of athletes who underwent unilateral sports hernia repair and determine the proportion of patients who required contralateral sports hernia repair.

Fixation strength in arthroscopic labral repair of the hip: A head-to-head comparison of the biomechanical performance of a biocompatible vs. all-suture anchor in the setting of acetabuloplasty.

Much is known about the biomechanical performance of various types of suture anchors commonly used for labral fixation in the shoulder; however, similar studies in the hip are less common. We sought to compare all-suture and polyether ether ketone small-diameter anchors in the setting of labral repair during hip arthroscopy, with and without acetabuloplasty. We hypothesized that the biomechanical properties of the all-suture group when compared to polyether ether ketone anchors would be similar amongst native acetabula and significantly less following acetabuloplasty and that pullout forces would be reduced in the anterior and inferior regions of the acetabulum compared to the superior region.

Outcomes of Double-Row Rotator Cuff Repair Using a Novel All-Suture Soft Anchor Medial Row.

Clinical outcomes of osteochondritis dissecans lesions of the capitellum treated with arthroscopy with a mean follow-up period of 8.3 years.

Background And Hypothesis: Although numerous studies exist evaluating the short-term clinical outcomes of patients who have undergone elbow arthroscopy for osteochondritis dissecans (OCD) of the capitellum, the literature on minimum 2-year clinical outcomes in a large cohort of patients is limited. We hypothesized that the clinical outcomes of patients treated arthroscopically for OCD of the capitellum would be favorable, with improved postoperative subjective functional and pain scores and with an acceptable return-to-play rate.

Methods: A retrospective analysis of a prospectively collected surgical database was performed to identify all patients treated surgically for OCD of the capitellum at our institution from January 2001 to August 2018.

Clinical outcomes and return to play in softball players following SLAP repair or biceps tenodesis.

Background: Shoulder pain due to labral tears and biceps tendonitis is commonly found in softball players. Surgical options include labral repair and biceps tenodesis. Although past studies are limited by heterogeneous study groups from multiple sports, this is the first study that assesses clinical outcomes and return to play rates for fast-pitch softball players.

Endoscopic Gluteus Medius Repair.

Endoscopic gluteus medius repair is indicated after failed conservative management for debilitating peritrochanteric hip pain. In our experience, most of these surgeries are performed on women, 45 to 75 years old. Often for undersurface high-grade partial-thickness tears and some small full-thickness tears, a single-row repair technique is performed.

Endoscopic Gluteus Medius Repair Replicates Open, Knotless Repair With Similar Cyclic Loading Properties: A Cadaveric Study.

Purpose: To compare the repair strength, gap formation, and mode of failure between endoscopic and open double-row gluteus medius repairs in a cadaveric model.

Methods: Six pairs of fresh-frozen human cadavers were used in this study. Gluteus medius tears were created in an open fashion and then repaired with either open or endoscopic techniques.

In-line Pullout Strength of 2 Acetabular Fixation Methods for Ligamentum Teres Reconstruction of the Hip: A Cadaveric Study.

Background: Ligamentum teres (LT) reconstruction is an appropriate alternative in select cases of LT full-thickness tears, resulting in hip micro- or macroinstability. Graft fixation at the acetabular fossa is critical to achieving the best functional results.

Purpose: The purpose of this study is to compare the pullout strength of 2 graft fixation methods used for LT reconstruction of the hip.

Early Complications of Ulnar Collateral Ligament Repair With Collagen-Coated Suture Tape Augmentation.

Background: Recent innovative techniques have led to renewed interest in ulnar collateral ligament (UCL) repair. Although early outcome data regarding the clinical outcome of overhead athletes undergoing UCL repair with augmentation have been encouraging, long-term data are still needed to evaluate both the appropriate indications and success rate for this procedure.

Purpose: To describe and evaluate the acute complications seen in a large cohort of patients who underwent UCL repair with internal brace augmentation at a single institution.

Clinical Outcomes and Return to Play in Youth Overhead Athletes After Medial Epicondyle Fractures Treated With Open Reduction and Internal Fixation.

Background: There is limited literature regarding outcomes after operative treatment of displaced medial epicondyle avulsion fractures in adolescent athletes. Most studies have had a relatively small sample size and have not assessed return to play of the overhead athlete.

Purpose: To examine return to play and outcomes of youth overhead athletes who underwent open reduction and internal fixation (ORIF) with screw fixation.

Outcomes of Open and Endoscopic Repairs of Chronic Partial- and Full-Thickness Proximal Hamstring Tendon Tears: A Multicenter Study With Minimum 2-Year Follow-up.

Background: The preponderance of literature on the repair of proximal hamstring tendon tears focuses on the acute phase (<4 weeks). As such, there is a paucity of data reporting on the outcomes of chronic proximal hamstring tears.

Purpose: To report minimum 2-year postoperative patient-reported outcome (PRO) scores, visual analog scale (VAS) for pain, and patient satisfaction from patients who underwent open or endoscopic repair of partial- and full-thickness chronic proximal hamstring tendon tears.

Baseball Pitching Biomechanics Shortly After Ulnar Collateral Ligament Repair.

Background: The probability of returning to competition for injured baseball pitchers is similar after ulnar collateral ligament (UCL) repair as after UCL reconstruction, but the time to return is significantly quicker after UCL repair. Previous research has found no differences in pitching biomechanics between pitchers with and without a history of UCL reconstruction, but pitching biomechanics after UCL repair has not been studied.

Hypothesis: There will be significant differences in pitching biomechanics between pitchers returning to play after UCL repair and pitchers with no injury history.

Portal Placement and Biomechanical Performance of Endoscopic Proximal Hamstring Repair.

Background: Proximal hamstring tendon avulsions are debilitating and commonly cause pain, weakness, and functional limitations. Open surgical repair has been the standard, but improved endoscopic techniques have enabled proximal hamstring fixation with decreased risk of infection and numbness, without the morbidity of a large incision.

Purpose/hypothesis: The purpose was to (1) describe pertinent anatomy surrounding the proximal hamstring origin in relation to 4 endoscopic portal sites and (2) test for biomechanical differences between open and endoscopic repair.

Ulnar Collateral Ligament Repair With Collagen-Dipped FiberTape Augmentation in Overhead-Throwing Athletes.

Background: There has been a renewed interest in ulnar collateral ligament (UCL) repair in overhead athletes because of a greater understanding of UCL injuries, an improvement in fixation technology, and the extensive rehabilitation time to return to play.

Purpose/hypothesis: To evaluate the clinical outcomes of a novel technique of UCL repair with internal brace augmentation in overhead throwers.

Study Design: Case series; Level of evidence, 4.

Athletic Pubalgia Secondary to Rectus Abdominis-Adductor Longus Aponeurotic Plate Injury: Diagnosis, Management, and Operative Treatment of 100 Competitive Athletes.

Background: A rectus abdominis-adductor longus (RA-AL) aponeurotic plate injury, commonly associated with athletic pubalgia, sports hernia, or a core muscle injury, causes significant dysfunction in athletes. Increased recognition of this specific injury distinct from inguinal hernia abnormalities has led to better management of this debilitating condition.

Hypothesis: Surgical repair of RA-AL aponeurotic plate injuries will result in decreased symptoms and high rates of return to play.

Rotator Cuff Repair in Adolescent Athletes.

Background: Rotator cuff tears are rare injuries in adolescents but cause significant morbidity if unrecognized. Previous literature on rotator cuff repairs in adolescents is limited to small case series, with few data to guide treatment.

Hypothesis: Adolescent patients would have excellent functional outcome scores and return to the same level of sports participation after rotator cuff repair but would have some difficulty with returning to overhead sports.

Mini-open Incision Sports Hernia Repair: A Surgical Technique for Core Muscle Injury.

One cause of groin pain in highly active patients may be a core muscle injury, commonly referred to as sports hernia. When patients fail nonoperative management, there are a number of surgical options that may be pursued. Typically, they will involve the direct repair of the rectus abdominis back to the pubis.

Comparison of Anterior Cruciate Ligament Graft Isometry between Paired Femoral and Tibial Tunnels.

Accurate tunnel placement is important for a successful anterior cruciate ligament (ACL) reconstruction. Controversy exists concerning the preferred method of femoral tunnel preparation, with proponents of both medial portal and transtibial drilling techniques. Current ACL literature suggests that placement of the femoral ACL attachment site posterior or "low" in the ACL footprint leads to more anatomically correct ACL mechanics and better rotational control.

Return to play following metacarpal fractures in football players.

Background: Metacarpal fractures are common in football players and lead to time away from competition, but current operative treatment data is limited. The purpose of this study was to examine demographics and outcomes of football players who underwent operative fixation for metacarpal fractures.

Methods: Retrospective review from 2009 to 2012 of any football player surgically treated at one institution for a metacarpal fracture.
