#1
Christine D Pollard, Justin A Ter Har, J J Hannigan, Marc F Norcross
Background: Lower extremity injuries are common among runners. Recent trends in footwear have included minimal and maximal running shoe types. Maximal running shoes are unique because they provide the runner with a highly cushioned midsole in both the rearfoot and forefoot. However, little is known about how maximal shoes influence running biomechanics. Purpose: To examine the influence of maximal running shoes on biomechanics before and after a 5-km (5K) run as compared with neutral running shoes...

Florian B Imhoff, Knut Beitzel, Philip Zakko, Elifho Obopilwe, Andreas Voss, Bastian Scheiderer, Daichi Morikawa, Augustus D Mazzocca, Robert A Arciero, Andreas B Imhoff
Background: Derotational osteotomy of the distal femur allows the anatomic treatment of patellofemoral maltracking due to increased femoral antetorsion. However, such rotational osteotomy procedures have a high potential of intended/unintended changes of frontal alignment. Purpose/Hypothesis: The purpose of this study was to perform derotational osteotomy of the distal femur and to demonstrate the utility of a novel trigonometric approach to address 3-dimensional (3D) changes on 2-dimensional imaging (axial computed tomography [CT] and frontal-plane radiography)...

#3
Krishn Khanna, Abhinav Janghala, Nirav K Pandya
Background: Posterior hamstring harvest has been described in the adult population in a limited fashion, but no study is available describing the use of posterior hamstring harvest in an active pediatric and adolescent cohort. At times, surgeons may be faced with a challenging anterior harvest due to patient anatomic characteristics, particularly the anatomic features and size of the pes tendons. Clinicians need to have multiple harvest approaches at their disposal. Complications with hamstring harvest such as premature graft transection are more problematic in this population due to higher failure rates with allograft tissue...

Kåre Amtoft Nissen, Niclas Højgaard Eysturoy, Torsten Grønbech Nielsen, Martin Lind
Background: The literature on revision anterior cruciate ligament (ACL) reconstruction (ACLR) outcomes is generally sparse, but previous studies have demonstrated that autograft use results in improved sports function and patient-reported outcome measures compared with allograft. However, knowledge is still lacking regarding the impact of graft type on rates of re-revision. Purpose: To investigate the clinical outcomes and failure rates of revision ACLRs performed with either allograft or autograft...

Syed Mohammed Taif Rizvi, Patrick Lam, George A C Murrell
Background: After rotator cuff repair, some patients have ongoing problems significant enough to warrant presentation to a clinic for reassessment. Purpose/Hypothesis: The purpose of this study was to determine whether this cohort of patients was more likely to have a healed rotator cuff. We hypothesized that patients who had an unscheduled postoperative visit were more likely to have a healed rotator cuff than those who did not have an unscheduled postoperative visit...

#7
Geoffroy Nourissat, Michel Calò, Bernard Montalvan, Jacques Parier
Background: Os acromiale is a rare condition mostly reported in the literature through case reports, imaging studies, or reports of surgical treatment. This condition is the result of nonunion of growth plates of the acromion during the natural developmental process that occurs between 15 and 25 years of age. Its incidence is low, and few studies are available in the literature on athletes with high functional demands, and particularly on athletes within a specific sport. Purpose: To collect epidemiological data and to report the amount of time out of play as well as the type of treatment and its efficiency in professional tennis players...

Nikhil Kumar, Tracey P Bastrom, M Morgan Dennis, Andrew T Pennock, Eric W Edmonds
Background: Recurrent patellar instability is commonly treated with medial patellofemoral ligament reconstruction (MPFLR), and the use of allograft in anterior cruciate ligament reconstructions has demonstrated inferior outcomes. Purpose: To compare the outcomes of allografts versus autografts in adolescent MPFLR for patellar instability. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective chart review was completed on patients younger than 18 years who underwent MPFLR for recurrent instability after failed nonoperative management over an 8-year period with a minimum 2-year follow-up...

Hege Grindem, Elizabeth Wellsandt, Mathew Failla, Lynn Snyder-Mackler, May Arna Risberg
Background: More than 50% of highly active patients with an anterior cruciate ligament (ACL) injury who choose nonsurgical treatment (active rehabilitation alone) have successful 2-year outcomes and comparable knee function to an uninjured population. Early predictive factors for a successful outcome may aid treatment decision making in this population. Purpose: To identify early predictors of a successful 2-year outcome in those who choose nonsurgical treatment of an ACL injury...

#13
Yusuke Nishio, Eiji Kondo, Jun Onodera, Tomohiro Onodera, Tomonori Yagi, Norimasa Iwasaki, Kazunori Yasuda
Background: Several recent studies have reported that favorable clinical results and a high level of patient satisfaction can generally be obtained with no increased risk of complications after single-bundle anterior cruciate ligament (ACL) reconstruction performed in patients >40 years of age. However, no studies have yet clarified the age-based differences in clinical outcomes after double-bundle reconstruction. Purpose: To compare clinical outcomes after double-bundle ACL reconstruction using hamstring tendon hybrid grafts between patients in 2 different age groups: ≥40 years and <40 years...

#14
Jason A Grieshober, Nima Mehran, Christos Photopolous, Matthew Fishman, Stephen J Lombardo, F Daniel Kharrazi
Background: Vitamin D is believed to play a role in influencing fracture risk and athletic performance. Insufficiency of vitamin D affects an estimated three-quarters of the United States population. Hypovitaminosis D has also been demonstrated to be quite common among professional basketball players in the National Basketball Association (NBA). Purpose: To determine whether a relationship exists between vitamin D levels and fracture risk and athletic performance (as measured by NBA draft status) among elite basketball players...

#15
Karl F Orishimo, Sidse Schwartz-Balle, Timothy F Tyler, Malachy P McHugh, Benjamin B Bedford, Steven J Lee, Stephen J Nicholas
Background: Disproportionate end-range plantar flexion weakness, decreased passive stiffness, and inability to perform a heel rise on a decline after Achilles tendon repair are thought to reflect increased tendon compliance or tendon lengthening. Since this was first noted, we have performed stronger repairs and avoided stretching into dorsiflexion for the first 12 weeks after surgery. Hypothesis: Using stronger repairs and avoiding stretching into dorsiflexion would eliminate end-range plantar flexion weakness and normalize passive stiffness...

Patrick J Denard, Christopher R Adams, Nicole C Fischer, Marina Piepenbrink, Coen A Wijdicks
Background: Historically, tendon-to-bone fixation has relied on knot tying. However, considerable variability exists in knot-tying strength among surgeons. Purpose/Hypothesis: The purpose of this study was to compare the biomechanical properties of knotted and knotless fixation and to evaluate variability among surgeons. The hypothesis was that knotless constructs would be stronger and have less variability as compared with knotted constructs. Study Design: Controlled laboratory study...

Jordan E Johnson, Joshua A Fullmer, Chaseton M Nielsen, Joshua K Johnson, Claude T Moorman
Background: There is an association between throwing activity and glenohumeral internal rotation deficit (GIRD). An 18° to 20° deficit has been adopted as the standard definition of pathological GIRD, but specific findings as to how GIRD relates to an injury are inconsistent. Purpose: To systematically review the literature to clarify the definition of GIRD diagnosis for adolescent and adult overhead athletes and to examine the association between GIRD and an increased risk of injuries in these athletes...

#18
Drew A Lansdown, Gift Ukwuani, Benjamin Kuhns, Joshua D Harris, Shane J Nho
Background: Femoroacetabular impingement (FAI) is responsible for hip pain and dysfunction, and surgical outcomes depend on multiple factors. The presence of mental disorders negatively influences outcomes of multiple orthopaedic conditions, although the impact on FAI surgery is unclear. Hypothesis: The authors hypothesized that a preoperative self-reported history of mental disorders would negatively influence patient-reported outcome measures after FAI surgery...
