#41
JOURNAL ARTICLE
Yurou Chen, Jia Li, Haitao Yang, Fajin Lv, Bo Sheng, Furong Lv
BACKGROUND: Considering that patellofemoral pain (PFP) is related to dynamic factors, dynamic extension on 4-dimensional computed tomography (4-DCT) may better reflect the influence of muscles and surrounding soft tissue than static extension. PURPOSE: To compare the characteristics of patellofemoral alignment between the static and dynamic knee extension position in patients with PFP and controls via 4-DCT. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

BACKGROUND: The gluteus minimus (GMin) and gluteus medius (GMed) are important dynamic stabilizers of the hip, but quantitative data on their biomechanical roles in stabilizing the hip are currently lacking. PURPOSE: To (1) establish a reproducible biomechanical cadaveric model of the hip abductor complex and (2) characterize the effects of loading the GMin and GMed on extraneous femoral rotation and distraction. STUDY DESIGN: Controlled laboratory study...

BACKGROUND: While concomitant rotator cuff and inferior labral tears are relatively uncommon in young civilians, military populations represent a unique opportunity to study this injury pattern. PURPOSE: To (1) evaluate the long-term outcomes after combined arthroscopic rotator cuff and inferior labral repair in military patients <40 years and (2) compare functional outcomes with those after isolated arthroscopic rotator cuff repair. STUDY DESIGN: Cohort study; Level of evidence, 3...

BACKGROUND: One proposed mechanism of rotator cuff disease is scapular motion impairments contributing to rotator cuff compression and subsequent degeneration. PURPOSE: To model the effects of scapular angular deviations on rotator cuff tendon proximity for subacromial and internal mechanical impingement risk during scapular plane abduction. STUDY DESIGN: Descriptive laboratory study. METHODS: Three-dimensional bone models were reconstructed from computed tomography scans obtained from 10 asymptomatic subjects and 9 symptomatic subjects with a clinical presentation of impingement syndrome...

#45
JOURNAL ARTICLE
Nam-Hong Choi, Bong-Seok Yang, Dong-Min Lee, Choong-Ryul Lee
BACKGROUND: In the setting of anterior cruciate ligament (ACL) injury, lateral meniscus posterior root tears (LMPRTs) are less readily diagnosed on preoperative magnetic resonance imaging (MRI). Therefore, to predict LMPRTs in ACL injuries, it is necessary to understand the risk factors associated with them. PURPOSE/HYPOTHESIS: The purpose of this study was to investigate the association of lateral femoral condylar ratio (LFCR) with LMPRTs in ACL injuries. It was hypothesized that an increased LFCR would be associated with LMPRTs in noncontact ACL injuries...

BACKGROUND: Anterolateral ligament reconstruction (ALLR) or lateral extra-articular tenodesis (LET) is being used more frequently in conjunction with anterior cruciate ligament reconstruction (ACLR). However, the knee flexion angle at which fixation of ALLR or LET is performed during the procedure is quite variable based on existing technique descriptions. PURPOSE/HYPOTHESIS: The purpose of this study was to identify whether flexion angle at the time of ALLR/LET fixation affected postoperative outcomes in a clinical population...

BACKGROUND: Reduced graft failure rates have been reported after anterior cruciate ligament (ACL) reconstruction combined with anterolateral complex (ALC) augmentation. However, the preoperative diagnosis of concomitant ALC injury remains a clinical challenge. PURPOSE: To identify the altered rotational tibiofemoral position on magnetic resonance imaging (MRI) in ACL-injured patients with concomitant ALC injury.

JOURNAL ARTICLE
Peng Chen, Ling Wang, Shiyu Dong, Yue Ding, Huiwu Zuo, Shaohui Jia, Guanglan Wang, Can Chen, Cheng Zheng
BACKGROUND: A limb symmetry index (LSI) of >90% for single-leg horizontal hop distance is recommended as a cutoff point for safe return to sports after anterior cruciate ligament reconstruction (ACLR). Despite achieving this threshold, abnormal lower limb biomechanics continue to persist in athletes after ACLR. Symmetry in single-leg vertical hop height appears to be more difficult to achieve and can be a better representation of knee function than single-leg horizontal hop distance...

BACKGROUND: Previous studies have attempted to determine if certain risk factors can predict the occurrence of a lateral ankle sprain (LAS) in female soccer players. Unfortunately, there is limited evidence with regard to risk factors associated with an LAS in female soccer players. PURPOSE: To identify intrinsic risk factors for an LAS among young female soccer players. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: Participants were 161 young female soccer players in Japan who were evaluated for LAS risk factors during a preseason medical assessment...

BACKGROUND: Confusion persists regarding the ideal dosage of platelet-rich plasma (PRP) injection for knee osteoarthritis (OA). PURPOSE/HYPOTHESIS: The purpose of the study was to compare the efficacy of 2 different single-injection PRP dosages in patients with early knee OA-a conventional 4 mL dose and a superdose of 8 mL. It was hypothesized that 8 mL of PRP would be superior to 4 mL of PRP in this patient population. STUDY DESIGN: Randomized clinical trial; Level of evidence, 1...

BACKGROUND: Prevention of pitching-related elbow pain in youth baseball players is important. Overhead pitching involves a whole-body motion, including head-neck rotation. A limited range of motion of head-neck rotation may cause inefficient pitching motion; however, this association is unclear. PURPOSE: To determine whether the range of motion of head-neck rotation is associated with the history of pitching-related elbow pain in youth baseball players. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

REVIEW
Phillip B Wyatt, Tiffany D Ho, Haleigh M Hopper, James R Satalich, Conor N O'Neill, John Cyrus, Alexander R Vap, Robert O'Connell
BACKGROUND: Traditionally, postoperative rehabilitation protocols after proximal hamstring repair (PHR) for avulsion of the proximal hamstring tendon from its ischial insertion recommend bracing the hip and/or knee to protect the fixation. However, because of the cumbersome nature of these orthoses, recent studies have investigated outcomes in patients with postoperative protocols that do not include any form of postoperative bracing. PURPOSE: To synthesize the current body of evidence concerning bracing versus nonbracing postoperative management of PHR...

#59
JOURNAL ARTICLE
Mustafa S Rashid, Saho Tsuchiya, Kristie D More, Justin LeBlanc, Aaron J Bois, Cory A Kwong, Ian K Y Lo
BACKGROUND: Failure after isolated Bankart repair has led surgeons to consider when to address the Hill-Sachs lesion, which is thought to be a contributor to recurrent instability. One approach utilizes the glenoid track concept to determine whether a Hill-Sachs lesion is classified as "off-track," suggesting that the addition of a remplissage procedure may aid stability. However, the accuracy and reliability of using this approach require validation using an appropriate reference. PURPOSE: To determine the accuracy and reliability of using the glenoid track concept against dynamic arthroscopic assessment of Hill-Sachs lesion engagement...

BACKGROUND: Few studies have reported clinical outcomes and tendon healing rates after arthroscopic isolated subscapularis (SSC) repair (AISR). PURPOSE/HYPOTHESIS: The primary purpose of this study was to evaluate clinical outcomes and tendon healing after AISR. It was hypothesized that AISR would result in satisfactory clinical outcomes along with a high rate of tendon healing at the midterm follow-up. The secondary purpose was to assess the influence of tear size and muscle atrophy on SSC tendon healing and patient-reported outcomes...
