Performance of 5-Strand Hamstring Autograft Anterior Cruciate Ligament Reconstruction in the STABILITY Study: A Subgroup Analysis.

Background: Anterior cruciate ligament (ACL) reconstructions (ACLRs) with graft diameters <8mm have been shown to have higher revision rates. The 5-strand (5S) hamstring autograft configuration is a proposed option to increase graft diameter.

Purpose: To investigate the differences in clinical outcomes between 4-strand (4S) and 5S hamstring autografts for ACLR in patients who underwent ACLR alone or concomitantly with a lateral extra-articular tenodesis (LET) procedure.

Predictors of Graft Failure in Young Active Patients Undergoing Hamstring Autograft Anterior Cruciate Ligament Reconstruction With or Without a Lateral Extra-articular Tenodesis: The Stability Experience.

Background: Anterior cruciate ligament (ACL) reconstruction (ACLR) has higher failure rates in young active patients returning to sports as compared with older, less active individuals. Augmentation of ACLR with an anterolateral procedure has been shown to reduce failure rates; however, indications for this procedure have yet to be clearly defined.

Purpose/hypothesis: The purpose of this study was to identify predictors of ACL graft failure in high-risk patients and determine key indications for when hamstring ACLR should be augmented by a lateral extra-articular tenodesis (LET).

Association of Ligamentous Laxity, Male Sex, Chronicity, Meniscal Injury, and Posterior Tibial Slope With a High-Grade Preoperative Pivot Shift: A Post Hoc Analysis of the STABILITY Study.

Background: A spectrum of anterolateral rotatory laxity exists in anterior cruciate ligament (ACL)-injured knees. Understanding of the factors contributing to a high-grade pivot shift continues to be refined.

Purpose: To investigate factors associated with a high-grade preoperative pivot shift and to evaluate the relationship between this condition and baseline patient-reported outcome measures (PROMs).

Lateral Extra-articular Tenodesis Reduces Failure of Hamstring Tendon Autograft Anterior Cruciate Ligament Reconstruction: 2-Year Outcomes From the STABILITY Study Randomized Clinical Trial.

Background: Persistent anterolateral rotatory laxity after anterior cruciate ligament (ACL) reconstruction (ACLR) has been correlated with poor clinical outcomes and graft failure.

Hypothesis: We hypothesized that a single-bundle, hamstring ACLR in combination with a lateral extra-articular tenodesis (LET) would reduce the risk of ACLR failure in young, active individuals.

Study Design: Randomized controlled trial; Level of evidence, 1.

Editorial Commentary: Yet Another Way to Measure Hip Surgery Patient Outcomes: Will This Ever End?

The Hip Preservation Surgery Expectations Survey (HPSES) developed by Mancuso et al. is an attempt to better predict outcome and/or discriminate between patients who are candidates for hip preservation surgery. The authors have ensured that patient input was paramount in the development of the survey.

The use of magnetic resonance imaging in acute knee injuries can be reduced by non-physician expert clinics.

Introduction: The routine use of magnetic resonance imaging (MRI) for the assessment of acute knee injuries is controversial. The goal of this study is to present an audit of patients seen in a dedicated Acute Knee Injury Clinic (AKIC) to determine the frequency and appropriateness of MRI utilization.

Methods: A retrospective review identified all patients who had an MRI and a randomly selected control group without MRI.

Intra-abdominal fluid extravasation during hip arthroscopy: a survey of the MAHORN group.

Purpose: The purpose of this study was to survey experts in the field of hip arthroscopy from the Multicenter Arthroscopy of the Hip Outcomes Research Network (MAHORN) group to determine the frequency of symptomatic intra-abdominal fluid extravasation (IAFE) after arthroscopic hip procedures, identify potential risk factors, and develop preventative measures and treatment strategies in the event of symptomatic IAFE.

Methods: A survey was sent to all members of the MAHORN group. Surveys collected data on general hip arthroscopy settings, including pump pressure and frequency of different hip arthroscopies performed, as well as details on cases of symptomatic IAFE.

Managing anterior cruciate ligament deficiency in the skeletally immature individual: a systematic review of the literature.

Objective: To perform a systematic review of the literature to answer whether early ACL reconstruction for a skeletally immature individuals result in improved outcome compared with nonsurgical treatment or delaying the reconstruction until skeletal maturity in the pediatric athlete.

Data Sources: Articles were restricted to the English language, and 6 databases were searched (MEDLINE, CINAHL, EMBASE, ACP Journal Club, Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews). The following keywords were used: anterior cruciate ligament, ACL, child, immature, pediatric, pediatric, and young.
