Infratuberosity Anterior Closing-Wedge High Tibial Osteotomy for Slope Correction in Anterior Cruciate Ligament-Deficient Knees.

Graft failure after anterior cruciate ligament reconstruction is multifactorial, with increased tibia slope identified as one of the risk factors. Several slope-correcting osteotomies have been proposed to address this in revision surgery, with most of the procedures using a supratuberosity or transtuberosity approach. Although satisfactory results have been presented, severe complications involving the extensor mechanism can occur.

Young or Old Age and Non-White Race Are Associated With Poor Patient-Reported Outcome Measure Response Compliance After Orthopaedic Surgery.

Purpose: To investigate orthopaedic patient compliance with patient-reported outcome measures (PROMs) and identify factors that improve response rates.

Methods: Our search strategy comprised a combination of key words and database-specific subject headings for the concepts of orthopaedic surgical procedures, compliance, and PROMs from several research databases from inception to October 11, 2022. Duplicates were removed.

Suture-Augmented Anterior Cruciate Ligament Repair for Proximal Avulsion or High-Grade Partial Tears Shows Similar Side-to-Side Difference and No Clinical Differences at Two Years Versus Conventional Anterior Cruciate Ligament Reconstruction for Mid-Substance Tears or Poor Anterior Cruciate Ligament Tissue Quality.

Purpose: To compare objective and subjective clinical outcomes between suture-augmented anterior cruciate ligament (ACL) repair (SAACLR) and conventional ACL reconstruction (CACLR) with minimum 2-year follow-up.

Methods: In this nonrandomized, prospective study, 30 patients underwent SAACLR for proximal ACL avulsion or high-grade partial ACL tear (Sherman grade 1 or 2) and 30 patients underwent CACLR for proximal one-third/distal two-thirds junction tears and mid-substance tears (Sherman grade 3 or 4) tear types by 1 surgeon between 2018 and 2020. Failure was defined as ACL reinjury.

Postoperative Rehabilitation of Ulnar Collateral Ligament Reconstruction: A Systematic Review.

The incidence of ulnar collateral ligament injuries has increased over the past few decades with greater participation in overhead throwing sports; however, optimal postoperative management following surgery remains unclear. This systematic review summarizes the latest evidence, on postoperative rehabilitation protocols for patients undergoing ulnar collateral ligament reconstruction (UCLR). Studies published in the English language from the year 2000 to 2019 with a level 1 to 4 grade of evidence and examined rehabilitation protocols following UCLR were eligible for inclusion.

Anterior Cruciate Ligament Repair with Suture Augmentation for Proximal Avulsion Injuries.

Purpose: To assess failure rate, outcomes, and patient satisfaction in patients who underwent anterior cruciate ligament (ACL) repair with suture augmentation for clinical instability and proximal avulsion of the ACL.

Methods: We retrospectively reviewed consecutive suture-augmented ACL repairs performed by a single surgeon between January 2014 and June 2016 for proximal ACL avulsion. Patients were included if they were at least 24 months postoperative from repair surgery.

Treatment of Acute Proximal Anterior Cruciate Ligament Tears-Part 2: The Role of Internal Bracing on Gap Formation and Stabilization of Repair Techniques.

Background: The latest biomechanical studies on some form of internal bracing have shown improved stabilization for anterior cruciate ligament (ACL) repair, but gap formation and load-sharing function have not yet been reported.

Hypothesis: Internal bracing of an adjustable ACL repair construct provides improved stabilization with reduced gap formation and higher residual loading on the ACL.

Study Design: Controlled laboratory study.

Treatment of Acute Proximal Anterior Cruciate Ligament Tears-Part 1: Gap Formation and Stabilization Potential of Repair Techniques.

Background: Recently, there has been a resurgence of interest in primary repair of the anterior cruciate ligament (ACL), with fixation techniques evolving. However, to date, there have been no biomechanical studies comparing fixed to adjustable fixation repair techniques.

Hypothesis: Adjustable ACL repair provides for improved stabilization compared with fixed techniques with respect to both gap formation and residual load-bearing capability.

Conjoined Tendon Transfer for Traumatic Anterior Glenohumeral Instability in Patients With Large Bony Defects and Anterior Capsulolabral Deficiency.

Purpose: To report outcomes of a conjoined tendon transfer procedure in a small case series of young active patients of various activity levels with recurrent traumatic anterior shoulder instability.

Methods: A retrospective chart review identified 10 consecutive patients who underwent conjoined tendon transfer (8 open and 2 arthroscopic) for anterior glenohumeral instability from January 2009 through December 2012. The indications were traumatic anterior shoulder instability with 25% or greater anterior glenoid bone loss, engaging Hill-Sachs lesion, or absent anterior-inferior labral tissue with anterior capsular tissue that did not readily hold sutures or a combination of these deficiencies.

Early Cocking Phase Mechanics and Upper Extremity Surgery Risk in Starting Professional Baseball Pitchers.

Background: Early cocking phase pitching mechanics may affect risk of upper extremity injury requiring surgery in professional baseball players.

Purpose: To assess the occurrence of inverted-W arm positioning and early trunk rotation in Major League Baseball (MLB) pitchers and to determine whether this throwing position is associated with upper extremity injury requiring surgery.

Study Design: Cross-sectional study; Level of evidence, 3.

Effect of distal ulnar collateral ligament tear pattern on contact forces and valgus stability in the posteromedial compartment of the elbow.

Background: It is not known whether the pattern of ulnar collateral ligament (UCL) tear affects elbow biomechanics.

Hypothesis: There will be a significant change in elbow biomechanics with 50% proximal but not 50% distal simulated rupture of the UCL.

Study Design: Controlled laboratory study.

Anterior shoulder instability with Bristow procedure versus conjoined tendon transfer alone in a simple soft-tissue model.

Purpose: We compared the Bristow procedure with a conjoined tendon transfer to investigate the role of the sling alone in restoring anterior translation in a simple soft-tissue instability model without bony defects.

Methods: Ten matched cadaveric shoulder pairs were randomly assigned to receive a Bristow procedure or a conjoined tendon transfer alone. Specimens were tested in a simple soft-tissue model with low load simulating anterior translation of the glenohumeral joint.

Epidemiology of lacrosse injuries in high school-aged girls and boys: a 3-year prospective study.

Objective: To report the types, mechanisms, and circumstances of lacrosse injuries incurred by high school-aged girls and boys during organized interscholastic and summer camp games.

Study Design: Descriptive epidemiology study.

Methods: For 3 years, the authors gathered data on girls' and boys' lacrosse injuries for 359 040 high school and 28 318 summer camp athletic exposures using a lacrosse-specific computerized injury surveillance system.
