Clinical Outcomes of a Novel Hybrid Transtibial Technique for Femoral Tunnel Drilling in Anterior Cruciate Ligament Reconstruction: A Large Single-Center Case Series With a Minimum 2-Year Follow-up.

Background: A novel hybrid transtibial (HTT) approach to femoral tunnel drilling in anterior cruciate ligament reconstruction (ACLR) has been developed that circumvents the need for knee hyperflexion and orients the graft in the most anatomic position without sacrificing the tunnel length or aperture.

Hypothesis: Patients who underwent ACLR utilizing the HTT technique would achieve excellent patient-reported outcome scores and experience low rates of graft failure and reoperations.

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

Purpose: Little is known about the optimal analgesia regimen after HTO. Thus, this study systematically reviewed the literature on clinical and patient-reported outcomes of pain management strategies for patients after HTO.

Methods: A comprehensive search of the PubMed, Cochrane CENTRAL, and CINAHL databases was conducted from inception through September 2023.

The Effect of Lower Limb Alignment on Tibiofemoral Joint Contact Biomechanics after Medial Meniscus Posterior Root Repair: A Finite-Element Analysis.

Introduction: The purpose of this study was to determine how variations in lower limb alignment affect tibiofemoral joint contact biomechanics in the setting of medial meniscus posterior root tear (MMPRT) and associated root repair.

Methods: A finite-element model of an intact knee joint was developed. Limb alignments ranging from 4° valgus to 8° varus were simulated under a 1,000 N compression load applied to the femoral head.

Impacts of the Early COVID-19 Pandemic on Depressive Symptoms and Mental Health Among Student-Athletes.

Objective: Social distancing protocols due to the COVID-19 pandemic resulted in premature ending of athletic seasons and cancellation of upcoming seasons, placing significant stress on young athletes. Inability to play or forced early retirement has significant consequences on athlete's mental health, as demonstrated by an extensive body of injury literature. We hypothesize that premature suspension and cancellation of athletic events due to the COVID-19 pandemic leads to higher incidence of depressive symptoms among high-school and collegiate athletes.

Early Postoperative Complications and Associated Variables After Tibial Tubercle Osteotomy: A 15-Year Experience From a Single Academic Institution.

Background: Tibial tubercle osteotomy (TTO) is a well-established surgical treatment option for patients with patellofemoral disorders.

Purpose: To determine the rate of early (≤90 day) postoperative complications after TTO and variables related to postoperative complications.

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

Early Postoperative Complications and Associated Variables After High Tibial Osteotomy and Distal Femoral Osteotomy: A 15-Year Experience From a Single Academic Institution.

Background: High tibial osteotomy (HTO) and distal femoral osteotomy (DFO) are well-recognized treatments to address varus and valgus malalignment, respectively, in the setting of symptomatic unicompartmental arthritis of the tibiofemoral joint. The existing literature is limited in its ability to characterize complications after HTO or DFO procedures.

Purpose: The objective of this study was to determine the rate of early (≤90 days) postoperative complications and associated variables from the 15-year experience of a single academic institution.

Trends in Patient-Reported Outcomes After Anterior Cruciate Ligament Reconstruction: A Systematic Review.

Background: Despite the prevalence of patient-reported outcomes (PROs) to evaluate results after anterior cruciate ligament (ACL) reconstruction, there exists little standardization in how these metrics are reported, which can make wider comparisons difficult.

Purpose: To systematically review the literature on ACL reconstruction and report on the variability and temporal trends in PRO utilization.

Study Design: Systematic review.

Inconsistencies in reporting risk factors for ulnar collateral ligament reconstruction failure: a systematic review.

Background: When return to sport (RTS) at a competitive level is desired, treatment of injury to the ulnar collateral ligament (UCL) frequently involves surgical reconstruction. Although RTS rates between 66% and 98% have been reported, there remains a paucity of comparative clinical studies, with far fewer reporting statistically significant risk factors for reconstruction failure. The goal of this study was to perform a systematic review of the literature to demonstrate the variety and inconsistency with which risk factors associated with reconstruction failure are reported.

Clinical Outcomes After ACL Reconstruction in Soccer (Football, Futbol) Players: A Systematic Review and Meta-Analysis.

Context: The risk factors for anterior cruciate ligament (ACL) tear for athletes participating in pivoting sports includes young age and female sex. A previous meta-analysis has reported a reinjury rate of 15% after ACL reconstruction (ACLR) for athletes across all sports. To the best of the authors' knowledge, this is the first systematic review and meta-analysis of available literature reporting outcomes after ACLR in soccer players.

Onlay Versus Inlay Biceps Tenodesis for Long Head of Biceps Tendinopathy: A Systematic Review and Meta-analysis.

Introduction: Proximal biceps tenodesis is a common surgical treatment of tendinosis of the long head of the biceps tendon. Two of the most common techniques incorporate onlay and inlay fixation methods, which can be done arthroscopically or open and in a variety of anatomic locations. The purpose of this meta-analysis was to compare the clinical outcomes between onlay versus inlay humeral fixation for biceps tenodesis for long head of the biceps tendon pathology.

Purpose: The purpose of this finite element analysis was to compare femoral tunnel length; anterior cruciate ligament reconstruction graft bending angle; and peak graft stress, contact force, and contact area created by the transtibial, anteromedial portal (AMP), and hybrid transtibial techniques.

Methods: Finite element analysis modeling was used to examine anterior cruciate ligament reconstruction models based on transtibial, AMP, and hybrid transtibial femoral tunnel drilling techniques. An evaluation of femoral tunnel length, graft bending angle, peak graft stress, contact force, and contact area was done in comparison of these techniques.

Isolated Osteochondral Autograft Versus Allograft Transplantation for the Treatment of Symptomatic Cartilage Lesions of the Knee: A Systematic Review and Meta-analysis.

Background: Focal cartilage lesions of the knee remain a difficult entity to treat. Current treatment options include arthroscopic debridement, microfracture, autograft or allograft osteochondral transplantation, and cell-based therapies such as autologous chondrocyte transplantation. Osteochondral transplantation techniques restore the normal topography of the condyles and provide mature hyaline cartilage in a single-stage procedure.

Background: The purpose of this study was to compare outcomes of patients who underwent posterior labral repair with and without concomitant glenohumeral chondral pathology.

Methods: A retrospective review was performed on patients aged ≥18 years who underwent primary posterior labral repair over 5 years. Charts were reviewed to determine the presence and location of high-grade (Outerbridge grade III or IV) pathology.

Influence of graft type on sagittal plane knee biomechanics during stair ambulation following anterior cruciate ligament reconstruction.

Background: Both graft type and surgical technique for anterior cruciate ligament reconstruction can affect knee biomechanics. Several studies reported the influence of graft type, but few have controlled the surgical technique and fully investigated stair ambulation. This study aimed to compare knee biomechanics during stair ambulation between patients treated with hamstring tendon graft and those treated with patellar tendon graft when anterior medial portal technique was used to drill femoral tunnel.

A Hybrid Transtibial Technique Combines the Advantages of Anteromedial Portal and Transtibial Approaches: A Prospective Randomized Controlled Trial.

Background: The anteromedial (AM) portal and transtibial (TT) approaches are 2 common anterior cruciate ligament (ACL) femoral tunnel drilling techniques, each with unique benefits and disadvantages. A hybrid TT (HTT) technique using medial portal guidance of a flexible TT guide wire has recently been described that may combine the strengths of both the AM portal and the TT approaches.

Hypothesis: The HTT technique will achieve anatomic femoral tunnel apertures similar to the AM portal technique, with improved femoral tunnel length and orientation.
