The Weekend Warrior: Common Shoulder and Elbow Injuries in the Recreational Athlete.

"Weekend warriors" are recreational athletes who compress their physical activity into 1-2 weekly exercise sessions. These individuals are generally older than the conventionally discussed athlete, and can live otherwise sedentary lifestyles that contribute to limited opportunities for regular exercise. The combination of high-energy physical activity with relative deconditioning, as well as older age and a potential history of competitive athletic play, can predispose these weekend warriors to a plethora of sports injuries.

A preliminary assessment of intervertebral disc health and pathoanatomy changes observed two years following anterior vertebral body tethering.

Purpose: Vertebral body tethering (VBT) has been reported as a safe and effective non-fusion surgical technique for the treatment of adolescent idiopathic scoliosis, but the postoperative health of the bone and soft tissues of the spine following instrumentation remains unknown. We aimed to evaluate pathoanatomy and degenerative changes of the spine in adolescent idiopathic scoliosis patients both prior to and two years following VBT.

Methods: We prospectively enrolled nine patients who underwent VBT for the treatment of progressive adolescent idiopathic scoliosis.

Bacterial DNA screening to characterize surgical site infection risk in orthopaedic patients.

Purpose: To provide an initial characterization of relevant bacterial DNA profiles for patients undergoing closed-fracture fixation or total joint arthroplasties.

Patients And Methods: Swabs were collected and analyzed using Polymerase Chain Reaction from adult patients undergoing closed-fracture fixation or total shoulder, knee, or hip arthroplasties.

Results: Bacterial DNA profiles varied across the different orthopaedic patient populations, and produced uncharacteristic profile shifts with direct relevance to each clinical infection.

What Are the Risk Factors for an Upper Extremity Deep Venous Thrombosis After Orthopaedic Irrigation and Debridement and Peripherally Inserted Central Catheter Placement?

Background: Peripherally inserted central catheter (PICC) placement is necessary for delivery of intravenous (IV) antibiotics to treat bone and soft tissue infections. Upper extremity deep venous thrombosis (DVT) after PICC placement is a complication with unknown incidence in the orthopaedic literature. The major objectives of this study are Identifying the rate of upper extremity PICC-associated DVTs after orthopaedic procedures;Which orthopaedic subspecialties are most likely to encounter an upper extremity PICC-associated DVT?What surgeries or medical comorbidities are risk factors for upper extremity PICC-associated DVTs?Does type of DVT chemoprophylaxis decrease the risk of an upper extremity PICC-associated DVT?

Methods: A retrospective review of electronic medical records (EMR) was performed to include all patients undergoing irrigation and debridement (I&D) for treatment of orthopaedic surgery-related infections over a 10-year period.

Bone, Biomarker, Body Composition, and Performance Responses to 8 Weeks of Reserve Officers' Training Corps Training.

Context: Military personnel engage in vigorous exercise, often resulting in higher bone mineral density; however, leg bone injuries occur frequently in this population. Predictors of change in tibial bone quality and strength need to be characterized in this high-risk population.

Objectives: To examine the effects of an 8-week military training intervention on total body and site-specific bone density and tibial bone quality, serum biomarkers (parathyroid hormone and sclerostin), body composition, and physical performance and to investigate which outcome variables (biomarkers, body composition, and physical performance) predict estimated tibial bone strength in college-aged Reserve Officers' Training Corps (ROTC) participants.

Tobacco Use Is Associated with More Severe Adverse Outcomes Than Morbid Obesity after Aseptic Revision TKA.

The association of morbid obesity with increased revision total knee arthroplasty (rTKA) complications is potentially confounded by concurrent risk factors. This study was performed to evaluate whether morbid obesity was more strongly associated with adverse aseptic rTKA outcomes than diabetes or tobacco use history-when present as a solitary major risk factor. Demographic characteristics, surgical indications, and adverse outcomes (reoperation, revision, infection, and amputation) were compared between 270 index aseptic rTKA performed for patients with morbid obesity ( = 73), diabetes ( = 72), or tobacco use ( = 125) and 239 "healthy" controls without these risk factors at a mean 75.

An Arthroscopic-Assisted Radial Meniscal Tear Repair Using Reinforced Suture Tape Rebars and Suture Tapes.

A radial tear of the meniscus can lead to significant loss of meniscus function, resulting in deleterious cartilage changes. Repair of radial meniscus tears has several challenges, including suture pull-out, which can reduce healing success. We present an arthroscopic repair technique in a complete radial lateral meniscus tear using vertical reinforced bars (rebar) of suture tapes to reduce suture pull-out and approximate the radial tear.

Perspectives of patients with chronic pain about a pain science education video.

Patient satisfaction following total knee arthroplasty using restricted kinematic alignment.

Aims: Alternative alignment concepts, including kinematic and restricted kinematic, have been introduced to help improve clinical outcomes following total knee arthroplasty (TKA). The purpose of this study was to evaluate the clinical results, along with patient satisfaction, following TKA using the concept of restricted kinematic alignment.

Methods: A total of 121 consecutive TKAs performed between 11 February 2018 to 11 June 2019 with preoperative varus deformity were reviewed at minimum one-year follow-up.

Optimal Prosthesis Sizing for Radial Head Arthroplasty: A Review of Current Evidence and Guidelines.

»: Radial head arthroplasty is a viable surgical option when a radial head fracture cannot be reconstructed. Radial head arthroplasty provides a load-bearing articular structure against the capitellum in unstable fractured elbows.

»: Studies have emphasized the importance of choosing the correct implant size to replicate the native radial head anatomy, citing various consequences of improperly sized radial head prostheses.

Histologic evidence for a humoral immune response in synovitis associated with cranial cruciate ligament disease in dogs.

Animals: Thirty client-owned dogs.

Anatomy and Biomechanics of the Posterior Cruciate Ligament.

Posterior cruciate ligament (PCL) injuries are often encountered in the setting of other knee pathology and sometimes in isolation. A thorough understanding of the native PCL anatomy is crucial in the successful treatment of these injuries. The PCL consists of two independent bundles that function in a codominant relationship to perform the primary role of resisting posterior tibial translation relative to the femur.

Return to Sport After Large Single-Surface, Multisurface, or Bipolar Osteochondral Allograft Transplantation in the Knee Using Shell Grafts.

Background: Return to sport (RTS) after osteochondral allograft (OCA) transplantation for large unipolar femoral condyle defects has been consistent, but many athletes are affected by more severe lesions.

Purpose: To examine outcomes for athletes who have undergone large single-surface, multisurface, or bipolar shell OCA transplantation in the knee.

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

Return to Sport After ACL Reconstruction With a BTB Versus Hamstring Tendon Autograft: A Systematic Review and Meta-analysis.

Background: Anterior cruciate ligament (ACL) tears are debilitating injuries frequently suffered by athletes. ACL reconstruction is indicated to restore knee stability and allow patients to return to prior levels of athletic performance. While existing literature suggests that patient-reported outcomes are similar between bone-patellar tendon-bone (BTB) and hamstring tendon (HT) autografts, there is less information comparing return-to-sport (RTS) rates between the 2 graft types.

Outcomes and Complications After Primary Arthroscopic Suprapectoral Versus Open Subpectoral Biceps Tenodesis for Superior Labral Anterior-Posterior Tears or Biceps Abnormalities: A Systematic Review and Meta-analysis.

Background: Biceps tenodesis is a surgical treatment for both superior labral anterior-posterior (SLAP) tears and long head of the biceps tendon (LHBT) abnormalities. Biceps tenodesis can be performed either above or below the pectoralis major tendon with arthroscopic or open techniques.

Purpose: To analyze the outcomes and complications comparing primary arthroscopic suprapectoral versus open subpectoral biceps tenodesis for either SLAP tears or LHBT disorders.

Expanding the horizons of clinical applications of proximal humerus locking plates in the lower extremities: A technical note.

Pre-contoured anatomical locking plates were designed to address the clinical need of fixing small epiphyseal segments with a larger number of screws. Those plates match the contour and shape of a variety of bones allowing for optimal buttress properties. The aim of this manuscript is to highlight the benefits of applying proximal humerus locking plates in the fixation of lower extremity bones.

Bone infection represents a serious complication of orthopedic surgery and Staphylococcus aureus is the most common pathogen. To improve the understanding of host-pathogen interaction, we developed a biospecimen registry (AO Trauma CPP Bone Infection Registry) to collect clinical data, bacterial isolates, and serum from patients with S. aureus bone infection.

Diabetic Pilon Factures: Are They as Bad as We Think?

Objective: To identify how diabetes impacts the risk of complications requiring further surgery (deep surgical site infection, nonunion, amputation, and arthrodesis) after pilon fracture fixation.

Design: Retrospective cohort study.

Setting: Level 1 academic trauma center.

Unicompartmental bipolar osteochondral and meniscal allograft transplantation is effective for treatment of medial compartment gonarthrosis in a canine model.

Osteochondral allograft (OCA) transplantation can restore large articular defects in the knee. Bipolar OCA transplantations for partial and whole joint resurfacing often have less favorable results than single-surface transplants. This study was designed to use a large animal model to test the hypothesis that unicompartmental bipolar osteochondral and meniscal allograft transplantation (BioJoint) would be as or more effective for treatment of medial compartment osteoarthritis (OA) compared to standard-of-care nonoperative treatment.
