Decision-making in borderline hip dysplasia and concomitant femoracetabular impingement syndrome: using a discrete choice experiment to explore patient preferences.

Decision-making regarding surgical treatment of patients showing radiographic evidence of femoroacetabular impingement syndrome (FAIS) in the setting of borderline hip dysplasia (BHD) remains a challenge as there is no consensus on treatment in current literature. When medical evidence is unclear, understanding patient preferences becomes particularly important in deciding the optimal treatment for each patient. The purpose of this study was to measure the patient-determined importance of factors surrounding surgical treatment of FAIS in BHD.

Research as an Early-Career Sports Surgeon: Keys to Success.

Research as an early-career surgeon is challenging. The resources that you had as a trainee are not established yet and it can be difficult to balance while learning to be an effective clinician and surgeon. Starting early, however, before clinical and leadership responsibilities build up is a key to developing a successful research program.

Update on elbow arthroplasties with emphasis on imaging.

Elbow arthroplasty is increasing in popularity and can be used to treat many conditions, such as trauma, primary and secondary osteoarthritis, inflammatory arthritis, and osteonecrosis. Total elbow arthroplasty (TEA) is reserved for patients with severe symptoms refractory to more conservative management. In addition to TEA, hemi-arthroplasty, interposition arthroplasty, and resection arthroplasty also play roles in the management of elbow pain.

High-resolution ultrasound and MRI in the evaluation of pectoralis major injuries.

The pectoralis major muscle is the largest muscle of the anterior chest wall. The primary function of the muscle is to adduct and internally rotate the arm at the shoulder. The pectoralis major muscle is broken down into two main components or "heads" based upon muscle fiber origin: clavicular and sternal.

Nonoperative Management, Repair, or Reconstruction of the Medial Collateral Ligament in Combined Anterior Cruciate and Medial Collateral Ligament Injuries-Which Is Best? A Systematic Review and Meta-analysis.

Background: Combined injury of the anterior cruciate ligament (ACL) and the medial collateral ligament (MCL) is a common injury pattern and accounts for 20% of all ligamentous knee injuries. Despite advancements in surgical technique, there is no up-to-date consensus regarding the superiority of nonoperative versus operative management in higher-grade MCL tears of combined ACL-MCL injuries.

Purpose: To interpret recent literature on treatment options and to provide an updated evidence-based approach for management of combined ACL-MCL knee injuries.

Long-term National Trends of Arthroscopic Meniscal Repair and Debridement.

Background: Optimal treatment of meniscal pathology continues to evolve in orthopaedic surgery, with a growing understanding of which patients benefit from which procedure and which patients might be best treated nonsurgically. In 2002, Moseley et al found no difference between arthroscopic procedures, including meniscal debridement and sham surgery, in patients with osteoarthritis of the knee. This called into question the role of routine arthroscopic debridement in these patients.

Is Diagnostic Arthroscopy at the Time of Medial Patellofemoral Ligament Reconstruction Necessary?

Background: Although medial patellofemoral ligament (MPFL) reconstruction is well described for patellar instability, the utility of arthroscopy at the time of stabilization has not been fully defined.

Purpose: To determine whether diagnostic arthroscopy in conjunction with MPFL reconstruction is associated with improvement in functional outcome, pain, and stability or a decrease in perioperative complications.

Study Design: Cohort study; Level of evidence, 3.

Well Leg Compartment Syndrome after Contralateral Femoral Neck ORIF.

The authors present a case of WLCS after femoral neck fracture fixation. While this is a rare complication, a high index of suspicion should exist. Surgeons should use well leg holders with caution and limit utilization time.

Irreducible Knee Dislocation Associated With a Tertiary Gastrocnemius Head: A Case Report.

Case: A 43-year-old man suffered an irreducible posterolateral knee dislocation while snowboarding with associated tears of the anterior cruciate, posterior cruciate, medial collateral, and posterolateral corner ligaments. Two closed reduction attempts failed, and magnetic resonance imaging revealed incarcerated soft tissue from a tertiary gastrocnemius muscle head. The patient underwent open reduction and repair/reconstruction of his multiligamentous knee injury.

Operative Versus Nonoperative Management Of Traumatic Arthrotomies from Civilian Gunshot Wounds.

Background: Although the rate of non-fatal gunshot wounds (GSW) has increased, few studies have compared the effectiveness of operative and nonoperative treatment with specific focus on infection. We compared the risk of septic arthritis in patients with traumatic arthrotomies caused by GSW treated operatively with irrigation and debridement versus nonoperatively with antibiotics and wound care.

Methods: From 2009 to 2016, 46 patients at our institution sustained traumatic arthrotomies from low-velocity GSW with at least 90-day follow-up.

The influence of intrinsic and extrinsic factors on immune system aging.

Sex and age-matched wild-type and TCR transgenic mice were infected with cytomegalovirus (CMV) at 6 months of age and followed for 12 additional months to examine aging of the immune system. It was found that viral infection of C57Bl/6 mice resulted in accelerated aging of the immune system as shown by a loss of CD8(+)28(+) cells and an accumulation of KLRG1(+) T cells. CMV infection of OT-1 transgenic mice had no influence on immune aging of these mice which nonetheless demonstrated an accumulation of CD8(+)28(-) and KLRG1(+) T cells with time.

Effects of a synthetic factor Xa inhibitor (JTV-803) on various laboratory tests.

Synthetic direct inhibitors of factor Xa are capable of prolonging the global anticoagulant assay times in a concentration-dependent fashion. The relative degree of thrombin generation inhibition at an equivalent prolongation is not similar to the results observed with heparins and oral anticoagulant drugs. In addition, the direct factor Xa inhibitors prolong the Russell's viper venom test (RWT) and Heptest clotting times.
