Does Medicaid Insurance Confer Adequate Access to Adult Orthopaedic Care in the Era of the Patient Protection and Affordable Care Act?

Joseph T. Labrum BA, Taylor Paziuk BS, Theresa C. Rihn BS, JD, Alan S. Hilibrand MD, Alexander R. Vaccaro MD, PhD, MBA, Mitchell G. Maltenfort PhD, Jeffrey A. Rihn MD

A current appraisal of access to orthopaedic care for the adult patient receiving Medicaid is important, since Medicaid expansion was written into law by the Patient Protection and Affordable Care Act (PPACA).

Does the Utilization of Allograft Tissue in Medial Patellofemoral Ligament Reconstruction in Pediatric and Adolescent Patients Restore Patellar Stability?

Eric Hohn MD, Nirav K. Pandya MD

Medial patellofemoral ligament (MPFL) reconstruction is one of several surgical procedures used to treat patellofemoral instability. Use of allograft tissue can preserve autogenous tissue and may be preferable in patients with connective tissue disorders or ligamentous laxity. Although there are successful reports in adults, it is unclear if the use of allograft tissue in MPFL reconstruction can restore patellofemoral stability in children and adolescents.

Osteochondritis Dissecans Lesions in Family Members: Does a Positive Family History Impact Phenotypic Potency?

Alex L. Gornitzky MD, R. Justin Mistovich MD, Brittany Atuahuene BA, Eileen P. Storey BA, Theodore J. Ganley MD

Although repetitive microtrauma and athletic overuse patterns are most commonly associated with osteochondritis dissecans (OCD), recent studies have identified a potential genetic predisposition for OCD. Several case series have documented family pedigrees that support autosomal-dominant inheritance, but the families in these studies were all selected as a result of unique histories that may not accurately represent OCD inheritance patterns at large. Because there has been little investigation beyond these case reports, we aimed to describe a broader, more representative pattern of OCD inheritance applicable to all affected patients.

Anterolateral Ligament of the Knee Shows Variable Anatomy in Pediatric Specimens

Kevin G. Shea MD, Matthew D. Milewski MD, Peter C. Cannamela BS, Theodore J. Ganley MD, Peter D. Fabricant MD, Elizabeth B. Terhune BS, Alexandra C. Styhl BA, Allen F. Anderson MD, John D. Polousky MD

Anterior cruciate ligament (ACL) reconstruction failure rates are highest in youth athletes. The role of the anterolateral ligament in rotational knee stability is of increasing interest, and several centers are exploring combined ACL and anterolateral ligament reconstruction for these young patients. Literature on the anterolateral ligament of the knee is sparse in regard to the pediatric population. A single study on specimens younger than age 5 years demonstrated the presence of the anterolateral ligament in only one of eight specimens; therefore, much about the prevalence and anatomy of the anterolateral ligament in pediatric specimens remains unknown.

What Influence Does Progression of a Nonhealing Rotator Cuff Tear Have on Shoulder Pain and Function?

Yoon Sang Jeon MD, Rag Gyu Kim MD, Sang-Jin Shin MD

There have been numerous reports of clinical outcomes associated with tendon healing after repair that suggest a nonhealed tendon has a negative effect on postoperative clinical outcomes. However, to our knowledge, there has been no report on the relationship between tear size progression of nonhealed tendons and clinical outcomes.

Does the Critical Shoulder Angle Correlate With Rotator Cuff Tear Progression?

Peter N. Chalmers MD, Dane Salazar MD, Karen Steger-May MA, Aaron M. Chamberlain MD, Ken Yamaguchi MD, MBA, Jay D. Keener MD

The critical shoulder angle (CSA) has been reported to be associated with rotator cuff disease and has been suggested as an etiology for cuff tears. However, it is unclear whether acromial morphologic characteristics such as CSA are a cause or effect because all studies to date have been retrospective.

Increased Risk of Revision, Reoperation, and Implant Constraint in TKA After Multiligament Knee Surgery

Steven I. Pancio MD, Paul L. Sousa MD, Aaron J. Krych MD, Matthew P. Abdel MD, Bruce A. Levy MD, Diane L. Dahm MD, Michael J. Stuart MD

The risk of major complications and revision arthroplasty after TKA in patients who previously underwent multiligament knee surgery have been poorly characterized.

Crosscultural Adaptation and Validation of the Korean Version of the New Knee Society Knee Scoring System

Seok Jin Kim MD, Mohnish Singh Basur DNB (ortho), Chang Kyu Park MD, Suri Chong MD, Yeon Gwi Kang MS, Moon Ju Kim MS, Jeong Seong Jeong MS, Tae Kyun Kim MD, PhD

The 2011 Knee Society Score(2011 KS Score) is used to characterize the expectations, symptoms, physical activity, and satisfaction of patients who undergo TKA and is widely used to assess the outcome of TKA. However, it has not been adapted or validated for use in Korea.

Is There an Association Between Hemoglobin A1C and Deep Postoperative Infection After TKA?

Jourdan M. Cancienne MD, Brian C. Werner MD, James A. Browne MD

Despite substantial research into the use of glycemic markers to stratify infection risk in patients with diabetes mellitus, there is little evidence to support a perioperative hemoglobin A1c (HbA1c) level associated with an increased risk of deep postoperative infection after TKA.

Freezing Nitrogen Ethanol Composite May be a Viable Approach for Cryotherapy of Human Giant Cell Tumor of Bone

Po-Kuei Wu MD, Cheng-Fong Chen MD, Jir-You Wang PhD, Paul Chih-Hsueh Chen MD, Ming-Chau Chang MD, Shih-Chieh Hung MD, PhD, Wei-Ming Chen MD

Liquid nitrogen has been used as adjuvant cryotherapy for treating giant cell tumor (GCT) of bone. However, the liquid phase and ultrafreezing (−196° C) properties increase the risk of damage to the adjacent tissues and may lead to perioperative complications. A novel semisolid cryogen, freezing nitrogen ethanol composite, might mitigate these shortcomings because of less-extreme freezing. We therefore wished to evaluate freezing nitrogen ethanol composite as a coolant to determine its properties in tumor cryoablation.

Is Limb Salvage With Microwave-induced Hyperthermia Better Than Amputation for Osteosarcoma of the Distal Tibia?

Kang Han MD, PhD, Peiye Dang MS, Na Bian MS, Xiang Chen MD, PhD, Tongtao Yang MD, PhD, QingYu Fan MD, PhD, Yong Zhou MD, PhD, Tingbao Zhao MD, PhD, Pingshan Wang MD, PhD

Amputation has been the standard surgical treatment for distal tibia osteosarcoma owing to its unique anatomic features. Preliminary research suggested that microwave-induced hyperthermia may have a role in treating osteosarcoma in some locations of the body (such as the pelvis), but to our knowledge, no comparative study has evaluated its efficacy in a difficult-to-treat location like the distal tibia.

Can a Bayesian Belief Network Be Used to Estimate 1-year Survival in Patients With Bone Sarcomas?

Rajpal Nandra MRCS, Michael Parry FRCS, Jonathan Forsberg MD, PhD, Robert Grimer FRCS

Extremity sarcoma has a preponderance to present late with advanced stage at diagnosis. It is important to know why these patients die early from sarcoma and to predict those at high risk. Currently we have mid- to long-term outcome data on which to counsel patients and support treatment decisions, but in contrast to other cancer groups, very little on short-term mortality. Bayesian belief network modeling has been used to develop decision-support tools in various oncologic diagnoses, but to our knowledge, this approach has not been applied to patients with extremity sarcoma.

Do Mesenchymal Stem Cells Derived From Atypical Lipomatous Tumors Have Greater Differentiation Potency Than Cells From Normal Adipose Tissues?

Hiroyuki Inatani MD, Norio Yamamoto MD, PhD, Katsuhiro Hayashi MD, PhD, Hiroaki Kimura MD, PhD, Akihiko Takeuchi MD, PhD, Shinji Miwa MD, PhD, Takashi Higuchi MD, Kensaku Abe MD, Yuta Taniguchi MD, Satoshi Yamada MD, PhD, Kiyofumi Asai MD, PhD, Takanobu Otsuka MD, PhD, Hiroyuki Tsuchiya MD, PhD

The p53 protein in mesenchymal stem cells (MSCs) regulates differentiation to osteogenic or adipogenic lineage. Because p53 function is depressed in most malignancies, if MSCs in malignancy also have p53 hypofunction, differentiation therapy to osteogenic or adipogenic lineage may be an effective treatment. We therefore wished to begin to explore this idea by evaluating atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) cells, because murine double minute 2 (MDM2) gene amplification, which leads to p53 hypofunction, is found in almost all ALT/WDLs.

Use of Compressive Osseointegration Endoprostheses for Massive Bone Loss From Tumor and Failed Arthroplasty: A Viable Option in the Upper Extremity

Krista A. Goulding MD, MPH, Adam Schwartz MD, Steven J. Hattrup MD, R. Lor Randall MD, Donald Lee MD, Damian M. Rispoli MD, Daniel M. Lerman MD, Christopher Beauchamp MD

Endoprostheses using principles of compressive osseointegration have shown good survivorship in several studies involving the lower extremity; however, no series to our knowledge have documented the use of this technology in the management of massive bone loss in the upper limb.

The 2017 ABJS Nicolas Andry Award: Advancing Personalized Medicine for Clubfoot Through Translational Research

Matthew B. Dobbs MD, Christina A. Gurnett MD, PhD

Clubfoot is one of the most common pediatric orthopaedic disorders. While the Ponseti method has revolutionized clubfoot treatment, it is not effective for all patients. When the Ponseti method does not correct the foot, patients are at risk for lifelong disability and may require more-extensive surgery.

Does N-terminal Pro-brain Type Natriuretic Peptide Predict Cardiac Complications After Hip Fracture Surgery?

Hiroki Ushirozako MD, Tsuyoshi Ohishi MD, PhD, Tomotada Fujita MD, Daisuke Suzuki MD, PhD, Kazufumi Yamamoto MD, PhD, Tomohiro Banno MD, Hiroyuki Takase MD, PhD, Yukihiro Matsuyama MD, PhD

Elderly patients with hip fracture are at risk for cardiac complications. N-terminal pro-brain type natriuretic peptide (NT-proBNP) has been shown to predict cardiac complications in surgical patients; however, to our knowledge, only two studies have evaluated the utility of this test in patients with hip fracture. We believe it is important to assess a more accurate cutoff value of NT-proBNP with exclusion of patients with renal failure.
