The Effect of Plasma Rich in Growth Factors on Pattern Hair Loss: A Pilot Study
Autologous growth factors have proved to promote tissue regeneration in various medical fields. This study, by TOBI Faculty Eduardo Anitua, looks into the role of PRP (platelet-rich plamas) in hair follicle restoration. The objective of this study was to evaluate the safety and clinical efficacy of plasma rich in growth factors (PRGFs) for the treatment of androgenetic alopecia (AGA). Patients declared an overall positive satisfaction, and a high clinical improvement score was achieved when comparing premacrophotographs and postmacrophotographs. Although randomized clinical trials are needed, this study provides preliminary data supporting the positive therapeutic effect of autologous growth factors on hair follicle regeneration.

Cellular acidification as a new approach to cancer treatment and to the understanding and therapeutics of neurodegenerative diseases
Eduardo Anitua, MD, of the Biotechnology Institute (BTI) of Vitoria, Spain, published this study on cellular acidification as a new approach to cancer treatment. During the last few years, the understanding of the dysregulated hydrogen ion dynamics and reversed proton gradient of cancer cells has resulted in a new and integral pH-centric paradigm in oncology, a translational model embracing from cancer etiopathogenesis to treatment. The abnormalities of intracellular alkalinization along with extracellular acidification of all types of solid tumors and leukemic cells have never been described in any other disease and now appear to be a specific hallmark of malignancy. As a consequence of this intracellular acid-base homeostatic failure, the attempt to induce cellular acidification using proton transport inhibitors and other intracellular acidifiers of different origins is becoming a new therapeutic concept and selective target of cancer treatment, both as a metabolic mediator of apoptosis and in the overcoming of multiple drug resistance (MDR). Importantly, there is increasing data showing that different ion channels contribute to mediate significant aspects of cancer pH regulation and etiopathogenesis. Finally, we discuss the extension of this new pH-centric oncological paradigm into the opposite metabolic and homeostatic acid-base situation found in human neurodegenerative diseases (HNDDs), which opens novel concepts in the prevention and treatment of HNDDs through the utilization of a cohort of neural and non-neural derived hormones and human growth factors.

Biologic Approaches for the Treatment of Partial Tears of the Anterior Cruciate Ligament: A Current Concepts Review.
Anterior cruciate ligament reconstruction (ACLR) has been established as the gold standard for treatment of complete ruptures of the anterior cruciate ligament (ACL) in active, symptomatic individuals. In contrast, treatment of partial tears of the ACL remains controversial. Biologically augmented ACL-repair techniques are expanding in an attempt to regenerate and improve healing and outcomes of both the native ACL and the reconstructed graft tissue. The purpose of this literature review, by TOBI Faculty Ignacio Dallo, MD, is to review the biologic treatment options for partial tears of the ACL.

Characteristics of Orthopedic Publications in High-Impact General Medical Journals
Orthopedic studies are occasionally published in high-impact general medical journals; these studies are often given high visibility and have significant potential to impact health care policy and inform clinical decision-making. The purpose of this review, by TOBI Faculty alumni Robert Marx, MD, was to investigate the characteristics of operative orthopedic studies published in high-impact medical journals. The number of orthopedic studies published in high-impact medical journals is relatively low; however, these studies demonstrate methodological characteristics that may bias toward nonoperative treatment. Careful analysis and interpretation of orthopedic studies published in these journals is warranted

Comparison of Revision Rates of Non-modular Constrained Versus Posterior Stabilized Total Knee Arthroplasty: a Propensity Score Matched Cohort
TOBI Faculty alumni Robert Marx, MD, published this article on different options for attaining stability during total knee arthoplasty (TKA). Although traditional constrained total knee prostheses have generally been used in conjunction with intramedullary stems, some devices have been widely used without the use of stems, referred to as non-modular constrained condylar total knee arthroplasty (NMCCK). The aim of this study was to compare revisions rates after total knee replacement with a non-modular constrained condylar total knee (NMCCK) compared to a posterior-stabilized (PS) design.

Effects of sensor position on kinematic data obtained with an inertial sensor system during gait analysis of trotting horses.
TOBI Faculty alumni Wayne McIlwraith, DVM, works in this publication to determine the effects of altering location of right forelimb and pelvic sensors on kinematic data obtained with a commonly used inertial sensor system during gait analysis of trotting horses. He studied 12 horses with mild to moderate lameness of at least 1 hind limb, with or without lameness of the forelimbs. Results of this study indicated that a 2-cm change in the location of the pelvic sensor during kinematic gait analysis had a significant effect on hind limb kinematic data of the system used. Therefore, placement of this sensor needs to be anatomically accurate.

Responsible, Safe, and Effective Prescription of Opioids for Chronic Non-Cancer Pain: American Society of Interventional Pain Physicians (ASIPP) Guidelines
Longtime TOBI faculty, and director of the TOBI 2017 Interventional Spine Lab Annu Navani, MD, published this important set of guidelines for the prescription of opioids for the management of chronic non-cancer pain. The purpose of this set of ASIPP guidelines is to develop a consistent philosophy among the many diverse groups with an interest in opioid use as to how appropriately prescribe opioids, to improve the treatment of chronic non-cancer pain and to reduce the likelihood of drug abuse and diversion. These guidelines are intended to provide a systematic and standardized approach to this complex and difficult arena of practice, while recognizing that every clinical situation is unique. The literature pertaining to opioid use, abuse, effectiveness, and adverse consequences was reviewed, with a best evidence synthesis of the available literature, and utilized grading for recommendation as described by the Agency for Healthcare Research and Quality (AHRQ).

Commercial Separation Systems Designed for Preparation of Platelet-Rich Plasma Yield Differences in Cellular Composition
The role of platelet-rich plasma (PRP) in the treatment of sport-related injuries is unclear, largely due to the heterogeneity of clinical results. In this study, Kristin Oliver, MD, TOBI 2017 Speaker and Faculty, aims to compare the composition of PRP produced with five different commercially available systems, focusing on cellular concentrations and pH. Aside from platelet concentration and capture efficiency, significant compositional differences were identified between preparation systems. Caution should be employed when interpreting clinical results of studies utilizing PRP, as the role of compositional differences and their effect on outcome are unknown. Further study is necessary to determine the clinical significance of these differences.

Precision and Accuracy of Identification of Anatomical Surface Landmarks by 30 Expert Hip Arthroscopists
TOBI Faculty alumni Jason Snibbe, MD, conducted this study to assess 30 expert hip arthroscopists’ ability to identify common surface landmarks used during hip arthroscopy. An ultrasonographer performed a musculoskeletal ultrasound examination and applied labels as well, and a photographer documented the examiner labels after obtaining overhead and lateral digital images with use of fixed camera mounts. Examiner labels demonstrated the highest potential for injury because of anterior portal inaccuracy. Expert hip arthroscopists varied in their ability to accurately and precisely identify common surface landmarks about the hip, using only manual palpation.
