Epidemiologic Study of Gene Distribution in Romanian and Brazilian Patients with Non-Cicatricial Alopecia.

Background: Androgenetic alopecia (AGA) and alopecia areata (AA) are the most common types of non-cicatricial alopecia. Both diseases have limited effective therapeutic options and affect patient quality of life. Pharmacogenetic tests can help predict the most appropriate treatment option by evaluating the single nucleotide polymorphisms (SNPs) corresponding to genes related to alopecia. The objective of the study was to evaluate and compare selected SNPs and genes in AA and AGA patients from Romania and Brazil. Materials and Methods: We performed a retrospective study regarding the associations between AA and AGA and 45 tag SNPs of 15 genes in 287 Romanian and 882 Brazilian patients. The DNA samples were collected from oral mucosa using a swab. The SNPs were determined by the qPCR technique. Each genetic test displays the subject's genotype of the selected gene and the prediction of a successful treatment (e.g., genotype AA of the GR-alpha gene is related to a predisposition to normal sensibility to topical glucocorticoid, and, therefore, glucocorticoids should be effective). Results: The GR-alpha, GPR44-2, SULT1A1, and CRABP2 genes were statistically significantly different in Brazil compared to Romania. The SULT1A1 activity that predicts the response to minoxidil treatment showed in our analysis that minoxidil is recommended in half of the cases of AGA and AA. Patients with AGA and a high expression of SRD5A1 or PTGFR-2 may benefit from Dutasteride or Latanoprost treatment, respectively. Most of the studied genes showed no differences between the two populations. Conclusions: The DNA analysis of the patients with alopecia may contribute to a successful treatment.

Severe dysphagia due to an esophageal duplication cyst in sixth decade, unusual presentation of a rare pathology.

BACKGROUND: Esophageal duplication cysts are rare congenital tumors usually diagnosed and treated during childhood. Most of them are located in the mediastinum and appear as a mass besides the esophagus. Unfortunately, symptoms are non-specific and depend on the size and location of the mass; therefore, they can easily be missed. If symptoms appear, surgical resection is necessary to prevent troublesome complications. CASE PRESENTATION: We present the case of a 60-year-old woman who presented with severe progressive dysphagia and epigastric pain. After further evaluation, a paraesophageal cystic mass was found, and surgery was required. Non-communicating esophageal duplication cyst was the final diagnosis. CONCLUSION: Esophageal duplication cysts are a rare pathology in adults; their symptoms will vary depending on their size and location. Preoperative diagnosis is difficult as symptoms are non-specific and can be missed. If severe dysphagia, pain, or any other complication appears, surgery should not be delayed.

Remote, asynchronous training and feedback enables development of neurodynamic skills in physiotherapy students.

BACKGROUND: During the COVID-19 pandemic, face-to-face teaching and learning of physiotherapy practical skills was limited. Asynchronous, remote training has been effective in development of clinical skills in some health professions. This study aimed to determine the effect of remote, asynchronous training and feedback on development of neurodynamic skills in physiotherapy students. METHODS: Longitudinal repeated measurements study, across four training sessions. Participants engaged in a remote training program for development of upper limb neurodynamic techniques. In this sequential training, participants viewed the online tutorial, practiced independently, and uploaded a video of their performance for formative assessment and feedback from a trained instructor via a checklist and rubric. RESULTS: Intra-subject analyses of 60 third-year physiotherapy students showed that the target standard of performance, with no further significant change in scores, was attained following session 2 for the checklist and session 3 for the rubric. This shows that two sessions are required to learn the procedures, and three sessions yield further improvements in performance quality. CONCLUSION: The remote, asynchronous training and feedback model proved to be an effective strategy for students' development of neurodynamic testing skills and forms a viable alternative to in-person training. This study contributes to the future of acquiring physiotherapy clinical competencies when distance or hybrid practice is required.

Heroin- and Fentanyl-Induced Respiratory Depression in a Rat Plethysmography Model: Potency, Tolerance, and Sex Differences.

The opioid overdose death toll in the United States is an ongoing public health crisis. We characterized the magnitude and duration of respiratory depression, the leading cause of death in opioid overdose cases, induced by heroin or fentanyl and the development of tolerance in male and female rats. We used whole-body plethysmography to first establish dose-response curves by recording breathing for 60 minutes post-intravenous opioid injection. We then tested the development of respiratory tolerance to acute heroin or fentanyl over several weeks and to chronic fentanyl with acute fentanyl or heroin challenge. Heroin and fentanyl each provoked dose-dependent respiratory depression. Heroin caused prolonged (45-60 minute) respiratory depression in female and male rats, characterized by decreased frequency, tidal volume, and minute ventilation and increased inspiratory time and apneic pause. Fentanyl produced similar changes with a shorter duration (10-15 minutes). High-dose heroin or fentanyl produced robust respiratory depression that was slightly more severe in females and, when given intermittently (acute doses 2 to 3 weeks apart), did not lead to tolerance. In contrast, chronic fentanyl delivered with an osmotic minipump resulted in tolerance to acute fentanyl and heroin, characterized by a shorter duration of respiratory depression. This effect persisted during withdrawal in males only. Our model and experimental design will allow for investigation of the neurobiology of opioid-induced respiratory depression and for testing potential therapeutics to reverse respiratory depression or stimulate breathing. SIGNIFICANCE STATEMENT: Fentanyl was more potent and had shorter duration in producing respiratory depression than heroin in both sexes, whereas female rats were more sensitive than males to heroin-induced respiratory depression. Tolerance/cross-tolerance develops in chronic fentanyl administration but is minimized with long interadministration intervals.

Acute small fiber neuropathy after Oxford-AstraZeneca ChAdOx1-S vaccination: A report of three cases and review of the literature.

Small fiber neuropathy usually presents with gradual and progressive chronic length-dependent pain. Acute small fiber neuropathy is rarely reported. Three patients with acute onset neuropathic pain after Oxford-AstraZeneca ChAdOx1-S vaccination are described. Two patients were identified at the Oxford University NHS Foundation Trust, Oxford, UK and one patient in Red de Salud UC Christus, Santiago, Chile. All patients underwent a clinical assessment that included a detailed neurological examination, laboratory investigations, nerve conduction studies, thermal threshold testing, and skin biopsy for intra-epidermal nerve fiber density. Patients seen in Oxford underwent MRI of the brain and spinal cord. Cerebrospinal analysis was not performed. Neuropathic symptoms (burning pain, dysaesthesias) developed in the hands and feet within 2 weeks of vaccination. On clinical examination, there was pinprick and thermal hyposensitivity in the area of neuropathic pain. Laboratory investigation, nerve conduction tests, sympathetic skin responses, and MRI showed no relevant abnormalities. Thermal thresholds were abnormal and intra-epidermal nerve fiber density in the lower leg was reduced. In two cases symptoms persist after several months. Three cases of definite acute small fiber neuropathy after Oxford-AstraZeneca ChAdOx1-S vaccination are described. At follow up, neuropathic pain was present in two of the patients.

Effects of Elbow Crutch Locomotion on Gluteus Medius Activation During Stair Ascending.

Crutches can help with the locomotion of people with walking disorders or functional limitations. However, little is known about hip muscle activation during stair ascending using different crutch locomotion patterns in people without disorders and limitations. Thus, we determined the acute effects of elbow crutch locomotion on gluteus medius (GM) activity during stair ascending. This comparative analytic cross-sectional study enrolled ten healthy men (22.0 ± 0.47 years). Participants climbed up the stairs with elbow crutches using one or two crutches, with ipsilateral or contralateral use, and after loading or unloading a limb. EMG signals were recorded from anterior, middle, and posterior portions of the GM and compared between the crutch conditions. The Kruskal-Wallis test and Dunn's multiple comparison test were performed (α = 5%). The activation of the GM increased with the ipsilateral use of crutches, with two crutches and three points, and when all the load depended only on one limb. GM activation decreased with contralateral use and in the unload limb. In conclusion, ascending stairs with elbow crutches alters the GM activation. The more critical factors were choosing the crutches' lateral use, the number of crutches, and if the limb is loaded or unloaded while ascending the stairs. Our findings can be helpful to increase or decrease the GM activation for those who use or will use crutches.

Epidemiological and Clinical Characteristics of Hospitalized Pediatric Patients with SARS-CoV-2 Infection in Mexico City, Mexico.

Background: Evidence from across the world suggests that the pediatric population shows different clinical manifestations and has a lower risk of severe presentation of SARS-CoV-2 infection compared to adults. However, Mexico has one of the highest mortality rates in the pediatric population due to SARS-CoV-2 infection. Therefore, our objective was to explore the epidemiological and clinical characteristics associated with a positive confirmatory test in the Mexican pediatric population admitted to a tertiary care hospital in Mexico City. Methods: Clinical, imaging and laboratory data were retrospectively collected from 121 children hospitalized during the period from March 4th, 2020, to August 8th, 2021. The patients were identified as suspicious cases according to the guidelines of the General Directorate of Epidemiology of Mexico. Real-time polymerase chain reaction (RT-PCR) tests were used to confirm SARS-CoV-2 infection. Categorical variables were compared using the Chi-square test, and propensity score matching was performed to determine univariate and multivariate odds ratios of the population regarding a positive vs. negative SARS-CoV-2 result. Results: Of the 121 children, 36 had laboratory-confirmed SARS-CoV-2 infection. The main risk for SARS-CoV-2-associated pediatric hospitalization was contact with a family member with SARS-CoV-2. It was also found that fever and fatigue were statistically significantly associated with a positive SARS-CoV-2 test in multivariate models. Clinical and laboratory data in this Mexican hospitalized pediatric cohort differ from other reports worldwide; the mortality rate (1.6%) of the population studied was higher than that seen in reports from other countries. Conclusion: Our study found that fever and fatigue at hospital presentation as well as an antecedent exposure to a family member with SARS-CoV-2 infection were important risk factors for SARS-CoV-2 positivity in children at hospital admission.

Interactive virtual scenarios as a technological resource to improve musculoskeletal clinical reasoning skills of undergraduate physiotherapy students.

BACKGROUND: Clinical reasoning is a fundamental competency in the learning process of health professionals. Since learning with traditional methods presents difficulties, teaching with interactive virtual scenarios is a good alternative. OBJECTIVE: To describe the impact of a blended training with interactive virtual scenarios for the development of clinical reasoning skills in undergraduate physiotherapy students. METHODS: A sample of 92 students solved eight storylines. Assessment error percentage, clinical pattern recognition, satisfaction, and the perception of difficulty were obtained. A proportions test was used to compare baseline and final assessments. To analyze the relationship between the variables, multilevel univariate logistic regression models were built. RESULTS: A significant difference was observed in the error percentage between baseline and final assessment (p < .001). Comparing the last storyline to the first one, there were 2.63 times more possibilities to correctly recognize the pattern. The error percentage was associated with the opportunity to recognize the pattern precisely (p < .001). Thus, for each increasing unit in the error percentage, the possibility to correctly recognize the pattern decreased by 11% (OR = 0.89). CONCLUSIONS: The use of this innovative blended training with virtual scenarios allowed students to systematically improve their recognition abilities of clinical patterns and decrease mistakes in the decision-making process.

O Subsistema Integrado de Atenção à Saúde do Servidor (SIASS) na perspectiva de servidores públicos de Instituições Federais de Ensino Superior / The Brazilian Integrated Health Care Subsystem for Civil Servants (SIASS) from the perspective of federal government employees from Higher Education Institutions

Resumo Introdução: a criação do Subsistema Integrado de Atenção à Saúde do Servidor Público (SIASS) veio em resposta à necessidade de ações em saúde e segurança voltadas para os servidores públicos federais, área que carecia de definições e orientações. Objetivo: analisar a implementação de ações de segurança e saúde no trabalho (SST) no âmbito do SIASS, na perspectiva de servidores públicos federais com cargos técnicos na área de SST lotados em Instituições Federais de Ensino Superior (IFES). Métodos: estudo qualitativo com realização de pesquisa bibliográfica e aplicação de questionário online. Para a análise das respostas dos entrevistados, utilizamos a perspectiva fenomenológica. Resultados: segundo os participantes, o foco de atuação das unidades do SIASS está voltado para perícias médicas, com ausência de ações voltadas para assistência e prevenção. O funcionamento da política se depara com falta de recursos e de equipe técnica. Conclusão: a política materializa legalmente uma oportunidade para sanar as omissões históricas no campo da SST voltada ao serviço público. Porém, as unidades do subsistema não conseguem cumprir o objetivo de garantir o direito à saúde dos servidores. Há necessidade de melhorias e os servidores que já atuam em SST podem ser utilizados como protagonistas nesse processo.

Abstract Introduction: the Brazilian Integrated Health Care Subsystem for Civil Servants (SIASS) was created to meet the occupational safety and health (OSH) needs of federal government employees, area that lacked definitions and guidelines. Objective: to analyze the implementation of occupational safety and health actions within the SIASS, from the perspective of federal government employees with safety and health technical jobs in Higher Education Institutions. Method: qualitative study using literature search and online questionnaire. The respondents' statements were analyzed through a phenomenological approach. Results: according to the participants, the SIASS performance focus on medical examinations, lacking care and prevention actions. The policy lacks resources and technical staff. Conclusion: the policy legally materializes an opportunity to remedy the historical omission regarding OSH in public services.

There is need for improvement, and the civil servants already working with OSH can play a key role in this process.

Importancia de la adherencia al tratamiento periodontal en pacientes diabéticos y el impacto del desapego / Importance of adherence to periodontal treatment in diabetic patients and the impact of detachment

La diabetes mellitus es una de las enfermedades sistémicas con mayor prevalencia en la población mundial. Este padecimiento representa uno de los factores de riesgo más importantes asociados con la enfermedad periodontal. El paciente con enfermedades crónicas como la diabetes necesita una disciplina convencida diaria y prolongada a través del tiempo (años) como única manera de reducir el impacto sistémico que deteriora la calidad de vida. Cuando se adhiere al tratamiento es posible observarlo en su condición estomatológica; sin embargo, cuando no se logra, se genera un deterioro en las condiciones bucales, principalmente enfermedad periodontal. En este artículo se presentan dos casos clínicos en los cuales se puede observar la mejoría de las condiciones bucales una vez que el paciente decide adherirse a su tratamiento. En el primero se aprecian las manifestaciones de manera notoria de un desapego en años posteriores. Se debe tener en cuenta que la adhesión al tratamiento no sólo depende de factores concernientes al paciente, también intervienen factores asociados al medio ambiente, situación económica, interacción médico-paciente, entre otros, por lo que resulta importante incentivar continuamente y acompañar al paciente en su tratamiento, así como conocer y entender la problemática de una enfermedad sistémica (AU)

Diabetes mellitus is one of the most prevalent systemic diseases in the world population. This condition represents one of the most important risk factors associated with periodontal disease. The patient with chronic diseases such as diabetes needs a daily and prolonged convinced discipline over time (years), as the only way to reduce the systemic impact, which deteriorates the quality of his life: when he has adherence to treatment it is possible to observe it in his stomatological condition, however when it is not achieved, a deterioration in the oral conditions is generated, mainly periodontal disease. This article presents two clinical cases where the improvement of oral conditions can be observed once the patient decides to adhere to their treatment. In the first one, the manifestations of a detachment in later years are noticeable. It should be taken into account that adherence to treatment does not only depend on factors concerning the patient. Also involved are factors associated with the environment, economic situation, doctorpatient interaction, among others, so it is important to continually encourage and accompany the patient in their treatment, as well as to know and understand the problem of a systemic disease (AU)

Pioneer plant species and fungal root endophytes in metal-polluted tailings deposited near human populations and agricultural areas in Northern Mexico.

As a consequence of industrial mining activity, high volumes of tailings are scattered around Mexico. Frequently, tailings contain heavy metals (HM) which entail threats against all organisms. The aim of this research was to identify plants and root fungal endophytes in polymetallic polluted tailings with the potential to be used in strategies of bioremediation. Four deposits of mine wastes, situated in a semi-arid region near urban and semi-urban populations, and agricultural areas, were studied. The physical and chemical characteristics of substrates, accumulation of HM in plant tissues, root colonization between arbuscular mycorrizal (AMF) and dark septate endophyte (DSE) fungi, and the identification of DSE fungi isolated from the roots of two plant species were studied. Substrates from all four sites exhibited extreme conditions: high levels in sand; low water retention; poor levels in available phosphorus and nitrogen content; and potentially toxic levels of lead (Pb), cadmium (Cd), and zinc (Zn). The native plants Lupinus campestris, Tagetes lunulata, and Cerdia congestiflora, as well as the exotic Cortaderia selloana and Asphodelus fistulosus, demonstrated a relevant potential role in the phytostabilization and/or phytoextraction of Pb, Cd, and Zn, according to the accumulation of metal in roots and translocation to shoots. Roots of eleven analyzed plant species were differentially co-colonized between AMF and DSE fungi; the presence of arbuscules and microsclerotia suggested an active physiological interaction. Fourteen DSE fungi were isolated from the inner area of roots of T. lunulata and Pennisetum villosum; molecular identification revealed the predominance of Alternaria and other Pleosporales. The use of native DSE fungi could reinforce the establishment of plants for biological reclamation of mine waste in semi-arid climate. Efforts are needed in order to accelerate a vegetation practice of mine wastes under study, which can reduce, in turn, their potential ecotoxicological impact on organisms, human populations, and agricultural areas.

Impacto de la pandemia en la práctica de los profesionistas de la salud oral en México / Impact of the COVID-19 pandemic in the oral health professionals' practice in Mexico

partir de la pandemia, los odontólogos han presentado una serie de complicaciones en su práctica diaria, la naturaleza misma de la profesión representa un alto riesgo de contagio y la posibilidad de generar una infección cruzada por el virus SARS-CoV-2, por lo que han tenido que limitar su labor a la atención de urgencias, adquiriendo insumos relacionados a incrementar los cuidados de su grupo de trabajo y del paciente. Objetivo: Conocer el impacto de esta plaga en la práctica de los profesionistas de la salud oral en México. Material y métodos: Se realizó un estudio descriptivo y transversal mediante la aplicación de una encuesta a través de redes sociales a odontólogos, los resultados se expresaron con tablas de frecuencias y porcentajes. Resultados: Se recibieron respuestas de 200 cirujanos dentistas con clínica privada, 71% comentó haber cerrado su consultorio al inicio de esta calamidad, en contraste, el 53.5% de profesionales afirmaron tener actualmente una consulta no restringida, refiriendo que se ha visto reducida entre 50 y 75%, la mayoría reconoce que han tenido que reforzar el uso de EPP y algunos protocolos de protección, 16.5% ha padecido COVID-19. Conclusiones: La pandemia ha generado un impacto económico importante en la práctica de los odontólogos, al combinarse la disminución del número de pacientes con el aumento de gastos. Se debe considerar a la odontología como una profesión de alto riesgo, por lo que este gremio debe ser tomado en cuenta para el plan de vacunación como parte importante del sector salud (AU)

Given the nature of their profession, the COVID-19 pandemic has brought complications in their daily practice to odontologists, who are at a high risk of contracting the disease, and the possibility of creating a cross infection by the SARS-CoV-2 virus. That is why odontologists have had to restrain their practice to attend to emergencies only and acquire consumables and equipment related to improve their patients' care and the safety of their work team. Objective: To know the COVID-19 pandemic impact in the oral health professionals' practice in Mexico. Material and methods: A transversal, descriptive study was conducted by using a survey through social networks to gather information from odontologists practicing in Mexico. Results were presented in frequency and percentage tables. Result: Responses of 200 dental surgeons in private practice were received. 71% said that they closed their office at the beginning of the pandemic. On the other hand, 53.5% of them currently have a non-restricted practice but it is reduced between 50 and 75%. Most of them recognized that they had to improve the use of PPE and add some protection protocols, 16.5% have suffered from COVID-19. Conclusions: This pandemic has generated an important economic impact in the odontological practice, combining the decrease in the number of patients with the increase in their office expenses. Odontology must be considered a high-risk profession and an important part of the health sector, consequently, these professionals must be included in the vaccination plan on a priority basis (AU)

Safety of Allogeneic Adipose Tissue-Derived Mesenchymal Stem Cells for the Treatment of Complex Perianal Fistulas Not Associated With Crohn's Disease: A Phase I Clinical Trial.

BACKGROUND: Anal fistula treatment aims to eradicate the fistula, preserve the sphincter, prevent recurrence, and allow an early return to daily activities for the patient. Because of the difficulty of achieving these goals, stem cell-based therapy has emerged for the treatment of complex perianal fistula with promising results. OBJECTIVE: The objective of this study was to evaluate the safety of allogeneic mesenchymal stem cells in the treatment of complex anal fistula in patients without Crohn's disease. DESIGN: This was a prospective nonrandomized phase I clinical trial. SETTINGS: This study was conducted at a second-level hospital. PATIENTS: Twenty consecutive patients diagnosed with a complex fistula were included. INTERVENTIONS: All patients received 40 × 106 allogeneic mesenchymal stem cells. In patients with 2 tracts, 20 × 106 stem cells were applied on each tract. MAIN OUTCOME MEASURES: The patients were discharged 24 hours after the procedure and were evaluated at 1, 2, 4, 8, 16, and 24 weeks after the application. The long-term follow-up was performed 1 year after the procedure. RESULTS: The procedure was performed in a total of 20 patients from October 1, 2016, to October 31, 2017; 1 patient was eliminated from the final data analysis. No adverse effects were reported within the first 24 hours, and all the patients were discharged asymptomatic. Three patients (15%) presented with perianal abscess. In 1 patient, the abscess appeared at the fourth week, and, in the other 2 patients, the abscess was diagnosed at week 8. Complete closure was achieved in 13 (69%) patients. LIMITATIONS: This was a nonrandomized controlled trial. CONCLUSION: The use of allogeneic mesenchymal stem cells as a treatment is a safe option for the management of complex perianal fistula not associated with Crohn's disease.

Review of current intracranial aneurysm flow diversion technology and clinical use.

Endovascular treatment of intracranial aneurysms (IAs) has evolved considerably over the past decades. The technological advances have been driven by the experience that coils fail to completely exclude all IAs from the blood circulation, the need to treat the diseased parent vessel segment leading to the aneurysm formation, and expansion of endovascular therapy to treat more complex IAs. Stents were initially developed to support the placement of coils inside wide neck aneurysms. However, early work on stent-like tubular braided structure led to a more sophisticated construct that then later was coined as a flow diverter (FD) and found its way into clinical application. Although FDs were initially used to treat wide-neck large and giant internal carotid artery aneurysms only amenable to surgical trap with or without a bypass or endovascular vessel sacrifice, its use in other types of IAs and cerebrovascular pathology promptly followed. Lately, we have witnessed an explosion in the application of FDs and subsequently their modifications leading to their ubiquitous use in endovascular therapy. In this review we aim to compile the available FD technology, evaluate the devices' peculiarities from the authors' perspective, and analyze the current literature to support initial and expanded indications, recognizing that this may be outdated soon.

Introducción: Las lesiones condrales de la rótula son un reto para el cirujano, principalmente en pacientes jóvenes y activos. La mayoría de los defectos condrales de la rótula son lesiones superficiales y pueden ser manejadas con técnicas de preservación articular; sin embargo, las lesiones profundas pueden requerir otro tipo de manejo. El objetivo de este artículo es comunicar el tratamiento de defectos osteocondrales de la rótula en pacientes jóvenes, mediante la técnica de aloinjerto fresco de donante cadavérico. materiales y métodos: Se seleccionaron pacientes con dolor anterior de rodilla, lesión condral de la rótula grado III-IV y que habían recibido o no algún tipo de manejo médico o quirúrgico. En estos pacientes, se usó un aloinjerto fresco de rótula con el fin de solucionar el cuadro y mejorar la función. Resultados: Todos los pacientes recuperaron la función y los arcos de movilidad, y no refirieron dolor. Se comprobó la integración del aloinjerto fresco al área receptora, sin evidencia de rechazos del tejido o infecciones. Conclusiones: El uso de aloinjerto fresco de rótula para tratar defectos osteocondrales amplios es una téc-nica quirúrgica valiosa, fácil de implementar, que no requiere una curva de aprendizaje extensa y que mejora considerablemente el dolor y la función en pacientes jóvenes. Nivel de Evidencia: IV

Introduction: Chondral lesions of the patella are a challenge for the surgeon, mainly in young and active patients. Most patellar chondral defects are superficial injuries and can be managed with joint preservation techniques; however, deep injuries may require other types of management. The objective of this article is to manage osteochondral defects of the patella in young patients, using the technique of fresh allograft from a cadaveric donor. Materials and methods: Patients with anterior knee pain, with grade III - IV chondral lesion of the patella and who had or had not undergone some type of medical or surgical management were included. They received a fresh patellar allograft that sought to provide a solution and improvement of the functionality. Results: In all cases, recovery of functionality and mobility, absence of pain and integration of the fresh allograft into the recipient area were achieved, without evidence of tissue rejection or infection. Discussion: The use of fresh patellar allograft for the management of wide osteochondral defects is a valuable surgical technique, easy to implement, that does not require a long learning curve and that considerably improves pain and functionality in young patients. Conclusions: The advent of fresh osteochondral grafts allows adequate management and evolution of patients, with the aim of favoring joint preservation and avoiding total knee arthroplasty over time. Level of Evidence: IV
