Objectives:To identify patients with a diagnosis of acute and complete ACL rupture that healed spontaneously, and to determine whether such healing is related to age, sex, type of rupture, resting time, and trauma mechanisms.Materials and Methods:30 patients with complete acute ACL rupture were evaluated by clinical diagnosis and Magnetic Resonance Image (MRI). Both Lysholm test and IKDC 2000 were used for subjective evaluation.Results:All patients improved from the first to the second consult, with the following results: Lachman (p <0.0406), pivot shift (p = 0.071), and anterior drawer (p <0.001). During the follow-up MRI, all patients showed signs of healing in ACL. With an average follow-up of 12 months for men (95% CI 6-17) and 13 months for women (95% CI 31 max.), a nearly complete clinical recovery could be inferred, as well as healing occurring independently of variables such as age, sex, or specific treatment (p = 0.795 and p = 0.841).Discussion:Despite this study size limitation, the objectives were achieved. There would be spontaneous ACL healing associated with a 3-month post-injury resting time, but it is unrelated to age, sex, specific physiotherapy treatments, or the use of immobilizers. Level of evidence: level of evidence IV

Introduction:Faced with a bucket meniscal lesion we have two treatment options. A frequently practiced option is to remove the bucket handle, another is to repair it. Generally, they are associated with ligament injuries. In this context, it has been shown that meniscal repair has a good result, but the evolution of isolated meniscal repairs is not entirely clear. The purpose of this systematic review is to determine the results after the repair of bucket handle injuries.Materials and Methods:A bibliographic search of the computerized database was carried out pubmed. Eight articles were included according to the inclusion and exclusion criteria. The results of interest included, level of evidence, number of patients, follow-up, average age, surgical technique,% cure,% failure, complications, associated injuries and average time from injury to surgical repair.Results:The works studied, on average, 43 patients, with ages between 16 and 33 years making 341 patients. The follow-up period was focused on 58 months. The percentage of cure varies from 52% to 98%.Conclusion:The isolated repair of this type of meniscal lesions has a good overall evolution associated with a low rate of failure and complicationsLevel of evidence:IVType of studysystematic review

Introduction:Knee pain is one of the most common complications in the trauma clinic. It is common to find patients who come to the office with a Nuclear Magnetic Resonance (MRI) who have a broken meniscus and who are looking for a lathe in the operating room. The majority of these patients are feasible for orthopedic treatment and it is sufficient to perform correct semiological maneuvers to determine it. Although there is a growing demand for knee MRI by members of the health team. The hypothesis of this work postulates that the NMR requested by the specialists in orthopedics and traumatology offer positive results both for the diagnoses and for the treatment plans.Objectives:The aim of this study is to compare the usefulness in diagnosis and in the therapeutic definition of knee MRIs requested by medical specialists.Materials and Methods:We retrospectively reviewed 1,186 knee MRI reports from January 1, 2015 to July 31, 2015, using the computerized clinical history system. These were classified according to the origin of the request for the images (specialists in orthopedics and traumatology, residents of traumatology and other medical specialties). This information was explored for its characterization.Retrospective study. Level of evidence IVResults:We obtained 33% (389) normal report of knee, significantly lower (p <0.001) to 67% reporting injuries. The proportion of studies requested was mostly by specialists in orthopedics and traumatology (59%), followed by the proportion required by different medical specialties (27%) and by those prescribed by traumatology residents (13%). The percentages of normal reports of those studies requested were different (p <0.05) 29, 42 and 32%, respectively.Conclusions:In primary care by physicians and residents of traumatology, the request for knee MRI reports a high percentage of normal reports. Specialists in orthopedics and traumatology request this exam with greater demand and present greater findings of injuries.

258 ResumenIntroducción: La artroscopia de rodilla es el procedimiento quirúrgico más común para tratar pacientes con lesiones meniscales o condrales. El objetivo de este trabajo fue comparar la eficacia de la anestesia raquídea versus la intrarticular en artroscopias simples de rodilla, evaluar la calidad de la anestesia, describir la incidencia de los efectos adversos y determinar las complicaciones en ambos casos. Materiales y Métodos: Estudio prospectivo, aleatorizado para comparar dos procedimientos anestésicos mediante la evaluación de la edad, el tiempo de cirugía, la duración de la anestesia, el tiempo de internación, el dolor, la conformidad con el procedimiento y los costos. Se utilizó el test t de Student para las estadísticas y probabilidades. Nivel de significación: p <0,05. Resultados: Se incluyó a 70 pacientes, 35 fueron operados con anestesia intrarticular y 35, con anestesia raquídea. El tiempo de internación fue mayor en el grupo de anestesia raquídea (7.34 h; rango 4-11) que en el grupo de anestesia intrarticular (3.43 h; rango 2-5), p <0,0001. En la variable costo, hubo una diferencia significativa a favor de la anestesia intrarticular con respecto a la anestesia raquídea (p <0,0001). Conclusión: Las ventajas encontradas a favor de la anestesia intrarticular fueron: estadías hospitalarias acortadas, se evitaron efectos indeseables de la anestesia raquídea (bloqueo motor, náuseas, vómitos, hipotensión, pérdida transitoria de esfínter urinario y retención urinaria [globo vesical]); disminución de los costos y mayor aceptación de los pacientes.Palabras clave: Artroscopia de rodilla; anestesia local; anestesia intrarticular. Nivel de Evidencia: ISpinal anesthesia versus intra-articular anesthesia in arthroscopic surgery of the knee Abstract Introduction: Knee arthroscopy is the most common surgical procedure to treat patients with meniscal and/or chondral injuries. The aim of this study was to compare the efficacy of spinal vs. intra-articular anesthesia in knee arthroscopy, to assess the quality of anesthesia, to describe the incidence of adverse effects and to determine the complications in both cases. Methods: Prospective, randomized study to compare two anesthetic procedures evaluating age, duration of surgery, duration of anesthesia, length of hospitalization, pain, patient satisfaction and costs. Student t test was used for statistics and probabilities. Level of significance: p <0.05.
