RESUMOIntrodução: O futebol é um esporte muito praticado em nosso meio, ocasionando uma grande incidência de lesões do ligamento cruzado anterior (LCA) . Frequentemente há necessidade de tratamento cirúrgico para se permitir o retorno à sua prática, e cada vez mais são utilizados os tendões isquiotibiais como enxertos de escolha para a técnica cirúrgica. Existem poucos dados na literatura a respeito do retorno à prática do futebol em nível amador após esse tipo de tratamento. Objetivo: Avaliar o índice de retorno à prática do futebol entre atletas amadores submetidos à reconstrução do LCA , utilizando-se como enxerto os tendões semitendíneo e grácil. Métodos: Foram avaliados 97 pacientes submetidos à reconstrução do LCA com seguimento mínimo de 2 anos. A avaliação foi feita através da escala de Lysholm e do questionamento direto a respeito do retorno à prática de esportes, com ênfase ao retorno à prática do futebol amador. Resultados: 60,8% dos pacientes operados voltaram a jogar futebol. Entre aqueles que não voltaram a praticar futebol, 9,3% continuaram a prática de outros esportes, sem que este fato estivesse relacionado com a lesão do joelho e 11,4% pararam de praticar esportes, relacionando o abandono da prática diretamente a sintomas no joelho operado. Um grande número (18,5%) de pacientes informou que não retornou ao futebol devido a variadas causas relacionadas a fatores psicológicos tais como: perda de motivação, medo de uma nova lesão e mudança de estilo de vida. Conclusão: É alto o índice de pacientes que não retornam à prática do futebol após o tratamento cirúrgico por motivos psicológicos. Portanto, existe a necessidade de mais estudos nesse campo a fim de selecionarmos melhor os pacientes e, assim, melhorarmos as indicações cirúrgicas e, consequentemente, os resultados do tratamento da lesão do LCA.

The aim was to report on a rare case of patellar osteochondroma. A 60-year-old man presented a tumor on his left patella that had developed over a 10-year period, which is a rare occurrence, considering the patient's age and the site at which the tumor appeared. The clinical condition comprised mild pain and the presence of a mass, without limitation of flexion–extension or any neurovascular deficit. The tumor dimensions were 8 cm longitudinally × 6 cm transversally × 3 cm anteroposteriorly. It was hardened and was adhering to the patellar bone plane. On radiographs and tomographic scans, we observed areas of greater density corresponding to bone and other less dense areas that could correspond to slow-growing cartilage, with irregularities on the patellofemoral joint surface. Simple resection of the tumor was performed, and the anatomopathological examination confirmed that it was a patellar osteochondroma. Osteochondroma, or osteocartilaginous exostosis, includes a large proportion of the benign bone tumors. It results from cell alterations that trigger unregulated production of spongy bone. It is basically treated by means of surgical removal of the tumor mass. This is not essential, but is recommended in order to avoid lesions caused by contiguity and the risk of malignant transformation.

Objective: To evaluate the intra-observer reproducibility of Schatzker classification for tibial plateau fractures through smartphone applications.Methods: Radiographs were evaluated in two incidences (anteroposterior and profile) and CT slices (axial, sagittal and coronal) of 37 patients with tibial plateau fracture. Two evaluators, knee surgery experts, classified the cases by viewing the images of the isolated radiographs and then X-rays associated with CT slices in four different stages via smartphones and then presential assessment. Data were statistically analyzed with the Kappa coefficient (k).Results: There was intra-observer agreement by comparing the two methods of evaluation: display or via smartphone, and the analysis made showed statistical significance.Conclusion: The use of smartphones did not affect the reliability of Schatzker classification. Level of Evidence III, Diagnostic Study - Investigating a Diagnostic Test.

The aim of this study was to describe surgical features of resection of hemimelic epiphyseal dysplasia of the patella. We already described the clinical and imaging features in another article. The patient was a six-year-old boy with a tumor in his right knee measuring 12 cm longitudinally and 6 cm transversally, which was adhering to the patella and had been slowly growing for two years. Biopsy findings were suggestive of a benign osteochondromatous lesion, without a defined diagnosis. Imaging examinations such as radiography and tomography showed areas of bone formation and radiotransparent areas, while magnetic resonance imaging showed areas of hypo and hypersignal in T1 and T2, of estimated size 8.5 cm longitudinally and 6 cm transversally. The tumor growth was surgically resected and curettage was performed on the epiphyseal nucleus of ossification of the upper and medial centers of the patella, with good patellar remodeling and normal development. The patient did not present any recurrence of the lesion up to the time of reaching skeletal maturity.
