RESUMO
BACKGROUND: The purpose in the present study was to compare clinical and radiological outcomes of patients who had undergone a mobile-bearing unicompartmental knee arthroplasty (UKA) with either titanium niobium nitride (TiNbN) alloy implants or with fixed-bearing oxidized zirconium alloy implants. METHODS: The records of two consecutive cohorts for a total of 86 hypoallergenic implants were prospectively analyzed. The first cohort consisted of 49 consecutive implantations of the hypoallergenic UKA Journey Uni Oxinium (Ox Group), while the second consisted of 37 consecutive series of UKA Oxford (TiNbN Group). All patients were evaluated by two independent surgeons who were not involved in the index surgery. The clinical evaluation consisted of evaluating each patient's Oxford Knee Score and Knee Society Score day before surgery (T0), and with two consecutive follow-ups at T1 (minimum follow-up 9 months) and T2 (minimum follow-up 24 months). RESULTS: The two groups were homogeneous in all preoperative values, except Body Mass Index (BMI) and duration of final follow-up [both statistically higher (p < 0.05) in the TiNbN group]. Both groups showed a clinically significant improvement for all scores at final follow-up (p < 0.05). The only differences between the two groups involved a higher pre-operative Oxford Score in TiNbN group (p = 0.031), and different tibial and femoral angles at the final follow-up. CONCLUSIONS: Both TiNbN and Oxinium UKA procedures enabled patients from good to excellent clinical and radiographic outcomes after the final follow-up, regardless of the age, gender, BMI bearing type, and implant size. LEVEL OF EVIDENCE: LEVEL II: Comparative study.

O Acidente Vascular Cerebral (AVC), é uma das principais causas de internações e mortalidade no Brasil, dimensionando a sua magnitude como problema de saúde pública. A maior parte dos sobreviventes do AVC permanecem com alguma sequela, seja ela de ordem física, comunicacionais, funcionais, sensitivas, mentais ou emocionais. O presente artigo tem como objetivo, analisar dados dos sistemas de informações online do Instituto Brasileiro de Geografia e Estatística e do Departamento de Informática do Sistema Único de Saúde, para avaliar o perfil dos portadores de AVC e qual o seu grau de limitação. Trata-se de um estudo observacional transversal, realizado nos sistemas de informações online públicos brasileiros (IBGE/DATASUS), como base na Pesquisa Nacional de Saúde (PNS) realizada no ano de 2013. Verificou-se que o AVC ocorre igualmente em ambos os sexos, em prevalência de 39,8% dos casos na faixa etária de adultos jovens (30 a 59 anos), 69,8% das pessoas afetadas possuem baixo grau de escolaridade, e há proporção elevada na cor branca (48,2%) e parda (41,1%). O acesso ao processo de reabilitação demonstra-se deficiente, apenas 0,27% das pessoas realizaram fisioterapia para o AVC e 0,12% realizaram algum tipo de tratamento para reabilitação, prejudicando o quadro funcional do usuário. Salienta-se que os dados corroboram com estudos realizados, porém contrapõem no quesito de raça. Devido à alta taxa de pessoas com sequelas de AVC, evidencia-se a importância do processo de reabilitação. Portanto, a prevenção e o tratamento deste agravo em saúde estão relacionados a fatores condicionantes modificáveis, à mudança no perfil epidemiológico no país e ao acesso à serviços de reabilitação, sendo necessária a atuação interdisciplinar de profissionais capacitados e articulados com a rede de atenção pública.
A Cerebrovascular Accident (CVA) - or stroke - is one of the main causes of hospital admissions and mortality in Brazil, reaching a scale of a public health issue. The majority of CVA survivors have some sort of after effect, being them of physical, communicational, functional, sensitive, mental or emotional nature. This article has the purpose of analyzing data from the online information systems for the Brazilian Institute of Geography and Statistics (IBGE) and the IT Department of the Brazilian Health System (SUS) to assess the profile of CVA patients and their levels of limitation. This is a cross-sectional observational study carried out in the Brazilian public online information systems (IBGE/DATASUS), based in the National Health Survey (PNS) carried out in 2013. It has been found that stroke affects both genders, 39.8% of the cases in the age group of 30 to 59 years, 69.8% of the affected people have low educational level, and there is a high proportion in Caucasian (48.2%), and pardo (41.1%) populations. Access to the rehabilitation process is deficient, with only 0.27% of people undergoing physical therapy for stroke, and 0.12% performed some type of rehabilitation treatment, impairing the user's functional status. It should be noted that the data corroborate with other studies, however, they present contract on the race item. Due to the high rate of people with stroke sequels, the importance of the rehabilitation process is evident. Therefore, the prevention and treatment of this health issue are related to modifiable conditioning factors, the change in the epidemiological profile in the country and the access to rehabilitation services, requiring the interdisciplinary work of trained and articulated professionals with the network of public health care.
