Quality-of-life assessment among patients undergoing total knee arthroplasty in Manaus
Bibliographic record
Abstract
this study had the aim of assessing the quality of life among patients undergoing total knee arthroplasty (TKA). For this, the SF-36 and WOMAC questionnaires respectively were used to make comparisons with preoperative values. a prospective observational cohort study was conducted, with blinded analysis on the results from 107 TKAs in 99 patients, between June 2010 and October 2011. The present study included 55 knees/patients, among whom 73% were female and 27% were male. The patients’ mean age was 68 years. The SF-36 and WOMAC questionnaires (which have been validated for the Portuguese language) were applied immediately before and six months after the surgical procedure. the statistical and graphical analyses indicated that the variables presented normal distribution. From the data, it was seen that all the indices underwent positive changes after the surgery. despite the initial morbidity, TKA is a very successful form of treatment for severe osteoarthritis of the knee (i.e. more than two joint compartments affected and/or Ahlback classification greater than 3), from a functional point of view, with improvement of the patients’ quality of life, as confirmed in the present study. This study presented evidence level IV (description of case series), with analysis on the results, without a comparative study. avaliar a qualidade de vida em pacientes submetidos à artroplastia total do joelho (ATJ) com o uso dos questionários SF-36 (Medical Outcomes Study 36 – Item Short Form Health Survey) e WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) e compará-los com os valores pré-operatórios. foi feito um estudo prospectivo, observacional, coorte com análise cega dos resultados, com 107 ATJ em 99 pacientes, de junho de 2010 a outubro de 2011. Incluídos no estudo 55 joelhos/pacientes: 73% eram do sexo feminino e 27% do masculino. A média de idade foi de 68 anos. Foram aplicados os questionários SF-36 e WOMAC, validados para língua portuguesa, imediatamente antes e seis meses após o procedimento cirúrgico. a análise estatística e gráfica indica que as variáveis tiveram distribuição normal. Observando os dados, verifica-se que todos os índices sofreram alterações positivas depois da cirurgia. a artroplastia total do joelho, apesar da morbidade inicial, é uma modalidade bem-sucedida de tratamento para osteoartrite grave (mais de dois compartimentos articulares acometidos e/ou classificação de Ahlback maior do que 3) do joelho do ponto de vista funcional, com melhoria da qualidade de vida dos pacientes, dados esses confirmados nesta pesquisa. Nível de evidência IV, descrição de série de casos, com análise de resultados, sem estudo comparativo.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
