RESUMO
OBJECTIVE: Analyze data regarding total knee arthroplasty (TKA) carried out by the Public Health System (SUS) in the state of São Paulo from 2003 to 2010 and determine the projections expected for 2030. METHODS: A cross-sectional study (observational). We analyzed 10,952 patients who underwent primary total knee arthroplasty (PTKA) and revision total knee arthroplasty (RTKA) in the state of São Paulo between 2003 and 2010. The collection of data based on ICD-10 and HAA (Hospital Admission Authorization) were provided by the Tabnet and Sigtap software (Management System for the Table of Procedures, Medications, and OPM by SUS). The following variables were analyzed: gender, number of PTKAs and RTKAs, and their projections. The information collected formed a database developed in Excel® for Windows, and the statistical analysis was performed by the Stata® 11 SE and Minitab 16 software. RESULTS: There was a significant difference in the prevalence of TKA between genders (p<0.0001); most of the patients were females (7,891; 72%). The projection for 2030 when compared with the first year of the series, 2003, indicates a growth of 428% for PTKA and 1,380% for RTKA, with a greater increase percentage of RTKA in males than in females (1,558% and 1,318%, respectively). CONCLUSION: The proportions of the RTKA projection are much greater than those of PTKA by 2030, with a greater percentage of increase of RTKA in males than in females.

RESUMO OBJETIVO Analisar os dados referentes às artroplastias totais de joelho (ATJ) realizadas pelo Sistema Público de Saúde (SUS) no estado de São Paulo de 2003 a 2010 e determinar as projeções esperadas para 2030. MÉTODOS Estudo transversal (observacional). Foram analisados 10.952 pacientes que realizaram artroplastia total de joelho primária (ATJP) e revisão (ATJR) no estado de São Paulo entre 2003 e 2010. A coleta de dados baseados no CID-10 e AIH (Autorização de Internação Hospitalar) foram fornecidos pelo programa Tabnet e Sigtap (Sistema de Gerenciamento da Tabela de Procedimentos, Medicamentos e OPM do SUS). Foram analisadas as seguintes variáveis: gênero, número de ATJP e número de ATJR, além de suas projeções. As informações coletadas formaram um banco de dados desenvolvido no programa Excel® for Windows e a análise estatística foi realizada pelos softwares Stata® 11 SE e Minitab 16. RESULTADOS Houve diferença significativa na prevalência da ATJ entre os gêneros (p<0,0001), sendo a maioria do gênero feminino (7.891; 72%). A projeção para 2030 quando comparado com o primeiro ano da série, 2003, indica um crescimento de 428% para as ATJP e 1.380% nas ATJR, com uma porcentagem de aumento maior nas ATJR no gênero masculino do que no feminino (1.558% e 1.318%, respectivamente). CONCLUSÃO As proporções de projeção da ATJR se mostram muito maiores do que nas ATJP até o ano de 2030, percebendo-se uma porcentagem de aumento maior de ATJR no gênero masculino comparado ao feminino.
