ABSTRACT Total knee arthroplasty has come under increasing scrutiny attributable to the fact that it is a high-volume, high-cost medical intervention in an era of increasingly scarce medical resources. Health-related quality-of-life outcomes have been developed such that healthcare providers might determine how good an intervention is and whether it is cost-effective. Total knee arthroplasty has been subjected to disease-specific, patient-specific, global health, functional capacity, and cost-to-utility outcome measures. Patient satisfaction is high (90%) after total knee arthroplasty and 93% of patients would have this operative procedure again. Large improvements in preoperative to postoperative WOMAC scores occurred (over 39 of 100 points in 82% of patients). Cost-to-quality outcomes demonstrated total knee arthroplasties are extremely cost-effective. This analysis documents total knee arthroplasty is a highly efficacious procedure that competes favorably with all medical and surgical interventions.

    ABSTRACT: Objetivo 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. Métodos 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. Resultados 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. Conclusões 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.

    ABSTRACT: This study aims to clarify the difference between surgical stress of total hip arthroplasty (THA) and total knee arthroplasty (TKA) under the same conditions through blood transfusion and ischemic extremity. Body temperature, white blood cell (WBC) count, the level of C-reactive protein (CRP), and interleukin-6 (IL-6) were measured for eleven patients undergoing THA and eight patients undergoing TKA. All the patients who underwent THA and TKA received a transfusion of 2 units of autologous blood but no transfusion with homologous blood, and the TKA surgery was performed without an air tourniquet. The first day after the surgery, there was no significant difference between the THA and TKA with respect to body temperature and CRP. However, there was a significant difference between the THA and TKA in WBC count (p < 0.05) and IL-6 (p < 0.01) on the first day after the surgery. In addition, there was a significant difference between the THA and TKA in IL-6 (p < 0.05) and CRP level (p < 0.05) on the seventh day after the surgery. The surgical stress of TKA was significantly larger than the surgical stress of THA. There may be more potential complications in the patients who underwent TKA than those who underwent THA.

    ABSTRACT: In a retrospective study with a population over 65 years, sports activity was conducted 6 years after cruciate retaining (CR) total condylar knee arthroplasty (TKA) with rotating platform (RP). 81 patients with a mean age of 71.8 ± 5.4 years were examined at the follow-up 6.4 ± 0.9 years postoperative. The mean of patients practiced active sport for 5.3 hours every week, and were active in sports 3.5 times per week. In mean 25% of the patients performed high impact sports, 47% medium impact sports and 52% low impact sports at follow-up. In KOOS sports patients reached a value of 60 ± 28, in WOMAC a total value of 12.1 ± 15.1. It can be concluded that in this population 50% of patients were active in medium and low impact sport 6 years after surgery. However, a quarter of patients was also active in high impact sports.
