          ABSTRACT

          Objective:

          To compare the long-term effects of a brace designed to stabilize the patellofemoral (PF) joint in comparison to a standard neoprene sleeve for the knee with patellar hole in patients with patellofemoral osteoarthritis (PFOA).

          Methods:

          38 patients with PFOA and comorbidities received either a functional PF brace (Study Group, SG) or a neoprene sleeve for the knee (Control Group, CG). Both groups received clinical treatment to OA and comorbidities according to a program from the institution. Patients were evaluated with Western Ontario and MacMaster (WOMAC) and Lequesne questionnaires, 30-second chair stand test (30CST), Timed Up and Go (TUG), anthropometric measures and self-reported physical activity in minutes/week at inclusion, one, three and twelve months after placing the brace. X-Rays were taken to measure the angles.

          Results:

          At one year there was more abandonment in the CG without differences in weight and body mass index between groups during the study. The SG maintained improvements in Lequesne and WOMAC total and subsets during the year, whereas the CG returned to baseline values for pain, function and total (p < 0.01). TUG and 30CST results were always better in the study group without any clinically important improvement in both groups.

          Conclusion:

          Long-term use of functional brace added to self-management program improves pain and function in patients with PFOA . Level of Evidence II, Lesser quality RCT (eg, < 80% followup, no blinding, or improper randomization).

          RESUMO

          Objetivo:

          Comparar o efeito a longo prazo de uma órtese destinada a estabilizar a articulação fêmoro-patelar em comparação com uma de neoprene com orifício para patela em pacientes com osteoartrite fêmoro-patelar (OAFP).

          Métodos:

          Trinta e oito pacientes com OAFP e comorbidades receberam ou uma órtese funcional fêmoro-patelar (grupo estudo, GE) ou uma joelheira de neoprene com orifício para patela (grupo controle, GC). Os grupos receberam tratamento clínico da osteoartrite e comorbidades conforme programa da instituição. Foram avaliados com os questionários de WOMAC e Lequesne, testes de senta e levanta em 30 segundos (TSL30) e Timed-Up-and-Go (TUG), medidas antropométricas e minutos de atividade física semanal à inclusão, com um, três e doze meses depois da colocação da órtese. Radiografias foram realizadas para mensurar ângulos fêmoro-tibiais.

          Resultados:

          Houve mais abandono no GC, sem diferenças de peso, índice de massa corpórea e atividade física entre os grupos durante o estudo. GE manteve melhoras de Lequesne e WOMAC total e subdomínios durante todo o estudo, enquanto o GC piorou progressivamente após o primeiro mês (p < 0,01). TUG e TSL30 tiveram melhoras não clinicamente relevantes para ambos os grupos.

          Conclusão:

          O uso a longo prazo da órtese funcional adicionado ao tratamento clínico melhora a dor e a função dos pacientes com OAFP. Nível de Evidência II, Evidence II,ECRC de menor qualidade (por exemplo, < 80% de acompanhamento, sem mascaramento do código de randomização ou randomização inadequada).

          The timed "Up & Go": a test of basic functional mobility for frail elderly persons.

          This study evaluated a modified, timed version of the "Get-Up and Go" Test (Mathias et al, 1986) in 60 patients referred to a Geriatric Day Hospital (mean age 79.5 years). The patient is observed and timed while he rises from an arm chair, walks 3 meters, turns, walks back, and sits down again. The results indicate that the time score is (1) reliable (inter-rater and intra-rater); (2) correlates well with log-transformed scores on the Berg Balance Scale (r = -0.81), gait speed (r = -0.61) and Barthel Index of ADL (r = -0.78); and (3) appears to predict the patient's ability to go outside alone safely. These data suggest that the timed "Up & Go" test is a reliable and valid test for quantifying functional mobility that may also be useful in following clinical change over time. The test is quick, requires no special equipment or training, and is easily included as part of the routine medical examination.

            Development of criteria for the classification and reporting of osteoarthritis. Classification of osteoarthritis of the knee. Diagnostic and Therapeutic Criteria Committee of the American Rheumatism Association.

            For the purposes of classification, it should be specified whether osteoarthritis (OA) of the knee is of unknown origin (idiopathic, primary) or is related to a known medical condition or event (secondary). Clinical criteria for the classification of idiopathic OA of the knee were developed through a multicenter study group. Comparison diagnoses included rheumatoid arthritis and other painful conditions of the knee, exclusive of referred or para-articular pain. Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes. In contrast to prior criteria, these proposed criteria utilize classification trees, or algorithms.

              The individual and socioeconomic impact of osteoarthritis.

              Osteoarthritis (OA) is a highly prevalent, disabling disease, with a commensurate tremendous individual and socioeconomic burden. This Perspectives article focuses on the burden of OA for the individual, the health-care system and society, to draw attention to the magnitude of the current problem with some reference to projected figures. We have an urgent opportunity to make fundamental changes to the way we care for individuals with OA that will have an effect upon the direct and indirect costs of this disease. By focusing on the burden of this prevalent, disabling, and costly disease, we hope to highlight the opportunity for shifts in health-care policy towards prevention and chronic-disease management.
