ABSTRACT

OBJECTIVE: To compare the effect of a brace designed to stabilize the patellofemoral joint to that of a patella-shaped neoprene sleeve with patella cut out in patients with patellofemoral osteoarthritis. METHODS: Fifty-seven patients with femoro-patellar osteoarthritis were allocated to two groups: patients with femoro-patellar functional brace and those with a neoprene knee with a patellar orifice. Both groups underwent clinical treatment of osteoarthritis and used medications daily 1 month before and up to 3 months after brace placement. They were evaluated with the WOMAC and Lequesne questionnaires and performed five times sit to stand test, Timed Up and Go test, and six minutes walk test immediately before and 1 and 3 months after brace placement. RESULTS: Both groups had improved pain, stiffness, and function with no difference between groups. Drug use decreased in both groups in the first month but increased in the third month. Naproxen use was progressively higher in the control group. CONCLUSION: Both knee orthoses improved pain and function and altered drug use only in the first month. Functional knee brace provided analgesia without increased use of naproxen. Level of Evidence IB, Randomized clinical trial.


OBJETIVO: Comparar o efeito de uma órtese destinada a estabilizar a articulação fêmoro-patelar, em comparação com uma de neoprene com orifício para rótula, em pacientes com artrose fêmoro-patelar. MÉTODOS: Cinquenta e sete pacientes com artrose fêmoro-patelar foram alocados em dois grupos conforme a joelheira que receberam: órtese funcional fêmoro-patelar e joelheira de neoprene com orifício para patela. Ambos os grupos foram orientados sobre o tratamento clínico da osteoartrite e preencherem o consumo diário de medicamentos um mês antes da colocação das órteses e até três meses depois da colocação das mesmas. Foram avaliados com o questionário de WOMAC e Lequesne e realizaram os testes de senta e levanta, Timed-up-and-go e o teste de caminhada de seis minutos, nos momentos imediatamente antes da colocação da órtese e após um e três meses. RESULTADOS: Ambos os grupos melhoram dor, rigidez e função sem diferença entre os grupos. O consumo de medicamentos diminuiu em ambos os grupos no primeiro mês, aumentando no terceiro mês. O consumo de naproxeno foi progressivamente maior no grupo controle. CONCLUSÃO: Ambas as joelheiras melhoraram a dor, a função e alteraram o consumo de medicamentos somente no primeiro mês. A joelheira funcional propiciou analgesia sem consumo aumentado de naproxeno. Nível de evidência IB, Ensaio clínico randomizado.

ABSTRACT

BACKGROUND: Although education is recommended for the treatment of knee osteoarthritis (KOA), its effectiveness in osteoarthritis (OA) remains low according to subjective questionnaires. The timed-up-and-go (TUG) and five-times-sit-to-stand tests (FTSST) reflect muscle strength and balance and could be used as objective measures of effectiveness. AIM: To measure the effect of an educational programme in patients with KOA by TUG and FTSST and correlate these results to those of subjective questionnaires. METHODS: Prospective randomised controlled trial of patients with KOA. Participants (n=198) were allocated into four groups. Three groups participated in 2 days of lectures with 1 (group 1), 2 (group 2) and 3-month (group 3) intervals between classes. Group 4 had no classes. Participants were asked to exercise at least three times a week. Half of the patients from all groups received bimonthly telephone calls reinforcing diet and exercise instructions. All four groups received the printed and video material presented in the classes. At baseline and at 1 year after initial assessment, patients performed the FTSST and TUG and answered WOMAC, Lequesne, SF-36 and Visual Analogue Scale questionnaires. RESULTS: The TUG results did not change at 1 year follow-up, whereas FTSST improved (average difference of 4.66, p<0.001) irrespective of the implementation of classes or telephone calls. Both baseline and 1 year TUG and FTSST results correlated weakly (r<0.3) to the subjective functional, pain and quality of life results (p<0.001). CONCLUSIONS: This educational programme improved function as determined by lower limb muscle strength (FTSST) irrespective of the patients' subjective non-improvement. TRIAL REGISTRATION NUMBER: Clinical trials registration number: NCT01572051. LEVEL OF EVIDENCE: Level 1A.
