Avaliar o equilíbrio e a qualidade de vida em pacientes submetidos a artroplastia total do joelho por gonartrose primária.


Pacientes com 60 anos ou mais foram avaliados em relação ao equilíbrio e à qualidade de vida antes da artroplastia total de joelho e seis meses após a cirurgia. Para avaliar o equilíbrio, foi usado o teste da Escala Motora para a Terceira Idade; para avaliar a qualidade de vida, foram usados os questionários Western Ontario and McMaster Universities Osteoarthritis Index e Short Form Health Survey. Um grupo controle de indivíduos saudáveis, pareado por idade e gênero, foi usado para comparação dos níveis de equilíbrio do grupo em estudo após a cirurgia.


Completaram o estudo 28 pacientes, em 37 artroplastias. A média de idade foi de 70,18 ± 6,17 anos. Em todas as variáveis analisadas, observou‐se significância estatística (p ≤ 0,05) para melhoria do equilíbrio e da qualidade de vida após a artroplastia. Observou‐se que, após artroplastia do joelho, o nível de equilíbrio não alcança o nível esperado para indivíduos saudáveis (p ≤ 0,05).


A artroplastia total de joelho é capaz de melhorar o equilíbrio seis meses após a cirurgia, bem como todos os domínios da qualidade de vida. No entanto, não é capaz de restaurar o equilíbrio comparável àquele dos indivíduos saudáveis.


To evaluate the change in balance and quality of life in patients undergoing total knee arthroplasty for primary gonarthrosis.


Patients aged 60 years or older were evaluated in relation to the balance and quality of life before total knee arthroplasty and six months after surgery. To assess balance, this study used the Motor Scale Test for the Elderly; quality of life was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index questionnaire and the Short Form Health Survey. A control group consisting of healthy adults, age‐ and gender‐paired, was used to compare the balance after surgery results.


Twenty‐eight patients completed the study, of a total of 37 arthroplasties. The mean age was 70.18 ± 6.17 years. All variables were statistically significant (p ≤ 0.05) for improved balance and quality of life after arthroplasty. It was observed that, after knee arthroplasty, the level of balance does not reach that expected for healthy individuals (p ≤ 0.05).


Total knee arthroplasty is effective at improving balance six months after surgery, as well as all domains of quality of life. However, it is not able to restore balance to a level comparable to that of healthy individuals.
