RESUMO

BACKGROUND: The combination of exercise therapy combined with nutritional supplementation (Nutr) is widely used for frail or sarcopenic older persons. However, the effects of Nutr in elderly patients after fast-track total hip arthroplasty (THA) are unknown. This study examined the effects of perioperative Nutr on muscle strength, functional performance, and quality of life (QOL) in frail elderly women after fast-track THA. METHODS: A total of 58 frail elderly women aged 65-80 years scheduled for unilateral primary THA were randomly allocated to two groups: the physical exercise (Ex) combined with Nutr (Ex + Nutr; n = 29) group, and the Ex alone (Ex; n = 29) group. Protein and vitamin D supplements were provided daily from 4 weeks preoperatively to 8 weeks postoperatively (12 weeks) to the patients in the Ex + Nutr group, whereas the Ex group did not receive any supplements. Surgery and postoperative rehabilitation programmes during intervention were identical in both groups. Hip abductor and knee extensor muscle strength, functional performance (Timed Up & Go test, Harris Hip Score), and QOL (Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire) were assessed at baseline and at 12 weeks (8 weeks postoperatively). RESULTS: After the intervention, hip abductor muscle strength on the contralateral leg and knee extensor muscle strength on both sides significantly improved in the Ex + Nutr group compared to the Ex group (p = 0.03, 0.01, and 0.01, respectively). However, hip abductor muscle strength on the operated side did not differ significantly between the groups (p = 0.23). There were no significant differences in functional performance and QOL. CONCLUSION: Ex + Nutr does not have an additional effect on the improvement of hip abductor strength, functional performance, and QOL compared to Ex alone after fast-track THA. However, significant improvements were observed in the strength of some muscles after fast-track THA. TRIAL REGISTRATION: UMIN 000042964. THE IRB APPROVAL: This study was approved by the Mirai Iryo Reesearch Center (approval number TGE1602-115).
