ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the relation between femoral rollback and range of motion (ROM) in patients with cruciate retaining (CR) and posterior stabilized (PS) total knee arthroplasty (TKA). METHODS: The study included 38 knees of 31 patients (26 female and 5 male) with primary knee arthrosis who underwent TKA. The posterior cruciate ligament (PCL) was sacrificed in 24 knees in the PS group and preserved in 14 in the CR group. Mean follow-up was 30.6 months. Patients were submitted to fluoroscopic lateral evaluation for ROM and femoral rollback assessment. RESULTS: Average ROM of the CR group was 106.43±9º and 105.43±11.7º for the PS group (p=0.78). Average femoral rollback was 10.5±9.7 mm and was significantly lower in the CR group (5.8±6.5 mm) than the PS group (13.2±10.5 mm) (p=0.026615). While there was no correlation between the femoral rollback and ROM for CR prostheses (p=0.78 and r=0.8), there was a significant correlation for PR prostheses (p=0.01 and r=0.49) with regression pointing to an increase of 0.545 degrees ROM for each unit of femoral rollback. CONCLUSION: Despite increase in femoral rollback and its relation with ROM in PS TKA, there were no differences in ROM between CR and PS TKA.

ABSTRACT

Objetivo: Analisar a influência do uso do dreno de sucção no resultado em curto prazo da cirurgia de reconstrução do ligamento cruzado anterior. Métodos: Foram avaliados, de forma prospectiva, os resultados de dois grupos de 30 pacientes submetidos à reconstrução cirúrgica do ligamento cruzado anterior por via artroscópica, com o terço central do ligamento patelar, fixado com dois parafusos de interferência metálicos por acesso único usando, num grupo, dreno de sucção instalado por contra-abertura, no outro, não. Os pacientes foram avaliados quanto a dor, amplitude de movimentos e perimetria dos membros a 5cm do pólo superior da patela com 24, 48 horas, sete e 14 dias de pós-operatório. Resultados: Não foi encontrada diferença estatisticamente significante quanto a dor nos dois grupos; contudo, os pacientes do grupo sem dreno apresentaram maior amplitude de movimentos aos 14 dias de pós-operatório (p = 0,000216), apesar de maior perimetria do lado operado (p = 0,000084). Conclusão: Não foi encontrada justificativa para o uso do dreno de sucção nessa cirurgia
