ABSTRACT
ABSTRACT

Objective:

We aimed to investigate the change in bone mineral density (BMD) in the first postoperative year in patients that underwent total knee arthroplasty (TKA) due to primary osteoarthritis of the knee.

Methods:

Preoperative and first postoperative year dual-energy X-ray absorptiometry measurements of 76 patients with knee osteoarthritis, who undergone surgery between 2016 and 2018 due to the recommendation for TKA, were statistically evaluated in the study.

Results:

Of the 19 patients with a normal BMD in the preoperative period, 73.7% (n = 14) continued to have a normal BMD in the postoperative period. Of the 34 patients with a low BMD (osteopenia) in the preoperative period, 91.2% (n = 31) did not show any change, whereas osteoporosis was observed in two patients (5.9%) in the postoperative period. Of the 23 patients with osteoporosis in the preoperative period, 95.7% (n = 22) did not show any change, whereas osteopenia was observed in one patient (4.3%) in the postoperative period. Both the T and Z scores of the spine (L1-L4) and proximal femur showed a slightly positive trend, however, with an insignificant statistical difference (p ≥ 0.05).

Conclusion:

Patients that underwent TKA experienced a statistically insignificant bone gain at the spine and proximal femur twelve months after the surgery. Level of Evidence III, Therapeutic Studies Investigating the Results of Treatment.
RESUMO
RESUMO

Objetivo:

O objetivo foi investigar a alteração na densidade mineral óssea (DMO) no primeiro ano pós-operatório em pacientes submetidos à Artroplastia Total do Joelho (ATJ) por osteoartrite primária do joelho.

Métodos:

As medidas de absortiometria radiográfica com dupla energia no pré-operatório e no primeiro ano pós-operatório de 76 pacientes com osteoartrite do joelho, operados entre 2016 e 2018 devido à indicação de ATJ, foram avaliadas estatisticamente no estudo.

Resultados:

Dos 19 pacientes com DMO normal no pré-operatório, 73.7% (n = 14) continuaram com DMO normal no pós-operatório. Dos 34 pacientes com baixa DMO (osteopenia) no pré-operatório, 91.2% (n = 31) não apresentaram alteração, enquanto osteoporose foi observada em dois pacientes (5.9%) no pós-operatório. Dos 23 pacientes com osteoporose no pré-operatório, 95.7% (n = 22) não apresentaram alteração, enquanto osteopenia foi observada em um paciente (4.3%) no pós-operatório. Os escores T e Z da coluna vertebral (L1-L4) e do fêmur proximal mostraram uma tendência levemente positiva, mas a diferença foi estatisticamente insignificante (p ≥ 0.05).

Conclusão:

Os pacientes submetidos à ATJ apresentaram um ganho ósseo estatisticamente insignificante na coluna vertebral e no fêmur proximal doze meses após a cirurgia. Nível de Evidência III, Estudos Terapêuticos - Investigação dos resultados do tratamento.
