Abstract
INTRODUCTION: Osteoporotic fractures increase mortality and morbidity in patients who suffer them. Also, periprosthetic fractures are challenging to treat and have a major impact in our health systems. The FRAX® algorithm is a tool that calculates the 10-year probability of osteoporotic fracture for a given patient. In our study, we used the FRAX® algorithm to assess the risk of osteoporotic fracture in patients who had previously undergone total knee arthroplasty (TKA) or had suffered a periprosthetic fracture involving a TKA.
METHODS: We used the FRAX® algorithm to assess the 10-year probability of osteoporotic fracture in patients who were admitted in our hospital for a periprosthetic fracture around the knee and those who underwent TKA and gave consent to enter our study. Patients in the TKA group were separated according to their BMI in two categories (<30 and ≥30).
RESULTS: 37 patients were included in the TKA group and 15 in the periprosthetic group. In the TKA group, we found that the patients with lower BMI (<30) had a significantly higher risk of both hip fracture and major osteoporotic fracture than those with a higher one (≥30). We found no statistical significant differences for either risk (hip fracture and major osteoporotic fracture) between the TKA and the periprosthetic group.
CONCLUSION: The FRAX® algorithm was found to be a useful tool in order to predict the risk of osteoporotic fracture. Low BMI was found to be risk factor for the development of osteoporotic fractures.

Key words: FRAX, osteoporotic, fracture, periprosthetic, TKA
