Abstract
Background: Hinged prostheses are a good choice in the setting of complex knee arthroplasty. Nevertheless, the results could be different in the Latin-American people.
Methods: A retrospective follow-up was performed. Seventy-six patients underwent pTKA using hinged prosthesis from 2012 to 2017. Survival analysis was performed with the Kaplan-Meier method. Functional results were assessed using Oxford Knee Score (OKS), OKS-APQ (Activity and Participation Questionnaire) and KOOS-12. Radiologic assessment was performed at each follow-up. In all the surgeries the rotating-hinge prosthesis solved the cases of complex knee surgery.
Results: Seventy-six patients underwent pTKA using hinged prosthesis from 2012 to 2017. Survival analysis was performed with the Kaplan-Meier method. Functional results were assessed using Oxford Knee Score (OKS), OKS-APQ (Activity and Participation Questionnaire) and KOOS-12. Radiologic assessment was performed at each follow-up. In all the surgeries the rotating-hinge prosthesis solved the cases of complex knee surgery. Hinge prostheses for complex knee arthroplasty in Latin-American people have a 10-year survivorship of 90.8% which is within the range of 51% to 92.5%, shown in a recent literature review of non-Latin American world population.
Conclusions: Rotating Hinge prostheses are a good option for patients with major deformities, grade 3 ligament instability, neurological sequalae that compromises the knee joint and severe bone loss. The Latin-American population shows a similar behavior in terms of survivorship in comparison with the literature from the rest of the world. However, comparative studies with greater statistical power are needed to show more accurate conclusions. Level of
