RESUMO
OBJECTIVE: To analyze the clinical, quality of life, and healthcare quality outcomes obtained in a series of patients undergoing total hip arthroplasty (THA), who were empowered and monitored using the AVIP application. These results will be compared with a control group followed through a standard protocol. MATERIAL AND METHOD: Randomized clinical trial with parallel groups involving patients with an indication for THA. Clinical variables were measured and compared using the WOMAC and mHHS, pain assessed by the VAS, quality of life with the SF-12 test. Walking capabilities were analyzed using the Functional Gait Assessment Scale, along with satisfaction levels assessed through the SUCE questionnaire, and perceived anxiety levels related to the process. RESULTS: A total of 68 patients were evaluated, with 31 patients in the AVIP group and 33 in the Control group completing the follow-up. Both groups demonstrated improvement in clinical outcomes based on the WOMAC and mHHS hip tests, a reduction in perceived pain, and an enhancement in quality of life according to the SF-12 test. Patients in the AVIP study group exhibited non-inferiority in clinical outcomes and satisfaction compared to the control group, as well as lower anxiety levels and improved walking capabilities after the first month of follow-up. Notably, 82.25% of the follow-up visits for this group were conducted remotely. CONCLUSION: The implementation of a mHealth application like AVIP can be safely offered to selected patients undergoing hip arthroplasty, enabling effective monitoring and providing continuous information and training.
RESUMO
INTRODUCTION: Loss of bone stock and anatomical alteration of the proximal femur make femoral revision surgery a complex procedure in which the choice of implant will be critical. Our goal is to assess the clinical and radiological results of complete coating Monoblock stems. MATERIAL AND METHODS: Retrospective study of 78 consecutive cases of femoral review surgery intervened by our unit. RESULTS: The average follow-up was 122 months. The average score on the Harris Hip Score was 81.2 ± 11.4 points. An age of less than 65 years, a minor femoral defect according to Paprosky classification (I, II and IIIA), the existence of a single previous surgery and the non-occurrence of intra or postoperative complications, was associated with better clinical and functional outcomes (p < 0.05).Cumulative survival was 96.7% at age 10 if we consider as failure the removal of the stem by aseptic loosening and 92% if we consider withdrawal for any cause to fail. CONCLUSION: Despite the current tendency to use modularity in femoral review surgery and given the results presented, we consider that complete coating monoblock stems provide a firm and stable fixation. However, the worst results in patients with major defects have led to other options being considered.
INTRODUCCIÓN: La pérdida de stock óseo y la alteración anatómica del fémur proximal hacen de la cirugía de revisión femoral un procedimiento complejo en la que la elección del implante será fundamental. Nuestro objetivo es valorar los resultados clínicos y radiológicos de los vástagos monobloque de recubrimiento completo. MATERIAL Y MÉTODOS: Estudio retrospectivo de 78 casos consecutivos de cirugía de revisión femoral intervenidos por nuestra unidad. RESULTADOS: El seguimiento medio fue de 122 meses. La puntuación media en la escala de Harris Hip Score fue de 81.2 ± 11.4 puntos. Una edad menor de 65 años, un defecto femoral menor según la clasificación de Paprosky (I, II y IIIA), la existencia de una única cirugía previa y la no aparición de complicaciones intraoperatorias o postoperatorias se asoció con mejores resultados clínicos y funcionales (p < 0.05). La supervivencia acumulada fue de 96.7% a los 10 años si consideramos como fracaso la retirada del vástago por aflojamiento aséptico y de 92% si consideramos como fracaso la retirada por cualquier causa. CONCLUSIÓN: Pese a la tendencia actual al uso de la modularidad en cirugía de revisión femoral y dados los resultados presentados, consideramos que los vástagos monobloque de recubrimiento completo proporcionan una fijación firme y estable. Sin embargo, los peores resultados obtenidos en pacientes con defectos óseos mayores han provocado que se valore otro tipo de opciones.
