Unicompartmental knee arthroplasty: state of the art and future developments

Artroplastica monocompartimentale di ginocchio: stato dell’arte e future sviluppi

  • Published:
Archivio di Ortopedia e Reumatologia

Abstract

L’artroplastica monocompartimentale di ginocchio è un trattamento consolidato per l’osteoartrosi monocompartimentale. Gli studi clinici ne evidenziano la capacità di ripristinare la normale cinematica del ginocchio e la superiorità rispetto all’artroplastica totale in termini di durata dell’ospedalizzazione, incidenza di complicanze, rapporto costo-efficacia e mortalità. I risultati ottenuti nella pratica clinica reale appaiono tuttavia meno riproducibili e sottolineano la necessità di definire le indicazioni ottimali per questo intervento, nonché di introdurre miglioramenti nel design degli impianti, nella strumentazione e nella tecnica. In questo articolo vengono descritti brevemente lo sviluppo e i principi dell’artroplastica monocompartimentale di ginocchio; vengono discussi i fattori che influenzano i risultati clinici, in particolare le indicazioni, la tecnica chirurgica e il design degli impianti; e vengono infine presentati gli sviluppi più recenti e le prospettive future di questa tecnica.
