Le procedure vengono eseguite utilizzando il sistema di Lipogems.

Tutte le procedure eseguite negli studi che coinvolgono i partecipanti umani erano in conformità con gli standard etici del Comitato di ricerca istituzionali e/o nazionali e con la dichiarazione di Helsinki del 1964 e sue successive modifiche o etici comparabili standard.

Negli ultimi anni, studi clinici e preclinici hanno concentrato la loro attenzione sull'effetto di CSTA per trattare diverse patologie muscolo-scheletriche. Lo scopo di questo articolo è di descrivere il protocollo per il trattamento delle lesioni osteocondrali dell'astragalo utilizzando microfratturate e tessuto adiposo purificato in associazione con microperforazioni artroscopica. Il protocollo prevede diversi passaggi critici con elevati rischi di complicazioni. Durante la raccolta del grasso, complicazioni possono e...

L'artroscopia è il gold standard per il trattamento delle lesioni osteocondrali dell'astragalo (OLTs) con l'obiettivo di alleviare il dolore, ripristino della funzionalità e migliorare la qualità della vita, soprattutto in pazienti giovani e attivi.
Attualmente, le tecniche artroscopiche possono essere classificate in tre modi. La tecnica riparativa stimola le cellule derivate dal midollo osseo attraverso un microperforazioni a livello della lesione e di sbrigliamento. La tecnica ricostruttiva sostituisce la lesione usando un innesto autologo o eterologo ostechondral. La tecnica rigenerativa sfrutta la capacità delle cellule multipotenti per differenziare e replicare per ricostruire il tessuto danneggiato1,2,3,4,5,6 .
Negli ultimi anni, tecniche rigenerative sono stati oggetto di numerosi studi in vitro e in vivo per il trattamento di OLTs e particolarmente mesenchymal cellule staminali derivate da tessuto adiposo (CSTA)7,8 , 9. queste cellule staminali mesenchimali esibiscono caratteristiche morfologiche e funzionali simili alle altre cellule multipotenti, isolati da altri tessuti; Essi hanno anche la capacità di differenziarsi in diversi e linee cellulari differenti sia in vitro che in vivo10,11,12,13. Il focus sulla ricerca per quanto riguarda queste cellule è principalmente a causa della loro localizzazione, infatti essi rappresentano dal 10% al 30% del peso corporeo normale con una concentrazione di 5000 cellule per grammo di tessuto13,14. D'altra parte, un fattore che limita l'utilizzo di queste cellule è relativo alla loro manipolazione durante le procedure di laboratorio. Il lipoaspirato contenente aggregati di adipociti, fibre di collagene e componenti vascolari normali enzimaticamente viene elaborato con collagene di tipo I A e sottoposti ad emolisi prima cultura. L'obiettivo qui è quello di descrivere il protocollo per il trattamento delle lesioni osteocondrali dell'astragalo utilizzando microfratturate e tessuto adiposo purificato.

autologous microfractured and purified adipose tissue for arthroscopic management of osteochondral lesions of the talus

Negli ultimi anni, tecniche rigenerative sono stati sempre più studiati e usati per trattare le lesioni osteochondral del talus. In particolare, diversi studi hanno focalizzato la loro attenzione su cellule staminali mesenchimali derivate dal tessuto adiposo. Le cellule staminali adiposo-derivate (CSTA) esibiscono caratteristiche morfologiche e proprietà simili alle altre cellule mesenchimali e sono in grado di differenziarsi in diverse linee cellulari. Inoltre, queste cellule sono anche ampiamente disponibili nel tessuto sottocutaneo, che rappresentano il 10-30% del peso corporeo normale, con una concentrazione di 5000 cellule per grammo di tessuto.
La tecnica presentata, il primo passo prevede raccolta CSTA dall'addome e un processo di microfrattura e purificazione; Successivamente, la procedura chirurgica viene eseguita interamente arthroscopically, con meno dissezione dei tessuti molli, migliore visualizzazione congiunta e un recupero più veloce rispetto a procedure standard aperte. L'artroscopia è caratterizzato da una prima fase in cui la lesione è identificata, isolata e preparata con microperforazioni; la seconda fase, eseguita a secco, prevede l'iniezione di tessuto adiposo a livello della lesione.
Tra gennaio 2016 e settembre 2016, quattro pazienti hanno subito il trattamento artroscopico di lesione osteochondral del talus con microfratturate e tessuto adiposo purificato. Tutti pazienti hanno segnalato il miglioramento clinico sei mesi dopo la chirurgia senza le complicazioni segnalate. I punteggi funzionali all'ultimo follow-up sono incoraggianti e confermano che la tecnica fornisce sollievo dal dolore affidabile e miglioramenti in pazienti con lesione osteochondral del talus.
