I de seneste år, har kliniske og prækliniske forsøg sat deres fokus på effekten af ADSCs til behandling af forskellige bevægeapparatet patologier. Formålet med denne artikel er at beskrive protokollen til behandling af osteochondral læsioner af talus ved hjælp af microfractured og renset fedtvæv i forening med artroskopisk microperforations. Protokollen indebærer flere kritiske trin med stor risiko for komplikationer. Under fedt høst, kan komplikationer opdeles i lokale eller systemiske komplikationer.
<p ...

Artroskopi er guld standard for behandling af osteochondral læsioner på talus (OLTs) med henblik på smertelindring, genskabe funktionalitet, og forbedre livskvaliteten, navnlig unge og aktive patienter.
I øjeblikket, kan artroskopisk teknikker klassificeres i tre måder. Reparative teknikken stimulerer celler stammer fra knoglemarven gennem en debridering og microperforations på niveau med læsion. Rekonstruktiv teknikken erstatter læsion ved hjælp af en autolog eller heterolog ostechondral graft. Regenerativ teknikken udnytter Multipotente celler til at differentiere og replikere evne til at rekonstruere det beskadigede væv1,2,3,4,5,6 .
I de seneste år, har regenerativ teknikker været genstand for talrige i in vitro og i vivo undersøgelser til behandling af OLTs, og især mesenkymale stamceller udvundet fra fedtvæv (ADSCs)7,8 , 9. disse mesenkymale stamceller farekategorierne i morfologiske og funktionelt svarer til andre Multipotente celler, isoleret fra andre væv; de har også evnen til at skelne mellem flere og forskellige cellulære linjer både in vitro og i vivo10,11,12,13. Fokus på forskning vedrørende disse celler er hovedsagelig på grund af deres lokalisering, faktisk de repræsenterer fra 10% til 30% af normal kropsvægt med en koncentration af 5.000 celler pr. gram væv13,14. På den anden side er en faktor, der begrænser brugen af disse celler relateret til deres håndtering under laboratorieprocedurer. Den lipoaspirate, der indeholder aggregater adipocytter, kollagen fibre og normal vaskulære komponenter er enzymatisk behandles med kollagen A type I- og underkastes hæmolyse før kultur. Målet her er at beskrive protokollen til behandling af osteochondral læsioner på talus ved hjælp af microfractured og renset fedtvæv.

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

I de seneste år, er regenerativ teknikker stadig studerede og anvendes til behandling af osteochondral læsioner på talus. Navnlig har flere undersøgelser fokuserede deres opmærksomhed på mesenkymale stamceller udvundet fra fedtvæv. Fedt-afledte stamceller (ADSCs) udviser morfologiske karakteristika og egenskaber, der svarer til andre mesenchymale celler, og er i stand til at differentiere i flere cellulære linjer. Desuden, disse celler er også almindeligt tilgængelig i det subkutane væv, der repræsenterer 10-30% af den normale kropsvægt, med en koncentration af 5.000 celler pr. gram væv.
I de præsenterede teknik indebærer det første skridt høst ADSCs fra maven og en proces med microfracture og rensning; Næste, den kirurgiske procedure er udført helt arthroscopically med mindre bløde væv dissektion, bedre fælles visualisering og en hurtigere helbredelse sammenlignet med standard åbne procedurer. Artroskopi er karakteriseret ved en første fase hvor læsion er identificeret, isoleret, og tilberedt med microperforations; det andet trin, udførte tørre, indebærer injektion af fedtvæv på niveauet af læsion.
Mellem januar 2016 og September 2016 gennemgik fire patienter artroskopisk behandling af osteochondral læsion af talus med microfractured og renset fedtvæv. Alle patienter rapporteret klinisk forbedring seks måneder efter operation med ingen rapporterede komplikationer. Funktionel score på den nyeste opfølgning er opmuntrende og bekræfte, at teknikken giver pålidelige smertelindring og forbedringer i patienter med osteochondral læsion af talus.
