Autologous fat transplantation for the treatment of trapeziometacarpal joint osteoarthritis

Rhizarthrosis is a progressive and disabling pathology affecting the carpometacarpal joint. It’s very common in elderly patients and typically affects postmenopausal women. The diagnosis of rhizarthrosis is mainly made by using different physical examination tests and by evaluating the type of pain and it’s then confirmed by imaging. Over the last few years increasing attention has been devoted to the assessment of new treatment techniques for rhizarthrosis. In this context intra-articular injection of autologous fat grafting for cartilage regeneration has demonstrated promising results in experimental settings as an alternative to open surgery procedures. The aim of this study was therefore to sum up the evidences available so far on autologous fat grafting as an emerging treatment for patients affected by carpometacarpal rizarthrosis. An electronic literature research was carried out on Pubmed, Google Scholars and Cochrane Library using “fat grafting”, “fat graft”, “adipose”, “fat transfer” and “lipoaspirate” as search terms. Authors believe autologous fat grafting is an interesting technique, that hand surgeon should keep in mind especially in early stages of rhizarthrosis were pain has not been solved with non-surgical treatment.
