These are complex injuries with very high complication rates. It has been estimated that the incidence of femoral periprosthetic fractures after T.K.A. ranged between 0,3 to 2,5%, but increases up to 38% when considering revision T.K.A. Patient-related risk factors for T.K.A. periprosthetic fracture (T.K.A.P.F.) include osteoporosis, age, female sex, revision arthroplasty and peri-implant osteolysis. The grate debate concerns the choice of the most appropriate fixation device for T.K.A.P.F.: closed or open reduction with internal fixation with either locked plate or intramedullary nail is the most commonly used for treating these fractures. Success of these methods depends on the fracture pattern, the stability of implants, and the patient\u2019s bone quality which is often poor in elderly, thus resulting in high complication rates. Conversely, a revision of T.K.A. (R.T.K.A.) should be considered in case of prosthetic component instability, severe comminution or metaphyseal extension of the fracture (that precludes a good fixation), previous treatments failure and severe malalignment of T.K.A. Instead megaprosthesis and allograft-prosthesis composite are necessary in case of sever bone loss. Considering the variability of the clinical scenario of T.K.A.P.F., this complex injury requires and experienced and comprehensive approach based on both facture fixation and\/or revision arthroplasty.<\/jats:p>","DOI":"10.52965\/001c.38566","type":"journal-article","created":{"date-parts":[[2022,10,13]],"date-time":"2022-10-13T02:12:27Z","timestamp":1665627147000},"source":"Crossref","is-referenced-by-count":7,"title":["KNEE PERIPROSTHETIC FRACTURES IN THE ELDERLY: CURRENT CONCEPT"],"prefix":"10.52965","volume":"14","author":[{"given":"Achille","family":"Pellegrino","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Traumatology , \u201cS.
