Outcome of Percutaneous Osseointegrated Prostheses for Patients with Transfemoral Amputation at 5-Year Follow-Up

Osseointegrated prostheses for the rehabilitation of patients with transfemoral amputations: A prospective ten-year cohort study of patient-reported outcomes and complications

“…The present study demonstrated 83% implant survival after ten years, which is less favourable than the rate observed in the same cohort after five years (92%) [ 7 ] and on par with the survival rates reported in Chile (81% five-year) [ 29 ] and the UK (80% 12-year) [ 28 ]. In our study, four implants were removed at between five and ten years due to fatigue and fracture originating from incorporated tantalum balls in the fixture for the purpose of roentgen stereophotogrammetry analysis (RSA) [ 31 ].…”

“…(2018) [ 28 ] and Rojas et al. (2021) [ 29 ] reported similar results in OPRA-treated patients in the UK (n ​= ​13) and Chile (n ​= ​21), respectively, as in the Swedish OPRA study, i.e., robust and statistically significant improvements in all four Q-TFA scores and in part of the SF-36 scores after five years. Similarly, Reetz et al.…”

“…Nevertheless, the duration of improved PRO in these studies must be regarded as short term. To the authors’ knowledge, four studies have reported five-year HRQoL results for bone-anchored TFA prostheses [ 7 , 17 , 28 , 29 ]. Matthew et al.…”
