A 44 years-old male patient was scheduled for osseointegration surgery 17 years after transfemoral amputation. Gait analysis was performed through 15 wearable inertial sensors (MTw Awinda, Xsens) before surgery (patient wearing his standard socket-type prosthesis) and at 3-, 6-, and 12-month follow-ups after osseointegration. ANOVA in Statistical Parametric Mapping was used to assess the changes in amputee and sound limb hip and pelvis kinematics. The gait symmetry index progressively improved from the pre-op with socket-type (1.14) to the last follow-up (1.04). Step width after osseointegration surgery was half of the pre-op. Hip flexion-extension range significantly improved at follow-ups while frontal and transverse plane rotations decreased (p &lt; 0.001). Pelvis anteversion, obliquity, and rotation also decreased over time (p &lt; 0.001). Spatiotemporal and gait kinematics improved after osseointegration surgery. One year after surgery, symmetry indices were close to non-pathological gait and gait compensation was sensibly decreased. From a functional point of view, osseointegration surgery could be a valid solution in patients with transfemoral amputation facing issues with traditional socket-type prosthesis.<\/jats:p>","DOI":"10.3390\/s23084037","type":"journal-article","created":{"date-parts":[[2023,4,17]],"date-time":"2023-04-17T03:14:09Z","timestamp":1681701249000},"page":"4037","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Longitudinal Gait Analysis of a Transfemoral Amputee Patient: Single-Case Report from Socket-Type to Osseointegrated Prosthesis"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1761-7352","authenticated-orcid":false,"given":"Stefano","family":"Di Paolo","sequence":"first","affiliation":[{"name":"Department for Life Quality Studies, University of Bologna, 47921 Rimini, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2167-4269","authenticated-orcid":false,"given":"Giuseppe","family":"Barone","sequence":"additional","affiliation":[{"name":"Department for Life Quality Studies, University of Bologna, 47921 Rimini, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8841-056X","authenticated-orcid":false,"given":"Domenico","family":"Alesi","sequence":"additional","affiliation":[{"name":"II Orthopaedic and Traumatologic Clinic, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7330-6444","authenticated-orcid":false,"given":"Agostino Igor","family":"Mirulla","sequence":"additional","affiliation":[{"name":"Department for Life Quality Studies, University of Bologna, 47921 Rimini, Italy"},{"name":"Department of Engineering, University of Palermo, 40126 Palermo, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0732-8378","authenticated-orcid":false,"given":"Emanuele","family":"Gruppioni","sequence":"additional","affiliation":[{"name":"Istituto Nazionale Assicurazione Infortuni sul Lavoro (INAIL), Centro Protesi Inail, 40054 Vigorso di Budrio, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2941-1407","authenticated-orcid":false,"given":"Stefano","family":"Zaffagnini","sequence":"additional","affiliation":[{"name":"II Orthopaedic and Traumatologic Clinic, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4773-2300","authenticated-orcid":false,"given":"Laura","family":"Bragonzoni","sequence":"additional","affiliation":[{"name":"Department for Life Quality Studies, University of Bologna, 47921 Rimini, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"732","DOI":"10.1136\/bmj.323.7315.732","article-title":"Science, medicine, and the future: Artificial limbs","volume":"323","author":"Marks","year":"2001","journal-title":"Br.
