Early postoperative gait performance remains poorly understood, particularly regarding differences between surgical treatments, such as proximal femur nailing and hemiarthroplasty. Identifying gait alterations early in rehabilitation could optimize clinical interventions. This prospective observational cohort study included 40 elderly patients hospitalized after acute hip fracture surgery. Relative peak force and step duration were assessed using the ambulant pressure biofeedback system during postoperative mobilization. Additionally, three-dimensional gait analysis evaluated spatiotemporal parameters and sagittal plane kinematics of the hip, knee, and ankle. Results demonstrated significant improvements in median peak force (45.32% to 70.00%, (p &lt; 0.001)) and median step duration (2.96 s to 137 s, (p &lt; 0.001)) at the end of the hospitalization period. No significant differences in step duration and peak force were observed between the different surgical procedures, proximal femur nail, and hemiarthroplasty. Three-dimensional gait analysis showed significantly reduced hip extension during terminal stance in the operated leg compared to the healthy leg. These findings highlight the utility of biofeedback systems for monitoring early rehabilitation progress and emphasize the importance of 3D gait analysis in identifying early postoperative gait deficits. Targeted interventions during hospitalization could enhance functional recovery and improve patient outcomes.<\/jats:p>","DOI":"10.3390\/s25061888","type":"journal-article","created":{"date-parts":[[2025,3,18]],"date-time":"2025-03-18T11:02:31Z","timestamp":1742295751000},"page":"1888","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Early Postoperative Gait Analysis in Elderly Patients Following Hip Fracture Surgery"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1355-3170","authenticated-orcid":false,"given":"Gereon Anton","family":"Hecht","sequence":"first","affiliation":[{"name":"Department of Trauma Surgery, Maastricht University Medical Centre (MUMC+), 6229 HX Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9463-5749","authenticated-orcid":false,"given":"Rachel","family":"Senden","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Maastricht University Medical Centre (MUMC+), 6229 HX Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4819-4863","authenticated-orcid":false,"given":"Rik","family":"Marcellis","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Maastricht University Medical Centre (MUMC+), 6229 HX Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Mertes","sequence":"additional","affiliation":[{"name":"Department of Trauma Surgery, Maastricht University Medical Centre (MUMC+), 6229 HX Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Willems","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Movement Sciences, Maastricht University, 6211 LK Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8236-8754","authenticated-orcid":false,"given":"Kenneth","family":"Meijer","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Movement Sciences, Maastricht University, 6211 LK Maastricht, The Netherlands"},{"name":"School of Nutrition and Translational Research in Metabolism (NUTRIM), Maastricht University, 6211 LK Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5005-1285","authenticated-orcid":false,"given":"Martijn","family":"Poeze","sequence":"additional","affiliation":[{"name":"Department of Trauma Surgery, Maastricht University Medical Centre (MUMC+), 6229 HX Maastricht, The Netherlands"},{"name":"School of Nutrition and Translational Research in Metabolism (NUTRIM), Maastricht University, 6211 LK Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3601-3458","authenticated-orcid":false,"given":"Taco J.","family":"Blokhuis","sequence":"additional","affiliation":[{"name":"Department of Trauma Surgery, Maastricht University Medical Centre (MUMC+), 6229 HX Maastricht, The Netherlands"},{"name":"School of Nutrition and Translational Research in Metabolism (NUTRIM), Maastricht University, 6211 LK Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1093\/bmb\/ldv036","article-title":"Management of hip fracture","volume":"115","author":"Fernandez","year":"2015","journal-title":"Br.
