Weight-bearing
Weight-bearing has been studied in 4 papers since 2018: 3 observational studies in people, 1 review; 1 in the past year. The newest paper, Mar 17, 2026: “Association of Charlson Comorbidity Index and ASA Score with Postoperative Mobility in Geriatric Hip Fracture Patients”.
“Early postoperative weight-bearing and institutional rehabilitation did not significantly alter PE incidence rates.”
None of its findings points the other way.

What did studies of Weight-bearing find?
2Studies of Weight-bearing measured 2 outcomes; the most studied are pulmonary embolism (1 study) and medial meniscus extrusion (1).

Weight-bearing was not clearly linked with pulmonary embolism in humans (post-femoral neck fracture surgery).

Weight-bearing is linked with higher medial meniscus extrusion in humans (Mean US Δ-extrusion 0.8 mm ± 0.6 mm).
“The mean US MME was 1.1 mm ± 0.5 mm in supine position and 1.9 mm ± 0.9 mm under full weight-bearing.”
