Outcomes included operative time, fluoroscopy exposure, incision length, inflammatory markers, functional recovery, internal medicine complications, mechanical complications, hospitalization cost, and estimated carbon footprint.

Functional recovery was faster, with higher Harris Hip Scores (87.7\u2009\u00b1\u20092.7 vs. 84.7\u2009\u00b1\u20093.4) and greater hip motion. Internal medicine complications\u2014including infection, deep vein thrombosis, pulmonary embolism, and cardiovascular events\u2014were significantly reduced. Mechanical complications, including implant failure, were reported separately.
