The study group underwent preoperative risk stratification using a predictive model (low, medium, high) and received individualized, stepwise rehabilitation training based on daily activity load monitored via wearable devices; the control group followed a standardized, uniform rehabilitation protocol. Primary outcome measures included Visual Analog Scale (VAS) scores preoperatively and postoperatively at 1 day, 3 days, 1 month, 3 months, and 6 months. HSS scores were used for TKA patients and Harris scores for THA patients. Generalized estimating equations were applied to adjust for baseline confounding factors. Incidences of deep vein thrombosis (DVT) and surgical site infection (SSI) were also recorded.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      After adjusting for baseline confounders, the intervention group had significantly lower VAS pain scores across all postoperative follow-up time points (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05).

A prominent functional improvement trend was observed, especially during the critical early rehabilitation window at 1-month post-arthroplasty. The intergroup differences in both HSS and Harris Hip scores peaked at 3 months postoperatively.
