Osteoporosis is a systemic skeletal disease caused by an imbalance between bone resorption and formation. Current treatments primarily involve medication hormone therapy. However, these lack directionality are often ineffective for locally severe osteoporosis, with the potential complex adverse reactions. Consequently, treatment strategies using bioactive materials or external interventions have emerged as most promising approaches. This review proposes twelve microenvironmental targets osteoporosis-related pathological changes, including local accumulation of inflammatory factors reactive oxygen species (ROS), mitochondrial dynamics, insulin resistance, disruption cell autophagy, apoptosis, changes in neural secretions, aging cells, increased tissue vascular destruction, decreased regeneration. Additionally, this examines current research status effective biophysical biochemical stimuli based on summarizes advantages optimal parameters different bioengineering to support preclinical clinical osteoporosis Finally, addresses ongoing challenges future prospects.
