The effect of enhanced recovery protocols on postoperative rehabilitation in orthopedic surgery patients.

Orthopedics is a critical hospital department that has experienced shifts in the spectrum of orthopedic conditions due to societal advancements in recent years. While surgical interventions are effective in restoring fracture function, perioperative care remains a key factor in optimizing patient recovery. This study aims to assess the impact of orthopedic rehabilitation care based on the enhanced recovery after surgery (ERAS) protocol on postoperative rehabilitation.
