Application and efficacy analysis of common rehabilitation devices used after knee replacement surgery
This review systematically summarizes the common rehabilitation devices used in postoperative rehabilitation of knee replacement and their roles at different stages of recovery.Knee replacement is a primary treatment for knee osteoarthritis,and postoperative rehabilitation is crucial for functional recovery and improvement in patients'quality of life.Based on the different stages of rehabilitation,the goals are categorized into pain relief and swelling reduction,restoration of joint mobility,strengthening of muscle power,and improvement of gait and balance.This paper provides a detailed overview of the commonly used medical devices at each stage,such as cold therapy devices,patient-con-trolled analgesia pumps,continuous passive motion machines,transcutaneous electrical nerve stimulation devices,neuromuscular electrical stimulation devices,and gait training equipment.Although the efficacy of some devices remains controversial,particularly in pain management and joint mobility restoration,they have demonstrated positive effects in accelerating postoperative recovery and enhancing patient satisfaction.With the promising prospects of virtual reality and robot-assisted rehabilitation devices,future personalized rehabilitation plans are expected to further optimize the recovery experience and outcomes for patients.
