The effect of cryogenics physics for patients after total knee arthroplasty

Objective: To investigate the effect of cryogenics physical therapy on postoperative patients with knee replacement surgery. Methods: From December 2012 to December 2013,121 patients diagnosed as knee osteoarthritis were recruited in this study. Patients from June 2013 to December 2013,60 cases as the observation group,and patients from December 2012 to May 2013,61 cases as the control group. All of the patients received unilateral total knee arthroplasty( TKA),and different types of ice therapies were performed according to the group. The observation group received continuous ice therapy temperature was maintained at 0-4 ℃ for 48 h with Cry / Cuff system after operation,while the control group received intermittent ice therapy for 1 hour each time,6 times per day for 2 days. Clinical evaluation for pain( VAS),swelling and drainage volume were performed. Results: The degree of pain at different time points after the observation group were lower than the control group,there was no interaction with the various time points. The degree of swelling at different time points after the observation group were lower than the control group,the presence of interaction between the point and time. At different time points after the observation group were lower than the control group drainage,there are interactions between the point and time. Separate effects at different time points within the analysis groups,the observation group after 12 h and 24 h of drainage was statistically significant( P 0. 05),but after 24 h and 48 h of drainage no comparison statistical significance( P 0. 05); the control group after 12 h and 24 h of drainage was not statistically significant( P 0. 05),but after24 h and 48 h of drainage have more statistics significance( P 0. 05),prompt continuous drainage can end faster intra-articular effusion. Conclusion:Compared with intermittent,continuous ice therapy has the advantage of relieving post-operative pain and swelling,and reducing intra-articular bleeding,taking effect earlier.
