Clinical study on removal timing of drainage tube,changes of local skin temperature and soft tissue swelling after total knee arthroplasty
Objective:To explore the effects of drainage tube removal timing on changes of local skin temperature and soft tissue swelling after total knee arthroplasty(TKA).Methods:A total of 90 patients with osteoarthritis admitted to the hospital were enrolled as the research objects between March and October 2023.According to removal timing of drainage tube,they were divided into control group(24 hours after TKA)and study group(48 hours after TKA),45 cases in each group.The differences in postoperative drainage volume,skin temperature,postoperative circumference of limb swelling and joint function[Knee society score(KSS)]between the two groups were compared.Results:At 48 hours after surgery,total drainage volume in study group was more than that in control group(P<0.05).Compared with that at 1day after surgery,skin temperature was decreased in both groups at 7 days and 14 days after surgery.At 7 days and 14 days after surgery,skin temperature in study group was lower than that in control group(P<0.05).At 7 days after surgery,circumference of limb swelling was significantly increased in both groups,and which at 14 days after surgery was lower than that at 7 days after surgery.At 7 days and 14 days after surgery,circumference of limb swelling in study group was lower than that in control group(P<0.05).At 1 month after surgery,KSS was increased in both groups,and which was higher in study group than control group(P<0.05).Conclusion:Compared with 24 hours after TKA,removal of drainage tube at 48 hours after TKA is more beneficial to reduce local skin temperature and soft tissue swelling,and promote recovery of joint function in patients with osteoarthritis.
