Abstract：BACKGROUND:Early rehabilitation training is beneficial for the functional recovery after total knee arthroplasty (TKA), and its effectiveness can be enhanced through ice compression that can partly alleviate the postoperative pain. OBJECTIVE:To explore the effect of local compression cryotherapy combined with continuous passive motion on the early functional recovery after TKA. METHODS:106 patients undergoing TKA from February 2013 to February 2015 were enrolled, and randomly divided into observation and control groups (n=53 per group) according to the admission time and simple sampling. The control group was given continuous passive motion, while the observation group was subjected to local compression cryotherapy combined with continuous passive motion. The swelling degree, visual analogue scale scores, hospital for special knee surgery scores, and efficacy were compared between two groups. RESULTS AND CONCLUSION:(1) The swelling degree and visual analogue scale scores in the observation group were significantly lower than those in the control group at 24 and 48 hours after surgery (P<0.01). (2) At 2 weeks after surgery, al indicators except muscle strength were significantly improved in both two groups (P<0.05-0.01);the pain, function, activity, stability and total scores of hospital for special surgery knee scores in the observation group were significantly higher than those in the control group, and the reduction project scores were significantly lower than those in the control group (P<0.05). (3) After followed up for 6 months, the excel ent rate of knee joint function in the observation group was significantly higher than that in the control group (87%versus 70%, P<0.05). (4) These results suggest that local compression cryotherapy combined with continuous passive motion can improve early pain and swel ing degree, and promote the functional recovery after TKA.
