Abstract Background This study aimed to assess whether use of continuous passive motion (CPM) could improve range of motion in patients after total knee arthroplasty (TKA), if it could affect the surgical wound aspect (SWA) and if it could influence on pain management after TKA. Methods We randomized 210 patients in two groups, 102 patients in the CPM group, who received a standard rehabilitation protocol together with CPM application; and 108 patients in the no-CPM group, without CPM. Variables as knee motion (flexion, extension, range of motion) and pain were measured before surgery, on the 1st, 2nd and 3rd postoperative day, and in the 2nd, 6th, 12th and 24th postoperative weeks following TKA. The SWA was determined by the “surgical wound aspect score” (SWAS) in the next 48 h after surgery. This scale analyzes swelling, erythema, hematoma, blood drainage and blisters. Results There was an improvement in the knee motion over the course of follow-up in both groups, without significant difference in flexion parameter. We found no significant differences in the total score of SWA, except for hematoma, with less severity in the CPM group. Furthermore, we found no differences in the others SWAS parameters and pain. Conclusions The application of CPM does not provide benefit to our patients undergoing TKA in terms of either improved flexion mobility or decreased pain. No relationship was found between the use of CPM and the global score of SWA following a TKA, except for a decrease in hematoma appearance.

Abstract Background. This study aimed to assess whether use of continuous passive motion (CPM) can improve range of motion in patients after total knee arthroplasty (TKA). Moreover, the relationship between the use of CPM with the surgical wound aspect (SWA) and pain management after TKA was analysed.Methods. We randomized 210 patients, 102 patients in the CPM group, who received a standard rehabilitation protocol together with CPM application; and 108 patients in the no-CPM group, without CPM. Variables as knee motion (flexion, extension, range of motion) and pain was measured before surgery, on the 1s, 2nd and 3rd postoperative day, and in the 2nd, 6th, 12th and 24th postoperative weeks following TKA. The SWA was determined by the “surgical wound aspect score” (SWAS) in the next 48 hours after surgery. This scale analyses swelling, erythema, haematoma, blood drainage and blisters. Results. There was an improvement in the knee motion over the course of follow-up in both groups, without significant difference in flexion parameter.

Abstract Background: Cryotherapy and continuous passive motion (CPM) are commonly used for conventional total knee arthroplasty (TKA) to reduce postoperative pain and increase of the range of motion (ROM). However, this postoperative nursing intervention remains elusive for patients undergoing computer-assisted total knee arthroplasty (CAS-TKA) Methods: A prospective, randomized controlled trial with a purposive sampling method was utilized. Sixty patients scheduled for a unilateral CAS-TKA at a medical center were randomly assigned to the intervention group (n=30) and control group (n=30). The intervention group applied programed cryotherapy and CPM within one hour while returning to the ward on the day of surgery, while the control group did not. Data were analyzed using mixed models to compare numeric rating scale (NRS) for pain, ROM, and swelling at postoperative day (POD) 4. Results: There was no significant difference in the NRS score between the groups ( p = 0.168). The intervention group had significantly higher ROM than the control group (98 degrees vs. 91 degrees, p = 0.004) at POD 4. Although no significant difference in joint swelling was found between groups ( p = 0.157), the intervention group had lower mean joint swelling (32.2 cm) than the control group (33.9 cm). Conclusions: Programmed cryotherapy and continuous passive motion can improve the range of motion after CAS-TKA. It should be incorporated into the daily nursing plan for patients undergoing CAS-TKA.

Abstract Background: The postoperative nursing intervention with immediate cryotherapy and continuous passive motion (CPM) remains elusive regarding the postoperative pain and range of motion (ROM) for patients undergoing computer-assisted total knee arthroplasty (CAS-TKA).Methods: A prospective, randomized controlled trial with a purposive sampling method was utilized. Sixty patients scheduled for a unilateral CAS-TKA at a medical center were randomly assigned to the intervention group (n=30) and control group (n=30).

Although no significant difference in joint swelling was found between groups (p = 0.157), the intervention group had lower mean joint swelling (32.2 cm) than the control group (33.9 cm).Conclusions: Immediate programmed cryotherapy and continuous passive motion could help to improve ROM quickly after CAS-TKA. It should be incorporated into the daily nursing plan for patients undergoing CAS-TKA.Keywords: Postoperative nursing intervention, total knee arthroplasty, continuous passive motion, cryotherapy, computer-assistedTrial registration: ClinicalTrials.gov: NCT04136431.
