Belsey J, Reid A, Paine E, Faulkner J. A randomised crossover trial of five cryocompression devices' ability to reduce skin temperature of the knee. PLoS One. 2024 Jan 16;19(1):e0296634.
Design: Randomised Control Trial (RCT)
Subjects: A sample of 78 patients undergoing Total Knee Arthroplasty (TKR).
Methods: Participants were randomised into 2 groups:
• Intervention group ( Donjoy Iceman ) (n=37): Applied by the surgeon in the operating room immediately after surgery and remained in place for 48 hours. • Control group (Ice bags (n=34): Received ice bags at a frequency requested by the patient (usual care) for 48 hours. Outcomes included: Pain intensity (NPRS), passive ROM (PROM), nausea/vomiting, opioid use, blood loss, function, hospital length of stay, compliance and satisfaction.
Key message: Although there was no additional benefit of using the Donjoy Iceman over ice bags for pain reduction, TKA patients using the device were significantly more satisfied, used the device more consistently, day and night, and were more likely to recommend this method of cooling.
Results:
• No significant differences in the primary outcome (pain intensity measured via NPRS) were observed between control and intervention groups.
• However, patients in the intervention group were:
• Significantly more satisfied (8.4 vs. 6.0, p=0.002);

• Used the device significantly more consistently, day and night (85.7% vs. 29.6% and 87.6% vs. 30.8%, respectively, p<0.001);
• Significantly more likely to recommend this method of cooling (96.8% vs. 68.0%, p=0.004).
