“Postoperative cryotherapy is a potentially simple, noninvasive option and beneficial for the reduction of reducing pain, bleeding, length of stay, analgesic requirement and swelling after total knee arthroplasty. Moreover, there was no early or late prosthesis infection in cryotherapy groups, which may be considered as an additional measure to prevent prosthesis infection.”

• Patients using cTreatment have less swelling of the knee joint compared to patients using a cold pack. A statistically significant difference (p-value 0,003) is found for the patella upper end diameter.

• Patients using a cTreatment have higher haemoglobin levels compared to patients using a cold pack. A statistically significant difference (p-value <0,001) is found for Hb levels.

• Patients using cTreatment have lower knee temperature compared to patients using a gel pack. A statistically significant difference (p-value <0,001) is found for temperature.

• Patients using cTreatment have lower VAS+ pain scores compared to using a gel pack. A statistically significant difference (p-value <0,001) is found for Vas pain scores.

• Patients using cTreatment pre- & post-operative show 117% change in knee flexion (°) compared to a gel pack. Furthermore Patients using cTreatment pre- & post op. show 114% change in knee flexion (°) compared to only using cTreatment post op. A statistically significant difference (p-value <0,001) is found for knee flexion (°).
