Medial osteoarthritis – wearing of the inside of the knee joint – can be treated with knee replacement procedures, where either part or the whole of the knee joint is replaced. For all major knee operations, post-surgery the site of operation can be painful. Increased pain may limit a patient’s progress with post-operative mobilisation. Therefore, research is already ongoing in the field of knee surgery to determine if different type of bandaging and cooling of the affected leg post-surgery may improve patient and clinical outcomes. A relatively new method is now available which involves a combination of active compression and cooling, rather than passive compression and cooling. This may reduce pain. This present study aims to assess if active compression and cooling is better than standard passive compression and cooling in terms of keeping a patient comfortable by reducing pain and possibly improving other clinical outcomes too.

This study involves a comparative evaluation of two different types of cooling therapy that is applied to the knee joint of patient who have just undergone a knee replacement operation. Straight after surgery, patients will receive either a standard cooling sleeve (cryo/cuff) or a cooling brace that also compresses (VPULSE); the latter is designed to both cool the joint and stimulate blood flow with the intermittent compression action. Pain levels are measured at various intervals and compared for the two different cooling device interventions. Other parts of the knee surgery and recovery management of patients is left unchanged.


Patients aged 18 years or older, listed for knee arthroplasty (replacement) surgery, who in the opinion of the treating surgeon, that compression & cooling therapy may be of benefit.

You can take part if:



You may not be able to take part if:


1. Under the age of 18 years2. Unable to fully understand the consent process and provide informed consent due to either language barriers or mental capacity3. Revision of previous knee replacement or osteotomy on the index leg.4. Limited life expectancy, i.e. undergoing palliative care5. Any condition that is associated with excessive bleeding, coagulation abnormalities or any other significant haematological condition (e.g. Factor V Leiden, haemophilia).6. Cardiovascular or vascular condition that in the opinion of the treating surgeon contraindicates the use of compression bandaging, including moderate to severe peripheral arterial disease, venous leg ulcer, high dose anti-coagulant medication7. Any skin or other condition that contraindicates the use of compression and cooling therapy.8. Patients who are participating in another interventional research study involving an investigational product related to the knee procedure and its aftercare.9. The patient has concurrent (medical) conditions that in the opinion of the investigator may compromise patient safety or study objectives.10. Patient has practical or mobility issues which will prevent them from removing the device themselves

It may be the case that one type of cooling therapy, either standard or with added intermittent compression, gives a patient more pain relief than the other. No additional risks are anticipated for patients. Both devices are approved for this intended use and measures are in place to avoid too much cooling or too much compression.
