Ankle sprain:
what the guidelines actually recommend

What matters is what comes next

The lateral ankle sprain is one of the most common musculoskeletal presentations and one of the most casually treated. The clinical stake lies in residual instability and recurrence, far more than in the acute episode itself.

The guidelines are clear on two points. First, the severity of the ligament damage is assessed more reliably by a delayed physical examination, four to five days after the trauma, than in the hour that follows¹. Second, after an acute lateral ligament rupture, it is the combination of a functional support, tape or a brace, with an exercise programme that gives the best outcome¹.

A short period of immobilisation may relieve pain and swelling without constituting the treatment. And a brace remains an efficacious option to prevent recurrence on return to sport¹.

On cold in the sprain itself, the honest position fits in one sentence: the guidelines list it among the modalities supported well enough for the acute phase², the direct randomised evidence remains thin³, and two large trials are currently running to settle the question. In the meantime, its role is to control pain and swelling so that weight bearing and exercise can start sooner. It is the exercise programme that restores functional stability, not the cold.

After ankle surgery, the data is clearer

This is the other half of the subject, and the one where the evidence exists.

A systematic review published in 2025, devoted to joints other than the knee, gathered four studies and 301 patients on the operated foot and ankle⁴. Its conclusion on that segment: cryotherapy brings a benefit on pain and on analgesic consumption.

The same review adds a nuance that is in fact the main argument. On oedema, cryotherapy alone is not the most effective method: the authors conclude that an approach combining cold, compression and elevation is the one that performs best on swelling⁴.

That is precisely the definition of a cryocompression session with the leg raised. Cold addresses the pain, dynamic compression drains the fluid that has collected, and elevation stops it running back down. On an ankle, where swelling is the number one limiting factor and where gravity works against drainage continuously, the three together are what makes weight bearing possible again.

The protocol in practice

Leg raised during the session, ideally above heart level: on an ankle, elevation is part of the treatment, not part of the comfort.

In the first week, sessions are spread through the day, independently of physiotherapy. After that they come to frame it, before to mobilise a joint that hurts less, and after to contain the response to the effort. And occasionally beyond that, after a day on the feet or a longer walk.

Precautions. The wrap goes over a watertight dressing. Monitor the skin and shorten sessions as long as skin sensation has not returned after a block. In peripheral vascular disease or neuropathy, check with the prescribing clinician first.

Kolde at the patient's home

Kolde rents the Game Ready® GRPro 2.1 with the anatomical ankle wrap directly to the patient's home, with delivery, set-up and a hands-on walkthrough by a member of the team, and support reachable at any hour. On an ankle, cold and compression only count if the leg is raised during the session⁴. That is the first point the team demonstrates at set-up, and the one that changes the result most.
