Cryocompression versus icepacks after total knee replacement
Official title: Monocentric Randomised Controlled Trial Assessing Cryocompression Following Total Knee Replacement
Run by Clinique des Cèdres · NCT07366736 · Data updated 2026-11-12
This trial will test whether using a cryocompression device (Game Ready) after primary total knee replacement reduces pain, swelling, and opioid use in adult patients.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older scheduled for primary unilateral total knee replacement with BMI under 40, able to consent and communicate in French, and affiliated with a French social security scheme are ideal candidates.
✕Probably not a fit
Patients having revision or bilateral knee replacements, those who are pregnant or breastfeeding, with BMI ≥40, or unable to comply with study procedures or to communicate in French are unlikely to qualify or benefit.

What this trial studies
This monocentric randomized controlled trial will compare postoperative cryocompression using a Game Ready device to standard icepacks in adults having primary total knee replacement. Participants who meet inclusion criteria will be randomized and receive the assigned cold therapy after surgery, with teams recording pain on a visual analogue scale, range of motion, knee circumference, and opioid consumption. The trial builds on a small RCT by Marinova et al. that found only short-term improvement in extension range of motion, so this study aims to provide more definitive data with fewer losses to follow-up. The study is conducted at Clinique des Cèdres in Échirolles and requires on-site visits and French-language communication.
Why it matters
Potential benefit: If successful, cryocompression could reduce post-operative pain, swelling, and opioid use, helping patients recover faster with less medication.
How similar studies have gone: Previous small trials, including Marinova et al., showed limited short-term benefit (improved extension ROM) but were underpowered and had follow-up losses, so cryocompression remains promising but not conclusively proven.
