Impact of a new cryotherapy device on early rehabilitation after primary total knee arthroplasty (TKA): a prospective randomised controlled trial.

The aim of this prospective, randomised and single blinded study was to evaluate the efficiency and safety of a new cryotherapy device in patients undergoing unilateral, primary total knee arthroplasty (TKA). Our hypothesis was that patients administered to the new cryotherapy device would perform better than patients receiving a conventional standard cold therapy regimen.
