Comparison of gaseous cryotherapy with more traditional forms of cryotherapy following total knee arthroplasty.

Objective: The aim of this study was to assess the efficacy of gaseous cryotherapy following total knee arthroplasty (TKA) and to compare it to routinely used strategies for applying cold therapy.

Patients And Methods: Sixty-six patients undergoing primary unilateral TKA were randomized into three groups and received "gaseous cryotherapy (GC)", "cold pack" and "cryocuff" applications, respectively throughout the hospital stay. Primary outcomes (knee pain intensity, mobility and girth measurements) were recorded on preoperative day 1 as well as on postoperative day (POD) 7.
