A Prospective, Single-Blind Randomized Controlled Trial
This white paper includes a comparison of the effects of standard cryotherapy (ice) with static compression to a cryotherapy device (Game Ready® Injury Treatment System) on the postoperative rehabilitation of total knee arthroplasty patients. This clinical trial is multi-site, prospective, randomized, and controlled. It presents a unique and robust study with substantive interim data representing treatment results from approximately 38% of an intent-to-treat subject pool of patients with osteoarthritis who were scheduled for unilateral, single-incision total knee arthroplasty (TKA). Patients were randomized to a cold and intermittent pneumatic compression test device (Game Ready® Injury Treatment System) or to ice and static compression (ice and compression bandage) and were stratified according to BMI and whether they had had a TKA on the contralateral knee.
Key findings in this clinical trial are:
Subjects using a cryotherapy device reported improved pain relief over time at both the two- and six-week follow-ups compared to control subjects.
The cryotherapy group exhibited more than
double the physical function abilities of the
control group in both the Timed Up and Go and
Six-Minute Walk Test assessments.
More subjects using the cryotherapy device were able to perform complex weight-bearing physical
activities by six weeks than were control subjects
