  • The Efficacy of Combined Cryotherapy and Compression Compared to Cryotherapy Alone Following Anterior Cruciate Ligament Reconstruction. Brian R. Waterman, CPT, MC et al. Presented at American Academy of Orthopaedic Surgeons, Annual Meeting 2011.

“In the current study, patients undergoing ACL reconstruction with postoperative compressive cryotherapy had improved pain relief and earlier discontinuation of narcotic pain medication.”

A randomized, prospective clinical trial was conducted to evaluate the effectiveness of cryotherapy with or without intermittent pneumatic compression after arthroscopic ACL reconstruction comparing Game Ready® and conventional ice pack therapy at preoperative, 1 week, 2 weeks and 6 weeks postoperative. All patients were required to use cryotherapy at least 3x30 minutes daily. Compliance, usage of pain medications and VAS scores, swelling (girth) and quality of life and knee scores were measured.

“During weeks 1 and 2, patients with compressive cryotherapy had 100% (n=18) compliance with use compared with 83% (n=18) of the control group (p=0.23).”

“At 6 weeks postoperatively, 15 of 18 (83.3%) of all patients in the compressive cryotherapy group had discontinued use of all pain medication, compared with 5 of 18 patients (27.8%) control group (p=0.0008).”


  • A comparison of intramuscular temperature of the thigh during treatments with the Grimm CRYOpress and the Game Ready Accelerated Recovery System. Seamon CL, Merrick MA. J Athletic Training 40(2): S99, 2005.

"The smaller and portable Game Ready System may be used instead of the larger CRYOpressTM for effective cold-compression therapy".

The purpose of this study was to describe and compare the intramuscular temperature change of the anterior  thigh for each device. Design and Settings: A 2X2 factorial  design with repeated measures on both independent variables (treatment & measurement depth)  was used. In this study, skin and intramuscular temperature were measured at 30 second intervals during baseline and treatment  periods. “The principal conclusion is that  the smaller, portable Game ReadyTM device can be used instead of a larger, less portable CRYOpressTM without  compromising the thermal effectiveness of the treatment”.


  • Active Cooling and Intermittent Pneumatic Compression Device vs. Standard Cold Therapy after Knee Arthroscopy Goradia, V. K., MD, Warnock, N., MD, MBA (2007): Presented at Arthroscopy Association of North America April 2007.

"Following knee arthroscopy, an active cooling and compression device showed improved range of motion at 2 and 4 weeks postoperatively compared to standard cold therapy".

A single-center, prospective randomized clinical trial was conducted at a sports medicine clinic. Forty patients were randomized to receive either Game Ready (GR) or DuraKold (DK) after undergoing knee arthroscopy (KA) with partial meniscectomy and/or chondroplasty.   Patients with grade N chondromalacia or those receiving other treatment were excluded. Clinical measurements included knee girth, active flexion, and active extension. Pain was measured using a self-reported Visual Analogue Scale (VAS).

“Following knee arthroscopy, an active cooling and compression device showed improved  range of motion at 2 and 4 weeks postoperatively compared  to standard cold therapy.  Reduction in swelling and pain were comparable between treatment groups”.


  • Effects of Continuous Circulating Water and Cyclical Compression on Intramuscular and Surface Temperatures. Womochel, K.S., Trowbridge, C.A., and Davis, D.R., Southwest Athletic Trainers’ Association Annual Meeting. Arlington, TX, July 2007.

A study of the effects of continuous circulating water and cyclical compression on muscle and skin temperature in the distal quadriceps after a 30 minute treatment and 30 minute re-warming in sixteen healthy volunteers showed “Game Ready with (cyclic) compression seem(ed) to have a greater magnitude and longer duration of cooling than PolarCare”.

 The purpose of this study was to investigate the effects of continuous circulating water and compression  on muscle and skin temperature in the distal quadriceps after a 30 minute treatment and 30 minute re-warming. At the Exercise Science Research Laboratories at the University of Texas at Arlington a thermocouple inserted 1.5 cm below subcutaneous adipose tissue in healthy subjects.  During treatments, intramuscular temperature was sampled and a skin thermocouple sampled surface temperature. Visual analog scales (VAS) were used to record patients' perceived sensations (0=no cold & 10=very cold) at 5-minute intervals.

 “Game Ready with (cyclic) compression  seem(ed) to have a greater magnitude  and longer duration of cooling than PolarCare.
