Brief Summary

The purpose of this prospective crossover study is to determine if noninferiority exists in the use of the Thermazone cryotherapy machine when compared to Breg Polarcare, the current standard-of-care cryotherapy machine, for control of pain and reduction in postoperative narcotic medication consumption following arthroscopic rotator cuff repair surgery. Specifically, the investigators propose to test the hypothesis that in adults having arthroscopic rotator cuff repairs, the Thermazone device is non-inferior to Breg Polarcare on postoperative pain and opioid use over the initial 8 postoperative days.

Detailed Description

Cryotherapy has traditionally been used for the acute treatment of musculoskeletal injuries and following operative procedures. Cryotherapy currently represents the standard of care following common orthopaedic procedures to the knee and shoulder. In addition to relieving pain and swelling during the acute inflammatory period following surgery, cryotherapy has also been shown to reduce muscle spasms, promoting quicker functional recovery, accelerating post-operative rehabilitation and return to regular activities. Multiple investigations have demonstrated the benefit of cryotherapy following both shoulder and knee surgeries when compared to ice alone or no cryotherapy, however conflicting data prevents consensual agreement regarding the success of cryotherapy when compared to other post-operative pain control modalities.

The use of cryotherapy has been extensively studied in the shoulder following operative procedures. Kraeutler et al. compared compressive cryotherapy versus ice alone, reporting no reduction in pain between the two modalities following arthroscopic rotator cuff repair or subacromial decompression. Singh et al. reported in their randomized controlled trial that patients undergoing arthroscopic procedures to the shoulder reported lower pain intensity on Days 1, 14 and 21 with the use of cryotherapy compared to patients in the non-cryotherapy group. Meanwhile, Speer et al. found in their prospective study that use of cryotherapy in the post-operative period was associated with reduced pain and swelling, decreased opioid use and better sleep quality following arthroscopic rotator cuff repair.

Similar results have been reported in patients treated with cryotherapy following anterior cruciate ligament reconstruction. Seacrist et al. performed a systematic review, identifying 10 randomized controlled trials investigating the effects of cryotherapy/compression on pain management following anterior cruciate ligament reconstruction. Cryotherapy was found to improve analgesia compared to patients treated without cryotherapy in 4 trials, while in 4 trials ice water and water at room temperature provided equivalent analgesic effects. Raynor et al. found in their meta-analysis that cryotherapy following anterior cruciate ligament reconstruction significantly improved post-operative pain control, while no improvements in postoperative range of motion or drainage were appreciated. Meanwhile, a combined cryotherapy-compression device was found to result in a significantly higher percentage of patients discontinuing narcotics 6 weeks post-operatively with a significantly greater decrease in VAS scores from pre-operative levels at 2 and 6 weeks post-operatively when compared to ice packs alone.

Adverse reactions to cryotherapy including frostbite, cutaneous necrosis and neuropathy are rare, but have been reported, necessitating the need for appropriate use guidelines, recognition and prevention.

As such, despite multiple studies examining the post-operative impact of cryotherapy following shoulder and knee procedures, no definitive conclusions on the effectiveness of cryotherapy on outcomes related to the use of post-operative analgesic medication, pain control, functional outcomes and range of motion have been determined. The conflicting reports regarding the benefit of cryotherapy may be related to the failure to achieve required decreases in intra-articular temperatures. Additional investigations are needed to better understand the impact of cryotherapy following arthroscopic rotator cuff, shoulder labral repair, anterior cruciate ligament reconstruction and meniscal repair/resection procedures.

Breg polarcare is a commonly used cryotherapy device that has a variety of clinical applications. The polarcare device requires ice and water, which is then circulated through a pad which the patient applies directly to the affected area. The Thermazone device does not require the use of ice and allows for osscilation between hot and cold temperatures. Currently, both cryotherapy devices are approved for use following surgery. However, no study to date has compared the Breg polarcare and thermazone devices in the context of arthroscopic rotator cuff surgery.

Arm && Interventions

Group	Intervention	Description
Breg Polarcare	Breg Polarcare	Patients within the Breg Polarcare treatment arm will use the Breg Polarcare device for the first two days post-operatively following their arthroscopic rotator cuff repair. They will switch to the Thermazone device for post-operative days 3 and 4. They will continue to alternate every two days for 8 days total post-operatively.
Thermazone	Thermazone	Patients within the Thermazone treatment arm will use the Thermazone device for the first two days post-operatively following their arthroscopic rotator cuff repair. They will switch to the Breg Polarcare device for post-operative days 3 and 4. They will continue to alternate every two days for 8 days total post-operatively.
Breg Polarcare	Thermazone	Patients within the Breg Polarcare treatment arm will use the Breg Polarcare device for the first two days post-operatively following their arthroscopic rotator cuff repair. They will switch to the Thermazone device for post-operative days 3 and 4. They will continue to alternate every two days for 8 days total post-operatively.
Thermazone	Breg Polarcare	Patients within the Thermazone treatment arm will use the Thermazone device for the first two days post-operatively following their arthroscopic rotator cuff repair. They will switch to the Breg Polarcare device for post-operative days 3 and 4. They will continue to alternate every two days for 8 days total post-operatively.

Primary Outcome Measures

Name	Time	Method
Simple Shoulder Test (SST)	6 weeks post-operatively	Scale ranges from 0% to 100% with higher scores representing better outcomes. Consists of a series of 12 "yes" or "no" questions the patient answers about the function of the involved shoulder. The answers to these questions provides a standardized way of recording the function of a shoulder before and after treatment.
Pain Visual Analog Scale	6 weeks post-operatively	Scale from 0 to 10; 0 represents no pain and 10 represents the most amount of pain.
American Shoulder and Elbow Surgeons (ASES) Score	6 weeks post-operatively	Scale from 0 to 100 with higher scores representing better outcomes. The total score is weighted 50% for pain and 50% for function.

Secondary Outcome Measures

Name	Time	Method
Adverse reactions from cryotherapy devices	6 weeks post-operatively	The investigators will assess the rate of adverse reactions from the two cryotherapy devices and develop and adverse reaction profile.
