Use of Cold and Compression Therapy With Total Knee Replacement Patients

Investigating the Use of a Cryopneumatic Therapy Device in Primary Total Knee Arthroplasty Patients

The purpose of the study is to evaluate the effectiveness of a device that delivers cold and intermittent compression as compared to ice and compressive wraps on patients who have undergone knee replacement.

The use of cryotherapy with compression for orthopedic postoperative recovery has not been fully investigated. A new device has been developed that combines cold and intermittent pneumatic compression in a single system. A well-controlled clinical study evaluating the clinical effectiveness of cryotherapy with compression in an orthopedic postoperative application is the subject of this protocol. Patients diagnosed with osteoarthritis of the knee and scheduled for primary total knee arthroplasty procedure will be invited to participate in this study.

• Physically and mentally able and willing to participate in and follow the study protocol and schedule
• Able and willing to have all postoperative physical therapy visits in a physical therapy clinic associated with the research site
• Signed informed consent document for the study

Exclusion Criteria:

• Rheumatoid arthritis

• History of thrombophlebitis in lower extremities
• An active systemic disease such as AIDS, HIV, hepatitis, etc.
• Is immunologically suppressed or has received or is receiving steroids at any dose daily for more than one month within the last 12 months
• Is pregnant or planning to become pregnant during the study period
