- Brief Summary
Achieving adequate range of motion post Total Knee Arthroplasty(TKA) is an important goal for return to optimum function. Traditionally, adequate range of motion has been achieved by a combination of in-home and outpatient physical therapy. While physical therapy is successful, it has the limitation of cost and availability. As copayments rise, patients may decide that they cannot afford physical therapy, potentially compromising the outcome of their surgery and successful return to function.
It is assumed that having an easy and fun to use, patient administered, incentive device that provides accurate, quantitative flexion and extension measurements may accelerate patient mobility and return to function after TKA. The Measuring Every Day (MED) portable goniometer is commercially available and provides objective, consistent range of motion measurements that are recorded and can be sent electronically to the clinician's office potentially enabling earlier clinical or therapy adjustments or modifications to the prescribed therapy.
Goniometry is a commonly used tool to measure and document range of motion (ROM) during clinical evaluation or a physical therapy examination. The technique is used to assess the limitations of a patient's joint and provide information to the clinician that may help determine further treatment.
The study is designed to compare range of motion measurement data for 6 weeks in patients that have been randomized to receive either traditional physical therapy or the MED device. The hypothesis is that patients who use the MED device achieve equivalent range of motion at six weeks as compared to patients participating in traditional standard of care physical therapy.
- Detailed Description
The MED is a commercially available, digital range of motion monitoring device for patients recovering from knee surgery. It displays both flexion and extension measurements and has the option of connecting to an Apple or Android device to send data to the clinician's office for review. Patients will have the capability to log on to the Measuring Every Day website with an assigned username and a password which they create. This will allow them to view their progress and send messages to the study team. Study team members will also have access to this website for review and the ability to send and receive messages. All shared files will reside on an Amazon HIPAA compliant platform.
This is a prospective, randomized, unblinded, single-center study to compare the MED device to traditional physical therapy. The study will include 46 patients who have undergone successful, unilateral total knee arthroplasty. All patients will receive a minimum of 2 physical therapy sessions prior to hospital discharge and also be instructed to flex and extend their operative knee 10 times every 15 minutes while awake as per standard of care after discharge. Patients will be randomized in a 1:1 ratio prior to discharge from the hospital to either: 1) total knee arthroplasty standard of care rehab which consists of 2 weeks of in-home physical therapy consisting of 3 sessions per week starting within 48 hours of hospital discharge, followed by 4 weeks of out-patient therapy three times weekly, or 2) ten repetitions with the MED device three times daily at 8:00am, 2:00pm and 8:00pm. Patients will transmit the 10th measurement of each time point to the clinician's office. Patients randomized to the MED device will be trained on the use of the device prior to hospital discharge.
All enrolled subjects will return to the surgeon's office at Week 2 to have their index knee range of motion measured by the PI or study coordinators with the MED device. If subjects enrolled in the MED device arm do not have a minimum flexion of 90 degrees and extension of -25 degrees, they will be considered screen failures and return to traditional physical therapy.
All enrolled subjects will return to the surgeon's office at Week 6 to have their index knee range of motion measured by the PI or study coordinators using the MED device with the goal of achieving a minimum flexion of 120 degrees and an extension of 0 degrees.
