Effectiveness of Reduced Frequency Physical Therapy in Total Knee Arthroplasty

Overview

Rehabilitation after Total Knee Arthroplasty surgery involves physical therapy services to address limitations in range of motion, strength, and participation in normal daily activities. This investigation will compare the outcomes from standard physical therapy intervention in comparison to reduced frequency physical therapy sessions supplemented with in-home exercise equipment.

Total knee arthroplasty (TKA) is a common surgical procedure for individuals experiencing pain and reduced physical abilities related to knee pain, most commonly osteoarthritis. Common physical impairments associated with post-operative TKA rehabilitation include: reduced knee range of motion (ROM), reduced strength, reduced participation in activities of daily living, and pain. TKA surgery is routinely paired with physical therapy (PT) interventions post-operatively in order to facilitate recovery for patients electing to undergo this intervention. The Total Range Exerciser (T-REX) is a medical device aimed at reducing the need for post-operative physical therapy services while promoting outcomes. A successful outcome after total knee arthroplasty requires symptom relief and restoration of physical function. Measurement of pain and function can be achieved through patient-reported outcomes measures and objective functional testing. The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a patient-reported outcomes measure intended to capture the individual patient's perception of progress throughout the rehabilitative process. Objective measurements of physical function are necessary to quantify the magnitude of physical impairment associated with the patient's perceived status. Physical function can be measured through standardized assessment of knee ROM, strength, and ambulation. The purpose of this study is to evaluate the effectiveness of standard physical therapy compared to reduced frequency physical therapy supplemented with the (T-REX) after in total knee arthroplasty in subjective and objective measurements of physical function.
