The definitive treatment for knee osteoarthritis is a total knee
replacement, which results in a clinically meaningful improvement in pain and
physical function. However, evidence suggests that physical activity (PA) remains
unchanged after total knee replacement (TKR).
The objective of this
study is to investigate the efficacy, fidelity, and safety of a physical
therapist-administered PA intervention for people after TKR. Design: This study
will be a randomized controlled trial. Setting: The setting is an outpatient
physical therapy clinic. Participants: The participants are 125 individuals who
are over the age of 45 and are seeking outpatient physical therapy following a
unilateral TKR. Intervention: In addition to standardized physical therapy after
TKR, the intervention group will receive, during physical therapy, a weekly PA
intervention that includes a wearable activity tracking device, individualized
step goals, and face-to-face feedback provided by a physical therapist. Control:
The control group will receive standardized physical therapy alone after TKR.
Measurements: The efficacy of the intervention will be measured as minutes per
week spent in moderate to vigorous PA at enrollment, at discharge, and at 6
months and 12 months after discharge from physical therapy. The fidelity and
safety of the intervention will be assessed throughout the study. Limitations:
Participants will not be masked, PA data will be collected after randomization,
and the trial will be conducted at a single site. Conclusions: The goal of this
randomized controlled trial is to increase PA after TKR.
A protocol for
investigating the efficacy, fidelity, and safety of a physical
therapist-administered PA intervention for people after TKR is presented. The
findings will be used to support a large multisite clinical trial to test the effectiveness, implementation, and cost of this intervention.
