Changing the care pathway for hip and knee replacement patients
P
eople with late stage hip or knee osteoarthritis may receive a joint replacement to relieve pain and improve mobility. The
operation is considered a success, with regard to patient reported outcomes. However, studies using GaitSmart on hip and
knee replacement patients one year post op show that less than 50% return to a normal gait and that these gait deficiencies can
result in osteoarthritis in other joints, poor mobility and even falls if not corrected. People adapt their gait due to pain in the
arthritic joint. Once the joint pain is gone, the patient needs retraining to walk correctly and weakened muscles strengthened.
The current care pathway provides patients with physiotherapy for up to 6 weeks post op, guiding the patient to move the joint
and become mobile. However, as it takes 10 weeks for the process of muscle strengthening to start, patients are signed off before
gait retraining can really start. Patients are unaware of how they have adapted their gait; for example, excessive medial-lateral
movement of the thigh i.e. swinging the leg around the body rather than under the body. Therefore, the walking pattern remains
the same, loading other joints incorrectly and poor use of their muscles. This paper proposes a new care pathway for patients,
where gait kinematics is measured in the outpatient clinic using inertial sensors. A report describing the gait deficiency and the
severity, using simple traffic light coding, together with a personalized exercise program is provided to the patient at the end of
their 15 minute session. Tests performed at 6, 12, 24 and 52 weeks post op monitor progress and allow the exercises to become
more demanding as the patient improves. Evidence of the clinical efficacy of this approach will be presented.
