Clinical Trial Summary

This study aims to investigate the relationship between pain, gait and activity intensity in HTO patients that are healed and have had their fixation plate removed.

Inclusion criteria are: unilateral HTO with no concurrent procedure performed, fixation plate has since been removed, no subsequent operations performed on the lower limbs (hips to feet). Control participants will be recruited through local advertisements in and around the University of Winchester. Inclusion criteria for the control subjects are: no current pain in the lower limbs, no previous surgery on the lower limbs. Control subjects will also be age-matched to the HTO group.

Knee function and pain scores will first be assessed through the implementation of a Knee Osteoarthritis Outcome Score, a Visual Analogue Scale, and a further pain intensity scale. Once this has been done, resting heart rate (HR) and body mass index (BMI) will also be measured as part of the completion of a Physical Activity Readiness Questionnaire (PAR-Q). A G-Walk gait analysis sensor, which has been validated for use in clinical settings, will then be attached to participants in order to measure spatiotemporal gait parameters during testing.

Each participant will then conduct a series of four walking and four jogging test protocols, each lasting three minutes, on a flat treadmill. The intensity at which the participant must walk or jog during each test will be self-regulated and determined by a rating of perceived exertion (RPE) of 9, 11, 13 or 15 on a 6-20 Borg scale. All participants will be verbally anchored to the Borg scale before conducting the first walk/jog test. The order in which the tests are performed will be randomised in advance of each test session. Half way through each test (90 seconds), participants will be presented with a VAS and pain intensity scale to indicate the current level of pain they are experiencing in their knee. At this stage, they will also be asked to confirm that they are still maintaining the target RPE of that particular test. Once a test is finished, participants will complete another VAS and pain intensity scale and rest in a seated position until their heart rate returns to their pre-determined resting level before the next test commences. The leg for which healthy controls report pain levels will be chosen randomly prior to the test session.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Spatiotemporal parameters of gait	Steps, cadence, speed (etc) measured using G-Walk wireless inertial sensor	9 months recruitment - 2 hours data collection per participant
Primary	Self-reported pain questionnaire	Visual analogues scale (0-10, where 0 = no pain and 10 = the worst imaginable pain)	9 months recruitment - 2 hours data collection per participant
Secondary	Self-reported knee function questionnaire	Knee Osteoarthritis Outcome Score validated questionnaire (score /100, where higher number = better knee function)	9 months recruitment - 2 hours data collection per participant
