Knee joint internal abduction moments of force during running at 4m/s [ Time Frame: First day of joining the study ] [ Designated as safety issue: No ]
Motion analysis trials will be conducted on each subject with both the control and intervention footwear. Inverse dynamics calculations will reveal the internal joint loading for each subject. Knee joint moments will be compared within subjects for each footwear condition.

Change in subjective levels of perceived knee pain over six weeks [ Time Frame: Upon initial recruitment to the study, and once per week for six weeks thereafter ] [ Designated as safety issue: No ]
Pain levels will be recorded by 100mm visual analog scale during weeks 1, 2, 3, 4, 5 and 6 of the study to monitor the efficacy of the intervention. Final change in pain will be compared between groups.

Treatment for Patellofemoral Pain Syndrome Using Footwear
Treatment for Patellofemoral Pain Syndrome Using Knee Abduction Moment-Reducing Footwear

Patellofemoral pain syndrome (PFPS) is the most common running injury and is believed to be associated with higher than normal knee joint loading. Footwear has been developed that may decrease these knee loads in healthy subjects, but their effects on patients with PFPS are unknown. In this study, we aim to test the effects of such footwear on patients with PFPS. We hypothesize that patients who receive the footwear intervention will show a decrease in knee joint loading, and consequently will show improvements in subjective levels of perceived knee pain over a period of six weeks compared to a control condition.

Phase 1
Phase 2
Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
Patellofemoral Pain Syndrome
Device: Knee abduction moment-reducing footwear
Patients in each study group will be asked to run using their assigned footwear at least 3 times per week (minimum 15 km per week) for six weeks. Each patient will document their perceived knee pain each week throughout the six week intervention.
  • Experimental: Knee abduction moment-reducing footwear
    Footwear that is known to decrease knee abduction moments of force in healthy subjects. May include orthotics, or footwear that allows relative movement between the heel section of the outsole and rest of the shoe.
    Intervention: Device: Knee abduction moment-reducing footwear
  • Placebo Comparator: Control footwear
    Standard, off-the-shelf running shoes with no mechanical modifications.
    Intervention: Device: Knee abduction moment-reducing footwear
