Primary Outcome Measures

Name	Time	Method
Knee Adduction Moment	Change from baseline to immediately after 8 weeks of retraining	Knee Joint Loading (%Bw\*Ht) will be assessed at baseline and immediately after gait retraining

Secondary Outcome Measures

Name	Time	Method
Medial knee compartment qMRI	Change from baseline to 6 months after retraining	Changes to quantitative MRI measures at 6 months after retraining will be correlated with changes to joint loading
Serum inflammatory markers	Change from baseline to immediately after 8 weeks of retraining	Changes to serum inflammatory markers immediately after the end of training from baseline will be correlated with changes to joint loading
Knee Adduction Moment	Change from baseline to 6 months after retraining	Knee Joint Loading (%Bw\*Ht)
