PRIMARY outcome

Timeframe: Day 0

Population: Participants were recruited for the trial but due to poor recruitment and logistical challenges none of the participants underwent any of the proposed assessments and as such no outcome data was collected. The trial terminated due to poor recruitment.

SECONDARY outcome

Timeframe: Day 0

Population: Participants were recruited for the trial but due to poor recruitment and logistical challenges none of the participants underwent any of the proposed assessments and as such no outcome data was collected. The trial terminated due to poor recruitment.

The gold standard will be grade of arthritis at time of surgery in those patients undergoing knee replacement as part of their routine clinical care. Each compartment will be graded independently. An X-ray demonstrating a joint space width (JSW) of 0mm will be classified as full thickness cartilage loss, a JSW of \>0mm but \<4mm will be classified as partial thickness cartilage loss and a JSW of 4mm or greater will be classified as preserved full thickness cartilage. The sensitivity of each view at predicting the observed grade of cartilage disease within each compartment at the time of surgery will be recorded.
