Radiological parameters such as lateral centre edge angle, acetabular index, and T\u00f6nnis grade of arthritis were calculated. Patients also completed a range of patient reported outcome measures. Wilcoxon signed-rank tests were performed to assess for differences between patient\u00a0reported outcome measures and radiological outcomes across the follow-up periods.

At one\u00a0year follow-up all patient\u00a0reported outcome measures were significantly greater than their baseline measurements and this improvement was maintained at two\u00a0years. Changes in patient reported outcome measures were independent of radiological parameters such as change in the lateral centre edge angle and acetabular index, pre-operative T\u00f6nnis grade, and patient factors such as age and sex. A total of 5.11% of patients developed post-operative complications, with four requiring posterior column fixation.
