Digital navigation shows minor improvement in operative time and leg length outcomes during AA-THA, suggesting benefits during the learning curve.
The use of navigation software in AA-THA is safe and effective to achieve more accurate postoperative leg length. Despite the increase in fluoroscopic time, there was a small but statistically significant reduction in operative time. The value of such technology would be expected to substantially increase if used during the learning curve when introducing AA-THA to contemporary practice.
