Data were collected on patients who underwent hip arthroscopy. The inclusion criteria were acetabular microfracture; concomitant treatment for labral tears and FAI syndrome; and preoperative modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score\u2013Sports Specific Subscale, and visual analog scale. Exclusion criteria were Workers' Compensation, preoperative T\u00f6nnis grade &gt;1, or previous ipsilateral hip surgeries or conditions. Patients were grouped based on smaller chondral defects (SCDs) or larger chondral defects (LCDs), then matched 1:1 by age at surgery \u00b110\u00a0years, sex, body mass index \u00b15, labral treatment, capsular treatment, acetabuloplasty, and femoroplasty.

Before matching, the conversion rate to THA was higher for LCDs (24.6%) than for SCDs (12.0%). Thirty\u2010five patients were matched for each group. Mean follow\u2010up time was 47.9\u00a0months (range, 24.0, 84.1) for the matched LCD group and 46.1\u00a0months (range, 24.0, 88.1) for the matched SCD group.
