Hip and groin function was assessed from preoperatively to 5 years postoperatively with the Copenhagen Hip and Groin Outcome Score (HAGOS) Activities of Daily Living (ADL) and Sports and Recreation (Sport) subscales. Morphology was defined using the anterior alpha angle (AA) and lateral center-edge angle (LCEA) as follows: mild to moderate cam (55\u00b0\u2264 AA &lt; 78\u00b0), severe cam (AA \u2265 78\u00b0), pincer (LCEA &gt; 39\u00b0), and borderline dysplasia (20\u00b0\u2264 LCEA &lt; 25\u00b0). Joint space width (JSW) was defined as slightly reduced (3.1 mm \u2264 JSW \u2264 4 mm) or severely reduced (2.1 mm \u2264 JSW \u2264 3 mm). Acetabular cartilage status was defined by modified Beck grades 0 to 4 and femoral head cartilage status by International Cartilage Regeneration &amp; Joint Preservation Society grades 0 to 4. Acetabular and femoral cartilage injury areas were categorized as &lt;1, 1 to 2, or &gt;2 cm\n                      <jats:sup>2<\/jats:sup>\n                      .
