The exclusion criteria were as follows: LCEA &lt;18\u00ba or &gt;25\u00ba, previous ipsilateral hip surgery or conditions, and T\u00f6nnis grade &gt;1. The modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), and visual analog scale (VAS) for pain and patient satisfaction were reported. Clinical benefit was assessed via minimal clinically important difference (MCID), the patient acceptable symptomatic state (PASS), and the maximum outcome improvement (MOI). Survivorship was defined as nonconversion to total hip arthroplasty. A sex-based propensity-matched comparison was made in a 1-to-1 ratio based on age, body mass index (BMI), and T\u00f6nnis grade.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Propensity-score matching created a cohort of 152 hips, 76 per group.
