Despite its advantages, there is currently no standardized protocol for arthroscopic hip synovectomy, and complete removal of intra\u2010articular loose bodies remains challenging. The objective of this study is to evaluate long\u2010term clinical outcomes of arthroscopic treatment for hip synovial chondromatosis using a standardized protocol based on clock\u2010face\u2010guided, imaging\u2010based lesion localization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A consecutive cohort of patients undergoing arthroscopic treatment and diagnosed with synovial chondromatosis between June 2016 and July 2019 was included in the study. All patients underwent preoperative imaging\u2010guided localization of loose bodies followed by arthroscopic removal performed by a single surgeon, with a minimum postoperative follow\u2010up of 30\u2009months. Preoperative and postoperative assessments included standard radiographs (x\u2010ray), three\u2010dimensional computed tomography (3D\u2010CT), magnetic resonance imaging (MRI), intraoperative arthroscopic images, visual analog scale (VAS) for pain, range of motion (ROM), modified Harris Hip Score (mHHS), and International Hip Outcome Tool (iHOT\u201012). The percentage of patients achieving the minimal clinically important difference (MCID) was calculated to summarize and compare differences in clinical outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Seventeen patients were enrolled, with a mean postoperative follow\u2010up duration of 71\u2009months.

PROs demonstrated significant improvements: VAS for pain decreased from 7.6 to 2.1, mHHS increased from 54.6 preoperatively to 89.4 postoperatively, and iHOT\u201012 improved from 38.1 to 75.2 (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
