Preoperative general data, intraoperative variables such as operation time and blood loss, and postoperative assessments of Harris Hip Score, Visual Analog Scale (VAS), as well as imaging evaluations through X-ray and MRI for femoral head shape restoration and healing, were conducted at 1\u00a0week, 4\u00a0weeks, 3\u00a0months, 6\u00a0months, and 12\u00a0months post-surgery.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A follow-up of more than 2\u00a0years was conducted for both groups of patients.

Group A patients had significantly better Harris Hip Scores at 3, 6, and 12\u00a0months postoperatively, as well as significantly lower VAS scores at 4\u00a0weeks, 3\u00a0months, 6\u00a0months, and 12\u00a0months post-surgery compared to Group B (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.05). In Group A, 3 patients experienced elevated body temperature (maximum 38.6\u00b0C), which was considered to be postoperative absorption heat; their temperatures returned to normal within 2\u20133\u00a0days following symptomatic treatment. All surgical incisions in both groups healed well, with no vascular or nerve injuries or other related complications. Additionally, imaging results showed that 4 hips in Group A developed femoral head collapse, compared to 10 hips in Group B. In Group A, 4 patients (4\/45, 8.9%) with collapse were in ARCO stage II, while in Group B, 6 patients (6\/38, 15.7%) were in ARCO stage I and 4 patients (4\/38, 10.5%) were in ARCO stage II. Overall, Group A had a non-collapse rate of 91.1% (41\/45) in early-stage femoral head necrosis, which was significantly higher than Group B\u2019s 73.7% (28\/38) (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Intraosseous Endoscopic-assisted lesion debridement combined with free fibular grafting shows superior clinical efficacy compared to CD in the treatment of femoral head necrosis.
