Purpose: To determine if previous local steroid injection can alter the patient response to endoscopic plantar fascia release.

Methods: It is a prospective non-randomized comparative study of 100 adult patients, suffered from plantar fasciopathy for at least one year, and had reported either temporary or no response to two or more of conservative treatments, including local corticosteroid injection. Enrolled patients were non-randomly allocated by convenience sampling into two groups. The first 50 patients who reported improvement in response to local corticosteroid injection were allocated to Group (A) The first 50 patients who did not report any improvement after injection were allocated to group (B) Both groups underwent endoscopic plantar fascia release. Clinical evaluation was carried out using the visual analogue scale (VAS), American Orthopaedic Foot and Ankle-Hindfoot Scale (AOFAS) and Patient self-assessment (Roles and Maudsley score) preoperatively and at 4, 8 weeks, 3, 6, 12, and 24 months postoperatively.

Results: Both groups showed a statistically significant improvement in VAS for heel pain, AOFAS score, and Roles and Maudsley score. Group A demonstrated significantly better VAS, AOFAS, and self-assessment scores than group B at different follow-up intervals. Furthermore, trajectory analysis showed faster pain relief and functional recovery was observed in group A compared to group B.

Conclusion: Patients who experienced temporary improvement after local corticosteroid injection had better clinical outcomes following endoscopic plantar fascia release.

Clinical trial number: Not applicable.

目的：

确定之前的局部皮质类固醇注射是否会影响患者对内镜下足底筋膜松解术的反应。

方法：

这是一项前瞻性非随机对照研究，涉及100名成年患者，这些患者至少患有足底筋膜炎一年，并且在接受包括局部皮质类固醇注射在内的两种或更多种保守治疗后报告仅有暂时改善或无改善。通过方便抽样法将入组的患者分配到两个不同的组中。前50位在局部皮质类固醇注射后报告有改善的患者被分配到A组；另外，第一个没有因为注射而有任何改善的50名患者则被分配至B组。两组均接受了内镜下足底筋膜松解术。临床评估在手术前后4周、8周、3个月、6个月、12个月和24个月分别使用视觉模拟评分（VAS）、美国骨科足踝协会-后跟评分量表（AOFAS）以及患者自我评价量表进行。

结果：

两组在VAS、AOFAS评分及Roles和Maudsley评分方面均显示出统计学上的显著改善。与B组相比，A组在不同随访间隔的VAS、AOFAS评分及自我评估得分均表现出更好的效果。此外，轨迹分析显示A组疼痛缓解和功能恢复的速度快于B组。

结论：

在接受局部皮质类固醇注射后曾有暂时改善的患者，在接受内镜下足底筋膜松解术后临床结果更佳。

临床试验编号：不适用。
