This prospective study aims to explore hip arthroscopy, outcome and the effect of the learning curve. Using the non-arthritic hip score preoperatively and postoperatively in 120 patients with an average 23-month follow-up, a median improvement of 16 points was seen at 6 months (p < 0.0001, Wilcoxon's signed ranks) remaining at 2 years (15, p < 0.05). Dividing patients into consecutive chronological groups of 40, the learning curve was explored. At six-months scores improved by 12 (p < 0.05) in first 40, 15 (p < 0.0001) in second and 20 (p < 0.0001) in third. A reduction in THR (22.5%, 5%, 2.5%) and revision rates (10%, 7.5%, 0) was seen. An increase in cumulative percentage satisfaction (defined as minimum 10 points increase) was seen from 20th (45%) to 100th procedure (65%). Results significantly improve as experience increases, possibly due to improved surgical skill, preoperative workup or improved understanding of operative indications.
这项前瞻性研究旨在探索髋关节镜检查、治疗结果及学习曲线的影响。对120例患者在术前和术后使用非关节炎髋关节评分，平均随访23个月，6个月时中位数改善16分（p<0.0001，Wilcoxon符号秩检验），2年时仍保持改善（15分，p<0.05）。将患者按时间顺序连续分为每组40人的组，以探索学习曲线。6个月时，第一组40例患者评分改善12分（p<0.05），第二组改善15分（p<0.0001），第三组改善20分（p<0.0001）。全髋关节置换术（THR）率（分别为22.5%、5%、2.5%）和翻修率（分别为10%、7.5%、0）有所降低。累积满意度百分比（定义为至少提高10分）从第20例手术（45%）到第100例手术（65%）有所增加。随着经验的增加，结果显著改善，这可能是由于手术技巧提高、术前检查改进或对手术适应症的理解增强所致。
