Abstract：Objective To investigate the effectiveness and safety of arthroscopic minimally invasive treatment for deep gluteal syndrome(DGS)and establish the classification of DGS under arthroscopy.Methods A retrospective analysis was performed on 32 patients with DGS treated in the Joint Surgery Department of Suining Central Hospital from June 2021 to June 2022.The cohort comprised 15 males and 17 females,ranging in age from 24 to 70 years,with a mean age of(51.62±5.33)years.The number of incisions,surgical duration,and intraoperative blood loss were documented.Pain assessment was conducted using the visual analogue scale(VAS),while hip joint function and patient satisfaction were evaluated using the modified Harris hip score(HHS),modified Benson surgical outcome scores,and DGS scores.These evaluations were performed before surgery,on postoperative day 1,at 2 weeks,3 months,6 months,and 1 year after surgery.Results All patients successfully underwent arthroscopic minimally invasive treatment,with an average surgical duration of(42.36±13.27)minutes and intraoperative blood loss ranging from 5 to 40 mL,averaging(8.16±17.34)mL.No significant neurovascular complications were encountered during or after surgery.Intraoperatively,DGS was primarily classified into four types.Preoperatively,the VAS was(7.52±0.64),and the modified HHS was(56.82±3.23).On the first postoperative day,the VAS decreased to(2.27±0.56),and the modified HHS increased to(84.19±5.76),both showing statistically significant differences compared to preoperative scores(P＜0.05).At 6 months postoperatively,the VAS further decreased to(0.45±0.51),and the modified HHS improved to(95.34±2.73),also demonstrating statistically significant differences from preoperative scores(P＜0.05).During the 1-year follow-up,the DGS quantitative scores gradually declined,and at 1 year postoperatively,all cases had a score of 6 or less.Comparisons between preoperative and postoperative scores revealed statistically significant differences(P＜0.05).The 1-year follow-up revealed excellent patient satisfaction in 27 cases,good in 2 cases,and fair in 3 cases,resulting in an excellent and good satisfaction rate of 90.63％.Conclusion Arthroscopic minimally invasive treatment for DGS,particularly the sciatic nerve deep gluteal space release technique,is proven to be safe with minimal trauma.It effectively and rapidly alleviates pain,resulting in high patient satisfaction rates.
