Abstract
Purpose: The study aims to evaluate the outcomes of endoscopic sciatic neurolysis and piriformis release as treatment for piriformis syndrome (PS) with a minimum 2-year follow-up. The secondary aim is to present a comprehensive approach to enhance diagnostic accuracy.
Methods: Prospectively collected data was retrospectively analyzed for all patients who underwent endoscopic piriformis release and sciatic neurolysis as treatment for PS between 2010-2021. A diagnostic algorithm was employed for surgical indications throughout this time period. Included patients had completed pre-operative and minimum of 2-year postoperative questionnaires for the following patient reported outcome (PRO) measures: modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and Visual Analogue Scale (VAS) for pain and patient satisfaction. The minimal clinical important difference (MCID) was calculated for the mentioned PROs and included in the analysis.
Results: A total of 18 patients with a mean follow-up time of 93.1 ± 38.2 months were included in the study. All patients experienced symptom relief postoperatively. Significant improvement was seen at latest follow-up compared to preoperative baseline for mHHS (p < 0.001), NAHS (p < 0.001), HOS-SSS (p = 0.019), and VAS (p < 0.001),as well as a high mean patient satisfaction of 8.3 ± 1.7. Furthermore, a high percentage of patients reached the calculated MCID for mHHS (83.3%), NAHS (77.8%), HOS-SSS (61.1%), and VAS (94.4%).
Conclusion: Endoscopic release of the piriformis tendon and sciatic neurolysis have shown favorable outcomes, high patient satisfaction rates, and a high percentage of patients reaching clinically important thresholds, with a low rate of complications at a minimum 2-year follow-up.
Level of evidence: Retrospective Case Series.; Level IV.
期刊介绍：
Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
