Effectiveness of endoscopic trans-tendineous repair for partial-thickness tears of medius gluteus: A systematic review of literature

Abstract

Tears of the gluteus medius can result in chronic hip pain over time. Pathological onsets involving the gluteus medius cause pain and weakness of abductor strength. Endoscopic repair is a suitable, effective and safe surgical alternative to traditional open techniques and give satisfactory results over time restoring the footprint of gluteus medius. The purpose of this systematic review is to analyse the effectiveness of endoscopic trans-tendinous technique for partial-thickness tears, analysing the subjective and functional outcome over the time. A search of literature (PubMed, Scopus, WebOfKnowledge) was performed. The PRISMA method was used to screen the articles. A total of 4 articles was screened and included for qualitative analysis. For data extraction patient characteristics, pre-clinical examination, imaging, timing from symptoms to surgery, technique performed, subjective scales, functional outcomes, post-operative clinical assessment were analysed. Subjective scores at mean follow-up of 18 months show a significative improvement in all the scales reported, in relief of pain (VAS score) and in terms of strength of abductor. Trans-tendinous technique represents the gold standard to treat endoscopically these injuries. Furthermore, other studies with larger number of patients and longer follow-up are required to validate the best surgical approach for these injuries.
