The hip, although less commonly affected than the knee, presents a challenging diagnosis and treatment, with magnetic resonance imaging (MRI) as the gold standard for detection. Surgical excision, arthroscopic or open, is the main treatment approach, but there is no consensus on the best strategy for the hip. The aim of this systematic review is to evaluate the clinical outcomes, complications, and revision rates associated with arthroscopic hip surgery for PVNS. Methods: A systematic review was performed following the PRISMA guidelines. Relevant studies were identified by searching four databases: PubMed, Scopus, Embase, and Medline. Selected articles were evaluated according to the criteria of levels of evidence (LoE). For retrospective studies, the Coleman Methodology Score (mCMS) was used. This systematic review was registered with the International Prospective Register of Systematic Reviews. Results: Six studies satisfied the criteria; these involved 77 patients (48% male, 52% female) with a mean age of 26.4 years and a mean follow-up of 54.3 months. MRI and biopsy confirmed the diagnoses, and arthroscopic synovectomy was the primary treatment. Success rates ranged from 80% to 100%, with a recurrence rate of 7.8%, 1.3% requiring revision surgery, and eight (10.4%) patients in three studies reporting conversion to THA. Complications included mild effusions and residual synovitis. All patients who underwent a subsequent total hip arthroplasty were affected by advanced osteoarthritis. Conclusions: Our systematic review reveals that the use of hip arthroscopy in diagnosing and treating PVNS has shown satisfactory results without increasing the risk of recurrence or complications and can return patients to their former activity levels, provided their preoperative osteochondral status is good and there is early management of PVNS of the hip joint.<\/jats:p>","DOI":"10.3390\/jcm13216446","type":"journal-article","created":{"date-parts":[[2024,10,28]],"date-time":"2024-10-28T07:47:18Z","timestamp":1730101638000},"page":"6446","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Arthroscopic Management of Pigmented Villonodular Synovitis of the Hip: A Systematic Review"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1170-230X","authenticated-orcid":false,"given":"Riccardo","family":"Giai Via","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Centro Traumatologico Ortopedico (CTO), University of Turin, Via Gianfranco Zuretti, 29, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matteo","family":"Giachino","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Centro Traumatologico Ortopedico (CTO), University of Turin, Via Gianfranco Zuretti, 29, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9528-6723","authenticated-orcid":false,"given":"Ahmed","family":"Elzeiny","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, Kafr El Sheikh University, Kafr El Sheikh 33516, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9440-7095","authenticated-orcid":false,"given":"Gianvito","family":"Santarsiero","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Centro Traumatologico Ortopedico (CTO), University of Turin, Via Gianfranco Zuretti, 29, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandra","family":"Cipolla","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Centro Traumatologico Ortopedico (CTO), University of Turin, Via Gianfranco Zuretti, 29, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8203-2417","authenticated-orcid":false,"given":"Salvatore","family":"Pant\u00e8","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Centro Traumatologico Ortopedico (CTO), University of Turin, Via Gianfranco Zuretti, 29, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8306-1869","authenticated-orcid":false,"given":"Francesco","family":"Bosco","sequence":"additional","affiliation":[{"name":"Department of Precision Medicine in Medical, Surgical and Critical Care (Me.Pre.C.C.), University of Palermo, 90133 Palermo, Italy"},{"name":"Department of Orthopaedics and Traumatology, G.F.
