These injuries, particularly common in the fourth and fifth decades of life, significantly affect an individual\u2019s quality of life and athletic performance and require effective treatment strategies. Surgical intervention is indicated when conservative treatments fail, with the primary goal of restoring the mechanical function of the hamstrings. Traditional primary repair may not be feasible in chronic cases with tendon retraction and muscle atrophy. Surgical reconstruction techniques aim to restore tendon integrity and improve symptoms. This technical note describes a surgical technique using gracilis and semitendinosus autografts from the contralateral leg to repair chronic proximal hamstring tears. This approach aims to reinforce the reconstruction and overcome the limitations of direct repair in chronic cases, with the aim of improving strength and durability, offering a promising alternative for patients with significant tendon retraction. Reconstruction of chronic proximal hamstring tears with autografts represents an innovative approach to a challenging clinical problem. This technique offers potential benefits in strength and function restoration, with careful patient selection and surgical technique being crucial for successful outcomes. As evidence for this approach evolves, it may become a valuable tool in managing chronic proximal hamstring tears.<\/jats:p>","DOI":"10.1093\/jhps\/hnaf060","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T11:33:30Z","timestamp":1759145610000},"page":"295-298","source":"Crossref","is-referenced-by-count":0,"title":["Reconstruction of chronic proximal hamstring tear with hamstring autograft\u2014hamstring on hamstring technique: technical note"],"prefix":"10.1093","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1834-6857","authenticated-orcid":false,"given":"Raquel Lima","family":"Cunha","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Unidade Local de Sa\u00fade de Entre o Douro e Vouga , Rua Dr. C\u00e2ndido de Pinho, 4520-211 Santa Maria da Feira, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre","family":"Castro","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Unidade Local de Sa\u00fade de Entre o Douro e Vouga , Rua Dr. C\u00e2ndido de Pinho, 4520-211 Santa Maria da Feira, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuel","family":"Padin","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Hospital da Luz Arr\u00e1bida , PCT de Henrique Moreira 150, 4400-346 Vila Nova de Gaia, Porto ,","place":["Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco","family":"Alpoim","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Hospital da Luz Arr\u00e1bida , PCT de Henrique Moreira 150, 4400-346 Vila Nova de Gaia, Porto ,","place":["Portugal"]},{"name":"Fidelidade Insurance Company \u2013 Clinical Department of Work Related Accidents Assistance , R.
