These injuries, because of their inherent nature and associated complications, may require a complex treatment and remains a challenge for orthopaedic surgeons. Current surgical techniques present significant complications, including patellar fracture, damage to patellar articular cartilage, and abnormal patella height. This note describes a surgical technique to provide an additional reinforcement to the patellar tendon repair with a semitendinous autograft, without the necessity to perform any transosseous tunnels at the patella bone. First, the patellar tendon is repaired with an end\u2010to\u2010end technique and the semitendinous tendon is harvested. A transosseous tunnel at the tibial tubercle is drilled and 2 rents are made, both medial and lateral to the retinaculum at the level of the intermedial segment of the patella close to the patellar margin. The graft is passed through the tunnel and rents in a U\u2010shaped form. The graft is sutured along the length of the patellar tendon on both margins in tension at 30\u00b0 of knee flexion. Fluoroscopy imaging is performed to assess the patella height. This technique provides a significant augmentation of patellar tendon, avoiding the potential patella bone tunnel complications.<\/jats:p>\n <\/jats:sec>\n \n Technique Video<\/jats:title>\n \n \n \n video<\/jats:alt-text>\n <\/jats:graphic>\n <\/jats:boxed-text>\n <\/jats:p>\n \n See video under supplementary data.<\/jats:bold>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1016\/j.eats.2017.08.035","type":"journal-article","created":{"date-parts":[[2017,11,27]],"date-time":"2017-11-27T07:32:18Z","timestamp":1511767938000},"update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":15,"title":["Augmentation of Patellar Tendon Repair With Autologous Semitendinosus Graft\u2014Porto Technique"],"prefix":"10.1002","volume":"6","author":[{"given":"Jo\u00e3o","family":"Espregueira\u2010Mendes","sequence":"first","affiliation":[{"name":"Orthopaedics Department of Minho University Minho Portugal"},{"name":"Cl\u00ednica do Drag\u00e3o Espregueira\u2010Mendes Sports Centre\u2013FIFA Medical Centre of Excellence Porto Portugal"},{"name":"Dom Henrique Research Centre Porto Portugal"},{"name":"3B's Research Group\u2013Biomaterials Biodegradables and Biomimetics University of Minho Headquarters of the European Institute of Excellence on Tissue Engineering and Regenerative Medicine Barco, Guimar\u00e3es Portugal"},{"name":"ICVS\/3B's\u2013PT Government Associate Laboratory Braga\/Guimar\u00e3es Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renato","family":"Andrade","sequence":"additional","affiliation":[{"name":"Cl\u00ednica do Drag\u00e3o Espregueira\u2010Mendes Sports Centre\u2013FIFA Medical Centre of Excellence Porto Portugal"},{"name":"Dom Henrique Research Centre Porto Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.J.S.
