The injury included a complete patellar tendon rupture from the apex of the patella, a 1\u2009mm deep transverse cut in the femoral condyle and a partial rupture of the anterior cruciate ligament. The tendon rupture was repaired with transosseous suture repair without augmentation. A knee brace was used for 8\u2009weeks, with a gradual decrease in flexion restraints. A rehabilitation programme was overseen by a dedicated physiotherapist. At 6 months, he started a gradual return to skating sessions. After 1\u2009year, he had symmetrical single-legged hop performance, but quadriceps weakness due to pain. The patient returned to competition speed skating at national levels after 11 months, and within the first postoperative year, he was breaking new personal records on the ice.<\/jats:p>","DOI":"10.1136\/bcr-2018-228611","type":"journal-article","created":{"date-parts":[[2019,4,15]],"date-time":"2019-04-15T07:49:15Z","timestamp":1555314555000},"page":"e228611","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Knee sliced open by skate blade: complete patellar tendon rupture in an elite long track speed skater"],"prefix":"10.1136","volume":"12","author":[{"given":"Alexander Nagel","family":"Tandberg","sequence":"first","affiliation":[{"name":"Orthopaedic Department, Baerum Hospital, Vestre Viken Hospital Trust, Akershus, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hege","family":"Grindem","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Oslo Sport Trauma Research Center, Norwegian School of Sport Sciences, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Wiig","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, Vest helse og trening AS, Akershus, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wender","family":"Figved","sequence":"additional","affiliation":[{"name":"Orthopaedic Department, Baerum Hospital, Vestre Viken Hospital Trust, Akershus, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,4,14]]},"reference":[{"key":"2025082703312995000_12.4.e228611.1","first-page":"S67","article-title":"Acute and old ruptures of the extensor apparatus of the knee in adults (excluding knee replacement)","volume":"99","author":"Saragaglia","year":"2013","journal-title":"Orthopaedics & Traumatology: Surgery & Research"},{"key":"2025082703312995000_12.4.e228611.2","unstructured":"Marder RA , Timmerman LA .
