The patient presented to us after 3 months of the injury with an inability to extend the knee. We undertook a surgical repair of the muscle tear using the modified Mason-Allen technique and a polypropylene mesh augmentation. To the best of our knowledge, the use of polypropylene mesh for repair augmentation of mid-substance tear of quadriceps muscle has never been described in the literature. The patient had achieved a full active knee extension at 9 months following the surgery. At 3 years of follow-up, the patient has maintained the movements and strength of the knee. He has no functional limitations and is satisfied with the outcome. Thus, the middle term results are good and the treatment is promising.<\/jats:p>","DOI":"10.1136\/bcr-2020-239863","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T11:32:26Z","timestamp":1614771146000},"page":"e239863","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Result of delayed repair of quadriceps muscle following a sharp cut injury"],"prefix":"10.1136","volume":"14","author":[{"given":"Hira Lal","family":"Nag","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3458-189X","authenticated-orcid":false,"given":"Gunjar","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mayur","family":"Nayak","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8193-7625","authenticated-orcid":false,"given":"Archit","family":"Goyal","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,3,3]]},"reference":[{"key":"2025082801412912000_14.3.e239863.1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2014-094285"},{"key":"2025082801412912000_14.3.e239863.2","first-page":"14","article-title":"Muscle injuries: a brief guide to classification and management","volume":"12","author":"Maffulli","year":"2015","journal-title":"Transl Med UniSa"},{"key":"2025082801412912000_14.3.e239863.3","doi-asserted-by":"publisher","DOI":"10.5402\/2012\/689012"},{"key":"2025082801412912000_14.3.e239863.4","doi-asserted-by":"crossref","first-page":"300","DOI":"10.32098\/mltj.02.2020.15","article-title":"Surgical treatment of muscle injury.
