The bio-absorbable suture anchor is a novel internal fixation for PCLAF. This study aims to estimate and compare the safety, efficacy, and functional outcomes between the bio-absorbable anchor and the traditional suture pull-out technique for arthroscopic fixation of PCLAF.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> This was a prospective cohort study. PCLAF patients were included from 1 January 2020, to 31 August 2021, in our department, and randomly divided into the absorbable anchor group and control group (pull-out suture fixation). Clinical assessments included: post drawer test, gravity test, anterior-posterior laxity (KT-2000), range of motion, Lysholm and International Knee Documentation Committee (IKDC) scores, total failure rate, and returning to sports rate. The minimum follow-up was 1\u00a0year (y).<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> 31 patients had accomplished the 1\u00a0year follow-up (missing rate: 13.9%). We did not face any complications such as neurovascular injury, fever, infection, un-union, or re-rupture during the follow-up. CT scan showed that all of the patients in the two groups had a well bone union at 3\u00a0months in post-operation. At 1\u00a0year follow-up, the total failure rate of the bio-absorbable anchor group (1\/17, <jats:italic>p<\/jats:italic> = 0.036) was lower than the control group (5\/14), and the IKDC (86.24 \u00b1 4.35, <jats:italic>p<\/jats:italic> = 0.008) and return to sports rate (11\/17, <jats:italic>p<\/jats:italic> = 0.045) of the bio-absorbable anchor group were higher than that of the control group (81.43 \u00b1 5.06) (4\/14).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Both the bio-absorbable anchor and suture pull-out technique for arthroscopic fixation of PCLAF have acquired a well bone union and superior safety, but the bio-absorbable anchor group had better efficacy and functional outcomes than the traditional pull-out technique.<\/jats:p>","DOI":"10.3389\/fbioe.2022.1055176","type":"journal-article","created":{"date-parts":[[2022,11,16]],"date-time":"2022-11-16T04:19:53Z","timestamp":1668572393000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["The safety, efficacy, and functional outcomes on arthroscopic fixation of posterior cruciate ligament avulsion fracture by a bio-absorbable anchor or traditional pull-out technique: A prospective cohort study"],"prefix":"10.3389","volume":"10","author":[{"given":"Xiangyu","family":"Ren","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shulong","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhe","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianda","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teng","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoxin","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhong","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,11,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1065","DOI":"10.1016\/j.arthro.2015.10.013","article-title":"Biomechanical properties of different fixation techniques for posterior cruciate ligament avulsion fractures","volume":"32","author":"Domnick","year":"2016","journal-title":"Arthrosc.
