Abstract (original English)

Anterior cruciate ligament (ACL) injuries are among the most common sports-related injuries, often requiring surgical reconstruction to restore joint stability and function. However, inflammation and graft-to-bone healing remain critical challenges in postoperative recovery. Micro-fragmented adipose tissue (MFAT), rich in mesenchymal stem cells and anti-inflammatory factors, has shown potential in promoting tissue repair and reducing inflammation. This randomised controlled trial aims to evaluate the efficacy of MFAT injection in enhancing graft-to-bone healing at both the tibial and femoral sides and alleviating postoperative inflammation in ACL reconstruction. This is a prospective randomised controlled trial involving 70 patients with acute ACL injuries. Participants will be randomised into two groups: a standard ACL reconstruction group and an ACL reconstruction plus MFAT injection group. In the latter group, MFAT will be prepared from the infrapatellar fat pad and injected intra-articularly during surgery. All patients will follow a standardised postoperative rehabilitation protocol. Data will be collected at baseline and 3, 6 and 12 months postoperatively. Primary outcomes include graft maturity, assessed by signal-to-noise quotient on MRI at 6 and 12 months. Secondary outcomes include visual analogue scale scores, International Knee Documentation Committee scores and inf
