en The Clinical Efficacy of Fat Injection on the Repair of Hand Flexor Tendon: A Randomized Clinical Trial تخصصي Special مقالات اصيل Original Article Background: In recent years, special attention has been paid to minimally invasive and conservative methods in addition to conventional surgical methods to repair tendon damage. In this regard, the effect of fat injection and graft has been of great interest due to its potential in accelerating tissue repair. We aimed to assess the clinical efficacy of fat injection along with conventional approach in patients with flexor tendon injury. Methods: In this randomized clinical trial, 64 patients were randomly scheduled for tendon repair using the usual modified Kessler four-strand method alone or tendon repair using four-strand method and fat injection on the proximal and distal sides of the repair site in the Hazrat Fatemeh Hospital, Tehran Province, Iran in 2022 (IRCT20221206056723N1). Patients were followed-up for eight weeks regarding the function status of the repaired tendon (using Strickland grading test), range of motion (by physical examination) and flexion and extension gaps (by imaging). Results: In the eighth weeks after the treatment, the average Strickland score was significantly higher in the group receiving fat injection (P: 0.009 ). In the two pointed times, the mean range of motion was significantly higher and the mean flexion and extension gaps were significantly lower in those who received fat injection. None of the procedural side effects were observed in the fifth and eighth weeks after the treatment. Conclusion: Fat injection along with usual surgical treatment for tendon repair accelerates and improves tendon function and range of motion.   Fat injection, Flexor tendon, Repair 41 46 http://wjps.ir/browse.php?a_code=A-10-827-2&slc_lang=en&sid=1 Siamak Farokh Forghani 100319475328460014564 100319475328460014564 No Department of Plastic and Reconstructive surgery, Hazrat Fatemeh Hospital, School of Medicine, Iran University of Medical Sciences, Tehran, Iran.
