Title

Effectiveness of Methylene Blue in the Prevention of Stifle Joint Arthrofibrosis in Rabbit Models

Pages

  269-277

Abstract

 Background: One of the major challenges in orthopedic surgery is the prevention of Fibrosis/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">ArthroFibrosis, which can be successfully alleviated in its early stages. Many studies suggest the administration of Methylene blue (MB) as an accessible and effective agent for the prevention of post-operation adhesions. The purpose of this study was to evaluate the efficacy of MB in the prevention of Fibrosis/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">ArthroFibrosis. Methods: This study was conducted on 18 New Zealand white female mature rabbits. The Anterior cruciate ligament of the left Stifle joint of each animal was cut during aseptic surgery. In the next step, the rabbits were divided into three groups based on their treatments. The rabbits in the first, second, and third groups were subjected to the injection of normal saline, 1% MB solution, and 2% MB solution into their synovial space, respectively. The postoperative stifle range of motion was measured every week. After 4 weeks, the animals were euthanized and all joints were dissected for histopathology. Results: The histopathological evaluation of tissues indicated the presence of fibrotic connective tissue as a sign of Fibrosis in all groups. The Fibrosis rate, inflammatory rate, tissue disarrangement, fibroblastic cellularity, and granulation tissue formation were at their highest levels in the 1% MB group. The integrity of articular cartilage in the 2% MB group was lower than the other groups. The level of bone degeneration was similar in both MB groups; however, it was more than the control saline group. The range of motion was reduced during the first week, then increased in the second and third weeks, and finally decreased in the fourth week. Conclusion: The MB was not an effective method regarding the prevention or treatment of arthoFibrosis and the subsequent osteoarthritis. In contrast with previous studies, Fibrosis was lower in the high dose MB group, compared to the low dose MB group. The alterations in the range of motion were related to the reduced movement caused by the pain and stiffness of the operated joints. The current study can be considered as the first report addressing the adverse effect of MB on synovial components.
