The Effect of Different Saline Suspension Height on Injured Articular Cartilage During Arthroscopic Surgery.
ObjectiveSaline is typically suspended at a certain height to maintain a clear surgical field in arthroscopic surgery. The effects of saline on cartilage have been extensively studied; however, the impact of the pressure generated by saline solution suspended at different heights on injured cartilage is largely unknown. This study investigates suspension-height-dependent cellular responses and tissue damage in traumatized cartilage.MethodsOsteochondral explants were harvested from porcine stifle joints, then were cut perpendicularly before immersed or irrigated for 2 hours with saline at 4 heights (80/105/130/155 cm). The explants were then transferred to and cultured in chondrogenic medium for 5 days. Chondrocytes viability was subsequently assessed with confocal imaging. Cell response was assessed with expression levels of proapoptosis and proinflammatory genes. Tissue damage was evaluated by secretome analysis of proinflammatory cytokines and extracellular matrix and histological test.ResultsIrrigation exacerbated cut-induced chondrocytes death in superficial zone of cartilage, with mild change on 80 cm, 105 cm, 130 cm and severe damage on 155 cm. Similarly, explants that underwent irrigation with heights of 80 cm to 130 cm exhibited relatively slighter change of gene expression of BAX, BCL2, IL-6 and NOS2 and release of GAG, IL-6 and NO to a comparable extent.ConclusionThis study provides evidence of damaging effects of irrigation on injured cartilage surface. Suspension heights of 80 cm to 130 cm led to comparable minor cartilage damage.
期刊介绍:
CARTILAGE publishes articles related to the musculoskeletal system with particular attention to cartilage repair, development, function, degeneration, transplantation, and rehabilitation. The journal is a forum for the exchange of ideas for the many types of researchers and clinicians involved in cartilage biology and repair. A primary objective of CARTILAGE is to foster the cross-fertilization of the findings between clinical and basic sciences throughout the various disciplines involved in cartilage repair.
The journal publishes full length original manuscripts on all types of cartilage including articular, nasal, auricular, tracheal/bronchial, and intervertebral disc fibrocartilage. Manuscripts on clinical and laboratory research are welcome. Review articles, editorials, and letters are also encouraged. The ICRS envisages CARTILAGE as a forum for the exchange of knowledge among clinicians, scientists, patients, and researchers.
The International Cartilage Repair Society (ICRS) is dedicated to promotion, encouragement, and distribution of fundamental and applied research of cartilage in order to permit a better knowledge of function and dysfunction of articular cartilage and its repair.
