Abstract:
[Objective]Tibial plateau fracture may be combined with soft tissue injuries including menisci injuries, but what tibial plateau fractures influence on meniscus healing has never been reported. This study is to observe the influence on menisci healing caused by knee variation when tibial fracture occurred by making animal models.[Method]Lateral tibial plateau fracture models and non-full-thickness laceratin and perforation defect of menisci models were made in 12 New Zealand rabbits, along with control group without fractures. The differences of menisci healing between two groups were observed with morphological and light microscopic observation after 12 weeks.[Result]No menisci repair in avascular portion could be found in both groups, menisci laceration within vascular portion had repaired the fissures in both groups, and hardly been distinguished from normal tissue. Perforation defect in one third of lateral side coulc be partially filled with protein clot in tibial plateau fractures group.[Conclusion]No evidence revealed that fracture could prevent menisci healing when tibial plateau fractures combined with menisci injury, however, defects of menisci may get advantage of filling tissue from fracture. It still need further research whether it is good for menisci healing or not.
