A PROSPECTIVE STUDY EVALUATING ASSOCIATION BETWEEN TIBIAL PLATEAU FRACTURE MORPHOLOGY WITH LIGAMENT AND MENISCAL INJURY AROUND KNEE.
INTRODUCTION: In the modern world,due to advent of high speed motor vehicles , high energy trauma commonly involves the knee joint and results in complex tibial plateau fractures and associated ligament and meniscal injuries . Proper diagnosis and management of these injuries reduced the chances of degenerative changes around knee joint later on. MATERIAL AND METHOD: A prospective study was conducted in the Department of Orthopaedics in a tertiary health care center of western rajasthan from January 2018 to December 2020 . A total of eighty patients( 62 males: 18 females) with tibial plateau fractures and associated soft tissue injuries were included .Patients were assessed both clinically and radiologically and “ SCHATZKER'S classication was used to classify the tibial plateau fractures. Pre-operatively in every case CT-scan was used to study fracture pattern and MRI was done to see fracture morphology and associated soft tissue injuries. RESULT: A total 80 patient was included in our study,out of which 73 (91.25%) having ligaments( Cruciate and Collaterals) and meniscal injury . Injury to the lateral meniscus was found most frequently in Schatzker II fracture (p<0.0006) and medial meniscus in schatzker IV (p< 0.011). Variable association was shown by ACL and PCL injuries with tibial plateu fracture morphology ,but as the grade of designation increases within schatzker classication as does the frequency of cruciate ligament tear. Overall incidence of LCL rupture occurred least frequently in Schatzker II fractures (7 of 34; 20.5%), which was statistically signicant (P < 0.01). Complete MCL tear occurred in 27( 33.7%) of all fractures and in 41% of Schatzker II fractures. PLC tear had shown signicant association with medial tibial plateu fracture (schatzker IV). CONCLUSION: The likelihood of the cruciate , collateral ligament and PLC injury increases as the grade of designation within schatzker classication (schatzker I-VI). PLC injury had a signicant association with medial tibial plateu fracture (schatzker IV) and MCL had a signicant association with lateral tibial plateau fracture .
