 starting my paper presentation. So the topic of the paper is MRA evaluation of complex meniscal injuries of knee and analysis of a series of 64 studies was done. I did this paper another guidance with Dr. Poonich and the Lamgari sir, Dr. Amitkarad sir and Dr. Yashrash Patil sir. This study was conducted in Dr. Diya Patil hospital Pooni. So starting with the aims and objective to study the role and to properly characterize the complex meniscal injuries of knee. Next is the materials and methods. So MRA was performed in Simmons Magnetom 1.5 Tesla MRI system and Simmons Magnetom 3D Tesla machine as shown in the figure along with the Neuquil. Next is a protocol that was used. So sequences were taken in proton density facts at codonal exhalant sagittal planes. Sagittal T2 and codonal T1 sequences are taken were taken for each patient as shown in the figure and sample as per the patient's condition and requirements suitable variations for me. So starting on with menisci, they are basically semi-relent fibrocartilages that are triangular in section and they are present in between medial and lateral condyles of TBI and femur. They play a crucial role in stability and kinetics involved in the knee function. So how does an injury occur? As we already know that meniscal injuries are usually seen in a flexed knee that is in 10 to 20 degree flex knee whenever there is twisting injury. So the types of injuries as shown in the figure, they are usually divided into complex and simple tears. So in simple tears we have horizontal, vertical and oblique tears. With complex tears we have pocket handle and complex tears. Associated complexities involved for loose bodies, intra and paraminosclerosis, mastocondal defects and cartilage thinning or loss. I will be showing you some important cases that we included in my study. So this is a case of 30 year old male patient who had a history of twisting knee injury. These are the sagittal and coronal sequences. As we can appreciate that there is injury to the medial meniscus and dividing it into medial and the lateral meniscal fragments. The medial fragment is getting flipped and reaching the intercondyletal notch and in the sagittal plane we can appreciate that it is oriented parallel to the intact posterior cruciate ligament. Given the characteristic double PCL sign that is diagnostic or in some cases important for investigating bucket handle tears. So bucket handle tears are seen, they are basically vertical tears or longitudinal tears with longitudinal extension along the course of meniscus that divide the meniscus into medial and lateral fragments as evident in this case. Next is a case of 21 year old male patient who presented to us with after a history of fall one year back and as we can appreciate it in the sagittal and the coronal PDAFS MRI sequences that there is injury involving the medial meniscus particularly the posterior horn and this is a complex tear that is in two components that is the horizontal and the vertical component. So complex tears usually do not have a specific appearance and can have different components such as in this case. Next is the case of 28 year old male patient who presented to us with a history of pain and swelling in the knee. In these images we can appreciate that there is a complex tear involving the medial meniscus particularly the anterior horn and the body portion with slightly laterally flipped a meniscus fragment. This is considered as an important complication with meniscus injuries. 37 year old male patient next case who presented to us with history of pain and swelling in the knee that pain was progressively increased just prior to the MRI. So here in the MRI we can appreciate that there is involvement of anterior horn the body and the posterior horn of the medial meniscus and there is a horizontal tear. So as you already know that horizontal oblique and in complex tears they usually have poor promises even after surgery. Small tears are usually treated conservatively last day and usually require partial meniscipy and treatment is usually required in young patients as they have a chance of developing arthritis and the weight bearing portion of TBO meniscus TBO femoral joint. Vertical tears as we already know that extend they extend along the course of meniscus so they have excellent chance of healing and they are excellent candidates for surgery in case if it is required. Next are the complexities so this is a case of 22 year old female with the old history of injury while playing. So in axial and these sedative sequences we can appreciate a large cystic lesion that is evident bearing hyper intense on PTFS sequences and this is present at the portion of the anterior horn and a slight at the portion of the little meniscus anterior horn and the anterior portion of the body of the little meniscus and this cystic lesion is showing a few septas so this is a complex system. Next is a case of 48 year old male patient who presented to us with a history of pain and swelling in the knee since six months as it is seen as it is clear as you can clearly see that the meniscus middle meniscus is involved and there is a significant loss of the cartilage along with that few small subcondyle system myrodingyma is evident. So this is a case of contramolaceae and the weight bearing portion of the middle condyles of TBI and femoral. Next is a similar case so this is a 52 year old male patient who had a history of pain and diffuse swelling in the knee since one year. Subcondyle cysts are evident with along with myrodingyma and significant loss of the adjacent cartilage there is slight explosion of the middle meniscus with marked degeneration as well as injury of the middle meniscus and subcondyle cysts and myrodingyma they are seen at the middle condyle of the TBI. Some important so the type of meniscus involved so in majority in out of the 64 studies in major in 21 cases both lateral and middle meniscus was involved isolating middle meniscus even between 38 cases next are the pie charts that depends the portion of the meniscus involved so in cases of middle meniscus the majority in majority cases the posterior horn and the body were involved and similarly in little meniscus posterior and body were more common involved as compared to the anterior horn and the root injuries. Next is the complexities that were what we already saw so in 19 cases osteocondyle loss, osteominal defects along with cartilage sinineal loss was present. Next complexity was a loose body and then the cyst. Next is the type of tear so in middle meniscus injuries the most common tear were the complex tear seen in 36 cases then was the buccaneal tear similarly in the little meniscus the most common were the complex tears and second most common were the horizontal tears. In the next pie charts they depict the same thing. At last a discussion so in this paper we found that meniscus injuries were slightly more common in males and traumatic cases were more common in the degenerative ones. So the maximum number of patients that were found were in the age group of 30 to 40 years of age as we already saw in the previous table so majority of the tears that were found were the complex tears and the second most common were the buccaneal tears, other tears that were considered by the longitudinal oblique in the vertical tears. It has a conclusion so MRI plays a crucial role and it is considered an investigation of choice for diagnosis of menstrual injuries of the knee. A detailed evaluation by MRI can impress some early diagnosis and treatment especially in cases of unstable injuries of me that require early and prompt treatment. MRI can also help in diagnosis of the divisions or injuries that can change the course of treatment particularly in young patients having unstable knee injuries. Thank you.
