♦ ACL tear: abnormal fibres, tibial translation, PCL/patella tendon buckling, bone bruising♦ Meniscal tear: signal change to free edge♦ Bone bruising:• Reticular—not continuous subarticular bone• Geographic—extends to subarticular bone♦ Posterolateral corner:• Oblique slices through fibular head• Consists of lateral collateral ligament, popliteus, popliteofibular ligament, and arcuate complex.Magnetic resonance imaging (MRI) has revolutionized the investigation and treatment of the painful knee. It is non-invasive and avoids patient exposure to ionizing radiation. MRI has the advantage of establishing diagnoses in a painful knee without the morbidity of surgical intervention. It is now widely available and has moved from a simple diagnostic adjunct into a key planning tool. It offers improved management of theatre resources and it allows for more accurate planning of postoperative rehabilitation.The role of MRI in management of the injured knee is determined by its cost-effectiveness and its ability to augment the diagnostic accuracy of clinical examination. Accuracy of clinical examination by specialist orthopaedic surgeons is comparable to MRI when interpreted by specialist radiologists (Table 8.3.1). Increasingly, MRI has been shown to be cost neutral. Whilst costs are high, diagnostic information reduces the need for unnecessary surgery.

The popliteal hiatus is a complex region, formed by the confluence of various structures connecting the meniscus, popliteal tendon, tibia and fibula. The main structures that can be found are the three popliteomeniscal fascicles (anterior, postero-inferior and postero-superior), the lateral and posterior meniscotibial ligaments, the popliteofibular ligament and the meniscofibular fascicle. These structures can be identified in most cases using magnetic resonance imaging, and their ‘static’ assessment can be performed. Arthroscopic assessment is useful in identifying and testing ‘dynamically’ the integrity of the structures around the popliteal hiatus. Injuries or abnormalities of the popliteal hiatus and its structures could result in meniscal hypermobility and subluxation; however, these injuries are often unrecognized. Possible abnormalities in this region, apart from the well-known bucket-handle meniscal tear, are the Wrisberg Type III discoid meniscus, and meniscal fascicles tears.

Painful Knee

Background: Painful knee is considered as one of the most common causes of morbidity and disability affecting all age group. It happens due to varied reasons ranged from injury to various disease processes. The present study documented the magnetic resonance imaging (MRI) findings in painful knee.Methods: A hospital based cross-sectional study was conducted among 100 painful knee patients referred to the Radiodiagnosis department of the Midnapore Medical College of West Bengal for evaluation. MRI scans performed using GE 1.5 Tesla  MRI scanner. Results were expressed in terms of numbers and proportions.Results: The commonest soft tissue lesion found was meniscal tears which mainly involved posterior horn of the medial meniscus and of grade 2 nature. In case of any injury, vertical meniscal tear was found the commonest type. Tear was found the commonest lesion involved the anterior-cruciate ligament (ACL), mostly acute in nature while partial tear commonly found in posterior-cruciate ligament (PCL). Nearly one-third (30%) had features of bone contusions; mostly tibia followed by lateral femoral condyle. Popliteal cyst was the commonest cystic lesion and was associated with effusions and meniscal tears while patello-femoral compartment mostly involved by the osteo-arthritic process.Conclusions: MRI is an ideal, non-invasive and more precised imaging technique for the radiological evaluate of the painful knee condition for better clinical management.

Calcaneal Apophysitis

Calcaneal apophysitis (Sever’s disease), is the most frequent cause of the heel pain in growing children. The diagnosisis generally made with a typical history and clinical examination. Imaging modalities including radiography and magnetic resonance imaging can help establish the diagnosis. In this case we report imaging findings of an 11-year-old boy diagnosed as Sever’s disease.J Nepal Paediatr Soc 2015;35(2):172-174

Percutaneous Sclerotherapy

Objectives To examine three different methods for evaluating the effect of percutaneous sclerotherapy on limb venous malformations in a series of patients with a relatively long follow-up. Method The study was a retrospective study. Results Thirty-eight patients treated with percutaneous sclerotherapy underwent sclerotherapy, with a median number of sessions of 4 (range, 1–10). They were followed up for 1–60 months (average 12.5 months). The kappa between clinical manifestations and Doppler ultrasound was 0.684 ( P < 0.001). The kappa between clinical manifestations and magnetic resonance imaging was 0.217 ( P = 0.006). The kappa between Doppler ultrasound and magnetic resonance imaging was 0.323 ( P < 0.001). The rate of grade IV patients evaluated by clinical manifestations was significantly higher than that by Doppler ultrasound and magnetic resonance imaging. Conclusions Magnetic resonance imaging is the gold standard for VM imaging. Its consistency with clinical examination and Doppler ultrasound is poor, and Doppler ultrasound and clinical examination could be more appropriate for follow-up imaging after sclerotherapy.
