“…In addition, twenty seven patients with normal X-ray findings had added osseous findings, soft tissue findings or both osseous and soft tissue findings only detectable by MRI. This agreed with a study by Fahmy et al (10) , who found an additional value of MRI in detection of bony, cartilage and soft tissue findings in AKP and findings by Diederichs et al (12) , who reported that up to 60% of osteochondral lesions of the knee may go unnoticed on X-rays. Furthermore, we found that ten patients with X-ray findings of osteoarthritis had additional osseous findings or both osseous and soft tissue findings only detectable by MRI.…”

“…This could be explained by higher physical activity and higher incidence of sports injury in males. Fahmy et al (10) reported a similar male predominance, but Diederichs et al (12) stated a majority of female patients in their study. This study was based on a previous study by Fithian et al (14) , in which a larger sample size, lower mean of age of patients, and different study design was used.…”

“…MRI has more recently been used in the evaluation of either acute or chronic causes of AKP, as it can detect the pathology causing pain either in the bones, cartilage or soft tissues (10) . MRI can also be used for calculation of TT-TG distance and other measurements such as trochlear angle, trochlear depth and patellar height, which are important in diagnosis of patellofemoral instability and can detect any associated soft tissue or articular cartilage abnormalities without the need for further evaluation with CT scan.…”

Background: Anterior knee pain (AKP) is the commonest cause of knee complaints. It represented about 25% of all adult knee problems and its non-specific complaint has multiple causes and risk factors. Objective: This study aims to evaluate the role of magnetic resonance imaging (MRI) in diagnosing different diseases that cause pain in the front of the knee. Patients and methods: A cross sectional study of forty eight patients with history of anterior knee pain. All patients were referred from the outpatient clinic of orthopedic surgery, Zagazig University Hospitals. This work was performed at the MRI unit of Radiodiagnosis Department, Zagazig University Hospitals. Results: The mean age of the studied group was 37.35±13.78 years. Visual Analog Scale (VAS) was (4.62±1.16) with more than half (56.2%) of cases having right sided pain. Most presenting symptoms was isolated anterior knee pain (62.5%). The frequency distribution of all MRI findings in all patients showed that 58.3% of the studied group had patellar tilt, 33.3% had patellar chondromalacia or patellofemoral instability, and 20.8% of cases had patellofemoral osteoarthritis. Conclusion: MRI is proven to be the technique of choice in differentiation between various knee pathologies that cause AKP in different age groups due to its safety. Also, MRI has the ability to detect the different grades of some knee pathologies as trochlear dysplasia, chondromalacia patella or factors that may predispose to them.

Objectives: The Patellofemoral joint (PFJ) is a complex joint structure with high functional and biomechanical requirements. The purpose of this study is to evaluate cause of patella-femoral joint instability with in-depth evaluation of influence of anatomical risk factors (AF), measurements and anatomical relationships of the patellofemoral joint and various pathologies causing medial patellofemoral ligament (MPFL) injury that contributes to the patellar maltracking using 1.5 Tesla magnetic resonance imaging. Materials and Methods: The present prospective study is carried out at department of radiology, shri M P Shah Medical College, Jamnagar. This is study of total 50 patients carried out in 12-month duration from July 2019 to June 2020, in which 50 patients aged between 8 - 68 years selected as study group presented with complaint symptoms of patellofemoral instability, knee pain and maltracking were examined and identified by an orthopaedic surgeon. Patients with the clinical suspicion of a PFJ maltracking were selected for subsequent MRI examination. Results: The age distribution in our study was in range of 8 years to 68 years with maximum population within 31 to 40 years range, 66 % were male and 34 % female. Their trochlear depth, sulcal angle, trochlear facet asymmetry, lateral inclination angle was found abnormal in 18 cases (36%), 8 (16%) showed patellar alta and 7 (14%) patella baja. Lateralization of patella (> 6 mm) was noted in 18 patients (36%), Medial patellofemoral ligament injuries were seen in 16 (32%) patients on MRI and kissing contusion 10 (20%) patients. A detailed understanding of the anatomy and pathology of the anterior knee compartment is essential for proper imaging interpretation and treatment management. Conclusion: Magnetic resonance (MR) imaging has been established as the method of choice, showing high accuracy in patellofemoral joint abnormalities. The present study aims to explore the role of MR imaging in diagnosing the various disorders located in anterior compartment of knee. Keywords: Joint instability, Patellofemoral joint, MPFL, MR imaging/diagnosis.

“…6,7 The treatment of ligamentous injuries and chondral lesions is best judged by MR imaging. 8 The Medial Patellofemoral Ligament (MPFL) is the primary restraint against lateral dislocation of the patella. 9,10,11 Conlan et al 9 reported that the MPFL provided 53% of the total medial restraining force.…”

BACKGROUND Recurrent patellar instability is not an uncommon entity with acute patellar dislocation accounting for 2% to 3% of all knee injuries and is the second most common cause of traumatic knee haemarthrosis. Based on recent biomechanical studies, among the medial patellar stabilisers the Medial Patellofemoral Ligament (MPFL) is considered as the primary restraint against lateral dislocation of the patella. MATERIALS AND METHODS This is an observational study. 25 patients (15 males and 10 females) with recurrent patellar dislocation were operated with MPFL reconstruction with tendon graft and bio screw. Their clinical outcome was measured with respect to pre-op, 3 months post-op and 6 months post-op Kujala score. SPSS software was used for analysis. RESULTS Pre-op mean Kujala score was 71.24 and 6 months mean Kujala score was 75.12. CONCLUSION This study demonstrates that clinical outcomes are good after isolated MPFL reconstruction, as evidenced by the Kujala score. Study findings correlate well with other previous studies done on MPFL reconstruction for recurrent patellar dislocation.
