    © 2022 The Royal College of RadiologistsAIM: The purpose of this study was to evaluate meniscal and tibiofemoral cartilage injury in patients with trochlear dysplasia (TD) and investigate whether there were correlations between TD grade and meniscal and cartilage injury. In addition, the relationship between TD and mucoid degeneration of the anterior cruciate ligament (ACL-MD) was investigated. MATERİALS AND METHODS: Magnetic resonance imaging (MRI) examinations of 133 patients with TD were included in the study. TD was graded (types A, B, C, D). The tibial tuberosity (TT)–TG distance was also measured. The ACL was assessed for ACL-MD. Both menisci were evaluated for the degeneration and tears. Medial–lateral tibial plateau (MTP–LTP), medial–lateral femoral condyles (MFC–LFC), and trochlear cartilage were examined for focal cartilage defect (FCD). RESULTS: ACL-MD was present in 42 of the patients with TD (31.6%). There was a significant positive relationship between ACL-MD and TT–TG distance. Meniscal tear was detected in 40 (30.1%) of all patients. FCD were detected in the tibiofemoral compartments in 41 (30.8%) of 133 patients. There was a significant positive relationship between the presence of FCD in the LFC and the type of TD (p<0.01). FCD was present in the LFC of all cases in the type D. A significant positive relationship was found between the TT–TG distance and the presence of FCD, especially in the anterior part of LFC (p<0.01). There was a significant relationship between the lateral trochlear cartilage defect and the type of dysplasia (p=0.037). CONCLUSİON: TD is a significant risk factor for ACL-MD, meniscal, and tibiofemoral cartilage injury.

    Patellar height: an important parameter in knee MRI associated with tendinopathy, quadriceps fat pad edema (QFPE), anterior cruciate ligament mucoid degeneration (ACL-MD), and lateral cartilage damage
    (2024-01-01) Atay M.; TOPRAK H.; YILMAZ T. F.; Sari L.; Balsak S.; UÇAN V.; Mehdi E.; TOPRAK, HÜSEYİN; YILMAZ, TEMEL FATİH; SARI, LÜTFULLAH; BALSAK, SERDAR; UÇAN, VAHDET
    Background: Some pathologies associated with abnormal patellar height have been reported in the literature. However, its relationship with some pathologies, such as anterior cruciate ligament mucoid degeneration (ACL-MD) and focal cartilage defect, has not been investigated. Purpose: To investigate the relationship between patellar height with patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and focal cartilage defect. Material and Methods: Magnetic resonance imaging of the knees of 261 patients were classified into three groups as normal, patella alta, and patella baja, and evaluated in terms of patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and focal cartilage defect. Results: There were 261 patients (140 men, 121 women; age range = 18–60 years; mean age = 30 ± 4.7 years). Of the 261 patients, 181 (69.3%) were normal, 56 (21.4%) were patella alta, and 24 were patella baja (9.1%). Patellar-quadriceps tendinopathy, quadriceps fat pad edema, and ACL-MD rates were significantly higher compared to the normal group (P <0.05). While a moderate positive correlation was found between patellar height shift and patellar-quadriceps tendinopathy and ACL-MD, there was a small correlation between patellar height shift and quadriceps fat pad edema. The rate of focal cartilage defect was significantly higher in the middle part of the lateral femoral condyle and lateral knee joint only in patella alta. Conclusion: The risk of patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and lateral focal cartilage defect is higher in patients with alta-baja. The radiologist should evaluate these pathologies more carefully, especially subtle ones, in patients with abnormal patellar height.
