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.
