Abstract Objective To study the correlations between gender, age, patellofemoral anatomic parameters and patellofemoral cartilage lesions after acute lateral patellar dislocation (LPD).Methods Between January 2015 and July 2021, the MRI data on 115 patients with clinically proved acute LPD treated in Shandong Provincial Corps Hospital of Chinese People’s Armed Police Force was retrospectively analyzed. The correlations between gender, age (adolescents (<18 years) and adults (≥18 years)), patellofemoral anatomic parameters (patellar height, tibial tuberosity–trochlear groove (TT-TG) distance and trochlear dysplasia) and articular cartilage lesions of the patella and lateral femoral condyle were statistically analyzed.Results The incidence of articular cartilage lesions of the patella and lateral femoral condyle was 46.1% and 27.0% after acute LPD, respectively. The incidence of articular cartilage lesions of the patella in the male group and female group was 58.7% and 37.7% respectively, compared with 34.8% and 21.7% for the lateral femoral condyle. There was significant difference in the incidence of articular cartilage lesions of the patella between the male and female groups (χ²=4.905, P=0.027). The incidence of articular cartilage lesions of the patella in the adult group and adolescent group was 57.1% and 37.9% respectively, compared with 36.7% and 19.7% for the lateral femoral condyle. There was significant difference in the incidence of articular cartilage lesions of the patella and lateral femoral condyle between the adult group and the adolescent group (χ²=4.2, P=0.04;χ²=4.156, P=0.042). The incidence of articular cartilage lesions of the patella was 52.6% and 32.4% respectively in the normal TT-TG distance group and elevated TT-TG distance group, compared with 32.1% and 16.2% for the lateral femoral condyle. There was significant difference in the incidence of articular cartilage lesions of the patella between the normal and elevated TT-TG distance groups (χ²=4.093,P=0.043). The incidence of articular cartilage lesions of the patella in the normal trochlea group and high-grade trochlear dysplasia group was 58.7% and 28.6% respectively, and that of the lateral femoral condyle was 39.1% and 14.3% respectively. There was significant difference in the incidence of articular cartilage lesions of the patella and lateral femoral condyle between the normal trochlea and high-grade trochlear dysplasia groups (χ²=7.269, P=0.007; χ²=6.034, P=0.014). The incidence of articular cartilage lesions of the patella in the normal patellar height group and patella alta group was 48.4% and 43.4% respectively, compared with 30.6% and 22.6% for the lateral femoral condyle.Conclusions Adults and patients with normal trochlea are more vulnerable to articular cartilage lesions of the patella and lateral femoral condyle after acute LPD. Males and patients with normal TT-TG distance are more vulnerable to articular cartilage lesions of the patella after acute LPD.
