Objective To analyze the diagnostic efficiency of various multidimensional tibial tuberosity(TT)parameters in patellar instability,revealing their clinical applicability.Methods Patients diagnosed with patellar instability who underwent knee joint CT scans at Ningbo Hangzhou Bay Hospital from January 2020 to January 2023 were included as the observation group.A control group was randomly selected from patients who underwent knee joint CT scans during the same period but were excluded for patellar instability.Each group comprised 45 cases.Patient data were collected,and the clinical diagnostic efficiency of various TT parameters was analyzed through logistic regression and ROC curve analy-sis.Results A total of 90 eligible patients were included,with 33 males and 57 females.There was no significant difference in gender distribution between the two groups,but the observation group had a significantly younger age with statistical significance(P<0.001).Logistic regression analysis showed that TT-TG,TT-RA,TT-TG/PL,and TT-TG/PTL related TT parameters were effective indicators for predicting patellar instability.At the same time,ROC curve anal-ysis indicated the diagnostic efficacy of the related TT parameters,with the AUC value of TT-TG/PL being 0.826,TT-TG 0.816,TT-RA 0.761,and TT-TG/PTL 0.769.Conclusion Multidimensional TT parameters,such as TT-TG,TT-RA,TT-TG/PL,and TT-TG/PTL,have good clinical value in predicting patellar instability.Given that a single quantitative indicator may not fully assess patellar instability,combining multiple dimensional TT parameters can provide a more comprehensive and precise evaluation,thereby offering early guidance for the diagnosis and treatment of patellar instability.
