Objective:To explore the correlation between posterior condylar angle(PCA)and clinical out-come of medial patellofemoral ligament(MPFL)reconstruction recurrent patellar dislocation.Methods:A total of 38 recurrent patellar dislocation(RPD)patients(39 knees)undergoing MPFL re-construction from July 2017 to July 2022 were included.The biases from femoral trochlear morpholo-gy were controlled by dividing these knees into two groups,the normal trochlea with 20 knees and trochlear dysplasia with 19 knees;then another two cohorts(PCA＜3.82 ° and PCA≥3.82 °)were grouped in each trochlea-divided group.Perioperative and last follow-up data were compared between the four groups.Results:There were no significant differences in gender,affected side,age,body mass index(BMI),Insll-Salvati index(ISR),tibial tuberosity-trochlea groove distance(TT-TG),sul-cus angle(SA),patellar tilt angle(PTA),lateral trochlear inclination(LTI),hospital stay and follow up period among the groups(P＞0.05).All the patients underwent MPFL reconstruction combined with lateral retinaculum release during an average of 31.3 months follow-up after the surgery.None of the patients had patellar dislocation or severe postoperative complications.Kujala scores,Lysholm scores,and Tegner scores were increased in all groups(P＜0.05),which shows no significant differ-ence between PCA-divided groups in the same trochlea group(P＞0.05).Conclusion:MPFL recon-struction does achieve satisfactory mid-term clinical outcomes for RPD,which is not impacted remark-ably by PCA.
