Abstract :Background: Considering the critical role the anterior cruciate ligament insert ignore into journalissuearticles values(ACL); plays in knee biomechanics, it is a logical hypothesis that ACL reconstruction insert ignore into journalissuearticles values(ACLR); will have positive effects on knee kinematics, and stability. Our objective was to investigate the effect of single-bundle ACLR on patellar height, and patellofemoral balance radiologically and clinically. Methods: In this prospective study, 87 patients operated with hamstring autograft-used single-bundle ACLR were analyzed. History of dislocation, stability-related physical examination findings, Tegner-Lysholm Knee Scoring Scale, and Kujala Anterior Knee Pain Scale were used for functional assessment. All patients underwent pre-and post-operative magnetic resonance imaging and Insall-Salvati insert ignore into journalissuearticles values(IS); Index, Caton Deschamps Index, Blackburne-Peel Index, and Patella-patellar tendon insert ignore into journalissuearticles values(P-PT); angles were measured on T1-weighted sagittal section images. Results: A total of 79 patients insert ignore into journalissuearticles values(90.8%); achieved excellent or good result, according to Tegner-Lysholm Knee Scoring Scale, and the patients\` postoperative 1st year mean Kujala Anterior Knee Pain Score was calculated as 90.4 insert ignore into journalissuearticles values(Range: 79.1 – 96.4);. On physical examination, increased passive patellar translation was observed in 2 patients insert ignore into journalissuearticles values(2.3%);, but the J sign was appeared to be negative in all the patients. While all patellar height indices decreased after reconstruction, only the decrease in IS index was statistically significant insert ignore into journalissuearticles values(p=0.007);. Moreover, the P-PT angle was found to be significantly lower after ACLR insert ignore into journalissuearticles values(p<0.001);. Conclusion: Our study is an essential step in demonstrating the relationship between anterior cruciate ligament reconstruction and patellar height. With single-bundle ACLR, sagittal balance improves, patellar height indices decrease, and patients\` susceptibility to patellofemoral instability may reduce.
