328 Patellar Height After Anterior Cruciate Ligament Rupture Reconstruction Using the Autologous Bone-Patellar Tendon-Bone Graft Technique in The Maltese Population

Abstract Aim The primary aim of this study is to determine whether there a change in patellar height after closure the tendon defect bone-patellar tendon-bone graft harvesting. secondary evaluate clinical and functional outcomes. Method A retrospective observational was conducted. Patients who were diagnosed with ACL injury underwent reconstruction using B-p-T-B technique from 2015 2020 included (56 patients). All patients same procedural steps centre. had pre- post-operative knee radiographs (antero-posterior lateral views). Caton- Deschamps Index used measure post-operatively. International Knee Documentation Committee-Subjective Evaluation Form assess outcome. Clinical outcome assessed by reviewing patient records. Results There pre-op index 0.995 +/- 0.144 (mean SD) post-op 0.948 0.150. With statistically significant decrease 0.048 0.131 (p value 0.009) found. null hypothesis (that no change) rejected therefore alternative (a height) accepted. mean IKDC-SKF score 76.851 15.015 (SD) ranging 40.2 100 Conclusions Performing B-pT-B technique, although predisposing decreased height, it does not increase incidence patella baja. An overall good achieved, 76.85. However, clear association between PF symptoms could be demonstrated.
