Treatment of transverse patellar fractures: a comparison between metallic and non-metallic implants

INTRODUCTION: Several methods of transverse patellar fixation have been described. This study compares the clinical outcome and the occurrence of complications of various fixation methods. SOURCES OF DATA: The databases PubMed, Web of Science, Science Direct, Google Scholar and Google were searched. AREAS OF AGREEMENT: A direct comparison between fixation techniques using mixed or non-metallic implants and metallic K-wire and tension band fixation shows no significant difference in clinical outcome between both groups. Additionally, studies reporting novel operation techniques show good clinical results. AREAS OF CONTROVERSY: Studies describing the treatment of patients using non-metallic or mixed implants are fewer compared with those using metallic fixation. GROWING POINTS: A large variety of clinical scoring systems were used for assessing the results of treatment, which makes direct comparison difficult. AREAS TIMELY FOR DEVELOPING RESEARCH: More data of fracture treatment using non-metallic or mixed implants is needed to achieve a more balanced comparison.
