The Use of Dual Reconstruction Plates for Failed Fixation of Patellar Fracture after Total Knee Replacement: A Case Report

Patellar fracture after total knee replacement (TKR) is one of the challenging problems in periprosthetic fracture. Open reduction with internal fixation (ORIF), as tension band wiring (TBW), usually required in cases with extensor mechanism disruption. However, many studies reported a high failure rate after using this technique. In this report, we presented an interesting case of periprosthetic patellar fracture after TKR with TBW failure that was successfully treated with double non-locking reconstruction plates fixation and TBW augmentation

To our knowledge, no information related to the correlation between perioperative surgical factors and post-SHA perioperative complications in these patients has been demonstrated. This study aimed to identify the predictive factors for post-SHA perioperative complications in patients with FIF-ITFx.Materials and methods: A total of 32 patients with FIF-ITFx who underwent SHA between 2010 and 2017 were retrospectively reviewed. All patients had been followed for 1 year postoperatively. Perioperative data and complication details related to fracture and treatment were collected. Predictive factors for post-SHA perioperative complications were analyzed via logistic regression analysis.Results: Two (6%) patients died after SHA during the admission period. Perioperative complications were found in 16 (50%) patients, including surgical (n=3, 9%) and medical (n=15, 47%) complications, respectively. By univariate analysis, age (P=0.043), American Society of Anesthesiologist (ASA) grade 4 (P=0.016), Charlson Comorbidity Index (CCI; P=0.014), lymphocyte cell count (P=0.064), and serum albumin level (P=0.146) were correlated with the perioperative complications. However, multivariate regression analysis showed that CCI was the only significant independent predictor for post-SHA perioperative complications in these patients (OR=1.87; 95% CI, 1.14–2.07, P=0.014).Conclusion: Our study showed that post-SHA perioperative complications in patients with FIF-ITFx are very common and predictable with a simple preoperative factor CCI. Therefore, special perioperative attention must be paid to patients with FIF-ITFx undergoing SHA and having multiple severe comorbid diseases or high CCI.
