Failure analysis of primary surgery and therapeutic strategy of revision surgery for complex tibial plateau fractures

PURPOSE: To analyze the cause of failure of the primary surgery for complex tibial plateau fractures and to define the therapeutic strategy of the revision surgery for the same. METHODS: Twenty-one cases with failure of primary surgery for complex tibial plateau fractures were treated in our hospital from January 2012 to September 2016. There were 13 males and 8 females with an average age of 39.4 years (ranged between 27 and 58 years). Patients presented with different types of complex tibial plateau fractures like Schatzker type V (n=9), VI (n=12), type 41.C1 (n=9), type 41.C2 (n=6), and type 41.C3 (n=6). The therapeutic strategy for revision surgery in individual patients was decided following careful analysis and accurate assessment of the causes of failure of the primary surgery. All the patients were followed-up with Rasmussen radiographic scores and Hospital for Special Surgery (HSS) knee scores. RESULTS: All 21 patients underwent clinical and radiological examination after a mean follow-up time of 32.6 months. The average time of fracture healing was 4.5 months (ranged between 3 and 6 months). During the last follow-up, the mean range of motion of knee extension was 2.3° and knee flexion was 123.8°. The mean radiological Rasmussen score was 15.6 points, with an overall success rate of 85.7%. The average HSS knee score was 84.3 points, with an overall success rate of 80.9%. CONCLUSION: The common reasons for the failure of primary surgery of complex tibial plateau fractures were inadequate experience of the surgeon, inaccurate diagnosis and management, improper selection of implants, and poor surgical techniques. The key factors to succeed revision surgery were adequate preoperative evaluation, accurate intraoperative procedures, and proper postoperative rehabilitation.
