    Abstract:
    OBJECTIVES: The optimal treatment protocol for bicondylar plateau fractures remains controversial. Contrary to popular practice which favors a staged protocol in many high-energy fracture patterns, we have used early single-stage open reduction and internal fixation (ORIF) to treat these injuries whenever possible. The purpose of this study was to determine the complication rate and the functional and radiographic outcomes of this strategy. DESIGN: Retrospective cohort study and prospective data collection. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: One hundred one patients with 102 OTA/AO type 41-C bicondylar tibial plateau fractures were treated with early definitive ORIF, defined as nonstaged surgery performed within 72 hours from injury. A subset of patients was part of a longitudinal study and reported functional outcomes at 1 year. INTERVENTION: Early definitive ORIF. MAIN OUTCOME MEASUREMENT: Primary outcome: reoperation rate, defined as any surgery within 12 months after the index operation; secondary outcomes: quality and stability of radiographic fracture reduction; and functional outcome [Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and short musculoskeletal functional assessment (SMFA)]. RESULTS: Nonstaged operative treatment of bicondylar plateau fractures was performed in 91.3% of the fractures during the study period. For those, early definitive ORIF (surgery within 72 hours from injury) was performed in 82.3% fractures. Mean time from injury to ORIF, for closed fractures, was 29.8 hours. Sixteen (15.7%) fractures, which were treated with early definitive ORIF, required an additional surgical procedure within 12 months. Complications included wound infection requiring surgical management, compartment syndrome requiring fasciotomies, nonunion, early fixation failure, and implant removal for discomfort. The reoperation rate was 12.7% if implant removal was excluded. At least 3 of the 4 radiographic criteria used to assess the adequacy of reduction were achieved in 95.1% of cases, and all 4 criteria were met in 59.8% of fractures. The Physical Component of the SF-36 at 12 months was 42.6, which is comparable to values reported in previous studies for operative treatment of bicondylar plateau fractures. CONCLUSIONS: In a model where surgery is performed without delay by experienced orthopaedic trauma surgeons, a large proportion of bicondylar tibial plateau fractures can be safely treated with early definitive ORIF. Early surgery was associated with satisfactory postoperative radiographic reductions. LEVEL OF EVIDENCE: Therapeutic Level IV.
