title: The use of an anterior incision of the meniscus for exposure of tibial plateau fractures requiring open reduction and internal fixation.
abstract: The purpose of this study was to examine the use of an anterior incision of the meniscus for exposure of tibial plateau fractures. We studied 27 fractures of the proximal tibia treated with open reduction and internal fixation (ORIF). There were nine unicondylar fractures (five A-O B2; four A-O B3) fixed with plates and screws and 18 bicondylar fractures (seven A-O C1; five A-O C2; six A-O C3) fixed with combination internal and external fixation. Length of follow-up averaged 26 months. All patients were treated with an anterior incision of the meniscus and retraction with the condyle. Of the 18 bicondylar fractures, nine severely displaced fractures were found to have peripherally detached menisci. Unicondylar fractures did not display this finding. After fixation, menisci were repaired at the periphery and sewn to the original anterior insertion. The repair begins posteriorly and advances the cartilage to ensure anatomic placement. There were four medial and 23 lateral menisci in this series. Ten patients underwent knee arthroscopy 6 months to 2 years post-ORIF as a routine procedure during hardware removal. All menisci were found to be healed to the periphery and were stable. There were no gross tears. In one patient, the anterior meniscal incision could be visualized. No patients developed mechanical symptoms either in postoperative rehabilitation or postoperative follow-up at a maximum of 6 years. All patients had > 125 degrees of motion. Less motion when compared with the normal knee was felt to be related to more complex fracture patterns. In conclusion, the anterior meniscal incision allows for excellent exposure of severe proximal tibia fractures. This technique allows for anatomic meniscal repair and early rehabilitation. Arthroscopic examination confirms peripheral meniscal healing. No patient experienced clinical symptoms of meniscal pathology.
