[Elektronische Daten] [Tommaso Bonanzinga, Hui Zhang, Guan-yang Song, Jin Zhang, Cecilia Signorelli, Hua Feng] Purpose: Treatment of posterolateral corner (PLC) injury in the multiligament-injured knee is still controversial. The aim of this study was to investigate the clinical outcome of acute or sub-acute surgical repair of Type 1 and 2 PLC peel-off lesions in a multiligament setting. Methods: Mini-open direct repair of the PLC was performed in 13 patients. Combined PCL, ACL and MCL injuries were simultaneously managed. Telos valgus and varus stress radiographs at 30° of flexion with 150N load were used to investigate medial and lateral joint opening. Posterior stress radiograph with 150N load was used to investigate the function of the PCL. External rotational laxity was assessed with a dial test at 30° of knee flexion, and photographs were taken to measure angles. Anterior displacement was examined using the manual maximum test performed with a KT-1000 arthrometer. Results: A statistically significant reduction between pre- and postoperative laxity values was achieved for every test. Particularly, lateral joint opening side-to-side difference reduced from 10.3±4.0 to 1.0±3.2mm and external rotation reduced from 15±8° to 0°±6° more than that of the contralateral uninjured knee. The medial joint opening side-to-side differencereduced from 11.5±5.6 to 2.6±2.7mm in the 7 patients surgically managed for MCL lesion. The anterior tibial displacement side-to-side difference reduced from 14.0±5.0 to 3.0±5.0 mm in the 9 patients surgically managed for ACL lesion. The posterior tibial translation side-to-side difference reduced from 11.1±5.1 to 4.4±3.9mm in the 11 patients treated for PCL lesion. Conclusion: The main finding of the current study is that acute repair of Type 1 and 2 PLC peel-off injury proved to be an effective procedure to restore PLC function in a multiligament-injured knee. These data enabled the current literature with an effective treatment option to face such a complex and various scenarios such as multiligament-injured knee. Level of evidence: IV.
