New hamstring fixation technique for medial collateral ligament or posterolateral corner reconstruction using the mosaicplasty system.
In this study, we describe a new hamstring fixation technique with a bone graft using the Mosaicplasty system for the reconstruction of the medial collateral ligament (MCL) or posterolateral corner (PLC) of the knee. In this technique, a cylindrical bone plug (6.5 mm in diameter, 15 mm in length) is harvested from the anatomical femoral attachment of the MCL or popliteal tendon using the Mosaicplasty system. After placing the autologous semitendinosus or gracilis tendon as a graft in the created bone socket, the bone plug is replaced over the graft. The graft is secured with a spike staple after appropriate tension is applied to the graft. This fixation technique can provide rigid and less invasive fixation, because the distance between the fixation sites can be shorter than that in the Endobutton technique. Compared to fixation with only a staple with no bone graft, the bone graft may enhance tendon to bone healing.
