Abstract
The medial collateral ligament (MCL) and the posterior oblique ligament (POL) are 2 of the main structures of the posteromedial corner of the knee. The MCL is important for valgus stability, whereas the POL is important for rotational stability. In cases of high-grade injury (grade 3) or when conservative treatment has failed, surgical intervention should be explored. Reconstruction is typically recommended over repair; however, there is still no consensus in the literature on the best reconstruction technique. This Technical Note describes an anatomic reconstruction of the posteromedial corner using a tibialis anterior allograft for the MCL and a semitendinosus allograft for the POL in the setting of a high-grade medial knee injury.
