Double-bundle technique: endoscopic posterior cruciate ligament reconstruction using tibialis posterior allograft.

Abstract Recently, attention has been given to the double-bundle technique for treating the posterior cruciate ligament (PCL)-deficient knee. We present an arthroscopic PCL reconstruction using a double-bundle technique with 3-stranded tibialis posterior (TP) allograft that has not been described before. The anterolateral bundle of the PCL is reconstructed using 2-stranded TP allograft and the posteromedial bundle using 1-stranded TP allograft. Three-stranded TP allograft will be an alternative graft choice for PCL reconstruction.

MPP test in the diagnosis of medial patellar plica syndrome.

Abstract Clinical features of the symptomatic mediopatellar plica (MPP) are nonspecific and the diagnosis has been troublesome for orthopaedic surgeons. We present a diagnostic test for symptomatic MPP.

New technique for chronic posterolateral instability of the knee: posterolateral reconstruction using the tibialis posterior tendon allograft.

Posterolateral instability of the knee is known as one of the most challenging injuries. Although several procedures have been designed for the posterolateral instability, there is no gold standard management as yet. We present a technique for posterolateral instability of the knee using a tibialis posterior tendon allograft, which reconstructs the lateral collateral ligament and popliteal tendon with its attachment to the tibia. This can correct not only varus, but also external rotary instability.
