We introduce a new arthroscopic partial meniscectomy technique using a three portals and a small skin hook retractor to remove unstable inferior leaf in horizontal meniscal tear that involved the anterior portion of the lateral meniscus. The patient is positioned for a standard knee arthroscopy. After careful estimation of the depth and extent of the cleft and stability of the superior and inferior leaves is done through the standard anteromedial portal, a small skin hook retractor is inserted through the standard anterolateral portal to raise the dominant superior leaf of anterior horn, then the unstable inferior leaf is excised with a 90o rotary punch and a motorized shaver through the extreme far anteromedial portal. This technique is useful method to remove unstable inferior leaf of anterior horn of lateral meniscus which is difficult to remove with a standard technique.

The potential of low cost, light weight, flexibility and solution-processability made polymer or perovskite based solar cells (PSCs) be the promising candidates for renewable energy sources. In PSCs, device performances such as short-circuit current density, open-circuit voltage, and fill factor are closely related to the device architectures, the transparent electrodes, and the interface properties between the electrodes and organic active layer. From this respect, numerous modifications of device architectures, and conducting polymers, and interface properties by inserting interfacial layers have been studied intensively for high-efficient PSCs. Here, we will introduce solutionprocessable interfacial layers to enhance cell-performances. As interfacial layers, we have investigated solution-processable graphene-based thin films as hole transporting materials for high-performance and stable PSCs. Reduced-graphene oxide (r-GO) was prepared using various and novel reductants and the resulting r-GO all showed the enhanced cell-efficiency and air-stability, and thus demonstrating a practical alternative to conventional PEDOT:PSS. These overall trials could be very important for low-cost, high efficiency, and all-solution- processed PSCs.
