Knee arthroscopic is basically making two small holes .5 to 1 cm in the knee and inserting a camera in 1 to visualize the knee and the injuries which are there and using micro-instruments through the other side in order to cut and stitch the issue which we identified into it. Knee arthroscopic is used in order to repair ligament injuries and this is a very easy manner by which ligament injuries can be reconstructed and return to normals can be offered to the patients at a reduced period of time
