Following conventional arthroscopic examination, patients' body temperature and ECG will be monitored. At first, under anesthesia, ultra-fine needle scope is inserted to the joint space at the sites of anteromedial and anterolateral portals without incision . According to conventional arthroscopic examination, medial and lateral menisci and other structures such as ligament and articular cartilage will be observed. All subjects are recorded as images and movies in specific hard disc drive. Second, incisions will be place to create anteromedial and anterolatearal portals, then conventional scope will be inserted. Observation of subjects will be done with same manner. Stored images and movies in the disc drive will be kept secured place until analysis.
