Purpose: We introduce a technique of all inside arthroscopic capsular imbrication and lateral release used to treat patellofemoral instability. Methods: With the arthroscope in the anteromedial portal for best viewing, the arthroscopic scissor is placed through superolateral portal for proximal to distal release. The release performed 5mm to 1cm from the edge of the patella. After completion of the procedure, with the arthroscope in anterolateral portal, we inserted 5mm cannula in superolateral portal and made working portal from superomedial portal. Medial reefing was performed with all inside technique by using curved needle of the spectrum suturing system and No. 1 monofilament PDS suture is passed through the superomedial portal percutaneously and retrieved through a superolateral portal. Conclusion: Several methods for arthroscopic patella realignment have been proposed, but they have consisted primarily of arthroscopically assisted techniques using a medial incision. We believe that our procedure is preferable to arthroscopically assisted methods commonly used, in that an incision is avoided and the vastus medialis obliqqus is not violated. Our technique is minimally invasive and is easy to control the tightness of the medial patellofemoral ligament (MPFL) under direct vision.

The current treatment of extensive meniscal injuries has resulted in numerous investigations and clinical trials to restore normal meniscal functions. A cryopreserved meniscal allograft transplantation is one of the successful methods available to restore the meniscus. All the procedures of 26 cases were performed in an minimal open fashion, though initial four cases were done with the aid of arthroscope. In all of the grafts, we used a bone bridge which was attached to meniscus for better stability and healing. Anterior cruciate ligament reconstructions were also performed simultaneously with the meniscal procedures. We attempted to minimize articular cartilage by employing so called the "Key-hole technique" for the medial meniscus transplantation. First, the meniscal cartilage bone bridge was shaped into a cylinder and a bone tunnel was made just beside the medial border of the anterior criciate ligament insertion of the recipient knee joint, and the bone bridge of the meniscal cartilage was push to press-fit. The inserted meniscal cartilage was sutured by the usually employed technique under arthroscopic control. The lateral meniscus was shaped different to the medial meniscus in that the bone bridge was semicylindrical and the bone trough was made beside the lateral border of the anterior criciate ligament insertion of the recipient knee joint. The meniscus was put into the bone trough and the leading suture was extracted anterior to the tibia and tied the knot. The inserted meniscus was sutured in the same manner as the medial meniscus transplantation. By the above described method, the authors were able to minimize the articular cartilage invasion and transplant the meniscus with relative accuracy.

In the patient who has intradural mass associated with spinal stenosis, if the operation for spinal stenosis is performed alone, the symptom may remain. We report with literature review that we achieved the successful outcome after simultaneous decompression of spinal stenosis and space occupying mass removal in the case of intradural and extradural compression. A 71-year-old female patient suffering from low back pain and radiating pain of both lower extremities admitted. In magnetic resonance imaging, spinal stenosis on L4-5 and spondylolisthesis on L5-S1 compressed dural sac and intradural space occupying mass on L4 level compressed. By posterior approach, decompression and interbody fusion were carried out. Then mass was removed with median durotomy. Pathologic diagnosis was schwannoma and the symptom was improved remarkably.

A 42 year old male was admitted for a bony mass on the posterior arc of the left $6^{th}$ rib, which was detected in a multiphasic health screening test. According to the chest computed tomography scan and bone scan, osteochondroma was suspected. He underwent VATS rib resection. There was no vessel or nerve injury. The patient was discharged without any complication on the $4^{th}$ post operative day. The pathological diagnosis was benign fibrous histiocytoma. Generally, posterolateral thoracotomy is needed for rib resection, but we found that there was no difficulty in doing this kind of surgery under a thoracoscopic approach, which has the advantage of better cosmesis.
