Background: The blunted tip of a reusable with multiple uses can cause problems with the passing procedure in arthroscopic Bankart repair. This study assessed the advantage of Scorpion with a $70^{\circ}$ arthroscope in arthroscopic Bankart repair compared to hook typed suture passer. Methods: Scorpion in 19 patients, the hook type suture passer (conventional group) in 18 patients were used. All patients underwent the same procedure except for the type of suture passer used. Another different point of the procedure were telescopes and the number of portals used; three arthroscopic portals (posterior, anterorsuperiorlateral, and mid-anterior) and a $30^{\circ}$ arthroscope in the conventional group, but two portals and a $70^{\circ}$ arthroscope as well as the $30^{\circ}$ one in the Scorpion group. The surgery time and the surgical complications including an iatrogenic axillary nerve injury were recorded. Results: The Scorpion group showed a significant decrease in surgery time compared to the conventional group. In contrast to the conventional group, Scorpion provided an easy estimation of the exit of suture passing, no iatrogenic labral injury during the passing procedure with straight movement and the sharp tip of the knife installed. Iatrogenic supraspinatus injuries could be avoided when making an accessory anteosuperiorlateral portal due to the $70^{\circ}$ arthroscope. Conclusions: In arthroscopic Bankart repair, the use of the Scorpion suture passer and a $70^{\circ}$ arthroscope can reduce the surgery time, avoid unnecessary supraspinatus injury, and avoid iatrogenic axillary nerve damage through the relatively easy and precise suture passing and saving of the anterosuperior portal.

Arthroscopy is a valuable diagnostic and operative tool in equine and human orthopedics. The arthroscope is a difficult instrument to use and requires patience, practice, and persistence in order to obtain good results. This technique was found to be less traumatic than arthrotomy, invasiveness, rapid recovery and the feasibility of surgically correcting many arthropathies. The use of the arthroscope in the dog provides a new dimension in the study and diagnosis of joint derangements. The purpose of this report is to introduce the use of the arthroscope in the dog-more specifically, in the stifle of the dog. A diameter 2.7 mm fore-oblique viewing arthroscope, cold light source, video and video printer are used. With the fore-oblique viewing type it is possible to view directly as well as slightly to the side and the range of viewing can be increased by rotating the arthroscope around the object The scope is connected with a cold light source by means of a fiber-optic light guide. The stifle joint was flexed to 20~30$^{\circ}$. The joint were lavaged with lactated Ringer's solution during arthroscopic examination. Arthroscopy of the stifle was performed prior to arthrotomy in 1 dead dog and 4 healthy dogs, and other 3 dogs was performed only arthroscopic examination. In this study only the conventional approaches were used and in most cases it was possible to view all the intra-articular structures via the lateral infrapatellar approach. In the stifle joint, endoscopic observation was performed to find lateral femoral condyle, patella, medial femoral condyle, trochlear groove, tibia, fat, cranial cruciate ligament, caudal cruciate ligament lateral meniscus, tendon of long digital extensor muscle, medial meniscus, and medial collateral ligament Post-arthroscopic examination, the lameness had disappeared within 12~24 hours. Pain and swelling in the stifle joint had disappeared within 24~36 hours. Post-arthroscopic secondary infection was never encountered in the dogs. In conclusion, arthroscopic insertion technique in canine stifle joint using a diameter 2.7 mm 30$^{\circ}$ arthroscope was established and arthroscopical views of all anatomical structures in the normal stilfe joint were obtained through lateral infrapatellar portal.

Foraminal decompression using a minimally invasive technique to preserve facet joint stability and function without fusion reportedly improves the radicular symptoms in approximately 80% of patients and is considered one of the good surgical treatment choices for lumbar foraminal or extraforaminal stenosis. However, proper decompression was not possible because of the inability to access the foramen at the L5-S1 level due to prominence of the iliac crest. To overcome this challenge, endoscopy-based minimally invasive spine surgery has recently gained attention. Here, we report the technical skills required in unilateral extraforaminal biportal endoscopic spinal surgery using a $30^{\circ}$ arthroscope to enable foraminal decompression at the L5-S1 level. Two 0.8-cm portals were created 2 cm lateral from the lateral border of the pedicles at the L5-S1 level. After sufficient working space was made, half of the superior articular process (SAP) in the hypertrophied facet joint was removed using a high-speed burr and a 5-mm wide osteotome, whereas the remaining inside part of the SAP was removed using a Kerrison punch and pituitary punch. The foraminal ligamentum flavum should be removed to inspect the conditions of the L5 exiting root and disc. Removing of the extruded disc could decompress the L5 root. The extraforaminal approach using a $30^{\circ}$ arthroscope is considered a minimally invasive alternative technique for decompressing foraminal stenosis at the L5-S1 level that preserves facet stability and provides symptomatic relief.

The development of good quality small-diametered arthroscopes and refined arthroscopic techniques has contributed to the improvement of the subtalar arthroscopy. The therapeutic indications are synovectomy, removal of loose bodies, debridement and drilling of osteochondritis dissecans, excision of subtalar impingement lesions and osteophytes, lysis of adhesions for post-traumatic arthrofibrosis, removal of a symptomatic os trigonum, calcaneal fracture assessment and reduction, and arthroscopic arthrodesis of the subtalar joint. The subtalar arthroscopy can be done in supine position using thigh holder or in lateral decubitus position. The arthroscope generally used is a 2.7-mm 30 degrees short arthroscope. Noninvasive distraction with a strap around the hindfoot can be helpful. Usually anterolateral, middle and posterolateral portals are utilized for inspection and instrumentation within the joint. Twoportal posterior subtalar arthroscopy in prone position can be performed as well with 4.0-mm 30 degrees arthroscope, depending on the type and location of the subtalar pathology. The subtalar arthroscopy is a technically demanding procedure, which requires proper instrumentation and careful operative technique. Possible complications are nerve damage and persistent wound drainage.

Visually guided irrigation and lysis(VGIL) using temporomandibular joint(TMJ) arthroscope is useful for decreasing pain and increasing the functional mobility of TMJ. Also it demonstrated similar effectiveness comparing with arthrocentesis. Arthroscopy permits intracapsular inspection that is imperative not only for identification of morphological characteristics of joint space, but also for adequate irrigation and lysis of specific joint space. Conventional 2.3mm diameter arthroscope with 2.7mm catheter was too wide. So it was traumatic and uncomfortable to manipulate on temporomandibular joint space, especially on TMJ internal derangement patient with reduced space. We report our clinical experience on 6 TMJ closed lock patients who were treated with new 1.2mm fiberscope at Chung Hoon Dental Clinic between March 2003 and August 2003. Also we present clinical advantage & disadvantage of new system with literature review.

Background: The aim of this study was to evaluate clinical experience with arthroscopic debridement for septic arthritis of the shoulder joint and to report on our patient outcomes. Methods: The retrospective analysis included 36 shoulders (male:female, 15:21), contributed by 35 patients (mean age, 63.8 years) treated by arthroscopy for septic arthritis of the shoulder between November 2003 and February 2016. The mean follow-up period was 14.3 months (range, 12-33 months). An additional posterolateral portal and a 70° arthroscope was used to access the posteroinferior glenohumeral (GH) joint and posteroinferior subacromial (SA) space, respectively. Irrigation was performed with a large volume of fluid (25.1±8.1 L). Multiple suction drains (average, 3.3 drains) were inserted into the GH joint and SA space and removed 8.9±4.3 days after surgery. Intravenous antibiotics were administered for 3.9±1.8 weeks after surgery, followed by oral antibiotic treatment for another 3.6±1.9 weeks. Results: Among the 36 shoulders, reoperation was required in two cases (5.6%). The average range of motion achieved was 150.0° for forward flexion and T9 for internal rotation. The mean simple shoulder test score was 7.9±3.6 points. Nineteen shoulders (52.8%) had acupuncture or injection history prior to the infection. Pathogens were identified in 15 shoulders, with Staphylococcus aureus being the most commonly identified pathogen (10/15). Both the GH joint and the SA space were involved in 21 shoulders, while 14 cases involved only the GH joint and one case involved only the SA space. Conclusions: Complete debridement using an additional posterolateral portal and 70° arthroscope, a large volume of irrigation with >20 L of saline, and multiple suction drains may reduce the reoperation rate.

목적: 관절경하 후방 십자 인대 재건술시 지혈대의 필요성에 대한 언급된 문헌이 없어 지혈 대 없이 시행하는 본원의 관절경하 후방십자인대 재건술 결과 및 술기에 대해 보고하고자 한다. 대상 및 방법: 1998년 1월부터 2003년 5월까지 본원에서 후방십자인대 손상으로 관절경을 시행한 75례중 외측 측부인대 및 후외측 측부인대와 같은 동반손상으로 인해 관절외적 시술로 지혈대를 시행한 환자 16례와 술후 추시관찰이 12개월 이하인 10례를 제외한 49례의 단독 후방 십자 인대 손상 환자를 대상으로 하였고 자가 골-슬개건-골을 이용하여 재건한 경우 13례, 동종 골-슬개건-골을 이용하여 재건한 경우 19례, 동종 아킬레스 건을 이용하여 재건한 경우 17례였다 평가방법은 49례를 Lysholm knee scoring scale을 이용하여 비교하였다. 결과: 지혈대 없이 관절경하 후방 십자 인대 재건술을 한 경우 수술시간은 평균 105분 소요되었으며, 출혈로 인해 시야가 혼탁하여 지혈대를 사용한 경우는 없었다. 모든 환자에서 수술 부위의 부종, 국소 종창, 울혈, 환부 감염등은 관찰되지 않았다. Lysholm knee scoring scale을 이용한 평가 결과는 자가 골-슬개건-골을 이용한 경우는 평균 74점(fair) , 동종 아킬레스 건을 이용한 경우 75점(fair) , 동종 슬개건-골을 이용한 경우는 76점(fair)였다 결론: 관절경하 후방십자인대 재건술시 지혈대를 사용하지 않아도 수술에 어려움은 없으므로 지혈대 없이 재건술을 시행함으로써 지혈대로 인해 야기되는 합병증을 방지할 수 있을 것으로 생각된다.
