Purpose: Primary osteoarthritis on the elbow is the result of the growth of osteophytes and contracture of the capsule. It often causes disability on joint motion and pain while exercising. As arthroscopy has developed, the arthroscopic diagnosis and treatment of the elbow have recently become more generalized as well. Therefore, we like to report on arthroscopy for treating elbow arthritis and its results. Materials and Methods: This study includes 23 cases of elbow arthritis that were seen between 2005 June to 2007 June and these patients didn't response to conservative treatment. From this we excluded 18 cases that underwent arthroscopic surgery and among these 18 cases, 6 cases underwent ulnar nerve transfer. The average observation time was 21.3 months and the average age was 48.4 years (range: 22-66 years). The pre and post operative pain was evaluated with using the Visual Analogue Scale (VAS) and functional evaluation was done with using the Mayo elbow Performance Score (MEPS) with the range of joint motion. Results: The VAS score at the last follow up was significantly decreased from 3.4 to 1.9 compare to the preoperative score. The range of joint motion was improved by 25 (0-40) to 8.5 (0-20) in extension and 101.7 (80-140) to 125.2 (85-140) in flexion (p<0.05). The MEPS always showed significant improvement by showing an increase from 65.4 (40-85) to 87.9 (55-100). However, 3 cases showed a decreased range of motion after the operation. One case showed ulnar nerve symptoms after surgery. Conclusion: An arthroscopic procedure can treat the pathologic processes associated with arthritis of the elbow and it was safe and effective in this series.

In previous studies, we performed joint animal studies and clinical trials between Yonsei University and Oryza Oil & Fat Chemical Co. Ltd. We have shown that coffee bean extract has potent anti-obesity and hypotriglyceridemic activities as well as beneficial effects on body fat reduction.In this study, the effects of coffee bean extract (100 mg/capsule) on body fat reduction were evaluated in overweight/obese women (body mass index of 25~30 $kg/m^2$ or body fat > 30%) not diagnosed with any type of disease. Subjects were randomly assigned to a coffee bean extract group (n=10) or placebo group (n=10). We measured anthropometric parameters, abdominal fat distribution by computed tomography and blood components before and after the 8week intervention period. After supplementation, the coffee bean extract group showed body weight (p=0.08), body mass index (p=0.06), hip circumference (p<0.05), and upper waist circumference (p< 0.01). In addition, after 8 weeks, the coffee bean extract group showed a significant decrease in abdominal internal fat area compared to 0 weeks (0 weeks : $155.8cm^2$; 8 weeks : $145.9cm^2$, ${\Delta}$ change : $-9.9cm^2$, respectively). However, there were no significant differences in lipid profiles or serological measurements between the coffee bean extract group and placebo group. The results of our human study demonstrated that coffee bean extract supplementation for 8 weeks has beneficial effects on reducing abdominal internal fat area as well as hip and waist circumferences.

Extra-skeletal chondroma, characterized by its lack of connection with the adjacent bone, includes synovial chondromatosis, intra-articular and para-articular chondroma, and soft tissue chondroma. Among them, the last two lesions are extremely rare. This is the case about 20-year-old soldier, who had complained of tenderness of the knee, pain and fullness during knee flexion and limitation of motion after a hard military training. We found a mass in the x-ray and MRI and resect the mass surgically, which was a $5.5{\times}4{\times}3$ cm size hard solitary mass. On microscopic finding, it was consisted of lobulated hyaline cartilage and outer fibrous capsule, and we ascertained it as para-articular chondroma. We experienced a case of para-articular chondroma in the infrapatellar fat pad of the knee joint and present its clinical, radiologic and pathologic findings with literature review.

Purpose: We describe a new technique of arthroscopic medial plication using pull-out suture with consideration of anatomical location of medial patellofemoral ligament for the treatment of acute or recurrent patellar dislocation. Operative technique: Under arthroscopic examination, sutures are passed through the medial capsule, at which medial patellofemoral ligament is located, from outside to inside of knee joint. Three guide wires are inserted from anterior surface of the patella to upper half of its medial border. Intraarticular portions of sutures are pulled out toward anterior surface of the patella through bony tunnels. Under appropriate tension, the sutures are tied after performing lateral retinacular release. Conclusion: As suturing medial patellofemoral ligament, this technique can maximize the effect of medial plication and can correct subluxation and tilt of the patella. It seems to be a minimally invasive, easy and effective method for the treatment of acute or recurrent patellar dislocation.

Purpose: The nonoperative outcome of elbow dislocations with associated radial head and coronoid fractures are often unsatisfactory because of chronic instability and stiffness from proloned immobilization, Therefore we managed these injuries with well programed surgical appproaches. Method: Ten patients with this injury were evaluated retrospectively from May 1998 to June 2004 after a minimum of 12 months. These injuries include elbow dislocation and associated fractures of both the radial head and the coronoid process. All ten patients were treated by one clinic operatively with similar scheduled surgical methods which started on the lateral side and terminated on the medial side of the elbow. Radial head and neck fractures were classified Mason types, as two and three types respectively with six and four cases and six cases were fixated. Coronoid process were fixated with screws anteroposterior directly or anchor suture in all cases, each type was classified one, two and three. where were three type one, four type two, and three type three were according to Regan and Morrey classification. Results: The outcome was three resulting in excellent, four good, two normaland and the remaining case was one poor according to the Mayo Elbow Performance score. At a terminal follow up, the range of motion of the elbow averaged flection contracture, $6^{\circ}(0{\sim}20^{\circ})$ and further flection, $129^{\circ}(115{\sim}140^{\circ})$. Two patients had complications requiring additional care. One, displaced coronoid process which was repaired with capsule and the other patient experienced, palsy of ulnar nerve and contracted elbow joint. Conclusions: Usage of early operation as the minimum injury of medial ligaments complex and the rigid fixation of fractures to prompt motion with our scheduled management for elbow dislocations with associated radial head and coracoid fractures provided excellent results.

Purpose : The purpose of this study was to verify the usefulness and feasibility of ultrasonographic imaging for the detection of the disorders of the surrounding supporting structure such as articular capsule, retrodiscal tissue and related ligaments, osteoarthritic evidence and associated disc displacement at the temporomandibular joint(TMJ) Materials and Methods : 20 patients(40 joints) with periodic lock and crepitations were investigated prospectively using 12 MHz array transducer. Ultrasonographic Imagings were assessed for osteoarthritic surface changes of condyle, extent of disc displacement and disorders of surrounding structures. Ultrasonographic images were compared with clinical investigations, conventional radiography and Dental Computed Tomographic scans. Results : In clinical and conventional radiography, osteoarthritic changes were diagnosed in 8 joints. Ultrasonographically 7 of the 8 osteoarthritic changes were diagnosed correctly. Sensitivity, specificity, and accuracy of ultrasonography in the osteoarthritic detections were 87.5%, 62.5%, and 67.5% respectively. About the detection of disc displacement, disc displacement were diagnosed in 21 joints clinically. Ultrasonographically 19 of the 21 disc displacements were diagnosed correctly. Sensitivity, specificity, and accuracy of ultrasonography in the osteoarthritic detections were 95%, 90%, and 92.5% respectively. when the disorders of supportive structure were figured out, the disorders of supportive structure were diagnosed in 18 joints clinically. Ultrasonographically 1 of the 18 the disorders of supportive structure were diagnosed correctly. Sensitivity, specificity, and accuracy of ultrasonography in the osteoarthritic detections were 5.5%, 4.5%, and 55% respectively. Conclusion : Ultrasonography is an relatively reliable diagnostic tool for the detection of disc displacement and some of osteoarthritic changes. But it's not an insufficient imaging technique for the detection of the disorders of the surrounding structure.

Purpose: This study examined the difference between the drainage volume, blood loss, transfusion rate, volume, and complications with or without an intra-articular (IA) tranexamic acid (TXA) injection among patients who underwent simultaneous bilateral total knee arthroplasty (SBTKA) with bilateral knee joint osteoarthritis, including patients who have contraindications of intravenous administration. Materials and Methods: Among patients who underwent SBTKA from April 2016 to December 2018, 139 patients injected with 3 g of TXA in each side through a drainage tube after joint capsule repair (group T), and 57 patients (group A) who underwent the procedure without TXA between October 2007 and August 2010 were tested. No significant difference in age and sex was observed between the two groups (p=0.572, 0.474). TXA was injected in patients with contraindications of intravenous administrations. Patients who underwent SBTKA with inflammatory arthritis were excluded from this study. The average amount of drainage, blood loss, transfusion rate, volume and daily average transfusion rate, and hemoglobin (Hb) change by the postoperative day were compared. Complications, such as deep vein thrombosis, pulmonary thromboembolism, myocardial infarction, cerebral infarction, and infection, were investigated. Results: The average total blood losses in groups A and T were 2195.32±1175.63 ml and 1145.09±382.95 ml, respectively, and the average total drain volume was 1,178.30±48.59 ml and 774.19±310.06 ml, respectively; both were significantly lower in group T (p=0.002, <0.001). The transfusion rates were 77.2% (44/57) and 0.7% (1/139), which were significantly lower in group T (p<0.001). The total average transfusion volume in groups A and T were 735.44±550.83 ml and 4.60±54.28 ml, respectively, which were significantly lower in group T (p<0.001). Hb tended to increase for three or four days after surgery in group A and group T. Regarding complications, deep vein thrombosis was encountered in two cases (1.4%), and pulmonary thromboembolism was noted in three cases (2.2%) in group T, but there were no cases in group A. No infections, cerebral infarction, or myocardial infarction occurred. Conclusion: In SBTKA, IA injections of TXA reduced the average drain volume, blood loss, transfusion rate, and volume significantly and did not increase the incidence of complications, even in patients with contraindications of intravenous administration.
