Background: The purpose of this study was to evaluate the effect of single blinded anterior intra-articular corticosteroid injection to the glenohumeral joint performed by short experienced clinicians in frozen state adhesive capsulitis patients. Methods: From March to June of 2013, among the patients who visited the shoulder outpatient clinic due to shoulder pain for 5-6 months and those patient diagnosed as frozen state adhesive capsulitis was selected. The diagnosis were based on base, first the global limitation of range of motion, defined as forward elevation <100, external rotation at side <10, internal rotation less than buttock, and abduction <70. Second, the patients had additional radiologic evaluations showing no major pathologies for such stiffness. Clinical outcome, were performed with pain visual analog scale (PVAS) and functional visual analog scale (FVAS), American Shoulder and Elbow Surgeons Shoulder score (ASES), preinjection and postinjection after 2-4 weeks. Finally 82-patients were enrolled. Mean age of the patients was 55.1 years and mean follow-up duration was 25.17 days. Results: The mean preinjection PVAS was 6.91 and postinjection was 3.11, there was 3.8 decreases from preinjection status (p < 0.001). The mean FVAS score showed 4.26 at preinjection and 6.63 afterwards (p < 0.001). The ASES score showed 27.89 increases after injection (p < 0.001). There were 64-patients (78.04%) who reported more than 3 points of decrease of PVAS, who could be judged as effective treatment. Conclusions: Single anterior glenohumeral steroid injection by short experienced clinicians to the patients with frozen state adhesive capsulitis has shown relatively high efficacy in clinical result evaluated by means of PVAS.

Background: This study aimed to compare the effectiveness of the pericapsular nerve group (PENG) block and intra-articular injection (IAI) of steroid-bupivacaine in the treatment of hip osteoarthritis (OA). Methods: After randomization, patients received either a PENG block or IAI under ultrasound-guidance. Clinical evaluations were recorded at baseline, day 1, and weeks 1, 4, and 8 post-intervention. The numerical rating scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Harris Hip Scale (HHS) scores, pain medication use determined by a quantitative analgesic questionnaire, and patient satisfaction were evaluated. Results: Sixty patients were included in this study. NRS scores improved significantly for both groups during the follow-up compared to pretreatment (P < 0.001), with better pain scores for the PENG group (P < 0.001) at day 1 with larger effect size (Cohen's d = 4.62), and IAI group at 4 (Cohen's d = 5.15) and 8 (Cohen's d = 4.33) weeks (P < 0.001). There was no significant difference in pain medication consumption (P = 0.499) and patient satisfaction (P = 0.138) between groups. Patients in the IAI group experienced significant improvement in HHS (Cohen's d = 2.16, P = 0.007) and WOMAC (Cohen's d = 1.02, P = 0.036) scores at 8 weeks compared to the PENG group. Conclusions: The ultrasound-guided PENG block provides effective pain relief which improves functionality and quality of life in hip OA patients up to 2 months. The PENG block can be considered an easy, safe, and useful alternative treatment modality for hip OA.

For the induction of arthropathy, 4% hydrogen peroxide ($H_2O_2$) was injected for 4 weeks into the intra-articular space of the 25 New Zealand white rabbits to damage articular cartilage. The verification of arthropathy induction and the effect of scan-bio laser treatment were determined by measuring superoxide dismutase (SOD) activity, by observing gross and histopathologic findings. The SOD activity increased by about 40% in arthropathy group, as compared to controls. Although SOD activity in arthropathy group was not significantly different from the 2-week group, it was significantly different from the 4-week control and treatment groups. There was also a significant difference between the 4-week control and treatment groups. Grossly, erosions formed on the articular cartilage surface, and the lateral femoral condyle was damaged in arthropathy group. In comparison, there was slight, but not significant, progression of the lesion in the 2-week control group, and no difference between the 2-week treatment and control groups. Conversely, severe erosions damaged the articular cartilage in the 4-week control group. Cartilage proliferation was seen in gross observations in the 4-week treatment group, suggesting a treatment effect. Histopathologically, there was slight articular surface damage and apoptosis in arthropathy group, and serious cartilage damage, despite slight chondrocyte proliferation, in the 4-week control group. By contrast, the 4-week treatment group showed chondrocyte replacement, with close to normal articular cartilage on the articular surface. There was significant cartilage proliferation with regeneration of the articular cartilage on the articular surface in the group treated with low-level laser, as compared to control group, when arthropathy was induced by $H_2O_2$ injections. Therefore, low-level laser was effective in the treatment of chemically induced arthropathy.

Background: We evaluated the need for arthroscopic capsular release (ACR) in refractory primary frozen shoulder (FS) by comparing clinical outcomes of patients treated with ACR and manipulation under anesthesia (MUA). Methods: We assessed patients with refractory primary FS, 57 patients (group A) who were treated with MUA and 22 patients (group B) who were treated with ACR. In group A, manipulation including a backside arm-curl maneuver was performed under interscalene brachial block. In group B, manipulation was performed only to release the inferior capsule before arthroscopic circumferential capsular release, which was carried out for the unreleased capsule after manipulation. Pain, range of shoulder motion, and American Shoulder and Elbow Surgeons score were recorded at 1 week, 3 months, 6 months, and 1 year after surgery. We compared outcome variables between treatment groups and between diabetics and non-diabetics and also evaluated the numbers of patients receiving additional intra-articular steroid injection. Results: Outcome variables at 3 months after surgery and improvements in outcome variables did not differ between groups. Group A showed significantly better results than group B in the evaluation of pain and range of motion at 1 week. Diabetics showed comparable outcomes to non-diabetics for most variables. Eleven patients required additional steroid injections between 8 to 16 weeks after surgery: 12.2% in group A, 18.2% in group B. Additional injections were given three times more often in diabetics compared to non-diabetics. Conclusions: MUA alone can yield similar clinical outcomes to ACR in refractory FS.

Background: The rise in national health care costs has emerged as a global problem given the ever-aging population and rapid development of medical technology. The utilization of interventional pain management has, similarly, shown a continued rise worldwide. This study evaluates the differences in the medical costs in the field of interventional pain treatment (IPT) between two countries: Korea and Japan. Methods: Korean medical insurance costs for 2019 related to pain management focused on IPT were compared to those of Japan. Purchasing power parity (PPP) was used to adjust the exchange rate differences and to compare prices in consideration of the respective societies' economic power. Results: The cost of trigger point injections in Japan was 1.06 times higher than that of Korea, whereas the perineural and intraarticular injection prices were lower in Japan. The cost of epidural blocks was higher in Japan compared to Korea in both cervical/thoracic and lumbar regions. As for blocks of peripheral branches of spinal nerves, the cost of scapular nerve blocks in Japan was lower than that in Korea, given a PPP ratio 0.09. For nerve blocks in which fluoroscopy guidance is mandatory, the costs of epidurography in Japan were greater than those in Korea, given a PPP ratio 1.04. Conclusions: This is the first comparative study focusing on the medical costs related to IPT between Korea and Japan, which reveals that the costs differed along various categories. Further comparisons reflecting more diverse countries and socio-economic aspects will be required.

Purpose: The purpose of this study is to induce artificial arthritis on rabbit TMJ by injecting collagenase. Materials and Methods: An experimental animal model of arthritis induced by surgical method or intraarticular injection of chemical agent like LDH, papain, ketorolac. Surgical method is complex and needs a long time in inducing arthritis. Intra-articular injection of chemical agent like LDH, papain, ketorolac is simple. But chemical agent like LDH, papain, ketololac needs multiple injections to induce arthritis and mechanism inducing arthritis was known. Collagenase destroys helical domain of type II collagen in extracellular matrix produced by chondrocyte and then induces arthritis. We injected collagenase (0.5, 1.0, 2.0 mg) into the temporomandibular joint of rabbit. In the control group saline was intra-articularly injected. The condylar cartilage, disk and synovia were histologically examined at 1, 2, 4, 6 weeks after the initiation of collagenase injections. Results: Four weeks after injection of 2.0 mg collagenase, we could see histologic change like arthritis. In other groups, we couldn't see arthritis-like change. Conclusion: In our study, we produce arthritis on temporomandibular joint of rabbit by using injection of collagenase in temporomandibular joint of rabbit. And this experimental osteoarthritis is a useful animal model.

목적: 양측 슬관절 퇴행성 관절염으로 동시에 시행하는 양측 인공 슬관절 전치환술(simultaneous bilateral total knee arthroplasty, SBTKA)의 정맥 투여 금기에 해당하는 환자를 포함하여 관절강 내 트라넥삼산(tranexamic acid, TXA) 투여 후 배액량, 실혈량, 수혈률, 수혈량 및 합병증 발생의 차이를 비교해 보고자 하였다. 대상 및 방법: 2016년 4월부터 2018년 12월까지 퇴행성 관절염으로 SBTKA를 시행하였던 환자 중 관절낭 봉합 후 배액관을 통해 관절강 내로 한쪽당 3 g의 TXA를 주입한 139명을 실험군(group T), 2007년 10월부터 2010년 8월까지 TXA를 주입하지 않고 수술하였던 SBTKA 환자 57명(group A)을 대조군으로 설정했다. 양 군은 나이, 성별에 따른 유의한 차이는 없었다(p=0.572, 0.474). TXA는 정맥 내 투여의 금기에 해당하는 환자들에게도 관계 없이 주입하였고 염증성 관절염으로 수술을 시행한 환자는 본 연구에서 제외시켰다. 각각 평균 배액량, 실혈량, 수혈률, 수혈량과 일 평균 혈색소의 변화 추이, 일 평균 수혈량을 비교하였다. 합병증으로 심부 정맥 혈전증, 폐색전증, 감염, 뇌경색, 심근경색 발생 여부를 조사하였다. 결과: 평균 실혈량은 group A와 group T에서 각각 2195.32±1175.63 ml, 1145.09±382.95 ml, 평균 배액량은 1178.30±484.59 ml, 774.19±310.06 ml로 group T에서 각각 유의하게 적었다(p=0.002, <0.001). 수혈률은 각각 77.2% (44/57), 0.7% (1/139), 전체 평균 수혈량은 각각 735.44±550.83 ml, 4.60±54.28 ml로 group T에서 각각 유의하게 적었다(p<0.001, <0.001). 혈색소는 group A, group T에서 각각 술 후 3, 4일째 증가하였다(p<0.001, 0.001). 합병증으로 심부 정맥 혈전증이 group T에서 2예(1.4%), 폐색전증이 3예(2.2%) 발생하였으나 group A에서는 발생하지 않았다. 감염, 뇌경색, 심근경색은 모두에서 발생하지 않았다. 결론: 동시에 시행하는 SBTKA에서 TXA의 관절강 내 주입은 TXA의 평균 배액량, 실혈량, 수혈률, 수혈량을 유의하게 감소시키며 정맥 내 투여 금기에 해당하는 환자들을 포함하여도 합병증 발생률이 높아지지 않는다.
