Purpose: The purpose of the present study was to evaluate the diagnostic efficacy of CT arthrography (CTA) in the assessment of various shoulder pathologies, compared with MR arthrography (MRA) and MRI with arthroscopic correlation. Materials and Methods: CTA in 84 patients, MRA in 70 patients, and MRI in 27 patients were obtained. A radiologist interpreted each image for 5 pathologies: Bankart, SLAP, Hill-Sachs lesion, full-thickness, and partial-thickness rotator cuff tear. Detailed arthroscopic reports were compared with CTA, MRA, and MRI. The sensitivity, specificity, predictive values, and accuracy were calculated. The agreement between each diagnostic modality and arthroscopy was calculated. Diagnostic efficacy was assessed by the areas under the receiver operating characteristic (ROC) curves. Results: The diagnostic values of all three imaging groups were comparable to each other for Bankart, SLAP, Hills-Sachs, and full-thickness cuff tear lesions, but those of CTA were lower than MRI and MRA for partial-thickness cuff tears. The areas under the ROC curves for CTA, MRA, and MRI were not significantly different for all pathologies, except for partial-thickness cuff tears. Conclusion: CTA was equally competent to MRA or MRI in demonstrating Bankart, Hill-Sachs lesions, SLAP, and full thickness rotator cuff tears but not as efficient in diagnosing partial thickness rotator cuff tears.

목적: 관절경적 회전근개 복원술의 임상 결과는 관혈적 복원술의 결과에 비견될 만큼 우수하다는 많은 연구들이 보고되고 있다. 그러나 복원된 건의 치유 상태에 대한 연구는 아직도 부족한 편이다. 본 연구에서는 관절경적 2열 고정술 후의 임상 결과와 건의 치유 상태를 전산화 단층 촬영 조영술을 이용하여 분석하였으며, 이러한 임상 결과와 건의 치유상태에 영향을 미치는 변수를 알아 보고자 하였다. 대상 및 방법: 관절경적 2열 고정술을 이용하여 회전근개 복원술을 시행받고 최소 1년 이상의 추시 관찰을 받은 환자 중 건의 치유 상태 확인을 위해 전산화 단층 촬영 조영술을 시행한 27명의 환자를 대상으로 하였다. 평균 연령은 57세였으며 남자 11명, 여자 16명이었다. 술 전 및 술 후 1년에 동통 점수, 관절 운동 범위, 전방거상력, 이환 기간, 그리고 여러 종류의 임상 점수를 측정하였으며, 수술 중 파열의 시상면 및 관상면의 크기, 이환 건의 범위를 측정하였다. 술 전 자기공명 영상 관절 조영술, 술 후에는 전산화 단층 촬영 관절 조영술에서 극상근 및 극하근의 위축정도를 분석하였으며 건의 연속성을 통한 건 치유 상태를 분석하였다. 건의 치유 상태는 치유, 재파열, 그리고 건의 연속성은 있으나 부분적인 조영제 침투가 보이는 불완전 치유의 3단계로 구분하였다. 또한 환자군을 전향적으로 추시하여 중, 장기적인 결과를 추시할 예정이다. 결과: 파열의 관상면 및 시상면 상 크기 중, 더 큰 것을 기준으로 파열의 크기를 분류하였고, 대상 환자 중 소파열이 1례, 중파열이 15례, 대파열 5례, 광범위 파열이 6례이었으며, 시상면에서의 평균 파열의 크기는 29.22 mm 이었다. 관상면에서의 크기는 평균 22.72 mm 이었으며, 술전 극상근 위축이 12례에서, 극하근 위축은 2례에서 관찰되었다. 술 후 1년에 동통 점수, 관절 운동 범위, 전방 거상력, 그리고 임상 점수는 모두 의미있게 호전되었으며 술 후 전체적인 환자 만족도는 80.38점이었다. 건의 치유 상태는 치유가 48.2%, 불완전 치유가 11.1%, 재파열이 40.7%이었으며, 근위축은 극상근이 8례, 극하근이 1례로 술 전에 비하여 약간의 호전을 보였다. 결론: 2열 고정술을 이용한 관절경적 회전근개 복원술은 양호한 임상 결과를 보였으며 전체적인 환자 만족도 또한 높았다. 그러나 건이 완전 치유된 경우가 48.2%로 비교적 낮아 이에 대한 연구가 더 필요하리라 사료된다.

Objectives: This study investigated the anti-osteoarthritic effects of Kyejiinsam-tang (hereinafter referred to KIT) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods: Anti-oxidative effects of KIT were measured by scavenging activities of DPPH, reactive oxygen species (ROS) and nitric oxide (NO). Scavenging activities of anti-oxidation in lipopolysaccharide (LPS)-treated RAW 264.7 cells were also measured for inhibitory effects against the production of inflammatory mediators (tumor necrosis factor-${\alpha}$, interleukin-$1{\beta}$, interleukin-6). Osteoarthritis was induced in rats by injecting MIA in the knee joint. Rats were divided into a total of 4 groups (n=6). The normal group were not treated at all without inducing osteoarthritis whereas the control group were induced for osteoarthritis by MIA and oral medicated physiological saline per day. The positive comparison group was injected with MIA and after 7 days, 2 mg/kg of Indomethacin. The experimental group was injected with MIA and after 7 days was medicated with 34 mg/kg of KIT. Indomethacin and KIT were orally-medicated for each substance a total of 4 weeks, once per day. Weight-bearing on hind legs was measured every week after MIA injection. At the end of the experiment (5 weeks after MIA injection), micro CT (computed tomography)-arthrography and histopathological examinations on the articular structures of knee joint were performed. The effect on inflammatory cytokines and immunological cells in synovial fluid was measured. Volume of cartilage was measured by micro CT-arthrography. Injury to synovial tissue was measured by H & E (hematoxylin and eosin), Safranin-O immunofluorescence. Results: 1. Cytotoxicity against hFCs was insignificant. 2. KIT showed the potent full term for DPPH. 1. NO was significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and ROS was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 2. IL-6 and IL-$1{\beta}$ were significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and TNF-${\alpha}$ was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 1. In hind legs weight-bearing measurement, level of weight increased. 2. Functions of liver and kidney were not affected. 3. IL-$1{\beta}$ was significantly reduced and TNF-${\alpha}$, IL-6 were also reduced but not significantly. 4. PGE2 (prostaglandin E2), LTB4 (leukotriene B4) were significantly reduced in the KIT group. 5. MMP-9 (matrix metalloproteinase-9), TIMP-1 (tissue inhibitor of metalloproteinases-1) and Osteocalcin were significantly reduced in the KIT group. 6. Destruction of cartilage on micro CT arthrography was reduced but had no significant differences. 7. Histopathologically, injury to synovial membrane of the KIT group was decreased and proteoglycan content of KIT group was increased. Conclusions: According to this study, Kyejiinsam-tang has inhibiting effect on the progression of arthritis in MIA-induced osteoarthritis rat. Kyejiinsam-tang has anti-oxidants and anti-inflammation effects, and is related to inhibiting the activity of inflammatory cytokine and injury of volume in cartilage.

Objectives This study was performed to investigate the effects of Saengkanggamchotang (SKT) on the monosodium iodoacetate (MIA) induced osteoarthritis in rats. Methods Osteoarthritis was induced by injection of MIA (50 ul, 60 mg/ml) into knee joints of rats. Rats are divided into a total of 4 groups (normal, control, positive comparison group, SKT treated group, each n=6). Normal group are not treated at all without inducing osteoarthritis whereas control group were induced for osteoarthritis by MIA and oral medicated with 20 ml of distilled water per day. Positive comparison group was injected with MIA and after 7 days, that was taken indomethacin (30 mg/kg/mouse). SKT treated group was injected with MIA and after 7 days that was taken SKT (30 mg/kg/mouse). Positive comparison group and SKT treated group were oral medicated for each substance a total of 4 weeks with one time per day. After experiments (from 1 week after injection of papain to 4 weeks elapsed), the functions of liver and kidney, Prostaglandin E2, inflammatory cytokine (IL-$1{\beta}$, IL-6, TNF-${\alpha}$), osteocalcin, TIMP-1, MMP-9 within serum. Knee joint structures were observed by H&E, safranin-O staining method, and amount of cartilage were measured by ${\mu}CT$-arthrography. Results 1) Hind paw weight bearing ability was significantly improved. 2) Functions of liver and kidney were not affected. 3) Prostaglandin E2, osteocalcin, TIMP-1, MMP-9 in serum were significantly decreased. 4) Inflammatory cytokine IL-$1{\beta}$ was significantly decreased, and IL-6, TNF-${\alpha}$ were decreased but had not significant. 5) In terms of histopathology, significantly reduced subsidence of cartilage and bone in H&E staining. And in Safranin O staining, proteoglycan content in synovial membrane was significantly increased compared with control group. 6) Destruction of cartilage on ${\mu}CT$-arthrography was significantly reduced. Conclusions Based on all results mentioned above, Saengkanggamchotang (SKT) is believed to be meaningful for suppressing the progress of osteoarthritis and its treatments.

Background: Repair of superior labral anterior to posterior (SLAP) lesion in patients older than 40 years is controversial. The purpose of this study was to evaluate clinical outcomes of arthroscopic repair of SLAP lesions between younger and older patient groups. Methods: We reviewed 50 patients with isolated type II SLAP lesions who underwent arthroscopic repair. Patients were divided into 2 groups: group 1 included 20 patients aged <40 years, and group 2 included 30 patients aged ${\geq}40years$. Functional outcome at the final follow-up was assessed using a visual analog scale for pain and satisfaction, American Shoulder and Elbow Surgeons form, Constant score, University of California at Los Angeles score, and periodic change in range of motion (ROM). Anatomical outcome was evaluated using computed tomography (CT) arthrography at least 1 year after surgery. Results: No significant differences in functional scores or postoperative ROM were observed between the 2 groups. In group 2, later recovery of ROM (forward flexion, p=0.025; internal rotation, p=0.034) and lower satisfaction score (p=0.06) were observed for atraumatic patients (n=16) compared to patients with traumatic injury (n=14). Fifteen patients in group 1 (15/17, 88%) and 21 patients in group 2 (21/26, 81%) demonstrated a healed labrum on postoperative CT arthrography, and this difference was not significant. Conclusions: The results of this study suggest that arthroscopic repair of type II SLAP lesions can yield good functional and anatomical outcomes regardless of age, if patient selection is adequate. However, the delay in ROM recovery and lower satisfaction, particularly in older patients without traumatic injury, should be considered.

Objectives : This study was carried out to know the anti-osteroarthritic effects of Bangkibokryeong-tang(Fanjifuling-tang(BBT)) on the papain-induced osteoarthritis C57BL/10 mouse. Methods : Osteoarthritis was induced by injection of papain(6 ${\mu}l$) into knee joint of mouse. Osteoarthritic mice were divided into 4 groups(normal, control, joins(R), BBT). The injection did not fit the normal group. A week later, after the injection of papain, control group was taken normal saline 200 ${\mu}l$, positive control group was taken joins(R)(100 mg/kg), treated group was taken extract of Bangkibokryeong-tang(Fanjifuling-tang(BBT))(400 mg/kg). After then, we examined hepatotoxicity, nephrotoxicity, inflammation cytokines, expression of inflammation factor mRNA, hemotology, histology through the micro CT-arthrography, and etc. Results : 1. Hepatotoxicity and nephrotoxicity have not expressed. 2. The levels of IL-$1{\beta}$, TNF-${\alpha}$, IL-6, MCP-1, Thromboxane B2, Leukotriene B4, Prostaglandin E2 in serum were significantly decreased. 3. In hematology, the levels of neutrophils and monocytes were significantly decreased. 4. The expression of inflammation factor mRNA like TNF-${\alpha}$ and IL-6, COX-2, iNOS-II were significantly inhibited. 5. In micro CT-arthrography, cartilage volume was less decreased. 6. The degree of osteoarthritis induced damage of joint of BBT group is low in histopathologic observation(hematoxylin&eosin(H&E), Safranin-O). Conclusions : According to this study, BBT has effect of anti-osteoarthritis. Further clinical research for the cartilage protective effect is necessary.
