Background: The purpose of this study was to compare the clinical outcome in patients aged less than 55 years who underwent arthroscopic tenodesis and arthroscopic repair for type 2 superior labrum anterior and posterior (SLAP) lesions. Methods: Between April 2008 and December 2014, surgery was performed on a total of 45 patients with isolated type 2 SLAP lesions. Arthroscopic repair was performed in 22 patients and arthroscopic tenodesis was performed in 23 patients. In both groups, the clinical outcomes at follow-ups were evaluated using the University of California at Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and visual analogue scale (VAS) score. Results: In both groups, the VAS scores for pain had improved significantly throughout the postoperative follow-up period. The VAS score showed a statistically significant difference at postoperative 3 and 6 months (p<0.05); however, there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). In both groups, the functional outcome was statistically improved postoperatively. In a comparison of the UCLA and ASES scores between the two groups, there was a statistically significant difference at postoperative 3 and 6 months (p<0.05), but there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). Conclusions: Based on the results of this and other studies, patients with isolated type 2 SLAP lesions showed better short-term clinical outcome with tenodesis than with repair. However, there was no difference between the two groups at the final follow-up.

Selective Optimization with Compensation (SOC), a concept defined by Baltes and Baltes, is known to predict successful aging. This study was conducted to find out which factors affect Korean elderly people SOC The data for this study were obtained from a survey conducted between March and May 2001, on a sample of middle-class male and female participants over 60 years old. Two hundred and fifty four completed questionnaires were used for final analyses. Descriptive statistics, t-test, ANOVA, Duncan test, Pearson correlations, multiple regressions, multiple response frequencies and sequential threshold methods were used to analyze the data. In order to measure successful aging, the Selective Optimization with Compensation Scale developed by Baltes, Baltes, Freud, and Lang (1996) was used. The SOC scale consists of four subscales, Elective Selection, Loss-based Selection, Optimization, and Compensation. The major findings are summarized in the following. First, the level of SOC by various socio-demographic variables was examined. It tuned out that health status is the most important variable in predicting SOC. Also important was satisfaction with family life. Second, significant correlations were found between SOC and duration of the marriage (negative), practicing a religion, health, and economic stability (all positive). Third, religion and health status affected SOC, but health was a stronger predictor Those who practiced a religion and were healthy had a higher score in SOC as a whole. Fourth, the participants were divided into three groups by their SOC score, and their idea.; of successful aging were compared. The top- and middle-score groups considered satisfaction with family life to be more important, whereas the bottom-score group regarded the social status as more important.

Background: The purpose of this study was to investigate the difference between two nailing approaches of intramedullary screw fixation, the retrograde nailing versus the anterograde nailing, on the radiological and clinical outcomes in patients with clavicle shaft fractures. Methods: From April 2002 to August 2014, we enrolled a total of 22 patients with clavicle shaft fractures to participate in this study. Twelve patients received retrograde intramedullary nailing and 10 received anterograde nailing. The average duration of follow-up was 12 months. In all the patients, we took follow-up radiographs of the anteroposterior and the axial views to assess the postoperative radiological outcomes. We measured the visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and the range of motion (ROM). Results: Clinically, we did not find a statistically significant difference in the retrograde group and the anterograde group in terms of the duration to bone union, the VAS score the ASES score and the ROMs. Radiologically, we found that the difference in the clavicle shortening of the affected arm and the unaffected arm did not show a statistically significant difference at the immediate postoperative assessment. we found that the difference in the clavicle shortening of the affected arm between the immediate postoperative and the final follow-up value did not show a statistically significant difference. Conclusions: We found that both the retrograde nailing and the anterograde nailing gave a favorable outcome for clavicle shaft fractures. Although we saw evidence of clavicle shortening after intramedullary screw fixation, this was not a factor that influenced clinical outcome.

Local drought in South Korea has recently increased interest in the efficient use of groundwater and then induces a growing need to introduce artificial recharge of groundwater that stores water in sedimentary layer. In order to evaluate the potential artificial recharge sites in the alluvial basins in Chungcheongnamdo province, an AHP (Analytical hierarchy process) model consisting of three primary and seven secondary factors was developed in this study. In the AHP model, adding candidate sites changes final evaluation score through a mathematical calculation process. By contrast ANN (Artificial neural network) model always provides an unchanged score for each candidate area. Therefore, the score can be used as a selection criterion for artificial recharge sites. It is concluded that the possibility of artificial recharge is relatively low if the score of the ANN model is less than about 1.5. Further studies and field surveys on the other regions in Korea will lead to draw out a more applicable ANN model.

Background: The purpose of this study is to compare the clinical outcomes of the control group and platelet-rich plasma (PRP) group among the patients who failed to respond to conservative treatment as outpatient-based therapy for rotator cuff tendinopathy, and to compare the clinical results of leukocyte-poor (LP) PRP and leukocyte-rich (LR) PRP. Methods: Inclusion criteria are (1) over 18-year-old, (2) patients with rotator cuff tendinopathy, no rotator cuff tear by radiologic diagnosis (ultrasonography or magnetic resonance imaging) within the last 3 months, and (3) not effective to conservative treatment for more than 1 month. Of the final 60 subjects, 33 patients in the exercise treatment group and 27 patients in the PRP injection group (LP-PRP, 13; LR-PRP, 14) were included. Clinical evaluation was carried out by assessing the outcomes of treatment using the Numeric Rating Scale pain score, the American Shoulder and Elbow Society (ASES) score, and the Constant score at baseline and at 3 and 6 months after the procedure. Results: There was a statistically significant difference in ${\Delta}ASES_{3months}$ ($ASES_{3months}-ASES_{first}$) score between the control and PRP groups (p=0.006). However, there was no statistical significance between LP-PRP and LR-PRP groups (p>0.05). Conclusions: This study showed that PRP injection was more effective than exercise therapy for the first 3 months. However, there was no difference between the LP-PRP group and the LR-PRP group. Regardless of the type of PRP, clinical application of PRP injection in patients with rotator cuff tendinopathy seems to be effective in early treatment.

This study is a methodological study that explains the procedure for verifying effectiveness in developing practical guidelines for cognitive programs suitable for dementia patients. Based on the development of evidence-based new clinical practice guidelines, a preliminary recommendation for the domestic dementia patient care guidelines was developed. The practical guidelines consisted of the final four types, and the content validity score of the configuration items was 0.87 to 1 point. In the sub-categories of field applicability, appropriateness score was 3.95 to 4.34 points, applicability score was 3.57 to 4.27 points, and predicted effect score was 3.84 to 4.22 points. Through the examination of the content validity and field applicability of experts, it was confirmed that the practical guidelines developed in this study can be used as the basis for establishing an intervention plan for dementia cognitive program managers engaged in clinical practice. In future studies should further facilitate the development of evidence-based treatment guidelines to select appropriate treatment activities for dementia patients.

Background: Subscapularis tendon insertion at the first facet has separate layers (deep and superficial). The purpose of this study is to evaluate postoperative clinical outcomes and radiological healing according to each layer of detachment in the first facet involving subscapularis tendon tear. Methods: Eighty-three patients who underwent arthroscopic repair due to First facet involving the scapularis tendon tear accompanying small to medium sized posterosuperior cuff tear were classified into three groups (group A: deep layer partial detachment, group B: deep layer complete detachment, but no superficial layer detachment, and group C: deep layer and superficial layer complete detachment). Subscapularis tendon healing was evaluated using computed tomography arthrogram and clinical result was evaluated using American Shoulder and Elbow Surgeons (ASES) shoulder score, Constant score and University of California Los Angeles (UCLA) shoulder score. Results: Retear rate of the subscapularis tendon was 2.2%, 18.2%, and 33.3% in group A, group B, and group C, respectively. These rates showed statistically significant difference among the three groups, which were classified by deep and superficial layer detachment in the first facet (p=0.003). Group A showed significant difference in subscapularis tendon healing compared with group B and group C (p=0.018 and p<0.001, respectively), but there was no statistical difference between group B and group C (p=0.292). Regarding clinical outcomes, there was no significant difference among three groups in ASES and UCLA score at final follow-up (p=0.070 and p=0.106, respectively). Conclusions: Complete detachment of deep layer may be related with retear occurrence regardless with detachment of superficial layer, but clinical outcome may not be related with each layer detachment in the first facet involving subscapularis tendon tear.

Purpose: To evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) for postoperative pain after surgery around ankle. Materials and Methods: We included 21 patients who performed an operation around ankle from 2009 to 2013. 4 times ESWT were applied to the patients who have tenderness more than visual analog scale (VAS) point 4. We evaluated the VAS at each sessions and final follow-up, and American Orthopedic Foot and Ankle Society ankle-hindfoot score (AFOAS) was checked at preoperative and final follow-up. Patient's satisfaction and complications were surveyed. Results: Preoperative VAS was mean 4.7, postoperative pain VAS was mean 6.0 at 4.5 months follow-up. The VAS after ESWT each session at 1, 2, 3 weeks and final follow-up were 4.8, 3.2, 2.3, 2.9, respectively. Mean final follow-up period was 9.4 months. Final VAS were significantly decreased (p<0.001). Final VAS were increased from VAS at last session of ESWT, however, not significant (p=0.189). AOFAS significantly improved from preoperative 60 to final follow-up 86 (p<0.001). Excellent was 12 patients (57%), good was 4 patients (19%), no change was 3 patients (14%) and poor was 2 patients (9%). 1 patient complained a dizziness and nausea during ESWT. Conclusion: ESWT for postoperative pain after ankle surgery shows satisfactory pain reduction in 76% of all patients without severe complication.

Purpose : The purpose was to evaluate the early result of revision of failed anterior cruciate ligament (ACL) reconstruction. Materials and Methods : From August 1997 to February 2002, this report presents the findings of 18 patients who had revision surgery for failed ACL reconstruction. There was an average of 39 $(7\~120)$months from index procedure to the time of revision. Allografts were used in 14 $(78\%)$cases and autografts were used in 4 $(22\%)$cases and the revision procedures were assisted by arthroscopic technique. The majority of chief complaints were instability in 16 $(89\%)$cases. Sixteen $(89\%)$ cases had 1 previous reconstruction, 2 $(11\%)$ cases had 2. Before and after revision, patients were evaluated by Lachman test, pivot shift test, KT 2000, radiographs, Lysholm score and HSS score and subjective satisfaction. Results : Average length of followup was 27 $(12\~60)$months. Preoperatively, all cases were positive in Lachman test and pivot shift test. After revision the majority of cases were negative. Objectively improving stability was confirmed by KT 2000 and all average KT 2000 was 7.75 $(3.5\~12.5)$mm preoperatively and 2.36 $(1.0\~6.0)$mm at final followup. Lysholm score and HSS score were also improved from 72.6 $(66\~77)$ and 72.5 $(68\~78)$ preoperatively to 89.2 $(80\~92)$ and 88.2 $(81\~92)$ at final followup. Most $(89\%)$ of patients were satisfied with their results. The most common causes of failed ACL reconstruction were malposition of femoral tunnel in 11 $(61\%)$cases. Conclusion : Arthroscopic revision ACL surgery with adequate graft for failed ACL reconstruction was successful in objectively and subjectively improving stability. However, considering the most common causes of failure after ACL reconstruction were errors in surgical technique, it is important that the primary ACL reconstruction should be performed with correct surgical technique.
