Purpose: The aim of this study wasto evaluate the comparison of CT arthrography and ultrasonography, confirmed by the arthroscopic finding in patients with rotator cuff disease. Materials and Methods: We evaluated fifty seven patients with rotator cuff disease underwent CTA and arthroscopy, and twenty eight patients had taken ultrasonographyadditionally. The diagnostic value and prediction for tear size between CTA and ultrasonography were evaluated, as compared to arthroscopic findings. Results: CTA showed a sensitivity of 86.2% and a specificity of 100% in full thickness tear ofsupraspinatus, a sensitivity of 58.3% and a specificity of 87.8% in partial-thickness tear. CTA demonstrated good diagnostic value for full thickness tear, but there was relatively lower value for partial-thickness tear. Ultrasonography showed a sensitivity of 84.6% and a specificity of 86.7% for diagnosing in full thickness tear, a sensitivity of 84.6% and a specificity of 73.3% in partial-thickness tear. Ultrasonography provided good diagnostic value, but, there is lesser accurate result for prediction of tear size. Conclusion: CTA showedgood diagnostic tool of detection full-thickness tear of rotator cuff disease and predicting of tear size. Comparing with ultrasonography, CTA was inferior for detection of partial-thickness tear, but, provided better estimation for tear size.

Background: The present study was undertaken to evaluate the relationship between location of the rotator cuff tear and shape of the subacromial spur. Methods: Totally, 80 consecutive patients who underwent arthroscopic repair for partial thickness rotator cuff tear were enrolled for the study. Bigliani's type of the acromion, type of subacromial spur, and location of partial thickness tear of the rotator cuff were evaluated using plain X-ray and magnetic resonance imaging. We then compared the groups of no spur with spur, and heel with traction spur. Results: Of the 80 cases, 25 cases comprised the no spur group, and 55 cases comprised the spur group. There was a significant difference in type of tear (p=0.0004) between these two groups. Bursal side tears were significantly greater (odds ratio=6.000, p=0.0007) in the spur group. Subjects belonging to the spur group were further divided into heel (38 cases) and traction spur (17 cases). Comparing these two groups revealed significant differences only in the type of tear (p=0.0001). Furthermore, the heel spur had significantly greater bursal side tear (odds ratio=29.521, p=0.0005) as compared to traction spur. Conclusions: The heel spur is more associated to bursal side tear than the traction spur, whereas the traction spur associates greater to the articular side tear.

Partial-thickness rotator cuff tear (PTRCT) is not single disease entity but one phase of disease spectrum. Symptoms of PTRCT vary from being asymptomatic to severe pain leading to deterioration in quality of life. Pathogenesis of degenerative PTRCT is multifactorial. Whereas articular sided PTRCT is usually caused by internal causes, both internal and external causes have important role in bursal sided PTRCT. A detailed history, clinical examination and magnetic resonance angiography are used in the diagnosis of PTRCT. Treatment of PTRCT is chosen based on age, demands of patients, causes and depth of tear. In most patients, non-operative treatment should be initiated. Whereas debridement can be done for less than 6 mm of articular sided PTRCT and in less than 3 mm of bursal sided PTRCT, repair techniques should be considered for higher grade PTRCT than that. Although the effect of acromioplasty is not clear, acromioplasty may be performed when the extrinsic causes appear to be the cause of tear. Either transtendon repair technique or repair after tear completion provided satisfactory clinical outcomes in treatment of articular sided PTRCT.

Purpose : To introduce arthroscopic partial meniscectomy fur bucket handle tear of medial meniscus using posteromedial portal, which is superior to arthroscopic partial meniscectomy using standard anterior portals commonly used. Method : After arthroscopic examination of the knee, we reduce the torn meniscus, advance the arthroscope into posteromedial compartment under arthroscopic visualization, we make posteromedial portal with reexamination of the compartment and perform arthroscopic partial meniscectomy. Conclusion : With the technique of arthroscopic partial meniscectomy using standard anterior portals, accurate partial meniscectomy can not be done because of inadequate visual field, associated meniscal injuries of posterior horn and cartilage lesion of posterior aspect of the medial femoral condyle can be missed, commonly posterior cruciate ligament can be injured and artificial damage to weight bearing surface of medial femoral condyle is possible. An arthroscopic partial meniscectomy using posteromedial portal is an excellent method fur bucket handle tear of medial meniscus.

Forty-nine partial thickness rotator cuff tears underwent arthroscopic debridement or repair, and were followed up for a minimum of two years. Follow-up evaluations of the results were completed using a detailed functional questionnaire which was comprised of a rating of the UCLA shoulder scale and return to the previous sports activity and job. The average age of the 49 study patients was 46.5 years(range, 14 to 67 years). The patients were divided into four groups on the basis of the onset of the patient's symptoms. Thirty-five patients(72%) had partial tearing only on the articular surface, six(12%) on the bursal surface, and eight(16%) on both surfaces. Group I consisted of 21 patients with an average age of 56.7. Partial tearing in group I was attributed to the impingement syndrome. In group II, partial tearing of the rotator cuff was related to the anterior instability of the shoulder. This group included 9 patients with an average age of 27.9. In group III, all of the 8 patients were overhead athletes with an average age of 21.8. In this group, no isolated instances of significant trauma were related to the development of the shoulder pain. In group IV, 11 patients noted that a significant traumatic event preceded the onset of their pain. The average age of the patients was 34.9. Overall, 82% of the patients demonstrated satisfactory results and 18% revealed unsatisfactory results. The worst UCLA score and rate of return to the prior activity was noted in group III. In conclusion, partial thickness rotator cuff tear can be caused by subacromial impingement, instability, repetitive microtrauma, and macrotrauma. Arthroscopic debridement of partial tear of the rotator cuff provides a favorable outcome except in overhead athletes.

Purpose : To evaluate the diagnostic efficiency of the subacromial bursoscopy with glenohumeral air infusion technique for detection of the full thickness tear which we used to think as a partial thickness tear, because it was hidden by bursal tissue. Materials and methods : We chose 65 cases and divided them into 2 groups. The group I was 18 cases with partial thickness rotator cuff tears on glenohumeral arthroscopic evaluation, and the group 2 was 37 cases with full thickness rotator cuff tears which were repaired. We inflated the glenohumeral Joint with 50-100ml of air and observed air bubble leakage simultaneously on bursoscopy. Results : In group I, we could detect air leakage in 3 cases and found that it was full thickness tear. In group II, 2 cases revealed too much air leakage proved that it was incomplete repair and was in need of additional suture. Conclusion : Air infusion technique is though to be a valuable method in differentiation between the partial and full thickness tear and for evaluation of the security of the repair.

Background: The aims of this study were (1) to examine the footprint of the subscapularis tendon using the traditional posterior portal and $30^{\circ}$ arthroscope by simple internal rotation of the arm during surgery, and (2) to classify the pattern of a subscapularis partial-thickness tear. Methods: This study analyzed a total of 231 patients with a partial-thickness subscapularis tear from 550 consecutive patients undergoing an arthroscopic operation who had a visualization of the subscapularis tendon footprint by internal rotation of the arm. First, the patients were classified into four categories according to the tear pattern: (1) stable lamination, (2) unstable lamination, (3) avulsion, and (4) laminated avulsion. Randomized arthroscopic videos were reviewed blindly by two independent orthopedic surgeons. The pattern of the tear of the subscapularis at the neutral position and after internal rotating the arm were assessed and compared with the treatment decision (level IV case series). Results: Stable lamination, unstable lamination, avulsion, and laminated avulsion were observed in 9.1% (n=21), 20.8% (n=48), 41.1% (n=95), and 29.0% (n=67) of cases, respectively. In 145 out of 231 cases (62.8%), the decision was changed after inspecting the footprint after internal rotation of the arm, and the treatment method was changed in 116 (50.2%) cases. Conclusions: In a subscapularis tendon partial-thickness tear, inspecting the footprint of the subscapularis tendon is essential to diagnosing and deciding on the appropriate treatment. In addition, simply internal rotating the arm during surgery when using the traditional posterior portal and $30^{\circ}$ arthroscope can be a valuable method.

The purpose of this study was to investigate the clinical effects of Korean medical treatments combined with Embedding acupuncture on patients with supraspinatus tendon partial tear. We reviewed the medical records of 1 patients with supraspinatus tendon partial tear at Pureunsan oriental medical clinic from Oct, 2017 to November, 2017. The patient received embedding acupuncture therapy and oriental medical therapy. To evaluate the efficacy of the treatments, the patient was asked to complete a Visual analogue scale(VAS) and the Shoulder pain and disability index during treatment period. The VAS of the patient decreased more than the screening period. The SPADI change of the embedding acupuncture group were greater than non treatment period. Embedding therapy combined with Korean medical treatment might be effective in reducing pain and improving the life quality of patients with supraspinatus tendon partial tear. We hope that further studies will be done to produce more clinical data and ensure effective application of these results.

This case was report of intra-articular bee venom pharmacopuncture injection on the patient with Acute Traumatic Partial tear of meniscus. We used intra-articular bee venom pharmacopuncture injection to Acute Traumatic Partial tear of meniscus diagnosed by symptoms and MR imaging. Be under treatment if necessary we prescribed herbal medication and physiotherapy. The state of patient was measured by Visual Analog Scale(VAS) and Walking time and Western Ontario and McMaster Universities(WOMAC) Index score. After several times of treatments, noticeable reduction of pain was measured and increased time of walking on floor and decreased WOMAC score. This results suggest that intra-articular bee venom pharmacopuncture injection are effective to treatments of Acute Traumatic Partial tear of meniscus.

Background: Atelocollagen has been studied for restoration of rotator cuff tendon. In this study, we attempted to evaluate the clinical outcome of ultrasound-guided atelocollagen injection in an outpatient clinic for patients with partial rotator cuff tear. Methods: We recruited 42 outpatients who visited our hospital from May 2019 to September 2019. Atelocollagen injection was performed in patients with partial rotator cuff tear diagnosed by magnetic resonance imaging and ultrasound. American Shoulder and Elbow Surgeons (ASES), Constant, Korean Shoulder Score (KSS) and Simple Shoulder Test (SST) scores, and range of motion were assessed before injection and after 2 months. Statistically, we analyzed the clinical results using the Wilcoxon signed-rank test. Results: Finally, 15 patients were enrolled for analysis. There was no significant difference between pre- and post-injection in terms of range of motion, ASES (57.0 vs. 60.4), Constant (56.4 vs. 58.9), KSS (64.6 vs. 68.5), and pain-visual analog scale (4.2 vs. 3.7), except function-visual analog scale (F-VAS; 6.3 vs. 7.1) and SST (6.6 vs. 6.9). A significant difference was found in SST (P=0.046) and F-VAS (P=0.009). According to the ultrasound results at 2 months, we found hyperechoic materials in three of seven patients. The most common complication of atelocollagen injection was post-injection pain (53%, 8/15). Conclusions: Ultrasound-guided atelocollagen injection for partial rotator cuff tear showed no significant change in terms of clinical outcomes, except for F-vas and SST score. Tendon regeneration was not clear due to the remnants of atelocollagen present at 2-month follow-up ultrasound. There seems to be alarming post-injection pain for 2 to 3 days in the patients who received atelocollagen injection in an outpatient clinic.
