Role of Critical Shoulder Angle in Degenerative Type Rotator Cuff Tears: A Turkish Cohort Study.

BACKGROUND This retrospective study investigated the association between the critical shoulder angle (CSA) and the development of full-thickness rotator cuff tears (FTRCTs) in the Turkish population. The CSA is an imaging parameter that quantifies the relationship between the inclination of the glenoid and the lateral extension of the acromion in the coronal plane. The CSA is an anatomical measurement, and higher CSA values have been associated with an increased incidence of FTRCTs. However, there is a lack of data on CSA regarding the Turkish population. MATERIAL AND METHODS In this study, CSA measurements were recorded in 2 groups: 50 patients with FTRCT who had arthroscopic repair (group 1) and 50 age- and sex-matched individuals with no FTRCT detected by magnetic resonance imaging (group 2). Sex, age, affected side, dominant side, and smoking status were recorded for each patient. The CSA measurements of the affected sides were performed on true anterior-posterior view radiographs. RESULTS The results showed a statistically significant difference between the mean CSA values of group 1 (37.48°) and group 2 (33.53°), P<0.001. CSA values of 36 and above had a sensitivity of 73.58%, specificity of 74.47%, positive predictive value of 75%, and negative predictive value of 74.47% for detecting FTRCT. CONCLUSIONS CSA measurement on radiographs is a useful diagnostic tool in the Turkish population, and an above-average CSA value is associated with a significantly increased incidence of degenerative-type FTRCT.

Tetralogy of Fallot with double aortic arch and aortopulmonary window: a very rare trifecta.

Tetralogy of Fallot with an aortopulmonary window and double aortic arch is very rare. This complex coexistence may be over a wide clinical spectrum. Herein, we present an asymptomatic 8-day-old infant who was diagnosed as having tetralogy of Fallot, double aortic arch, and an aortopulmonary window using transthoracic echocardiography while being examined for microcephaly.

Incidental detection of accessory mitral valve in adolescent with atrial septal defect: Diagnosis with 3D transesophageal echocardiography and excision with transaortic method.

BACKGROUND: Accessory mitral valve tissue (AMVT) is an extremely rare causes left ventricular outflow tract (LVOT) obstruction and is usually incidentally detected in childhood. It is often associated with other cardiac and vascular congenital malformations. CASE PRESENTATION: In this case, we present a 15-year-old girl was diagnosed with AMVT by transesophageal echocardiography, resulting in LVOT obstruction during systole. Interestingly enough, the patient's accessory mitral valve remained undetected for years until he became symptomatic for wide ASD. Successful closure of the ASD with resection of the AMVT was performed with a transaortic approach. The patient was hemodynamically stable postoperatively. There were no abnormalities in the mitral valves and LVOT. CONCLUSION: It was also unusual to see AMVT with ASD instead of other frequently associated other congenital anomalies. Accessory mitral valve should be considered a rare but important cause of left ventricular outflow tract obstruction in childhood.

The impact of COVID-19 pandemic in the first 100 days on orthopedic trauma surgery practice, the experience of a university hospital in Istanbul.

BACKGROUND: With the rapid and effective change created by the COVID-19 pandemic in all medical practice, we aimed to evaluate the impact of the first 100 days of the COVID-19 pandemic on the operations performed in a reference university hospital in the field of orthopedics and traumatology. Compare the results with the same period of the previous year and aim to evaluate importance of restrictions. METHODS: The operations performed in orthopedics and traumatology clinic between March 18, 2020 (the day we stopped the elective surgeries), and July 1, 2020 (when the normalization process began), were collected from the electronic archive to compare with the same period of 2019. RESULTS: Comparing the same periods of the year, it was seen that 102 surgeries were performed in the 2020 COVID-19 period compared to 380 operations performed in 2019. Although most of the operations performed during the COVID-19 period were traumas, the comparison revealed that trauma cases decreased by 25% from 73 to 58 (p<0.001). Among trauma patients operated in the restraint period, decrease in the pediatric group and the increase in patients over 65 years of age had seen statistically significant. Compared to the same period of the previous year, 50% increase seen in amputation cases related to diabetic foot (p<0.001). CONCLUSION: The postponement of elective cases due to the COVID-19 pandemic enabled us to manage trauma cases despite decreasing capacity utilization. In addition, it was observed that the transition of schools to online education and the implementation of curfews significantly reduced the number of trauma in the pediatric group. Separation of operating rooms and wards had a huge effect on protection of non-COVID patients. We hope that, in light of this study, we can guide health policies and help other colleagues to manage the possible new waves of the pandemic process or similar processes that may occur in the future.

Maternal Stress and Neonatal Nutrition during the COVID-19 Era.

Objective: COVID-19 pandemic has put a tremendous amount of stress on people, which can negatively affect nursing. Previous studies showed that perceived stress and cortisol levels in the postpartum period correlate with the LATCH scores, which is a simple tool to assess the pattern of nursing. Likewise, greater prenatal anxiety was associated with a shorter breastfeeding duration. We aimed to evaluate whether pregnant women were under extra stress due to the COVID-19 pandemic and if this stress affected their breastfeeding patterns and anthropometric measures of the neonates. Methods: Pregnant women giving birth to healthy neonates were included. Coronavirus Anxiety Scale (CAS) and Beck Anxiety Inventory (BAI) were used to assess the anxiety levels of the mothers, and LATCH breastfeeding assessment tool was used to assess the nursing. The results of these scales and anthropometric measures of the neonates were recorded. Results: Only one mother showed coronavirus-specific anxiety. Therefore, further analysis was done based on the Beck Anxiety (BA) levels of the mothers. CAS and BA scores were positively correlated (p<0.001, r=0.444), indicating that coronavirus-specific anxiety increased with increasing general anxiety. None of the variables changed depending on the anxiety levels of the mothers, except for the % weight gain at day five (p=0.020, r=-0.248). Even though anxiety seemed to show a small effect on weight loss during the first neonatal days, percent weight gain results did not seem to correlate with the anxiety levels in later stages (first month of life). Furthermore, LATCH scores of the infants on day one were positively correlated with BA scores of the mothers (p=0.045, r=0.175). Conclusion: COVID-19 seemed to have no additional effect on the stress levels of the mothers. The more the mothers have anxiety, the more they may stress about the well-being of their infants, which can improve their nursing pattern.

Current concepts in anterior glenohumeral instability: diagnosis and treatment.

The glenohumeral joint is the most dislocated articulation, accounting for more than 50% of all joint dislocations. The reason behind shoulder instability should be investigated in detail for successful management, and the treatment plan should be individualized for all patients. Several classification systems have been proposed for glenohumeral instability. A physical exam is mandatory no matter what classification system is used. When treating patients with anterior shoulder instability, surgeons need to be aware of the critical size of the bone loss, which is commonly seen. The glenoid track concept was clinically adopted, and the measurement of the glenoid track for surgical decision-making is recommended. Detailed assessment of existing soft tissue injury to the labrum, capsule, glenohumeral ligaments, and rotator cuff is also mandatory as their presence influences the surgical outcome. Rehabilitation, arthroscopic repair techniques, open Bankart procedure, capsular plication, remplissage, Latarjet technique, iliac crest, and other bone grafts offer the surgeon different treatment options according to the type of patient and the lesions to be treated. Three-dimensional (3D) technologies can help to evaluate glenoid and humeral defects. Patient-specific guides are low-cost surgical instruments and can be used in shoulder instability surgery. 3D printing will undoubtedly become an essential tool to achieve the best results in glenohumeral instability surgery.

Gene expression profiling of primary fibrochondrocyte cultures in traumatic and degenerative meniscus lesions.

PURPOSE: This study aimed to investigate how fibroblastic and chondrocytic properties of human meniscal fibrochondrocytes are affected in culture conditions according to the type of meniscal pathology and localization, and to provide basic information for tissue-engineering studies. METHODS: Primary fibrochondrocyte cultures were prepared from meniscus samples of patients who had either traumatic tear or degeneration due to osteoarthritis. Cultures were compared in terms of mRNA expression levels of COL1A1, COL2A1, COMP1, HIF1A, HIF2A, and SOX9 and secreted total collagen and sulfated sGAG levels according to the type of meniscal pathology, anatomical localization, and the number of subcultures. RESULTS: mRNA expression levels of COL1A1, COMP1, HIF1A, HIF2A, and SOX9 were found to be increased in subsequent subcultures in all specimens. COL1A1 mRNA expression levels of both lateral and medial menisci of patients with traumatic tear were significantly higher than in patients with degenerative pathology, indicating a more fibroblastic character. P1 subculture of lateral and P3 or further subculture of medial meniscus showed more fibroblastic characteristics in patients with degenerative pathology. Furthermore, in patients with degenerative pathology, the subcultures of the lateral meniscus (especially on the inner part) presented more chondrocytic characteristics than did those of medial meniscus. CONCLUSIONS: The mRNA expression levels of the cultures showed significant differences according to the anatomical localization and pathology of the meniscus, indicating distinct chondrocytic and fibroblastic features. This fundamental knowledge would help researchers to choose more efficient cell sources for cell-seeding of a meniscus scaffold, and to generate a construct resembling the original meniscus tissue.

Management of congenital cardiac surgery during COVID-19 pandemic.

The new coronavirus infection, which was first seen in China in late December, 2019 and eventually became a worldwide pandemic, poses a serious threat to public health. After a high spike in the number of new COVID-19 infection cases following the increase in overall daily death toll in Turkey, Turkish Ministry of Health has taken immediate precautions to postpone elective surgeries in order to reduce the burden to the healthcare system which might be challenged. Whereas different areas of medicine were able to suspend their operative procedures during this period, this was not completely possible in paediatric cardiovascular surgery due to the severity and urgency of congenital heart disease patients requiring operation. Based on the guideline that was published by the Turkish Paediatric Cardiology and Cardiac Surgery Association, in which the patients requiring surgical intervention during the COVID-19 pandemic period are ranked according to the priority, directions were given regarding the operations that hereby, be delayed, we report our experience in 29 cases retrospectively, regarding the pre-operative evaluation of these patients, makings of an emergency operation decision, and strategies taken about intra-operative and post-operative management and arrangements during the pandemic period. In this article, we present crucial precautions that were applied in paediatric cardiovascular surgery and extensive list of cases in order to deliver highest level of the patient safety and protection for the surgical team.

Pectoralis major tendon transfer for subscapularis deficiency following multiple failed instability surgeries: A case report.

Here, we report a case of a 30-year-old man with a diagnosis of complex shoulder instability, who was treated successfully by pectoralis major transfer following a series of failed instability correction surgeries. The patient was admitted to our outpatient clinic with an approximately 6-year history of chronic shoulder instability following several failed operations, including open Bankart repair, open capsular plication and Bankart repair, open capsule repair, arthroscopic Bankart repair, and Bristow-¬Latarjet procedure. Physical examination revealed persistent shoulder pain, weakness, and a limited range of motion. Imaging studies demonstrated complete subscapularis muscle atrophy with Goutallier grade 4 fatty infiltration. The decision for revision surgery was made owing to his shoulder findings and clinical symptoms. The intra-operative assessment revealed the subscapularis muscle to be fully atrophic and irreparable. The pectoralis major muscle was transferred from the intertubercular groove of the humerus to the lesser tuberosity. Postoperatively, the patient had 4 weeks of shoulder immobilization. Physical examination demonstrated an improved shoulder range of motion without evidence of recurrent shoulder instability. The authors encountered no sign of dislocation for 2.5 years of follow-up after the surgery. In conclusion, subscapularis muscle atrophy or insufficiency should be considered in the differential diagnosis of patients with failed shoulder instability surgeries. Pectoralis major tendon transfer may be successfully performed for the surgical treatment of such patients.

Treatment options for locked posterior shoulder dislocations and clinical outcomes.

Posterior dislocations are rare and diagnostically difficult injuries. Diagnosis is often delayed and this leads to a locked posteriorly dislocated humeral head.Treatment options include conservative methods and surgical anatomic reconstruction options as well as non-anatomic surgical procedures such as subscapularis tendon transfer, hemiarthroplasty and total shoulder arthroplasty.Decision-making for treatment as well as prognosis depend on the extent of the articular defect size of the humeral head, duration of the dislocation and patient-specific conditions such as age and activity levels.

Can capsular plication compensate the lack of one suture anchor in an arthroscopic three suture anchor Bankart repair? A comparative study.

OBJECTIVE: The aim of this study was to compare the complication rates and clinical results of labral repair with two suture anchors and capsular plication, and labral repair with three suture anchor fixation in artroscopic Bankart surgery. METHODS: Sixty-nine patients (60 males, 9 females; mean age: 28.2 ± 7.8 years (range: 16-50)) who had undergone arthroscopic repair of a labral Bankart lesion were evaluated. Group A underwent an arthroscopic Bankart repair with three knotless suture anchors, while group B underwent a modified arthroscopic Bankart repair with two knotless suture anchors and an additional capsular plication procedure. The mean follow-up was 52.5 months. Constant Shoulder Score (CSS), Rowe Score (RS), modified UCLA Shoulder Score (mUSS) and range of motion (ROM) were used as outcome measures. RESULTS: In both groups, a significant improvement was detected in functional outcomes at postoperative last follow-up compared to the preoperative period. No statistically significant difference was found (p > 0.05) in clinical scores (CSS; Group A: 89.7, Group B: 80.2) (RS; Group A: 88.2, Group B: 80.2) (mUSS; Group A: 26.3, Group B: 25.7) external rotation loss (At neutral; Group A: 4.5°, Group B: 5.2°. At abduction; Group A: 4.3°, Group B: 5.7°) and recurrence rates (Group A: 13.3%, Group B: 20.8%). Although the difference was not statistically significant, the recurrence rate was higher in group B (20.8%), compared to group A (13.3%), despite the shorter average follow-up time of group B (p = 0.417). CONCLUSIONS: Arthroscopic repair of labral Bankart lesions with both techniques showed good functional outcomes and stability at the latest follow-up. Higher recurrence rate despite the shorter average follow-up of group B suggests that two anchor usage might not be sufficient for Bankart repair in terms of better stability and less recurrence risk. LEVEL OF EVIDENCE: Level III, Therapeutic Study.

Arthroscopic double-row rotator cuff repair: a comprehensive review of the literature.

Rotator cuff repairs seek to achieve adequate tendon fixation and to secure the fixation during the process of biological healing. Currently, arthroscopic rotator cuff repair has become the gold standard. One of the earliest defined techniques is single-row repair but the inadequacy of single-row repair to precisely restore the anatomical footprint as well as the significant rates of retear especially in large tears have led surgeons to seek other techniques. Double-row repair techniques, which have been developed in response to these concerns, have various modifications like the number and placement of anchors and suture configurations. When the literature is reviewed, it is possible to say that double-row repairs demonstrate superior biomechanical properties. In regard to retear rates, both double row and transosseous equivalent (TOE) techniques have also yielded more favorable outcomes compared to single-row repair. But the clinical results are conflicting and more studies have to be conducted. However, it is more probable that superior structural integrity will yield better structural and functional results in the long run. TOE repair technique is regarded as promising in terms of better biomechanics and healing since it provides better footprint contact. Knotless TOE structures are believed to reduce impingement on the medial side of tendons and thus aid in tendon nutrition; however, there are not enough studies about its effectiveness. It is important to optimize the costs without endangering the treatment of the patients. We believe that the arthroscopic TOE repair technique will yield superior results in regard to both repair integrity and functionality, especially with tears larger than 3 cm. Although defining the pattern of the tear is one of the most important guiding steps when selecting the repair technique, the surgeon should not forget to evaluate every patient individually for tendon healing capacity and functional expectations.

Acromioclavicular joint injuries: diagnosis, classification and ligamentoplasty procedures.

Acromioclavicular (AC) joint injury is a frequent diagnosis after an acute shoulder trauma - often found among athletes and people involved in contact sports.This injury occurs five times more frequently in men than in women, with the highest incidence in the 20- to 30-year-old age group. Patients usually complain of pain and tenderness over the shoulder, particularly over the AC joint.Depending on the degree of injury, the clavicle may become prominent on the injured site.The original classification was described by Rockwood and Green according to the injured ligament complex and degree and direction of clavicular displacement.Many surgical procedures have been described; among these are screws, plates, muscle transfer, ligamentoplasty procedures and ligament reconstruction using either autograft or allografts.With the advancement of shoulder arthroscopy, surgeons are much more capable of performing mini-open or arthroscopically-assisted procedures, allowing patients an earlier return to their daily living activities. However, the results of conventional open techniques are still comparable.The introduction of new arthroscopic equipment provides a great variety of surgical procedures, though every new technique has its own advantages and pitfalls. Currently there is no gold standard for the surgical treatment of any type of AC injury, though it should be remembered that whenever an arthroscopic technique is chosen, the surgeon's expertise is likely to be the most significant factor affecting outcome.

The comparison of arthroscopic acromioplasty with and without acromioclavicular coplaning.

BACKGROUND: Coplaning means the removal of medial acromial spurs and inferior aspect of the distal clavicle. The aim of the study was to evaluate the outcomes of arthroscopic acromioplasty with and without coplaning in patients without acromioclavicular (AC) joint arthritis. METHODS: Because of impingement syndrome, arthroscopic subacromial decompression and acromioplasty was performed in Group 1 (9 males/31 female). In addition, coplaning was performed in Group 2 (8 males/21 females) by two different surgeons. The mean age was 48 in Group 1, 46 in Group 2. The mean follow-up was 50 months and 44 months, respectively. RESULTS: Constant score, cross-body adduction test and AC joint tenderness was used for follow-up. The mean preoperative Constant scores were 45 points (range: 34-76 points) in Group 1, 39 points (range: 32-69 points) in Group 2. The mean Constant scores at the latest follow-up was 78 points (range: 68-100 points) for Group 1, 84 points (range: 72-100 points) for Group 2. There was no statistically difference between two groups at the latest follow-up (p<0.05). In two patients in Group 2, cross-body adduction test was positive but asymptomatic. CONCLUSION: Excision of the inferior side of the lateral clavicle to the level of the acromion with minimal disruption of the joint capsule does not develop AC joint symptoms in long-term follow-up.

Current Surgical Treatment Options of Rheumatoid Shoulder.

BACKGROUND: Rheumatoid Arthritis (RA) is an inflammatory disease with destructive pattern. Patients are suffering from pain and decreased functional outcome as the disease progress. Certain joints are widely discussed in the literature as well as shoulder girdle, but shoulder girdle surgical treatment options' indications and superiorities to each other were not compared entirely. MATERIALS AND METHODS: Treatment options, such as; synovectomy and bursectomy, resection interposition arthroplasty, hemiarthroplasty, humeral resurfacing arthroplasty, anatomical total shoulder arthroplasty and reverse shoulder arthroplasty, are examined for their timing, advantages, disadvantages and comparison. RESULTS: Patients' age is the main factor about the decision making in rheumatoid arthritis. Young aged patients demand high activity level, but as a result loosening of the implant is frequently encountered. Thus, the protection of the bone stock as much as possible must be the priority. For a young patient with disabling pain should be evaluated for less invasive surgeries such as; synovectomy and bursectomy, resection interposition arthroplasty and also for hemiarthroplasty for preservation of glenoid bone stock. But rotator cuff status, glenoid bone stock evaluation and grading of the glenoid defect become more important in old aged patients and the correct decision making can only be made by combining these factors. CONCLUSIONS: Age, functional demand, rotator cuff status and adequacy of glenoid bone stock are defined as major criteria for an optimal treatment. Even though RA patients require additional care for a good functional outcome; with correct decision-making, high quality of life is achievable.

High-grade bursal-side partial rotator cuff tears: comparison of mid- and long-term results following arthroscopic repair after conversion to a full-thickness tear.

BACKGROUND: Partial-thickness rotator cuff tears (PTRCTs) are one of the leading causes of shoulder dysfunction. Successful results have been reported with different treatment techniques, but the long-term consequences of these procedures are not yet clearly known. The purposes of this study were to evaluate and compare the mid- and long-term clinical outcomes of arthroscopically repaired bursal-side PTRCTs after conversion to full-thickness tears and identify the possible effects of age, gender, and hand dominance on clinical outcomes. METHODS: Twenty-nine patients who had undergone arthroscopic repair of a significant bursal-side PTRCT were functionally evaluated. The repair was made after conversion to a full-thickness tear. The average patient age was 55.2 years (range 35-69 years, SD ±7.6 years). Clinical outcomes were evaluated at 2 and 5 years after surgery. Constant Shoulder Score (CSS) and Visual Analogue Scale for Pain (VAS pain) were used as outcome measures. RESULTS: The average CSS improved from 38.9 preoperatively to 89.2 and 87.8 at 2 and 5 years after surgery, respectively (p < 0.001). The average VAS pain score decreased from 7.90 preoperatively to 1.17 and 1.31 at 2 and 5 years after surgery, respectively (p < 0.001). A significant improvement was detected in patient functional outcomes and VAS pain scores at 2 and 5 years after surgery compared with the preoperative period. The patients who underwent surgery from their non-dominant extremity showed a significantly higher CSS increase relative to those who underwent surgery on the dominant extremity (p = 0.022). CONCLUSIONS: Arthroscopic repair of high-grade bursal-side PTRCTs after conversion to full-thickness tears is a reliable surgical technique with good functional outcomes and pain relief both at mid- and long-term follow-ups. Surgery on the non-dominant side may be related to better functional outcomes.

Concomitant SLAP repair does not influence the surgical outcome for arthroscopic Bankart repair of traumatic shoulder dislocations.

BACKGROUND: Prior studies revealed the presence of superior labrum anterior-to-posterior (SLAP) injury together with Bankart lesions in some patients. The purpose of the study is to compare the clinical results of isolated Bankart repairs with the clinical results of Bankart repairs when performed with concomitant SLAP repairs. METHODS: The patients who underwent arthroscopic surgery for treatment of anterior glenohumeral instability were evaluated retrospectively. Group 1 consisted of 19 patients who had arthroscopic SLAP repair together with Bankart repair. The mean age of the patients was 23. Group 2 consisted of 38 patients who underwent isolated Bankart repair. The mean age was 24. Knotless anchors were used in both groups. RESULTS: The mean follow-up was 34 months (range: 26-72). In group 1, the mean preoperative Constant score was 84 (range: 74-90, standard deviation (SD): 5.91) and Rowe score was 64.1 (range: 40-70, SD: 8.14). In group 2, the preoperative Constant score was 84.4 (range: 70-96, SD: 5.88) and Rowe score was 60 (range: 45-70, SD: 7.95). In group 1, the postoperative mean Constant score raised to 96.8 (range: 88-100, SD: 2.91) and the mean Rowe score raised to 92.3 (range: 85-100, SD: 5.17). In group 2, the postoperative mean Constant score was 94.9 (range: 88-100, SD: 3.70) and the mean Rowe score was 94.2 (range: 80-100, SD: 4.71). The difference between the scores of two groups was insignificant ( p > 0.05). When the numbers of redislocations and range of motion were compared, no significant difference was found ( p > 0.05). CONCLUSION: Accompanying SLAP repair in surgical treatment with Bankart repair for shoulder instability does not affect the results negatively. Properly repaired labral tears extending from anterior inferior to the posterior superior of the glenoid in instability treatment have the same outcome in overall results as repaired isolated Bankart lesions.

Relations between mood characteristics, circadian preferences, and functionality in multiple sclerosis.

OBJECTIVE: Multiple sclerosis (MS) is a progressive disorder that results in demyelinization of the nerve fibers of the central nervous system. We aimed to determine chronobiological and mood features in patients with MS. METHODS: The sample comprised 75 patients with MS (54 women and 21 men) and 50 healthy individuals (38 women and 12 men). Sixty-three patients were relapsing-remitting MS and twelve patients had secondary progressive-type MS. Mood characteristics were assessed using subscales of the Profile of Mood States (POMS). Chronotypical characteristics were determined by the Morningness-Eveningness Questionnaire (MEQ). Univariate and structural equation modeling was applied to untangle the possible connections between variables. RESULTS: Both relapsing-remitting and secondary progressive patients scored higher on the depression-dejection and fatigue-inertia scales of the POMS than healthy individuals. Circadian preferences did not differ significantly between these groups. Patients using glatiramer acetate and other types of drugs had greater severity of functional impairment measured relative to interferon-beta treatment group. Glatiramer acetate had more negative effects on mood than interferon-beta therapy. This finding may be the result of significantly higher duration of disease and higher symptom severity scores in glatiramer acetate group. CONCLUSIONS: In the structural equation model, gender was found to be predictive for characteristics of mood.

Effect of both preoperative andpostoperative cryoceutical treatment on hemostasis and postoperative pain following total knee arthroplasty.

AIM: We aimed to evaluate the hemostatic effects and the clinical outcomes of preoperative and postoperative cryoceutical treatment (C-tx) following total knee arthroplasty. PATIENTS AND METHOD: 42 patients received C-tx both preoperatively, and postoperatively. In the control group, 45 patients did not receive any C-tx. Amount of bloody drainage and verbal rating pain scores were noted. RESULTS: We found significant difference in both the preoperative and postoperative hemoglobin levels and blood drainage (P<0.001). However, there was no significant difference in the average verbally rated pain scores (P>0.05). CONCLUSION: C-tx performed preoperatively and postoperatively for total knee arthroplasty is effective in decreasing perioperative and postoperative hemorrhage. However, it had no superior effect on the control of postoperative pain.

Superior labrum anterior to posterior lesions of the shoulder: Diagnosis and arthroscopic management.

After the improvement in arthroscopic shoulder surgery, superior labrum anterior to posterior (SLAP) tears are increasingly recognized and treated in persons with excessive overhead activities like throwers. Several potential mechanisms for the pathophysiology of superior labral tears have been proposed. The diagnosis of this condition can be possible by history, physical examination and magnetic resonance imaging combination. The treatment of type 1 SLAP tears in many cases especially in older patients is non-operative but some cases need arthroscopic intervention. The arthroscopic management of type 2 lesions in older patients can be biceps tenodesis, but young and active patients like throwers will need an arthroscopic repair. The results of arthroscopic repair in older patients are not encouraging. The purpose of this study is to perform an overview of the diagnosis of the SLAP tears and to help decision making for the surgical management.
