Background:
Massive rotator cuff tears (MRCTs) can be challenging to treat, and the efficacy of repair of MRCTs in older patients has been debated.
Purpose:
To report minimum 5-year outcomes after ...primary arthroscopic rotator cuff repair of MRCT and determine whether age affects outcomes.
Study Design:
Case series; Level of evidence 4.
Methods:
The study included consecutive patients with MRCTs who were treated with arthroscopic rotator cuff repair by a single surgeon between February 2006 and October 2016. MRCTs were defined as ≥2 affected tendons with tendon retraction to the glenoid rim and/or a minimum exposed greater tuberosity of ≥67. Patient-reported outcome (PRO) data collected preoperatively and at a minimum of 5 years included the American Shoulder and Elbow Surgeons (ASES) score; Single Assessment Numeric Evaluation (SANE) score; the shortened version of the Disabilities of the Arm, Shoulder and Hand score (QuickDASH); the 12-Item Short Form Health Survey (SF-12) Physical Component Summary (PCS); and patient satisfaction. Surgical failure was defined as subsequent revision rotator cuff surgery or conversion to reverse total shoulder arthroplasty. Regression analysis was performed to determine whether age had an effect on clinical outcomes.
Results:
A total of 53 shoulders in 51 patients (mean age, 59.7 years; range, 39.6-73.8 years; 34 male, 19 female) met inclusion criteria with a mean follow-up of 8.1 years (range, 5.0-12.1 years). Three shoulders (5.7%) failed at 2.4, 6.0, and 7.1 years. Minimum 5-year follow-up was obtained in 45 of the remaining 50 shoulders (90%). Mean PROs improved as follows: ASES from 58.8 to 96.9 (P < .001), SANE from 60.5 to 88.5 (P < .001), QuickDASH from 34.2 to 6.8 (P < .001), and SF-12 PCS from 41.1 to 52.2 (P < .001). Patient satisfaction was a median of 10 (on a scale of 1-10). Age was not associated with any PRO measures postoperatively (P > .05).
Conclusion:
This study demonstrated significantly improved clinical scores, decreased pain, and increased return to activity for patients with MRCT at midterm follow-up (mean, 8.1 years; range, 5.0-12.1 years). In this patient cohort, no association was found between age and clinical outcomes.
Background:
The prevalence of partial-thickness rotator cuff tears (PTRCTs) has been reported to be 13% to 40% within the adult population, accounting for 70% of all rotator cuff tears. Approximately ...29% of PTRCTs will progress to full-thickness tears if left untreated. The long-term clinical course after arthroscopic repair of PTRCTs is not well known.
Purpose:
To investigate minimum 10-year patient-reported outcomes (PROs) after arthroscopic rotator cuff repair (RCR) of the supraspinatus tendon and to report reoperation and complication rates.
Study Design:
Case series; Level of evidence, 4.
Methods:
Patients were included who underwent arthroscopic RCR of a PTRCT performed by a single surgeon between October 2005 and October 2011. Arthroscopic RCR was performed with a transtendon repair of partial, articular-sided supraspinatus tendon avulsions, bursal-sided repair, or conversion into a full-thickness tear and repair. PRO data were collected preoperatively and at a minimum 10 years postoperatively. PRO measures included the American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation score, the shortened version of Disabilities of the Arm, Shoulder and Hand score (QuickDASH), the 12-Item Short Form Health Survey Physical Component Summary, and patient satisfaction. Subanalyses were performed to determine if tear location or age was associated with outcomes. Retears, revision surgery, and surgical complications were recorded.
Results:
In total, 33 patients (21 men, 12 women) at a mean age of 50 years (range, 23-68) met criteria for inclusion. Follow-up was obtained in 28 (87.5%) of the 32 eligible patients ≥10 years out from surgery (mean, 12 years; range, 10-15 years). Of the 33 PTCRTs, 21 were articular sided and 12 were bursal sided. Of the 33 patients, 26 underwent concomitant biceps tenodesis. At follow-up, the mean PROs were significantly improved when compared with preoperative levels: American Shoulder and Elbow Surgeons score from 67.3 to 93.7 (P < .001), Single Assessment Numeric Evaluation from 70.9 to 91.2 (P = .004), QuickDASH from 22.3 to 6.6 (P < .004), and 12-Item Short Form Health Survey Physical Component Summary from 44.8 to 54.2 (P < .001). Median postoperative satisfaction was 10 (range, 5-10). No patient underwent revision surgery.
Conclusion:
Arthroscopic repair of PTRCTs results in excellent clinical outcomes and high patient satisfaction at minimum 10-year follow-up. Furthermore, the procedure is highly durable, with a clinical survivorship rate of 100% at 10 years.
Loneliness is gaining attention globally as a public health issue because elevated loneliness increases one's risk for depression, compromised immunity, chronic illness, and mortality. Our objective ...is to zoom into how loneliness has historically evolved through midlife and investigate whether elevations in loneliness are confined to the United States or are similarly transpiring across peer European nations. We use harmonized data on loneliness from nationally representative longitudinal panel surveys from the United States and 13 European nations to directly quantify similarities and differences in historical change of midlife loneliness trajectories. Compared with any other European nation/region, overall levels of loneliness in the United States are consistently higher by a magnitude of 0.3-0.8
. Middle-aged adults in the United States, England, and Mediterranean Europe today report higher levels of loneliness than earlier born cohorts, whereas no historical changes (if not historically lower levels) were observed in Continental and Nordic Europe. Our discussion focuses on possible reasons for cross-national differences in midlife loneliness, including cultural factors, social and economic inequalities, and differences in social safety nets.

Although short-term results are promising, there are limited data for long-term results of arthroscopic subscapularis (SSC) repair. The purpose of this study is to report minimum 10-year outcomes of ...primary arthroscopic repair of isolated partial or full-thickness tears of the upper third of the SSC tendon.
Patients who underwent arthroscopic repair of isolated upper third SSC tears, Lafosse type I (>50% of tendon thickness) or type II were included. Surgeries were performed by a single surgeon between November 2005 and August 2011. Patient-reported outcome measures were prospectively collected and retrospectively reviewed at minimum follow-up of 10 years. Patient-reported outcomes utilized included the American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation score (SANE), Quick Disabilities of the Arm, Shoulder and Hand score (QuickDASH), the Short Form 12 physical component summary, return to activity, and patient satisfaction. A subanalysis of patient age and outcomes was performed. Retears, revision surgeries, and surgical complications were recorded.
In total, 29 patients with isolated upper third SSC repairs were identified. After application of exclusion criteria, 14 patients were included in the final analysis. Follow-up could be obtained from 11 patients. The mean age at surgery was 52.7 years (range: 36-72) and the mean follow-up was 12 years (range 10-15 years). The American Shoulder and Elbow Surgeons score improved from 52.9 ± 21.8 preoperatively to 92.2 ± 13.7 postoperatively (P < .001). Regarding the SANE and QuickDASH scores, only postoperative data were available. Mean postoperative SANE, QuickDASH, and Short Form 12 physical component summary scores were 90.27 ± 10.5, 14.6 ± 15.5, and 49.2 ± 6.6, respectively. Median patient satisfaction was 10 (range 6-10). Patients reported improvements in sleep, activities of daily living, and sports. There was no correlation between patient age and clinical outcome (P > .05). No patients underwent revision surgery for a SSC retear.
Arthroscopic repair of upper third SSC tendon tears leads to improved clinical scores and high patient satisfaction at minimum 10-year follow-up. The procedure is durable, with no failures in the presented cohort.
Reconstruction of unstable osteochondritis dissecans lesions of the capitellum using fresh osteochondral allograft transplantation from the capitellum has the advantages of restoring hyaline ...cartilage, matching the native radius of curvature, and avoiding the donor-site morbidity encountered with osteochondral autograft transfer. This technical note describes the indications and contraindications, pertinent anatomy, and surgical technique of open osteochondral allograft transplantation using fresh distal humerus allograft for the treatment of unstable osteochondritis dissecans lesions of the capitellum.
The critical shoulder angle (CSA) reflects the lateral extent of the acromion and the inclination of the glenoid. In 2013, CSA was first introduced and its association with rotator cuff (RC) tears ...and glenohumeral osteoarthritis (GHOA) was shown. It was speculated that with a high CSA, there was an increased superior force vector from the deltoid and that this superior force led to RC tears. Conversely, when the CSA was low, there was a greater compressive force from the deltoid and that this compressive force led to GHOA. CSA serves as a further development of 2 previously reported measurements (glenoid inclination and acromial index). A key potential therapeutic aspect of the CSA is the ability to modify it surgically, which theoretically could protect RC repairs or prevent progression. In our current clinical practice, we perform lateral acromioplasty (LA) in patients undergoing treatment of subacromial impingement with an "at-risk" rotator cuff (partial rotator cuff tear and severe tendinopathy on magnetic resonance imaging) with a CSA > 38° or all patients with a CSA >35° after an RC repair to protect the RC repair construct. The relationships of high and low CSA, the anatomic safe zone, and thus clinical applicability of LA are well established and performed in our daily surgical practice. However, we do not yet have widespread clear clinical evidence on potential benefits regarding the clinical outcome after LA. Finally, at this time, the downsides seem minimal, so we continue to use LA as an adjunct in patients with RC tears and RC tendons that are at risk.
Bacteriophages are an attractive tool for application in the therapy of bacterial infections, for biological control of bacterial contamination of foodstuffs in the alimentary industry, in plant ...protection, for control of water-borne pathogens, and control of environmental microflora. This review is mainly focused on structures governing phage recognition of host cell and mechanisms of phage adsorption and penetration into microbial cell.
In the management of multidirectional type of shoulder instability (MDI), arthroscopic surgical stabilization is a preferred treatment option after failed conservative therapy regimens because of the ...ability to easily access all aspects of the capsule with one surgical procedure. As arthroscopic techniques have evolved, factors critical to postoperative success have been elucidated. Currently, optimal arthroscopic treatment of MDI involves circumferentially restoring labral integrity, a tailored, patient-specific surgical reduction of capsular volume, and adequately managing potential lesions of the biceps anchor. The purpose of this article and accompanying video is to present our technique for arthroscopic circumferential labral repair and pancapsular shift using knotless all-suture anchors in the setting of MDI with a concurrent type II SLAP lesion.

Video depicting the surgical technique for arthroscopic circumferential labral repair and pancapsular shift using knotless all-suture anchors in the setting of multidirectional instability of a patient’s right shoulder. The repair of a concurrent type II SLAP lesion also is demonstrated. The surgery is performed with the patient in a beach chair position. The diagnostic arthroscopy and anterior labral repair are viewed from a standard posterior viewing portal, and the posterior labral repair is viewed from an anterosuperior portal.
Fisetin has been shown to be beneficial for brain injury and age-related brain disease via different mechanisms. The purpose of this study was to determine the presence of senescent cells and the ...effects of fisetin on cellular senescence in the brain and other vital organs in old sheep, a more translational model. Female sheep 6–7 years old (N = 6) were treated with 100 mg/kg fisetin or vehicle alone on two consecutive days a week for 8 weeks. All vital organs were harvested at the time of sacrifice. Histology, immunofluorescence staining, and RT-Q-PCR were performed on different regions of brain tissues and other organs. Our results indicated that fisetin treatment at the current regimen did not affect the general morphology of the brain. The presence of senescent cells in both the cerebral brain cortex and cerebellum and non-Cornu Ammonis (CA) area of the hippocampus was detected by senescent-associated β-galactosidase (SA-β-Gal) staining and GL13 (lipofuscin) staining. The senescent cells detected were mainly neurons in both gray and white matter of either the cerebral brain cortex, cerebellum, or non-CA area of the hippocampus. Very few senescent cells were detected in the neurons of the CA1-4 area of the hippocampus, as revealed by GL13 staining and GLB1 colocalization with NEUN. Fisetin treatment significantly decreased the number of SA-β-Gal+ cells in brain cortex white matter and GL13+ cells in the non-CA area of the hippocampus, and showed a decreasing trend of SA-β-Gal+ cells in the gray matter of both the cerebral brain cortex and cerebellum. Furthermore, fisetin treatment significantly decreased P16+ and GLB1+ cells in neuronal nuclear protein (NEUN)+ neurons, glial fibrillary acidic protein (GFAP)+ astrocytes, and ionized calcium binding adaptor molecule 1 (IBA1)+ microglia cells in both gray and white matter of cerebral brain cortex. Fisetin treatment significantly decreased GLB1+ cells in microglia cells, astrocytes, and NEUN+ neurons in the non-CA area of the hippocampus. Fisetin treatment significantly decreased plasma S100B. At the mRNA level, fisetin significantly downregulated GLB1 in the liver, showed a decreasing trend in GLB1 in the lung, heart, and spleen tissues, and significantly decreased P21 expression in the liver and lung. Fisetin treatment significantly decreased TREM2 in the lung tissues and showed a trend of downregulation in the liver, spleen, and heart. A significant decrease in NRLP3 in the liver was observed after fisetin treatment. Finally, fisetin treatment significantly downregulated SOD1 in the liver and spleen while upregulating CAT in the spleen. In conclusion, we found that senescent cells were widely present in the cerebral brain cortex and cerebellum and non-CA area of the hippocampus of old sheep. Fisetin treatment significantly decreased senescent neurons, astrocytes, and microglia in both gray and white matter of the cerebral brain cortex and non-CA area of the hippocampus. In addition, fisetin treatment decreased senescent gene expressions and inflammasomes in other organs, such as the lung and the liver. Fisetin treatment represents a promising therapeutic strategy for age-related diseases.
Neurovascular anatomy has not been previously quantified for the arthroscopic snapping scapula approach with the patient in the most frequent patient position (“chicken-wing” position). The purposes ...of this study were (1) to determine anatomic relationships of the superomedial scapula and neurovascular structures at risk during arthroscopic surgical treatment of snapping scapula syndrome (SSS), (2) to compare these measurements between the arm in the neutral position and the arm in the chicken-wing position, and (3) to establish safe zones for arthroscopic treatment of SSS.
Eight fresh-frozen cadaveric hemi-torsos (mean age, 55.8 years; range, 52-66 years) were dissected to ascertain relevant anatomic structure locations including the (1) spinal accessory nerve, (2) dorsal scapular nerve, and (3) suprascapular nerve. A coordinate measuring device was used to collect data on the relationships of anatomic landmarks and at-risk structures during the surgical approach.
The dorsal scapular nerve was a mean of 24.4 mm medial to the superomedial scapula in the neutral position and 33.1 mm medial in the chicken-wing position (P < .001); the dorsal scapular nerve was 21.7 mm medial to the medial border of the scapular spine in the neutral position and 35.5 mm medial in the chicken-wing position (P < .001). The mean distance from the superomedial angle to the spinal accessory nerve intersection at the superior scapular border was 16.5 mm in the neutral position and 15.0 mm in the chicken-wing position (P = .031). The average distance from the superomedial angle to the closest point of the spinal accessory nerve was 11.6 mm and 10.4 mm in the neutral position and chicken-wing position, respectively (P = .039).
Neurologic structures around the scapula vary significantly between the neutral arm position and the chicken-wing position commonly used in the arthroscopic treatment of SSS. The chicken-wing position improves safe distances for the dorsal scapular nerve during medial-portal placement and should be considered as a primary position for arthroscopic management of SSS.
