BACKGROUND: Numerous studies have identified factors that may affect the chances of rotator cuff healing after surgery. Intraoperative tendon quality may be used to predict healing and to determine type of repair and/or consideration of augmentation. There are no data that correlate how gross tendon morphology and degree of tendinopathy affect patient outcome or postoperative tendon healing. Purpose/Hypothesis: The purposes of this study were to (1) compare the gross appearance of the tendon edge during arthroscopic rotator cuff repair with its histological degree of tendinopathy and (2) determine if gross appearance correlated with postoperative repair integrity...

BACKGROUND: The deltoid ligament (DL) is the principal ligamentous stabilizer of the medial ankle joint. Little is known, however, about the contribution of the DL toward stabilizing the syndesmosis. The aim of this study was to arthroscopically evaluate whether the DL contributes to syndesmotic stability in the coronal plane. METHODS: Eight above-knee cadaveric specimens were used in this study. A lateral hook test was performed by applying 100 N of lateral force to the fibula in the intact state and after sequential transection of the DL, anterior-inferior tibiofibular ligament (AITFL), interosseous ligament (IOL), and posterior-inferior tibiofibular ligament (PITFL)...

REVIEW
C Gerhardt, L J Lehmann
In recent years, the understanding of shoulder fractures has changed due to the progress of arthroscopy. In addition to the cosmetic result, the access morbidity, particularly the integrity of the subscapularis muscle in glenoid and scapular fractures, must be mentioned as an advantage of a minimally invasive approach. Furthermore, necessary secondary interventions, e. g. hook plate removal, can be prevented or minimized by modern implants and arthroscopic techniques.However, the available data and publications are almost exclusively limited to technical notes or small case series, so statements about faster recreation or potential reduction of infection risk cannot be made...

Background: Arthroscopic stabilization is the most broadly used surgical procedure in the United States for management of recurrent shoulder instability. Latarjet coracoid transfer has been considered a salvage surgical procedure for failed arthroscopic repairs or cases of significant glenoid bone loss; however, with recent literature suggesting reduced risk of recurrent instability with Latarjet, several surgeons have advocated its broader utilization as a primary operation for treatment of shoulder instability...

Background: Workers' compensation status is associated with poor outcomes after rotator cuff repair surgery. The purpose of this study was to analyze a database of geriatric workers' compensation patients after surgical repair of the rotator cuff and identify both medical and nonmedical patient factors that influence the time it takes for them to return to work at full duty, including a comparison of arthroscopic and open techniques. Methods: An all workers' compensation database was queried for rotator cuff claims that were surgically managed using arthroscopic, open, or both approaches from 2003 to 2013 in patients aged ≥60...

The orthopedic field has experienced several major practice-changing pivotal shifts in the past several decades, such as the invention and application of the arthroscope or the implementation and advancement of joint arthroplasties. Most of these previous breakthroughs have focused on surgical techniques and devices. However, the next major advance in the field is likely to be related to biologic treatments. Although still in its early stage of development, orthopedic regenerative medicine, including cellular therapies, represents a great opportunity, since we are only beginning to understand their biological potential...

BACKGROUND: Anterior cruciate ligament tears are an unfortunate, but common, event in the United States, with an estimated 100-300,000 reconstructions performed annually. Limited literature has been published analyzing the reimbursement patterns for the reconstruction of this ligament and, thus, cost-effectiveness studies have relied mainly on data from a limited number of subjects and hospitals. PURPOSE: The purpose of this study was to perform an epidemiological cost analysis of anterior cruciate ligament reconstructions and to analyze and describe the reimbursement patterns for this procedure that can be used as reference for future cost-analysis studies...

A direct force on the superior aspect of the shoulder may cause acromioclavicular (AC) dislocation or separation. Severe dislocations can lead to chronic impairment, especially in the athlete and high-demand manual laborer. The dislocation is classified according to Rockwood. Types I and II are treated nonoperatively, while types IV, V and VI are generally treated operatively. Controversy exists regarding the optimal treatment of type III dislocations in the high-demand patient. Recent evidence suggests that these should be treated nonoperatively initially...

U-J Gerlach
Joint infections represent a severe complication that results in irreversible joint destruction when left untreated or treated inadequately. The reasons for joint infections include endogenous hematological and exogenous factors. In the patient cohort described here, the empyema was almost exclusively acquired through iatrogenic measures (e.g. arthroscopic operations, punctures and intra-articular infections) or as a result of fractures close to the joint and penetrating injuries. Acute joint empyema is an orthopedic emergency, which must be immediately surgically treated because irreversible cartilage damage can rapidly occur due to the pathophysiological process...
