Rotator cuff tendon injuries often occur at the tendon-to-bone interface (i.e., enthesis) area with a high prevalence for the elderly population. In addition, regeneration of the gradient structure of the enthesis is still a significant clinical challenge. Our studies aim to identify the histological, molecular, and biomechanical alterations of the rotator cuff enthesis with maturation and aging, and develop a novel therapeutic method using three-dimensional (3D) bioprinting technique to regenerate a functional enthesis. Striking variations of the entheses were observed both histologically and biomechanically during the maturation process. The histological features did not show many differences at the insertion site …

BACKGROUND: The purpose of our study is to evaluate if surgical intervention in the setting of an elevated INR or continued use of clopidogrel lead to elevated post-operative mortality and/or morbidity compared to INR reversal or surgical delay.
METHODS: We retrospectively reviewed 1,007 patients age > 55 undergoing hip fracture fixation at our institution over a 10 year span. We placed patients into four groups based upon their anticoagulation status at the time of surgery. Descriptive statistics were utilized to evaluate for differences in mortality rates, blood loss, time to surgery, and wound complications.
RESULTS: Comorbid conditions occurred at a higher …
