PURPOSE The purpose of this study was to evaluate at the mRNA level a subset of extracellular matrix molecules relevant during healing and remodeling of rotator cuff tears. TYPE OF STUDY Controlled laboratory study. METHODS Bursal and rotator cuff tissue from the margin of the rotator cuff tear were harvested from 10 patients (mean age, 57.5 +/- 7.3(More)
PURPOSE The purpose of this study was to evaluate the effect of various local anesthetics on chondrocyte viability in articular cartilage by use of a bovine disk model. METHODS Full-thickness bovine cartilage disks were isolated from the condylar surfaces of the radial-carpal joint by use of a 4-mm biopsy punch and were incubated in various concentrations(More)
Ligaments are composed of two major components: cells and extracellular matrix. The cells express gap junction proteins and are arranged into a series of rows that traverse the tissue, suggesting that all the cells of the tissue are functionally interconnected. The results of our study demonstrate that medial collateral ligament (MCL) cells do not have a(More)
Purpose. The purpose of this study was to compare the accuracy of the conventional method for determining the percentage of partial thickness rotator cuff tears to a method using an intra-articular depth guide. The clinical utility of the intra-articular depth guide was also examined. Methods. Partial rotator cuff tears were created in cadaveric shoulders.(More)
