Aims.
The function of the upper extremity is highly dependent on correlated motion of the shoulder. The shoulder can be affected by several diseases. The most common are: rotator cuff tear (RCT), shoulder instability, shoulder osteoarthritis and fractures.
Patient outcomes for arthroscopic repairs rotator cuff repairs have been analyzed almost exclusively by means of a single post-operative follow-up date. The purpose of this study was to examine the results of arthroscopic repairs of large rotator cuff tears performed by a single surgeon, both serially and at a two-year endpoint following surgery. Seventeen patients with retracted U-shaped tears involving the supraspinatus were repaired arthroscopically between June 2002 and October 2003 using marginal convergence suturing followed by tendon-to-bone fixation. Patients were assessed at six weeks, three months, six months, one year, and two years following surgery. Each assessment consisted of a medical history, physical examination, and the Western Ontario

Aims.
Introduction and aims: Good outcome for rotator cuff repair has been reported for open, arthroscopically assisted miniopen and arthroscopic techniques. Patient outcomes are affected by tear characteristics, patient factors and surgical experience. Little information is reported in literature on the affect on outcome in the presence of delamination tearing found at surgery. This prospective study compares outcome of miniopen rotator cuff repairs with and without delamination. Method: A prospective analysis between November 2004 and January 2008 allowed data collection on arthroscopically assisted miniopen rotator cuff repairs performed by a single surgeon using the same technique.

Forty-nine patients with a repair of their rotator cuff were evaluated at baseline and at six-months after surgery using four self-reports scales (DASH, Western Ontario

This study prospectively evaluated the functional outcome and strength of patients after rotator cuff surgery. Thirty-three patients were evaluated pre-operatively and post-operatively for one year. Each patient underwent clinical evaluation of shoulder range of motion and machine strength testing. Additionally they completed the SF-36, DASH, Western Ontario
Background.
There is an association between SLAP lesions and laxity of the shoulder. The relationship between rotator cuff disease and hypermobility has also been implied. The purpose of this case-control study was to assess the impact of rotator cuff and superior labral pathologies on degree of glenohumeral translation and range of motion of the shoulder in comparison with individuals with normal shoulders. This study involved individuals with asymptomatic shoulders (control group), and individuals with
Introduction. Differing levels of tendon retraction are found in full-thickness rotator cuff tears. The pathophysiology of tendon degeneration and retraction is unclear. Neoangiogenesis in tendon parenchyma indicates degeneration. Hypoxia inducible factor 1(HIF) and vascular endothelial growth factor (VEGF) are important inducers of neoangiogenesis.
Purpose: To investigate the relationships between vascular endothelial growth factor (VEGF), a proliferation marker (Ki-67) and the cell cycle inhibitor p27 (cyclin-dependent kinase inhibitor p27), in endothelial cells in chronic degeneration of the rotator cuff. Background: The rotator cuff is subject to constant pressure from the head of the humerus. This tends to ‘wring out’ the blood supply resulting in a functionally avascular critical zone, although microvessels can be identified. This zone is the site of degeneration and tears. Attempts at repair under these circumstances could be compromised by inadequate local function of the vascular system particularly sprouting of the capillaries to support the repair process. Methods:
