    IntroductionThe aim of this study was to evaluate the clinical and radiological outcome of the Total Evolutive Shoulder System (TESS) in patients with cuff tear arthropathy and patients in need of a revision arthroplasty.MethodsIn this sequential study, 67 patients (56 non-stemmed, 11 stemmed) were evaluated after a mean follow-up of 17.5 months. The relative Constant and DASH scores, radiological joint geometry changes, complications and postoperative problems, which are not likely to affect the outcome, were evaluated.ResultsA significant increase was noticed for the relative Constant (11.3 vs. 78.8 %) and DASH scores (73.7 vs. 31.8) without significant differences between both etiology groups. Complication rates were similar to previous studies. An aseptic loosening of the non-stemmed humeral component was not noticed in the cuff tear arthropathy group, whereas one case with a loosening was noticed in the revision arthroplasty group. With nine cases (13.4 %), scapular notching rates were very low. On average, the acromiohumeral distance increased by 17 mm and the humeral offset by 13.9 mm; the height of the center of rotation decreased by 4.6 mm and the lateral glenohumeral offset by 6.1 mm, p < 0.05, respectively.ConclusionRegarding the joint geometry, surgery with the TESS system provided adequate distalization and medialization of the humerus and the center of rotation. This corresponds to a good clinical outcome. The use of the surgical opportunity to implant the prosthesis with a relatively low neck-shaft angle might explain the low rates of scapular notching in our series. Regarding the case with a loosening of the humeral component, the surgeon should carefully indicate a stemless version for metaphyseal press-fit fixation in patients with revision arthroplasty.
