[Open reconstruction of the rotator cuff].

Success rates relating to relief from pain and improved function following open reconstruction of the rotator cuff have been documented in many studies. At least for small to medium-size tears the question currently arises of whether an arthroscopic repair would not also give good treatment results. At present, however, the results of arthroscopic repair are not yet comparable to those yielded by the open techniques, at least in terms of recurrent defects especially in the case of massive tears (affecting more than two tendons). Open surgical repair is currently still recommended for all patients who require maximal postoperative function and strength and for elderly patients. Open repairs have a lower rate of re-rupture than arthroscopic repairs, but arthroscopic repair offers the benefits of lower morbidity. The decision on which technique is indicated should be made by an experienced surgeon with special training in this area and with due consideration for newer aspects in diagnostic imaging techniques, so as to avoid unsatisfactory results. In certain cases of irreparable cuff tears affecting two tendons and with fatty infiltration of the muscle and substantial loss of function muscle transfer can be considered in active patients; this can offer some functional improvement in the medium to long term, but do not lead to full restoration of function.
