[Complications related to implants in arthroscopic shoulder surgery].
With the increase in shoulder arthroscopies are increased complications related to shoulder implants frequently used for arthroscopic rotator cuff repair and shoulder stabilisation. The biggest problem is malpositioning of the suture anchor, which might lead to persistent pain, serious cartilage damage, decreased range of motion, and failure of the reconstruction, resulting in revision surgery. Especially in osteoporotic bone, it is important to choose an implant that provides sufficient mechanical strength. Other possible complications are related to the sutures of the anchor. Suture damage or accidental removal of the sutures from the anchor could leave them useless in situ. Tangling of the sutures, especially in massive reconstructions of the rotator cuff, can lead the surgeon to switch to an open technique. Compared with metal implants, bioabsorbable implants have advantages concerning possible revision surgery. However, implant costs, anchor hole enlargement, and possible higher failure rates compared with metallic implants should be considered. A rare but serious complication is allergic reaction to the implant.
