Surgical management of hip prosthetic failure in metallosis: A case series and literature review.

Local and remote complications can be observed in hip prosthesis failures associated with metallosis. Structural changes in the periprosthetic bone and soft tissues may not always be precisely assessed preoperatively due to metal artifacts. The unpredictability of the damage extension, potentially leading to complex and insidious surgeries, requires the availability of alternative surgical plan(s) for the reconstruction of the joint. The aim of the study is to present and analyze, with the literature data support, practical tips for the revision of the prosthetic components, the management of ARMD and of intraoperative complications in the unusual scenario of metallosis.

Surgical treatment of talar osteo-chondral lesions with micro-fractures, mesenchymal cells grafting on membrane, or allograft: Mid-term clinical and magnetic resonance assessment.

Talar dome osteo-chondral lesions (OCL) are defects of the cartilaginous surface and subchondral bone often associated with sport practice. This retrospective observational work has the purpose of assessing: a) The clinical outcomes in the patients study group and in the three sub-groups; b) medium-term morphological and qualitative outcomes of the newly formed tissue by magnetic resonance imaging; c) if there is the correlation between new formed tissue clinical, morphological RM evaluation and qualitative clinical outcomes.
