Purpose: The study's main objective was to evaluate, in the short-term, the result of the autologous acellular matrix-induced chondrogenesis (AMIC) technique in a selected group of patients with 2-4 cm full-thickness chondral lesions, undergoing hip arthroscopy for femoroacetabular impingement (FAI).
Methods: A retrospective single-center Level IV case series of 25 patients (28 hips) who underwent an arthroscopic hip surgery with a liquid acellular collagen matrix. Inclusion criteria for implantation were FAI diagnosis (cam or pincer type), grade IV chondral lesions (Outerbridge size 2-4 cm); Tönnis stage 0-II, minimum follow-up of 24 months, and 1 year (12-15 months) evaluation with very high field 3-T MRI arthrography.
Introduction: Cobalt toxicity in patients with hip arthroplasty is a rare complication, but it should be considered in those patients who, after a ceramic fracture, were implanted with a metal-on-polyethylene prosthesis. The complete removal of ceramic particles during revision surgery can be complicated. If the bearing surface is replaced with a metal-on-polyethylene prosthesis, these residual ceramic particles may wear down the chrome-cobalt head, producing localised metallosis.

Methods: In this cohort study, we reviewed the clinical registries of patients admitted to a single third-level hospital with the diagnosis of septic arthritis during the period of January 1, 2008, to January 31, 2016.
Results: A total of 63 cases of septic arthritis were identified in which the initial approach for 49 patients was medical (arthrocentesis), whereas the initial approach for 14 patients was surgical (arthroscopy or arthrotomy).
