Graft selection in arthroscopic anterior cruciate ligament reconstruction.

Background: anterior cruciate ligament (ACL) surgical reconstruction is performed with the use of an autogenic, allogenic or synthetic graft. The document issued by the Italian National Guidelines System (SNLG, Sistema Nazionale Linee Guida) at the National Institute of Health aims to guide orthopaedic surgeons in selecting the optimal graft for ACL reconstruction using an evidence-based approach.

Materials And Methods: A monodisciplinary panel was formed to define a restricted number of clinical questions, develop specific search strategies and critically appraise the literature using the grading of recommendations assessment, development, and evaluation (GRADE) method.

Severe heterotopic ossification after total hip arthroplasty in Schnitzler syndrome.

Schnitzler syndrome is a rare disorder characterized by monoclonal IgM gammopathy, urticaria, recurrent fever, evidence of inflammation, bone pain, and arthralgia. We present the case of a patient affected by Schnitzler syndrome who developed Della Valle type C heterotopic ossification after total hip arthroplasty. A relationship between the underlying syndrome and the considerable heterotopic ossification observed is compatible with the patient's clinical history and incidental findings.
