Background: This systematic review gives an overview of guidelines and original publications as well as the evidence on which the currently proposed indication criteria are based. Until now such a state-of-the-science overview was lacking.

Methods: Websites of orthopaedic and arthritis organizations (English/Dutch language) were independently searched by two authors for THA/TKA guidelines for OA. Furthermore, a systematic search strategy in several databases through August 2014 was performed. Quality of the guidelines was assessed with the AGREE II instrument, which consists of 6 domains (maximum summed score of 6 indicating high quality). Also, the level of evidence of all included studies was assessed.

Results: We found 6 guidelines and 18 papers, out of 3065 references. The quality of the guidelines summed across 6 domains ranged from 0.46 to 4.78. In total, 12 THA, 10 TKA and 2 THA/TKA indication sets were found. Four studies stated that no evidence-based indication criteria are available. Indication criteria concerning THA/TKA consisted of the following domains: pain (in respectively 11 and 10 sets), function (12 and 7 sets), radiological changes (10 and 9 sets), failed conservative therapy (8 and 4 sets) and other indications (6 and 7 sets). Specific cut-off values or ranges were often not stated and the level of evidence was low.

Conclusion: The indication criteria for THA/TKA are based on limited evidence. Empirical research is needed, especially regarding domain specific cut-off values or ranges at which the best postoperative outcomes are achieved for patients, taking into account the limited lifespan of a prosthesis.

Preservation of Liver Graft Using the Hypothermic Oxygenated Perfusion (HOPE) System: A single-center experience.

Transplant Proc

January 2025

BioBizkaia Research Health Institute, Barakaldo, Bizkaia, Spain; Hepatobiliary Surgery and Liver Transplantation Unit, Cruces University Hospital, Bilbao, Spain. Electronic address:

Introduction: The hypothermic oxygenated perfusion (HOPE) system has been developed to improve the quality of previously considered suboptimal liver grafts, reduce complications, and increase the number of available donors. The aim of this study is to evaluate the results since its implementation in the liver transplant (LT) program at our center.

Materials And Methods: We conducted a retrospective descriptive analysis of all LTs with HOPE from August 2022 to November 2023 with a minimum follow-up of 3 months.

Purpose Of Review: Baclofen, a muscle relaxant that reduces the release of excitatory neurotransmitters in the pre-synaptic neurons stimulating inhibitory neuronal signals in post-synaptic neurons, has been around for over 5 decades. Baclofen is used primarily for spasticity and since 1982, has had a role as an intrathecal agent. In the present investigation, we review research trends and updates on safety and efficacy of intrathecal baclofen (ITB) pumps.
