Current Total Knee Designs: Does Baseplate Roughness or Locking Mechanism Design Affect Polyethylene Backside Wear?

Tibial baseplate roughness and polyethylene-insert micromotion resulting from locking-mechanism loosening can lead to polyethylene backside wear in TKAs. However, many retrieval studies examining these variables have evaluated only older TKA implant designs.

With the increasing number of patients with knee osteoarthritis undergoing TKAs in China, there is a clear need for a valid, short, joint-specific patient-reported outcome measure such as the Oxford Knee Score (OKS).

Alloy Microstructure Dictates Corrosion Modes in THA Modular Junctions

Adverse local tissue reactions (ALTRs) triggered by corrosion products from modular taper junctions are a known cause of premature THA failure. CoCrMo devices are of particular concern because cobalt ions and chromium-orthophosphates were shown to be linked to ALTRs, even in metal-on-polyethylene THAs. The most common categories of CoCrMo alloy are cast and wrought alloy, which exhibit fundamental microstructural differences in terms of grain size and hard phases. The impact of implant alloy microstructure on the occurring modes of corrosion and subsequent metal ion release is not well understood.

Moving Forward Through Consensus: A Modified Delphi Approach to Determine the Top Research Priorities in Orthopaedic Oncology

30th August 2017, Clinical Research

Several challenges presently impede the conduct of prospective clinical studies in orthopaedic oncology, including limited financial resources to support their associated costs and inadequate patient volume at most single institutions. This study was conducted to prioritize research questions within the field so that the Musculoskeletal Tumor Society (MSTS), and other relevant professional societies, can direct the limited human and fiscal resources available to address the priorities that the stakeholders involved believe will have the most meaningful impact on orthopaedic oncology patient care.
