No Difference Between Trabecular Metal Cones and Femoral Head Allografts in Revision TKA: Minimum 5-year Followup.
TLDR
Femoral head allografts and trabecular metal cones can both be used for the management of Anderson Orthopaedic Research Institute Types 2 and 3 defects and there was no difference in pain, function, or repeat revision when comparing these two techniques.Abstract:
Background
Encouraging clinical results have been reported with the use of femoral head structural allografts and, more recently, trabecular metal cones for the management of large structural defects of the femur and tibia during revision total knee arthroplasty (TKA). However, to our knowledge, there are no published studies comparing these two techniques.read more

Porous Tantalum and Titanium in Orthopedics: A Review
TL;DR: The directions of orthopedic porous metal development were proposed from the clinical view based on the rapid progress of additive manufacturing, and controlled design of both macroscopic anatomical bionic shape and microscopic functional bionic gradient porous metal should be developed as the focus.

Metaphyseal cones and sleeves in revision total knee arthroplasty: Two sides of the same coin? Complications, clinical and radiological results—a systematic review of the literature
TL;DR: Metaphyseal cones and sleeves represent a viable option in management of type IIb and III AORI bone defects in aseptic and septic TKAr with overlapping survival rate and further high-quality long-term studies would better clarify complications, clinical and radiological results of these promising techniques in revision total knee arthroplasty.

Clinical Survivorship of Aseptic Revision Total Knee Arthroplasty Using Hinged Knees and Tantalum Cones at Minimum 10-Year Follow-Up
TL;DR: Porous tantalum cones in revision TKA exhibited no favorable but reasonable long-term durability, and rotating-hinge designs should be used whenever possible to reduce the risk of aseptic loosening.
Management of metaphyseal bone loss in revision knee arthroplasty.
TL;DR: The treatment of bone defects in revision TKAs has evolved during the last years providing different options with good results at a short/medium term follow up, with the increasing revision burden.

The role of rotating hinge implants in revision total knee arthroplasty
TL;DR: Hinged implants continue to have a place in revision surgery to solve major instability or to obtain stable bone fixation of an implant when the metaphysis is filled with bone grafts or porous devices.

A 12-Item Short-Form Health Survey: Construction of Scales and Preliminary Tests of Reliability and Validity
TL;DR: Twenty cross-sectional and longitudinal tests of empirical validity previously published for the 36-item short-form scales and summary measures were replicated for the 12-item Physical Component Summary and the12-item Mental Component Summary, including comparisons between patient groups known to differ or to change in terms of the presence and seriousness of physical and mental conditions.

Questionnaire on the perceptions of patients about total hip replacement
TL;DR: In this article, a 12-item questionnaire for patients having a total knee replacement (TKR) was developed and a prospective study of 117 patients before operation and at follow-up six months later, asking them to complete the new questionnaire and the form SF36.

TL;DR: A consensus was reached by at least 90% of participants that the following 4 domains should be evaluated in future phase III trials of knee, hip, and hand OA: pain, physical function, patient global assessment, and, for studies of one year or longer, joint imaging.

TL;DR: Revision knee data from six joint arthroplasty centers were compiled for 2010 and 2011 to determine mechanism of failure and time to failure, and polyethylene wear is not a leading failure mechanism and rarely presents before 15 years.
