Total knee arthroplasty (TKA) remains the gold standard for end-stage knee osteoarthritis. The prevalence of stiffness after this procedure described in literature varies from 1.3% to 5.3%. The causes of arthrofibrosis after total knee arthroplasty are multifactorial. Revision TKA is a successful procedure when performed for loosening, instability, mechanical implant failure, or infection. The results of revision TKA for idiopathic arthrofibrosis and stiffening are however less favorable. ⋯ Our data show that revision arthroplasty of the stiff knee using a rotating hinged device can provide excellent results in selected cases. To date, this is the first study to describe the difference in outcome between revision total knee arthroplasty for idiopathic arthrofibrosis using a hinged or a constrained condylar knee device.

A source of myofascial pain and myofascial trigger points (MTrPs) in muscles of the knee area could play a crucial role in the management of pain in osteoarthritis patients. The aim of this study was to describe and compare demographic, clinical and myofascial pain syndrome characteristics in older adults with knee osteoarthritis by sex and age distribution. ⋯ The demographic and clinical features of older adults with knee osteoarthritis may be influenced by sex and age distribution. Nevertheless, the myofascial pain syndrome associated with knee osteoarthritis did not seem to be related to sex or age distribution.
