This study establishes a "structure theory," including topology, common properties, synthesis, and analysis of various F-DOF, ñ-link, K-independent loops, and V-multiple joint factors for open, closed, and mixed kinematic chains with simple and multiple joints (if any).
While OA in a specific joint (monoarticular OA) may result from acute trauma [ 27] or from mechanical stress [ 38] to the joint, OA with multiple joint involvement (polyarticular OA) might be dominated by systemic factors to which all joints would be equally susceptible.
Therefore, our aim was to apply factor analytic methods to radiographic OA (rOA) grades across multiple joint sites, representing both presence and severity, to quantify the burden of rOA.
Some patients require multiple joint replacements.
His wife, Rhonda, suffers from osteoarthritis and has undergone multiple joint and bone surgeries.
We were therefore interested in applying factor analytic methods to Kellgren-Lawrence global (KL, 0 to 4) and Burnett atlas joint features (0 to 3) radiographic grades [ 22, 23] across multiple joint sites as a way to formulate composite scores of multi-joint rOA, encompassing both presence and severity, using data from participants in the Johnston County Osteoarthritis Project (JoCo OA).
Joint hypermobility is also common, including congenital hip dislocation and recurrent or multiple joint subluxations.
Multiple joint involvement was common, with the median number of joints affected being four.
Thus, treatment of a single joint by local delivery of the IFN-β gene could protect multiple joints.
In the transgenic tumor necrosis factor (TNF) mouse model, which is characterized by inflammation in multiple joints including the sacroiliac joints, intraarticular joint fusion and ankylosis in the sacroiliac joints can be induced by blockade of dickkopf-1 (DKK-1) – an antagonist of the wingless (wnt) pathway [ 6].
