The main objective of this study is to determine if the P.F.C. Sigma RP-F Knee delivers a greater post-operative range of motion (ROM) compared with the P.F.C. Sigma RP Knee in primary TKA...
The purpose of this scientific study is to clarify whether there is a relationship between the appearance of radiolucent lines in bone-cement interphase of the tibial component of the diff...
The primary objective of this investigation is to evaluate the performance (in terms of post-operative active range of motion at one year) of the P.F.C. Sigma and P.F.C. Sigma Rotating Pla...
The purpose of this study is to evaluate if the P.F.C. Sigma RPF knee accommodates functional stability with a post-operative passive range of motion of greater than 125° of flexion and t...
Primary Research Questions: 1. Do patients with knee osteoarthritis (OA) who undergo total knee replacement with a Sigma rotating platform have better clinical outcomes at 2 years...
Knee osteoarthritis is a major contributor to the global burden of disease. There is a need of reducing knee joint load and to improve balance and physical function among knee osteoarthritis patients.
To examine whether baseline knee joint effusion volume and the change in effusion volume over 1 year are associated with cartilage volume loss, progression of radiographic OA (ROA) over 4 years and ri...
Our study analyzes the association between chemokine-ligand-2 (CCL2) serum concentrations at baseline and knee radiographic OA (knee-rOA), knee-rOA progression, individual radiographic features and kn...
Crepitus is a common clinical feature of knee osteoarthritis. However, the importance of crepitus in the overall clinical presentation of individuals with knee osteoarthritis is unknown.
To study the development of early knee osteoarthritis (OA) in subjects with and without risk factors for knee OA.
Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)
A class of cell surface receptors recognized by its pharmacological profile. Sigma receptors were originally considered to be opioid receptors because they bind certain synthetic opioids. However they also interact with a variety of other psychoactive drugs, and their endogenous ligand is not known (although they can react to certain endogenous steroids). Sigma receptors are found in the immune, endocrine, and nervous systems, and in some peripheral tissues.
A DNA-directed RNA polymerase found in BACTERIA. It is a holoenzyme that consists of multiple subunits including sigma factor 54.
An instrument used to assess the results of rehabilitation from knee injuries, especially those requiring ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION. It measures recovery of knee joint function based on ACTIVITIES OF DAILY LIVING.
Injuries to the knee or the knee joint.
