The purpose of this study is to determine whether patient rehabilitation is equal for patients operated with two different knee implant designs.
The patients are randomized to treatment with either a simple hinge design implant (fixed bearing) or an implant with a mobile bearing polyethylene. This design difference might in principle enable the patients in the latter group to rehabilitate towards a more normal gait pattern.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Health Services Research

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 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...
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...
Comparison of two unicompartmental knee arthroplasties (UKA), to see if Sigma UKA performs equally good as the Oxford UKA. The study focuses on how well the arthroplasty is fixated to the ...
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...
Late presentation of congenital patella dislocation (CPD) with advanced osteoarthritis is very rare. Total knee arthroplasty (TKA) provides a valid treatment option for adults with CPD who have absenc...
Full-Thickness Cartilage Defects Are Important Independent Predictive Factors for Progression to Total Knee Arthroplasty in Older Adults with Minimal to Moderate Osteoarthritis: Data from the Osteoarthritis Initiative.
Knee osteoarthritis (OA) severity on radiographs is not a reliable predictor of symptom severity. The purpose of this study was to determine whether full-thickness defects or OA grade are predictive o...
Knee osteoarthritis with valgus deformity presents a surgical challenge that must be solved during total knee arthroplasty (TKA). In some case whereby ligament imbalance is found, constrained implant ...
A 51-year-old male construction worker with a history of chronic quadriceps tendon rupture presented with no active knee extension and tricompartmental knee osteoarthritis. He underwent simultaneous t...
Does MRI of Knee Cartilage Help to Characterize Osteoarthritis Severity?: Commentary on an article by Joshua S.

Replacement of the knee joint.
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.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
