A Study to Determine the Performance of the Press Fit Condylar (P.F.C.) Sigma RP-F Knee System
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 to demonstrate that the range of motion does not compromise the longevity of the implant.
Primary endpoint is to demonstrate that 90% of patients have a functionally stable knee that can achieve post operative range of motion of 125 degrees or greater.
The secondary endpoint is to investigate the survivorship of the P.F.C. Sigma RP-F knee at 1, 2, 3, 5, 10, 15 and 20 years

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...
The main purpose of this study is to record information from clinical and radiographic examinations and patient assessment questionnaires before surgery and at suitable postoperative inter...
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 the study is to investigate the density, architecture, and perfusion of bone marrow lesions (BMLs) in knee osteoarthritis. We will perform MRI's and QCT's on subjects prior ...
Objective: The increased prevalence of osteoarthritis (OA) in postmenopausal women suggests that changes in either circulating sex steroid concentrations or tissue response to sex steroids may have a ...
There are few reports on bone mineral density (BMD) changes of axial bones after total knee replacement (TKR) due to severe osteoarthritis (OA) of the knee joint and its results are controversial. The...
Background and purpose - It is unclear whether mobile-bearing (MB) total knee arthroplasties reduce the risk of tibial component loosening compared to fixed-bearing (FB) designs. This randomized study...
Objective: Using data from the community-based Johnston County Osteoarthritis Project (JoCo OA), we examined race and gender variations in willingness to undergo, and perceptions regarding, total join...
Total hip replacement and total knee replacement are among the most successful and common surgical procedures in orthopaedics. These operations were traditionally reserved for older, sedentary patient...

Replacement of the knee joint.
Replacement for a 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.

Partial or total replacement of a joint.
Partial or total replacement of one or more FINGERS, or a FINGER JOINT.
