Active clinical trials for "Osteoarthritis"

Randomized clinical outcome study of two rotating hinge knee prosthesis in knee surgery. Hypothesis: No difference in the clinical outcome for 1 year after the operation. Clinical follow-ups at 3, 10, 90 and 360 days after surgery. Measurement of clinical parameters

The purpose of this observational study is to investigate the prevalence and risk factors of bone degenerative diseases

The investigators are comparing the range of movements the knees of patients who had total knee replacement surgery for knee osteoarthritis. In the study arm, the implant used was a Sigma Cruciate Retaining (CR) Press Fit Condylar (PFC) 150, which is a high flexion knee system designed to combine function with wear resistance. It can accommodate up to 150 degrees of knee flexion. In the cohort arm, the implant used was the standard Sigma CR which can accommodate up to 120 degrees of flexion.
