Brief summary
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 intervals to assess the functioning and symptomology of each knee following surgery. In addition, any adverse events or complications are to be recorded, and any device failures or early revisions are to be recorded and reported directly to the Sponsor. The data are to be used in an evaluation of the performance of the P.F.C. Sigma knee implants over a minimum of 5 years.
Detailed description
The primary outcome measures are detailed above in the brief summary. Secondary outcomes are any adverse events or complications and any device failures or early revisions to be recorded and reported.

Inclusion criteria
* Patients who have given voluntary written informed consent to participate in this study. * Patients for whom primary Total Knee Replacement is indicated due to degenerative joint disease, including rheumatoid arthritis, osteoarthritis, avascular necrosis, and post-traumatic arthritis, which is causing pain, deformity, or limitation of function uncontrolled by medical treatment. * Patients who, in the opinion of the Investigator, are able to understand this study, co-operate with the investigational procedures and are willing to return to the hospital for all the scheduled post-operative follow-ups. * Male or female patients who are skeletally mature and for whom an appropriate size of device is available.
