入选标准

•Male or female subjects may be recruited to the evaluation.
•Age - there are no restrictions relating to age of the patient. The patient's age must be considered suitable by the clinical investigator for a bi-compartmental or tri-compartmental knee arthroplasty using either of the two systems available in the evaluation.
•Subjects who are able to give voluntary, written informed consent to participate in this investigation and from whom consent has been obtained.
•Subjects who, in the opinion of the Investigator, are able to understand this investigation, co-operate with the investigational procedures and are willing to return to the hospital for all the required post-operative follow-ups.
•Subjects who require a bi-compartmental or tri-compartmental knee arthroplasty for primary surgical management of idiopathic osteoarthritis.
•Patients who in the opinion of the Clinical Investigator are considered to be suitable for treatment with a fixed or mobile bearing knee system and who are suitable for patella resurfacing.

排除标准

•Patients who, in the opinion of the Investigator, have an existing condition that would compromise their participation and follow-up in this study.
•Patients who require revision total knee arthroplasty surgery.
•Patients with any tibial deformity requiring tibial component augmentation.
•Patients whom, in the opinion of the Clinical Investigator, require a constrained prosthesis.
•Patients with Rheumatoid Arthritis.
•Patients with a pathology which, in the opinion of the Clinical Investigator, will adversely affect healing.
•Patients with other disorders which, in the opinion of the Clinical Investigator, will / could impair rehabilitation.
•Contra-indications for use of the device, as detailed in the package insert.
•Women who are pregnant.
•Subjects who are known drug or alcohol abusers or with psychological disorders that could effect follow-up care or treatment outcomes.

结局指标

主要结局

To Compare Range of Motion Between Sigma RP and Sigma Fixed Treatment Groups in PCL Sacrificing Arm

时间窗: 1 year

Range of motion is knee flexion (how far the patient can bend their knee) minus knee extension (how far the patient can straighten their knee). The result of this subtraction is the range of motion (bending and straightening) for that knee.
