Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Male and female subjects 50 years of age or older and less than 85 years of age (\>50 and \<85 years) who are candidates for primary cemented total knee replacement based on physical examination and medical history, including diagnosis of severe knee pain and disability due to at least one of the following causes:

* to. Primary or secondary osteoarthritis
* b. Collagen disorders and/or avascular necrosis of femoral condyle
* c. Moderate valgus, varus or flexion deformities (HKA between ± 10°, flexion contracture \<10°) -
2. Patients consent and able to complete scheduled study procedures and follow-up assessments.
3. Patients informed about the nature of the study who signed the "informed consent" approved by the ethics committee.

Exclusion Criteria

* Simultaneous participation in other studies
