Summary

This trial will compare three different types of knee replacements to see which is most effective in terms of movement, pain, and function.

Who is the study for?
This trial is for men and non-pregnant women aged 50-75 with Non-Inflammatory Degenerative Joint Disease needing knee replacement. They must be able to follow the study's procedures and have signed consent. Excluded are those with a BMI ≥ 40, recent or upcoming lower extremity surgeries, sensitivity to device materials, infections in the knee, or severe knee deformities.
What is being tested?
The study tests if Journey II knee implants lead to better outcomes than standard Stryker and Zimmer implants in terms of movement, walking patterns, pain relief, and function post-surgery.
What are the potential side effects?
While not specified here, typical side effects from knee replacement surgery can include pain at the site of operation, swelling around the knee joint area, stiffness in the operated leg or difficulty moving it.
