About

Total knee replacement is used in the treatment of patients with knee arthritis, rheumatoid arthritis and other knee disorders. Today, there are basically two designs; It cuts the posterior cruciate ligament (PS) and protects the posterior cruciate ligament (CR). Although there is no clear study suggesting which design is better, research on this subject has increased recently. the investigators aim is to define the superiority of these two designs over each other. Preoperative and postoperative joint range of motion examinations were performed on both knees separately. WOMAC and OXFORD scores were examined separately for both knees.

Full description

Total knee arthroplasty is used to treat patients with osteoarthritis, rheumatoid arthritis, and other knee disorders. Today, there are basically two primary designs; posterior cruciate Substituting (PS) and protects the posterior cruciate -Retaining (CR). However, it is still controversial which approach is good, as both CR and PS have advantages and disadvantages. Proponents of the posterior cruciate retaining system argue that it provides natural stability, wider joint range of motion, better proprioception, and better knee kinematics. In addition, proponents of the posterior cruciate substituting system argue that it provides more harmonious articulation and a wider flexion range.

As a result, although there is no clear study suggesting which design is better, research on this subject has increased recently. Our aim is to define the superiority of these two designs over each other.

Patients with the same stage of knee osteoarthritis in both knees were selected. Total knee arthroplasty was performed in the same session by making the appropriate design for the appropriate knee simultaneously. Preoperative and postoperative joint range of motion examinations were performed on both knees separately. WOMAC and OXFORD scores were examined separately for both knees.
