Summary

Several authors and large registries have suggested the potential for an increased risk of all-cause revision with the use of posterior cruciate-substitution (PS) total knee arthroplasty (TKA). The purpose of the current study was to compare posterior cruciate retaining (CR) and PS implants with respect to the functional and radiographic results, prevalence of osteolysis, revision rates and survivorship.

Conditions

  • Osteoarthritis, Knee
  • Arthropathy of Knee Joint

Interventions

PROCEDURE

Total knee replacement with cruciate retaining femoral component

To perform the total knee replacement, the knee joint is anatomically dissected, and thin portions of bone and cartilage is resected to accommodate a metallic implants. Implants are fixed to patients' bone with bone cements. Many designs for femoral component designs are available. In the present study, two types of implants, one CR(cruciate retaining), where the posterior cruciate ligaments are retained, and one PS(Posterior cruciate substituting), where the posterior cruciate ligaments are resected, will be compared. To make the comparison more reliable, the same kind of implants will be used, so that the major portions of femoral component design remains the same and the tibial component remains the same. Only the cruciate ligament parts are different. For this arm of intervention, CR knee will be used, so posterior cruciate will remain intact after the surgery and still function to aid in the knee stability.

PROCEDURE

Total knee replacement with cruciate substituting femoral component

To perform the total knee replacement, the knee joint is anatomically dissected, and thin portions of bone and cartilage is resected to accommodate metallic implants that has similar contours of a native knee. Implants are fixed to patients' bone with bone cements. This procedure will use the femoral component that sacrifice the posterior cruciate ligament and having a box area with a post, so that "cam-post" mechanism of implants can mimic the function of the posterior cruciate ligament. To make the comparison more reliable, the same kind of implants will be used, so that the major portions of femoral component remains the same. The tibial component will remain the same design. Therefore, only the cruciate ligament parts will be different.
