Assessment of Periprosthetic Bone Mineral Density in Patients Undergoing Total Knee Prosthesis of Different Design
Assessment of Bone Mineral Density at the Interface With the Femoral and Tibial Components in Patients Undergoing Total Knee Prosthesis of Different Design and Material
Istituto Ortopedico Rizzoli
50 participants
Aug 30, 2023
INTERVENTIONAL
Conditions
Summary
compare changes in BMD via DXA at the level of the femoral and tibial periprosthetic bone between two groups of patients undergoing cemented TKA of different design (posterior stabilization vs posterior cruciate preservation) with proms at a 2-year follow-up.
Eligibility
Inclusion Criteria3
- Patients aged ≥ 45 years
- Patients 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:
- to. Primary or secondary osteoarthritis b. Collagen disorders and/or avascular necrosis of the femoral condyle c. Moderate valgus, varus or flexion deformities (HKA within ±10°, flexion contracture <10°) 3. Patients consenting and able to complete planned study procedures and follow-up assessments 4. Patients informed about the nature of the study who signed the "informed consent" approved by the ethics committee.
Exclusion Criteria3
- Patients aged < 45 years;
- Patients who have already undergone hip or knee arthroplasty ankle, previous osteotomy, with severe axial deformities or suffering from rheumatoid arthritis, diabetes or neuromuscular diseases. In this way, homogeneity of the investigated cohort will be guaranteed;
- Pregnant women. -
