Comparison of Early Clinical and Radiological Results and Patient Satisfaction of Mobile and Fixed Insert Unicondylar Knee Prosthesis

Comparison of the early clinical and radiological results and patient satisfaction of the mobile and fixed insert unicondylar knee prostheses routinely used in the clinic.

Unicondylar knee prosthesis operation will be performed on patients with unicompartmental knee arthrosis who apply to our clinic. Patients will be randomized to use mobile or fixed inserts. After 1 year of follow-up, SF-36, KOOS and HSS scores will be taken to examine the clinical satisfaction of the patients. In addition, radiological evaluation will be made for the presence of osteolysis at the tibial implant interface between both groups.
