Detailed Description

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.
