Mobile-bearing Unicondylar Knee Arthroplasty Clinical Trial
Unicondylar knee arthroplasty (UKA) is a proven procedure in patients suffering from
unicompartmental knee osteoarthritis. Two different types of UKA design are available - both
with different pros and cons. The so-called 'mobile-bearing UKA' requires the removal of an
additional amount of cartilage and bone close to the implantat. It is unclear whether this
is of clinical relevance.
We speculate that the amount of cartilage/bone removal is related to the clinical outcome of
the UKA-surgery.
In patients receiving a mobile-bearing UKA that amount of cartilage/bone removal is measured
during the surgery. The clinical success of the procedure will be determined with certain
knee questionnaires (Kujala & KOOS)preoperatively, 3 months postoperatively, 6 months
postoperatively and 1 year postoperatively. Additionally, the so-called bone-remodelling
around that area of resected cartilage and bone will be measured (SPECT-CT) postoperatively.
The three variables (removed amount of cartilage/bone; clinical success with regard to the
questionnaires; bone remodelling) are then analyzed with statistical methods to find out
potential assoziations among them.
