Introduction:
Aim of this study was to compare clinical results after open wedge HTO (OW-HTO and medial unicondylar joint replacement (UKA) in patients aged between 55 and 65.
Materials And Methods:
Fifty-four patients aged between 55 and 65 years with medial OA and varus malalignement who had been treated by either OW-HTO or UKA could be included. Minimum follow up was 5 years. The HSS knee score and the KOOS were used to evaluate clinical outcome.
Results:
There was no difference in the revision rate, the HSS knee score and the KOOS subscales Sports/Rec and ADL between the OW-HTO and UKA group. However, the KOOS subscales pain, Symptoms and QoL were significantly better in the UKA group compared to the OW-HTO.
Conclusions:
The results of this study showed that 5 years after surgery patients after UKA had less residual pain and symptoms than patients after UKA. These advantages might result in a higher quality of life.
