Abstract
Aims: The aim of our work was to measure, the necessary correction angle in unicompartmental knee prosthesis in order to make the patientñs functional result the best following the procedure.
Method: We included all the medial and all the lateral unicompartmental arthroplasties in our department in 1999. For the analysis of the functional results, we have reviewed the patients and recorded the clinical data with the help of the New Jersey Knee Score. We have had the postoperative weight bearing AP knee X-rays also at the same time.
Conclusion: This type of implant can be used with conþdence in medial unicompartmental knee arthroplasties up to 15 degrees of varus deformation preoperatively, according to the early postoperative results. We did not þnd any signiþcant difference in the early functional results between the 10 degrees or less and the more than 10 degrees corrected groups.
