Abstract
The purpose of this study was to clarify the short-term results of TKA with wedge-type metal augmentation for knees with bone defects of the medial tibial condyle (4 OA and 1 RA) treated in 2008. Five patients (1 man and 4 women) were followed up for 4 to 10 months (mean : 7.6 months) after surgery. The mean age was 76.6 years (range : 70 to 83 years). NexGen LPS-Flex-type TKA with an extension stem was used for all patients.
JOA score was improved from 35.0 before surgery to 75.5 after surgery in OA patients, and from 41 to 85 in RA patient. The knee extension was improved from −22° to −7° and the knee flexion was improved from 108° to 130°. On radiography, FTA was improved from 202° to 175°.α angle was 95.5°,β angle was 89.1°,γ angle was 0.6°, and δ angle was 86.5° after surgery.
Good short-term results were obtained using TKA with wedge-type metal augmentation for knees with bone defects of the medial tibial condyle.
