Lower limb equalization with percutaneus epiphysiodesis of the knee joint area
Introduction:
Epiphysiodesis has become one of the most popular methods in the treatment of leg length discrepancy (LLD) due to its surgical simplicity, short hospitalization time, and a low risk of complications.
Patients And Methods:
A retrospective analysis was performed on 34 patients treated for LDD with percutaneus epiphisiodesis of the distal femur and/or the proximal tibia. The mean discrepancy was 2.8 cm. The outcome evaluation method was based on Kemnitz et al.
Results:
Based on the Kemnitz criteria, 23 (67.6%) patients experienced good results, while 2 (5.9%) satisfactory and 9 (26.5%) poor results. In 47% of patients, swellings of the knee joint were observed in the postoperative period. One serious complication - varus deformity of 10 degrees in femur occurred in the follow-up period.
Conclusions:
Percutaneous epiphysiodesis is a simple method of the LLD correction, with a low rate of complications and applicable in cases of late LDD diagnosis.
