Comparative Evaluation of Uniplanar versus Biplanar Valgus Distal Femoral Osteotomy in Genu Varum Deformity: A Prospective Randomized Clinical Trial with 3 years Follow-up
Randomized trial compares outcomes of uniplanar versus biplanar osteotomy in patients with genu varum, indicating significant advantages in patient satisfaction for uniplanar technique.
Key Points
This trial aimed to compare clinical and radiographic outcomes of uniplanar versus biplanar valgus distal femoral osteotomy in treating genu varum.
Prospective randomized double-blind clinical trial with 80 patients
Randomization to uniplanar (n=40) or biplanar (n=40) techniques
Follow-up for a minimum of 36 months assessing functional scores and radiographic alignment.
Both techniques improved all functional scores (IKDC, KOOS, KSS) and radiographic alignment with no statistically significant differences (p>0.05)
Higher patient satisfaction in uniplanar group (70.3% very satisfied) vs. biplanar group (47.4%, p=0.048)
Biplanar group showed a trend towards shorter time to radiographic union (6.4 vs. 7.0 months, p=0.09).
