Results of Guide Pin Technique Versus Classic Technique in Open Wedge Proximal High Tibia Osteotomy
Geno varum is defined as knee deformity with changes of natural direction of lower extremities where knee joint center is located at exterior side of mechanical axis of the extremity. The present study was admitted to compare the results of guide pin and classic techniques in open wedge proximal high tibia osteotomy.
Material and
In a cross sectional analytical-descriptive study conducted on the patients candidate for tibia osteotomy surgery, because of geno varum the results of guide pin and classic techniques in open wedge proximal high tibia osteotomy were compared.
In this observational study, 57 patients who were underwent guided pin tibia osteotomy and 31 patients who were treated with classic techniques. There was a difference meaningfully between pre-operation and post-operation Lysholm score in both groups. There was delayed union in two patients of guide pin group and three patients of the classic technique group. Non-union was not seen in any patient. Superficial infection was seen in two patients and in one patients classic group guided pin treated with classic technique. There was intra-articular fracture, in classic group, with no displacement in three patients in guided pin and in 3 patient of classic technique.
According to this study, guide pin technique plays not significant role in decreasing or increasing the intra-articular fracture risk and brings no advantages results in comparison with the classic technique. However, further studies are required.
