Evaluation of Patellar Position before and After Medial Opening Wedge High Tibial Osteotomy: Radiographic and Computed Tomography Findings

چکیده
INTRODUCTION Genovarum is a common orthopedic problem. Its optimal prompt treatment is an issue of importance. AIM This study was conducted to determine the radiographic changes in patella bone before and after open wedge high tibial osteotomy. MATERIAL AND METHODS In this quasi-experimental study, 43 patients were enrolled and underwent open wedge high tibial osteotomy and the radiographic and CT-scan indices including Q-Angle, Congruence Angle, Insall-Salvati index, and TTTG were measured and compared before and after surgery. RESULTS The result revealed that all indices including Q-Angle, Congruence Angle, Insull-Salvati index, and TTTG were not significantly differed across the study (P > 0.05). There was no difference between DLFA values before and after the operation (P> 0.05), while MPTA values were significantly different before and after operation (p <0.001). CONCLUSIONS Totally it may be concluded that imaging indices are not differed after open wedge high tibial osteotomy and monitoring for them is not necessary and they would have no prognostic role.

Modified retro-tubercle opening-wedge versus conventional high tibial osteotomy.
Despite the fact that common surgical techniques for the treatment of genu varum usually correct the malalignment in the affected knee, these methods have significant complications and cause problems in the long term. Retro-tubercle opening-wedge high tibial osteotomy is among the newer techniques for the treatment of genu varum. The goal of this study was to compare the results of retro-tuberc...
متن کاملHigh Tibial Valgus Osteotomy: Closing, Opening or Combined? Patellar Height as a Determining Factor
BACKGROUND According to the literature, closing and opening wedge high tibial valgus osteotomies can raise or lower the patella, and diffèrent methods of patella height measurement show similarly conflicting results. Clarification of this was thought to be important because there is much literature describing morbidity secondary to patella alta or patella infera (baja). Effects on tibial slope ...
متن کاملPatellar height and the inclination of the tibial plateau after high tibial osteotomy. The open versus the closed-wedge technique.
Our aim was to compare the degree of patellar descent and alteration in angle of the inclination of the tibial plateau in lateral closing-wedge and medial opening-wedge high tibial osteotomy (HTO) in 51 consecutive patients with osteoarthritis of the medial compartment and varus malalignment. Patellar height was measured by the Insall-Salvati (IS) and the Blackburne-Peel (BP) ratios. The tibial...
متن کاملHigh tibial osteotomy: closed wedge versus combined wedge osteotomy
BACKGROUND High tibial osteotomy is a common procedure to treat symptomatic osteoarthritis of the medial compartment of the knee with varus alignment. This is achieved by overcorrecting the varus alignment to 2-6° of valgus. Various high tibial osteotomy techniques are currently used to this end. Common procedures are medial opening wedge and lateral closing wedge tibial osteotomies. The latera...
متن کاملOpening wedge tibial osteotomy: the 3-triangle method to correct axial alignment and tibial slope.
BACKGROUND Although a change in tibial slope may occur during a medial opening wedge osteotomy, calculations have not been defined to address this problem. The authors investigated geometric factors important to correct axial alignment and tibial slope during osteotomy. PURPOSE To calculate, through 3-dimensional analysis of the proximal tibia, how the angle of the opening wedge along the ant...
