We reviewed 34 knees in 24 children after a double-elevating osteotomy for late-presenting infantile Blount's disease. The mean age of patients was 9.1 years (7 to 13.5). All knees were in Langenskiöld stages IV to VI. The operative technique corrected the depression of the medial joint line by an elevating osteotomy, and the remaining tibial varus and internal torsion by an osteotomy just belo...

We present a case of an ipsilateral tibial shaft fracture and a distal tibial triplane fracture with an intact fibula in a 14-year-old boy. Computed tomography revealed the distal tibial triplane fracture with a 2.6-mm displaced Tillaux fragment and a posterior malleolar shear fragment. Open reduction and internal fixation was performed to optimise healing and outcome. This is a rare injury, fo...

Background: Genu valgum usually originates from a deformity of distal femur that is often corrected by distal femoralvarus osteotomy. The osteotomy includes both components of angulationcorrection and translation because the siteof osteotomy is not commonly at the apex of deformity. Improvement of patellar tracking not only depends on valguscorrection, but also it may be partially due to centra...

We experienced two cases of atypical lateral dislocations of meniscal bearing in UKA (unicompartmental knee arthroplasty) without manifest symptoms. The dislocated bearing, which jumped onto the wall of tibial components, was found on radiographs in periodic medical examination although they could walk. Two thicker size bearing exchanges were promptly performed before metallosis and loosening o...

Exposure in a total knee arthroplasty can be challenging regardless of whether it is a difficult primary or a revision. Various techniques both proximal and distal to the patella have been described and implemented to gain exposure and improve knee flexion. When patella eversion is not possible due to previous surgery or severe preoperative knee flexion contracture, a coronal tibial tubercle os...

The primary indications for performing a medial closing wedge distal femoral osteotomy are valgus knee malalignment, lateral compartment overload, meniscus insufficiency, and/or osteoarthritis or cartilage damage. Without correction of this there is an increased risk chondral damage in the and patellofemoral knee. optimal candidates procedure young, active individuals with moderate to severe ar...

BACKGROUND This study aimed to investigate, by means of finite element analysis, the effect of a drill hole at the end of a horizontal osteotomy to reduce the risk of lateral cortex fracture while performing an opening wedge high tibial osteotomy (OWHTO). The question was whether drilling a hole relieves stress and increases the maximum correction angle without fracture of the lateral cortex de...

background:  distal femur wedge osteotomies for varus or valgus alignment of the lower extremity could be done in either uniplanar or biplanar fashion.:union: time and stability of the osteotomy site has been considered important in this anatomic region. in this study, clinical and radiographic findings of biplane distal femur osteotomy were reported. methods: clinical, functional, and radiolog...

INTRODUCTION: Historically, tibial tunnel creation in ACL reconstruction was performed by antegrade insertion of a tibial guide pin followed by antegrade reaming from the anteromedial tibial metaphysis (distal aperture) to the tibial plateau (proximal aperture). In the last few years retrograde reaming has been introduced.[1, 2] It has been theorized that the retrograde tibial tunnel drilling t...
