Osteochondral fracture of lateral femoral condyle can result from support and other twisting injuries of the knee. Arthroscopy is a better diagnostic and therapeutic tool as standard radiographs can mislead regarding the size and location of the fragment. If fragment is large and displaced, arthrotomy may become necessary. We present a case of large osteochondral fracture of lateral femoral con...

Pediatric elbow fractures can be challenging to manage. Compression of the medial column in Gartland Type I and Type II supracondylar fractures must be reduced to prevent varus deformity. Gartland Type III fractures may be stabilized with two lateral pins or a medial lateral cross-pin technique. Non-displaced lateral condyle fractures require vigilant follow-up. Open reduction of displaced late...

A "Fishtail deformity" is one of the well-known complications following pediatric lateral condyle or supracondylar fractures of the humerus. We herein report a case of medial condyle fracture (Kilfoyle type III) in an 11-year-old boy. He had a transient "fishtail deformity" of the trochlear groove after open reduction and internal fixation. As occurred in the current case, the bone remodeling a...

Purpose Anterior cruciate ligament (ACL) rupture has been associated with early occurrence of osteoarthritis (OA), which was originally believed to be due to instability derived from ACL insufficiency. However, recent studies showed more than half of the patients who had ACL reconstruction will develop OA changes within 10 years after an ACL rupture. These findings suggest that the initial inju...

We assessed the possible association between an aggressive intercondylar notchplasty and histopathologic, radiographic, and gait changes to the knee. Three groups of six adult greyhounds were observed for 6 months. Group I dogs had a sham operation. Group II dogs had a 4-mm notchplasty of the lateral femoral condyle where it articulates with the lateral tibial spine. Group III dogs had a 7- to ...

Chondral lesions frequently occur in different topographic locations of the knee. This study evaluated the functional properties among the articulating surfaces of the tibiofemoral and patellofemoral joints, and whether neo-cartilage engineered using chondrocytes from different knee locations would reflect these differences. The biomechanical properties of bovine cartilage isolated from eight l...

BACKGROUND Although conservative treatment is a well-established method for treating nondisplaced and minimally displaced (< or =2 mm) fractures of the lateral humeral condyle in children, there is still great uncertainty concerning the rate and time course of subsequent displacement. Therefore, the appropriate frequency of radiographic follow-up remains unclear. The aim of the study was to det...

PURPOSE To investigate the etiologic factors related to refractures of the upper extremity in children. PATIENTS AND METHODS Eighteen refractures were divided into three groups according to the location of the initial fractures. They were analyzed in terms of the type of refractures, fracture patterns, and the existence of an underlying deformity. RESULTS Of nine supracondylar fractures of ...

We present 2 cases of severe, rapidly progressive chondral disease in the lateral compartment within 12 months after meniscectomy. In both cases, the lateral compartment was salvaged with simultaneously performed cartilage repair techniques and meniscal transplantation. The first case is of a 16-year-old boy who suffered a complex irreparable posterior horn lateral meniscus tear that was treate...

We studied active flexion from 90 degrees to 133 degrees and passive flexion to 162 degrees using MRI in 20 unloaded knees in Japanese subjects. Flexion over this arc is accompanied by backward movement of the medial femoral condyle of 4.0 mm and by backward movement laterally of 15 mm, i.e., by internal rotation of the tibia. At 162 degrees the lateral femoral condyle lies posterior to the tibia.
