BACKGROUND Debate exists on the proper relation of the anterior cruciate ligament (ACL) footprint with the intercondylar notch in anatomic ACL reconstructions. Patient-specific graft placement based on the inclination of the intercondylar roof has been proposed. The relationship between the intercondylar roof and native ACL footprint on the tibia has not previously been quantified. HYPOTHESIS...

abstract   background: the purpose of this study was to evaluate the significance of the q angle with respect to the patella position. we assess the correlation between the q angles (calculated by clinical exam) in different positions and ct indices (with more impression on tttg).   method: atotal number of 68 knee joints of 50 cases entered the study. clinical examination was used to measure q...

The tibial tubercle (interchangeable with tuberosity) is the most distal anchor of the extensor mechanism and can serve as a tool in altering patellofemoral (PF) mechanics. Known collectively as distal realignment procedures, osteotomies of the tibial tubercle are a useful method to treat a variety of PF conditions by allowing coronal, axial, and sagittal plane adjustments of the patellofemoral...

OBJECTIVES There is emerging evidence that knee alignment is associated with progression of osteoarthritis (OA). The aim of this study was to examine the relationship between baseline knee angle and the rate of cartilage loss in subjects with knee OA. METHODS One hundred and seventeen subjects with knee OA had standing radiographs and MRI on their symptomatic knee at baseline and at the 1.9+/...

Objectives: Sagittal plane tibial deformity has been implicated in anterior cruciate ligament ruptures, as most commonly quantified by measurement of the posterior slope (PTS) using lateral knee radiographs well full-length tibia radiographs. We propose a novel distance between superior aspect tubercle and plateau (Lateral SupraTubercle Distance (LSTD)) on This seems to have large variability b...

IntroductionLateral retinacular release, tibial tuberosity elevation, and tibial tuberosity elevation with medial transposition are commonly done at our institution in patients who have failed conservative therapy for patellofemoral pain syndrome. Our clinical results reflect the findings of multiple authors and are not always satisfactory. Usually, the retropatellar surface is referenced in bi...

Distal femoral varus osteotomy is a well-established procedure for the treatment of lateral compartment cartilage lesions and degenerative disease, correcting limb alignment and decreasing the progression of the pathology. Surgical techniques can be performed with a lateral opening-wedge or medial closing-wedge correction of the deformity. Fixation methods for lateral opening-wedge osteotomies ...

  Abstract   Background: The purpose of this study was to evaluate the significance of the Q   angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more   impression on TTTG).   Method: Atotal number of 68 knee joints of 50 cases entered the study.

BACKGROUND The authors report the long-term effect of acquired pseudoarthrosis of the fibula on ankle development in children during skeletal growth, and the results of a long-term follow-up of Langenskiold's supramalleolar synostosis to correct an ankle deformity induced by an acquired fibular segmental defect in children. METHODS Since 1980, 19 children with acquired pseudoarthrosis of the ...
