Patellofemoral instability is a common cause of anterior knee pain, especially in younger and more active patients. Treatment of instability varies considerably depending on the patient's symptoms as well as the cause of the instability. Lateral instability has a particularly broad spectrum of treatment algorithms including patellar taping, arthroscopy, lateral release, medial patellofemoral li...
Background: Posterior tibial slope (PTS) is an important factor in the knee joint biomechanics and one of the bone features, which leads to knee joint stability. Posterior tibial slope affects flexion gap, knee joint stability and posterior femoral rollback that are related to wide range of knee motion. During high tibial osteotomy and total knee arthroplasty (TKA) surgery, proper retaining the...
Fractures of the tibial tuberosity are infrequent injuries that occur during adolescence. Displaced tibial tuberosity fractures are typically treated with open reduction and internal fixation. Since these fractures occur at or near skeletal maturity, growth disturbances are not seen. This paper presents a case, the first report to our knowledge, of genu recurvatum deformity after open reduction...
BACKGROUND Postoperative regional anesthesia hastens recovery and reduces the length of hospital stay of orthopedic surgical patients. This study was designed to assess the impact of pre-incisional continuous femoral block on postoperative conditions (POC) of tibial osteotomy and total knee arthroplasty patients. METHODS After insertion of a femoral catheter under peripheral nerve stimulation...
Crouch gait deformity is common in children with cerebral palsy and often is associated with patella alta. Patellar tendon advancement typically is used to correct patella alta and restore normal knee mechanics. The purpose of this study was to determine the mechanical strength of surgical constructs used for fixation during patellar advancement procedures. This study used a cadaveric model to ...
PURPOSE To compare 2 methods of fixation for maintenance of alignment during healing of valgus tibial osteotomies. METHODS We performed a retrospective chart and radiographic review of valgus tibial osteotomy cases of staple fixation supplemented by a postoperative cast and of blade plate fixation for maintenance of femoral-tibial alignment during healing of the osteotomy. RESULTS Both grou...
The orthopaedic surgeon who performs opening-wedge high tibial osteotomy (HTO) has to be aware of the behavior slope depending on variations in location hinge and inclination osteotomy. most important point is that changing both rotation axis cut affects slope. There a natural trend unintentionally increase when performing an HTO. However, increased been established as risk factor for primary r...
BACKGROUND Anteromedialization of the tibial tuberosity has been shown to decrease mean total contact pressures of the lateral trochlea and to shift contact pressures to the medial trochlea. HYPOTHESIS Modifying the anteromedialization osteotomy to a straight anteriorization osteotomy of the tibial tuberosity can decrease trochlear contact pressures without a resultant medial shift of forces ...
Osteosclerosis of the subchondral bone was measured by densitometer on plain radiographs in 55 medial compartmental osteoarthritic knees of 40 patients who were treated with high tibial valgus osteotomy for correction of varus deformity. The ratio of the osteosclerosis value of the medial side of the knee to that of the lateral side (Medial/Lateral ratio) was calculated and used as a parameter....
Background: Varus knee is a common deformity of the joint, which usually accompanied by osteoarthritis, especially medial compartment. High tibial osteotomy good solution for varus transferring load from compartment to more healthy lateral slowing progression osteoarthritis. Objectives: To assess changes joint and ankle orientations after open wedge high osteotomy. Patients Methods: This pros...
