congenital dislocation of the knee (cdk) is a rare disorder. we report the case of a 7-year-old girl with bilateral knee stiffness, marked anterior bowing of both legs, and inability to walk without aid. radiologic investigation revealed bilateral knee joint dislocation accompanied by severe anterior bowing of both tibia proximally and posterior bowing of both femur distally, demonstrating a co...

We reviewed 20 patients who had undergone one-stage (7 cases) or two-stage (13 cases) knee arthrodesis using the Vari-Wall intramedullary nail, as a salvage operation following infection of a total knee arthroplasty. The procedure was followed by systemic antibiotic administration and early rehabilitation. Intraoperative microbiological cultures were taken. The average period of follow-up was 2...

We report on a 41-year-old man with multiple epithelioid hemangioendothelioma of the left foot and ankle. The patient was treated with curettage and fixation with 2 separate plates, but later developed local infection. Owing to the potential for malignancy, below-knee amputation was suggested, but the patient declined and was treated symptomatically with close monitoring. The patient underwent ...

Total ankle arthroplasty was developed to reduce pain and retain motion of the ankle joint in patients with osteoarthritis much like its total hip and knee counterparts. Orthopaedic surgeons are well equipped to evaluate and treat patients with end-stage hip or knee arthritis; however, the management of patients with ankle arthritis represents a challenge to both general orthopaedic surgeons an...

Inertial sensors have gained relevance as wearable to acquire the kinematics of human limbs through fusion sensor algorithms and biomechanical models. However, there are some limitations use Measurement Units in control robotic devices: 1) Some approaches magnetometer readings estimate orientation sensor, and, a result, they prone errors due electromagnetic interferences; 2) Biomechanical model...

multiplanar or global laxity in arthritic knee is rare , most of this patients have neuromuscular disorder (post poliomyelitis , spinal dystrophy) or history of knee trauma. ligament insufficiency and severe bone loss is significant in this patient. the estimated prevalence for the concurrence of charcot marie-tooth (cmt) with myasthenia gravis (mg) suggests an extremely rare event. we have pre...

background: the aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3d reconstructive ct scan imaging. methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. preoperatively, all the patients underwent a ct scan according to a standard prot...

Aneurysmal bone cysts (ABCs) are benign, expansible, nonneoplastic lesions of the bone, characterized by channels of blood and spaces separated by fibrous septa, which occur in young patients and, occasionally, with aggressive behavior. Giant ABC is an uncommon pathological lesion and can be challenging because of the destructive effect of the cyst on the bones and the pressure on the nearby st...

Autologous platelet-rich plasma (PRP) therapies have seen a dramatic increase in breadth and frequency of use for orthopaedic conditions in the past 5 years. Rich in many growth factors that have important implications in healing, PRP can potentially regenerate tissue via multiple mechanisms. Proposed clinical and surgical applications include spinal fusion, chondropathy, knee osteoarthritis, t...
