Pathologic genu recurvatum is defined by knee hyperextension in excess of 15 degrees and is usually asymmetric. This is a rare disease that can be related to bony, soft tissue or a combination of both. Patients with genu recurvatum commonly present with anterior knee pain, knee instability, ambulation difficulty on uneven ground, and patellofemoral instability. Anterior opening wedge osteotomy ...

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...

BACKGROUND According to the literature, closing and opening wedge high tibial valgus osteotomies can raise or lower the patella, and diffèrent methods of patella height measurement show similarly conflicting results. Clarification of this was thought to be important because there is much literature describing morbidity secondary to patella alta or patella infera (baja). Effects on tibial slope ...

PURPOSE To assess the prevalence of proximal high-origin anterior tibial artery and its surgical significance. METHODS 100 knees were prospectively studied using colour Doppler ultrasonography. No patient had a history of lower-limb arterial pathology or previous knee surgery. All ultrasound images were assessed by a single experienced vascular technician to eliminate inter-observer variabili...

 High tibial osteotomy (HTO) is a well established technique for the treatment of medial osteoarthritis ofthe knee with varus malalignment. The outcome of total knee arthroplasty (TKA) after HTO remains uncertain.The aim of this paper is to revise the literature with the aim of answering the following question: Does a previous (HTO)influence the long-term function or survival of a TKA?. The sea...

RATIONALE It is challenging to visualize and reduce a posterolateral tibial plateau fracture through an anterolateral approach as the tibial plateau fragments are often covered by the fibular head and ligamentous structures. PATIENT CONCERNS In this case report, we describe a patient with a depression fracture of the posterolateral quadrant combined with a split fracture of the posteromedial ...

BACKGROUND Tarsal tunnel syndrome is a known complication of lateralizing calcaneal osteotomy. A Malerba Z-type osteotomy may preserve more tarsal tunnel volume (TTV) and decrease risk of neurovascular injury. We investigated 2 effects on the tarsal tunnel of the Malerba osteotomy compared to a standard lateralizing osteotomy using a cadaveric model: (1) the effect on TTV as measured by magneti...

BACKGROUND This study examined the results of open wedge high tibial osteotomy with using an Aescula open wedge plate and an allogenic bone graft as a surgical technique for the patients who suffer from osteoarthritis of the knee with a genu varum deformity. METHODS From March 2007 to August 2007, 33 patients (37 cases) with osteoarthritis of the knee and a genu varum deformity underwent a hi...
