The aims to evaluate the effectiveness of dislocated and unstable knee joint reconstruction using calcanei combined with an Achilles tendon allograft using one-stage arthroscopy. From January 2008 to January 2010, we treated 11 patients with knee-joint dislocation using calcanei combined with an Achilles tendon allograft using one-stage arthroscopy. A total of 9 males and 2 females aged 17 year...

OBJECTIVE Muscles are essential components of our sensorimotor system that help maintain balance and perform a smooth gait, but it is unclear whether arthritic damage adversely affects muscle sensorimotor function. Quadriceps sensorimotor function in patients with knee osteoarthritis (OA) was investigated, and whether these changes were associated with impairment of functional performance. ME...

INTRODUCTION Fracture of the modern polyethylene insert of a total knee arthroplasty is rare. We describe the first case of a fractured anterior locking flange of the commonly used Depuy Press-fit Condylar (PFC) Sigma prosthesis. CASE REPORT The 80 year old Caucasian gentleman presented 8 years following previously uncomplicated and successful primary total knee replacement with pain, swellin...

BACKGROUND In the running community, a forefoot strike (FFS) pattern is increasingly preferred compared with a rearfoot strike (RFS) pattern. However, it has not been fully understood which strike pattern may better reduce adverse joint forces within the different joints of the lower extremity. PURPOSE To analyze the 3-dimensional (3D) stress pattern in the ankle, knee, and hip joint in runne...

A 6-yr-old boy was the victim of a burns accident in a public bathhouse. The burns involved the face, neck, upper and lower extremities, anterior and posterior trunk, and both buttocks, covering 72% of the total body surface area (TBSA). The lesions in the lower extremities and parts of the right upper extremity were deep partial-thickness, comprising 40% TBSA. On day 5 post-burn, the lesions i...

OBJECTIVES Determine the stability of tibial and femoral components of 20 cementless knee arthroplasties with rotating platform. METHODS The 20 patients (20 knees) underwent an analysis of dynamic radiographs with an image amplifier and maneuvers of varus and valgus which were compared to static frontal and lateral radiographs of the knees and analyzed by two experienced surgeons in a double-...

Revision total knee surgery has evolved through ened with time such that, at the time of revision the decade of the 1990s so that it has a pretotal knee replacement, equalization of the dictable outcome if certain principles are obextension and flexion gap or mediolateral staserved. These principles include the underbility is not possible or is so compromised that standing of the loss of biolog...

If the knee becomes unstable after a ligamentous injury, permanent problems may result, especially if the patient is an athlete with high functional demand. If the history indicates that there is possibly instability, an examination to detect the exact location and degree of this is performed. It is important to make this supplementary examination only when symptoms and signs found in the routi...
