OBJECTIVE To evaluate the effect of tibial plateau leveling on joint motion in canine stifle joints in which the cranial cruciate ligament (CCL) had been severed. STUDY DESIGN In vitro cadaver study. ANIMALS Six canine cadaver hind legs. METHODS Radiographs of the stifle joints were made to evaluate the tibial plateau angle with respect to the long axis of the tibia. The specimens were mo...

BACKGROUND Tibial fracture is the third most common long-bone fracture in children. Traditionally, most tibial fractures in children have been treated non-operatively, but there are no long-term results. METHODS 94 children (64 boys) were treated for a tibial fracture in Aurora City Hospital during the period 1980-89 but 20 could not be included in the study. 58 of the remaining 74 patients r...

abstract the leg is a complex district with functions of weightbearing support, stability, and motility. the management of extensive and complex defects is more challenging and often results in leg amputation or shortening. leg amputation is a severe mutilation that alters the patient’s work and social life by limiting ambulation and self-sufficiency. during a 3 years period we treated four pat...

BACKGROUND The purpose of this study was to quantify the meniscal root anatomy of the New Zealand white rabbit to better understand this animal model for future in vitro and in vivo joint degeneration studies. METHODS Ten non-paired fresh frozen New Zealand white rabbit knee stifle joints were carefully disarticulated for this study. Measurements were made for all bony landmarks and ligamento...

Accurate modeling of the high strain-rate response of healthy human knee cartilage is critical to investigating the mechanism(s) of knee osteoarthritis and other cartilage disorders. Osteoarthritis has been suggested to originate from regional shifts in joint loading during walking and other high strain-rate physical activities. Tibial plateau cartilage under compression rates analogous to walk...

To describe the differences in knee structure and non-knee structural factors between offspring having at least one parent with a total knee replacement for severe primary knee osteoarthritis and age- and sex-matched controls with no family history of knee osteoarthritis, a population-based longitudinal study of 163 matched pairs (mean age 45 years, range 26 to 61) was performed at baseline and...

INTRODUCTION Several cases of tibial post breakage are reported in the literature. To the best of our knowledge, only three cases of NexGen knee prosthesis (Zimmer, Warsaw, Indiana, USA) tibial post failure have been reported. CASE PRESENTATION In November 1999, a 63-year-old Caucasian woman from Italy with a history of symptomatic left knee osteoarthritis underwent a total knee arthroplasty....

BACKGROUND Fracture of the proximal tibial metaphysis in children is a rare injury but notorious for carrying the risk of subsequent valgus deformity of the tibia. HYPOTHESIS Trampoline-caused fracture of the proximal tibial metaphysis in children may not progress into valgus. MATERIALS AND METHODS We followed up six children who collectively sustained seven fractures of the proximal tibial...

Tibia is the most commonly fractured long bone in the body with an annual incidence of tibial shaft fractures 2 per 1000 individuals. The use of non-operative treatment of tibial fractures that are widely displaced or that are the result of high-energy forces is associated with a high prevalence of malunion, stiffness of the joint, and poor functional outcome. Closed Tibial diaphyseal fractures...

BACKGROUND After anterior cruciate ligament (ACL) reconstruction, formation of cortical sclerotic bone encircling the femoral and tibial tunnel is a part of intratunnel graft healing. During the physiological cascades of soft tissue healing and bone growth, cellular and hormonal factors play an important role. The purpose of this study was to non-invasively but quantitatively assess the effect ...
