We report for the first time the abnormal increases in posterior subluxation of the medial and lateral tibial plateaus after sectioning the posterolateral structures and posterior cruciate ligament. We applied specific forces and moments to the knees of seven cadaveric whole lower limbs and measured the position of the tibia at which the ligaments and the geometry of the joint limited motion. R...

Patients with tibial pilon fractures have a higher incidence of post-traumatic osteoarthritis than those with fractures of the tibial plateau. This may indicate that pilon fractures present a greater mechanical insult to the joint than do plateau fractures. We tested the hypothesis that fracture energy and articular fracture edge length, two independent indicators of severity, are higher in...

BACKGROUND Osteochondritis dissecans are typically located mainly on the femoral condyle, with reported but less common cases of patella involvement. In this case report, we reported a rare case of osteochondritis dissecans located on the medial tibial plateau. CASE PRESENTATION A 26-year-old Han Chinese woman presented with a lesion on her left medial tibial plateau. She was treated by arthr...

Like other intra-articular fractures, the tibial plateau fracture is challenging for orthopedic surgeons because of its severity of trauma, associated soft tissue injuries. Open reduction incurs serious complications, especially wound healing after traditional dissections. Unsatisfactory results often occur in complex or bicondylar tibial plateau fractures. Traditional surgical methods achieved...

OBJECTIVES Meniscal extrusion is often present in knees with OA, and has been associated with cartilage changes. It is unknown whether meniscal extrusion is related to subchondral bone. The aim of the study was to examine the relationship between meniscal extrusion and knee cartilage and subchondral bone, and also changes in these structures over 2 years in a cohort with mild to moderate knee O...

BACKGROUND The objective of this study was to investigate the biomechanical and histological effects of the posterior cruciate ligament (PCL) on the medial tibial plateau. METHODS A total of 12 cadaveric human knee specimens were collected and grouped as follows: the PCL intact group (n = 12), the anterolateral bundle rupture group (n = 6), the postmedial bundle rupture group (n = 6), and the...

INTRODUCTION High energy tibial plateau fractures along with calcaneal fractures individually produce several challenges for the orthopaedic surgeon. The principles of bony reconstruction include anatomic reduction and rigid internal fixation of intra-articular fractures and accurate restoration of the coronal, sagittal and transverse mechanical axes. Due to the tenuous nature of the soft tissu...

Tibial plateau fractures require appropriate treatment and rehabilitation to obtain a stable, pain-free and mobile joint (1). The variables like extensor lag, condition of the articular cartilage, range of motion, instability, axial malalignment, and articular incongruity have been reported to determine the functional outcome in tibial plateau fractures (2-8) .A number of treatment modalities i...

background fractures of the knee account for about 6% of all trauma admissions. while its management is mostly focused on fracture treatment, it is not the only factor that defines the final outcome. objectives this study aimed to study objective and subjective outcomes after proximal tibial versus distal femoral fractures in terms of knee instability and health-related quality of life. patient...

Study Design: Prospective consecutive series. Objective: To evaluate the functional outcome of Surgical management of Tibial Plateau Fractures. Summary of Background data: Earlier there was great reluctance towards operative management of these fractures because of lack of proper implants and adequate fixation techniques. But now due to the better understanding of biomechanics of knee joint, ty...
