conclusions in this case series study, the fixation of different types of tibial plateau fractures with 3.5 mm simple non-locking and non-precontoured plates was associated with acceptable clinical, functional, and radiographic outcomes. based on the advantages and costs of these plates, the authors recommend using 3.5 mm simple plates for different types of tibial plateau fractures. results th...

OBJECTIVES To determine whether articular cartilage defects are associated with cartilage loss and joint replacement in subjects with symptomatic knee osteoarthritis (OA). METHODS One hundred and seventeen subjects with symptomatic knee OA underwent magnetic resonance imaging of their dominant knee at baseline and 2 yr later. Cartilage defects were identified as prevalent (defect score > or =...

BACKGROUND We report intra- and postoperative complications of unicompartmental knee arthroplasty (UKA). METHODS This study was conducted on 246 cases of UKA which were performed for degenerative osteoarthritis confined to the medial compartment, from May 2002 to May 2010, for which follow-up periods longer than one year were available. Complications were divided into intra- and postoperative...

PURPOSE To review records of 17 patients who sustained a tibial or femoral intra-operative fracture during primary cemented total knee arthroplasty (TKA) METHODS. Records of 1346 primary cemented TKAs using the NexGen LPS fluted tibial component performed by a single surgeon were reviewed. 12 tibial and 5 femoral intra-operative fractures occurred in 5 men and 12 women aged 54 to 83 (mean, 71.6...

High tibial osteotomy (HTO) is a surgical procedure to re-align varus or valgus mal-alignment of the knee. Medial opening wedge HTO is a surgical treatment of choice for knee varus mal-alignment with many advantages over lateral closing wedge HTO. However, the opening of the medial wedge alters the plane of the lateral tibial plateau, especially when the correction angle is large, which may be ...

Purpose: high tibial osteotomy (HTO) is a recommended treatment for medial compartment knee osteoarthritis. Newer cartilage regenerative procedures may add benefits to the result of HTO. In this prospective study we investigate safety and also results of HTO associated with bone marrow derived cells (BMDC) transplantation in relatively young and middle aged active individuals with early osteoar...

INTRODUCTION: Abnormal medial loading results in decreased cartilage thickness, osteophyte ingrowths, and subchondral bone sclerosis of the medial femoral and tibial condyles in patients with medial knee osteoarthritis (OA). Among these changes, subchondral bone sclerosis may reflect altered mechanical loading. However, sclerosis of the knee condyles remains difficult to visually discern on rad...

Despite general agreement on the effects of knee valgus and internal tibial rotation on anterior cruciate ligament (ACL) loading, compelling debate persists on the interrelationship between these rotations and how they contribute to the multi-planar ACL injury mechanism. This study investigates coupling between knee valgus and internal tibial rotation and their effects on ACL strain as a quanti...
