The purpose of this study was to conduct a prospective outcome analysis of proximal tibial opening wedge osteotomies performed in young and middle-aged patients (aged < 55 years) for the treatment of symptomatic medial compartment osteoarthritis of the knee.
Current methods of the transtibial pull-out meniscal root repair significantly displace under cyclic loading in porcine models but have not been evaluated in human models. One potential explanation for the displacement is that a single transtibial tunnel may not fully restore the attachment of the entire posterior medial meniscal root.

Three patients were seen for pain and snapping over the lateral aspect of their symptomatic knee during deep knee flexion. On physical examination, each patient had subluxation of the long head of the biceps over the lateral aspect of the fibular head. Each patient underwent an anatomic repair of the torn anterior arms of […]
There has recently been increased interest in the use of 7.0-T magnetic resonance imaging for evaluating articular cartilage degeneration and quantifying the progression of osteoarthritis.
It is often difficult to identify the attachment sites of the fibular collateral ligament, popliteus tendon, and popliteofibular ligament for chronic posterolateral knee injuries or during revision surgeries. Descriptions of radiographic landmarks for these attachment sites would assist in the intraoperative identification of their locations and also allow for postoperative assessment of the placement […]
Intramedullary (IM) nailing is the treatment of choice among orthopaedic surgeons for tibial shaft fractures. However, because of the close proximity of the nail’s insertion site to the anterior medial (AM) meniscal root on the tibial plateau, there is increased risk of iatrogenic injury to the meniscal root during nailing. The purpose of this […]
A detailed understanding of the anatomy and biomechanics of the lateral knee is essential for the clinical diagnosis and surgical treatment of lateral-sided knee injuries. In the past, the structure and function of the lateral and posterolateral knee was poorly understood and was dubbed by some as “the dark side of […]
When surgical intervention is required for a grade 3 superficial medial collateral ligament (sMCL) tear, there is no consensus on the optimal surgical treatment. Anatomic augmented repairs and anatomic reconstructions for treatment of grade 3 sMCL tears have not been biomechanically validated or compared. This study hypothesized that anatomic sMCL augmented repairs and anatomic […]
The clinical diagnosis of impingement is the most common diagnostic label for shoulder pain. However, the diagnosis is so broadly applied that different tissue pathologies and various and often conflicting pathomechanics may contribute to the pain. The objective in part two of this study is to compare differences […]
Prior studies have suggested that anatomic double-bundle (DB) posterior cruciate ligament reconstruction (PCLR) reduces residual laxity compared with the intact state better than single-bundle PCLR. Although the anterolateral bundle (ALB) and posteromedial bundle (PMB) reportedly act codominantly, few studies have compared commonly used graft fixation angles and the influence that graft fixation angles have […]
