Historically, the patellofemoral articulation has been a topic of less interest among orthopaedists and has been subject to fewer studies when compared with other major joints in the body. Patellofemoral arthritis is a common and debilitating…

High tibial osteotomy is effective for managing a variety of knee conditions, including gonarthrosis with varus or valgus malalignment, osteochondritis dissecans, osteonecrosis, posterolateral instability, and chondral resurfacing. The fundamental…

BACKGROUND: We retrospectively reviewed 137 consecutive total hip arthroplasties performed with AML-A stems and Tri-Lock cups to see whether design modifications made to these components would achieve durable biological fixation in the Japanese…

Meniscal repair is a viable alternative to resection in many clinical situations. Repair techniques traditionally have utilized a variety of suture methods, including inside-out and outside-in techniques. Bioabsorbable implants permit all-inside…

Selecting the appropriate graft for ACL reconstruction depends on numerous factors including surgeon philosophy and experience, tissue availability (affected by anatomical anomalies or prior injury or surgery), and patient activity level and…
-
The patient with meniscal injury may present with pain, swelling, or mechanical symptoms and often requires surgical intervention for symptom resolution. Treatment of such injuries relies on understanding the gross and microanatomic features of the…

Unstable intertrochanteric hip fractures account for approximately one quarter of all hip fractures in the elderly and are increasing in frequency. Treatment goals include immediate mobilization while limiting complications. Preoperatively, medical…

Fractures of the talus are uncommon. The relative infrequency of these injuries in part accounts for the lack of useful and objective data to guide treatment. The integrity of the talus is critical to normal function of the ankle, subtalar, and…
-
Surgical approaches to the posterior aspect of the knee are not commonly needed, and their use has become even rarer with the increasing sophistication of arthroscopic technology. As a result, physicians in orthopaedic surgical training are not…

Ankle fractures are among the most common skeletal injuries; selection of an optimal management method depends on ankle stability. Stable fractures (eg, isolated lateral malleolar) generally are managed nonsurgically; unstable fractures (eg,…

The intramedullary nail or rod is commonly used for long-bone fracture fixation and has become the standard treatment of most long-bone diaphyseal and selected metaphyseal fractures. To best understand use of the intramedullary nail, a general…

Os acromiale, the joining of the acromion to the scapular spine by fibrocartilaginous tissue rather than bone, is an anatomic variant that has been reported in approximately 8% of the population worldwide. It is more common in blacks and males than…

Loss of meniscal cartilage leads to degenerative arthritis. Therefore, it is important to save the meniscus whenever possible. But not all damaged menisci can be treated by partial resection or repair. The concept of meniscal transplantation has…

Hip dysplasia is a developmental disorder that results in anatomic abnormalities leading to increased contact pressure in the joint and, eventually, coxarthrosis. However, many patients with hip dysplasia become symptomatic before the development of…

Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects the synovium in young and middle-aged adults. Although most believe that it is an inflammatory process, some believe that it is a benign neoplasm. The optimal…

Anterior knee pain is a frequent clinical problem. It provides a common challenge to diagnose and manage. Basic science studies have provided insight into the origin of anterior knee pain and refined understanding of the anatomy. Clinical evaluation…

Object The authors review a novel subaxial cervical trauma classification system and demonstrate its application through a series of cervical trauma cases. Methods The Spine Trauma Study Group collaborated to create the Subaxial Injury…

Total hip arthroplasty is the procedure of choice for most patients with symptomatic end-stage coxarthrosis secondary to hip dysplasia. The anatomic abnormalities associated with the dysplastic hip increase the complexity of hip arthroplasty. When…

Acute knee dislocations are uncommon orthopaedic injuries. Because they often spontaneously reduce before initial evaluation, the true incidence is unknown. Dislocation involves injury to multiple ligaments of the knee, resulting in multidirectional…
