REVIEW

OBJECTIVE: The purpose of this article is to show the important radiographic criteria that indicate the two types of femoroacetabular impingement: pincer and cam impingement. In addition, potential pitfalls in pelvic imaging concerning femoroacetabular impingement are shown. CONCLUSION: Femoroacetabular impingement is a major cause for early "primary" osteoarthritis of the hip. It can easily be recognized on conventional radiographs of the pelvis and the proximal femur...

Arthroscopy-based semiquantitative scoring systems such as Outerbridge and Noyes' scores were the first to be developed for the purpose of grading cartilage defects. As magnetic resonance imaging (MRI) became available for evaluation of the osteoarthritic knee joint, these systems were adapted for use with MRI. Later on, grading methods such as the Whole Organ Magnetic Resonance Score, the Boston-Leeds Osteoarthritis Knee Score and the MRI Osteoarthritis Knee Score were designed specifically for performing whole-organ assessment of the knee joint structures, including cartilage...

In the presence of joint space narrowing, it is important to differentiate inflammatory from degenerative conditions. The presence of osteophytes, bone sclerosis, and subchondral cysts and the absence of inflammatory features such as erosions suggest osteoarthritis. Typical osteoarthritis involves specific joints at a particular patient age. When osteoarthritis involves an atypical joint, occurs at an early age, or has an unusual radiographic appearance, then other causes for cartilage destruction should be considered, such as trauma, crystal deposition, neuropathic joint, and hemophilia...

#4
REVIEW
Sameer Dixit, John P DiFiori, Monique Burton, Brandon Mines
Patellofemoral pain syndrome (PFPS) is the most common cause of knee pain in the outpatient setting. It is caused by imbalances in the forces controlling patellar tracking during knee flexion and extension, particularly with overloading of the joint. Risk factors include overuse, trauma, muscle dysfunction, tight lateral restraints, patellar hypermobility, and poor quadriceps flexibility. Typical symptoms include pain behind or around the patella that is increased with running and activities that involve knee flexion...

REVIEW

In the presence of joint space narrowing, it is important to differentiate inflammatory from degenerative conditions. Joint inflammation is characterized by bone erosions, osteopenia, soft-tissue swelling, and uniform joint space loss. Inflammation of a single joint should raise concern for infection. Multiple joint inflammation in a proximal distribution in the hands or feet without bone proliferation suggests rheumatoid arthritis. Multiple joint inflammation in a distal distribution in the hands or feet with bone proliferation suggests a seronegative spondyloarthropathy, such as psoriatic arthritis, reactive arthritis, or ankylosing spondylitis...

Arthur A De Smet
OBJECTIVE: The goal of this article is to summarize the literature about the diagnosis of meniscal tears on MRI including the normal appearance of the meniscus and the appearance of the various types of meniscal tears. In addition, I discuss my experience with the causes of errors in the MR diagnosis of meniscal abnormalities and the nuances of meniscal abnormalities that can mimic a meniscal tear. CONCLUSION: MRI is a highly accurate imaging method for diagnosing meniscal tears...

REVIEW
James M Linklater
OBJECTIVE: This article selectively reviews several areas in which imaging can play a major role in the diagnosis and treatment of sports injuries of the foot. CONCLUSION: Diagnostic imaging provides useful evaluation of capsuloligamentous sports injuries and Morton neuroma in the foot and facilitates appropriate treatment. An understanding of the relevant anatomy, normal imaging appearance, and the spectrum of imaging findings in the setting of injury is important for the practicing radiologist...

#8
T Kumazaki, Y Ehara, T Sakai
The hamstring muscles were analyzed anatomically and physiologically to clarify the specific reasons for the incidence of muscle strain of the hamstrings. For the anatomical study, hamstring muscles of 13 embalmed cadavers were dissected. For the physiological study, the knee flexor torque and surface electromyographic (EMG) signals were measured during isometric contraction of hamstring muscles in 10 healthy adults. The biceps femoris muscle long head (BF-L) and semimembranosus muscle (SM) had hemi-pennate architecture and their fiber length per total muscle length (FL/TML) was smaller than that of semtendinosus muscle (ST) and biceps femoris muscle short head (BF-S) with other architecture...
