Proximal hamstring tears are among the most common sports-related injuries and are frequently seen during eccentric muscle contractions, forced hip hyperflexion, and ipsilateral knee extension and fall accidents.1,2 The hamstring muscle group consists of 3 posterior thigh muscles, including the semimembranosus, semitendinosus, and the biceps femoris muscles. The […]
Knee ligament injuries are common, and treatment methods are continually evolving. Accurate clinical diagnosis with imaging confirmation is critical to support appropriate treatment. Several imaging pearls allow for improved recognition of injuries. Stress radiographs may be obtained to […]
The fabella is a sesamoid bone located in the posterolateral aspect of the knee, embedded in the muscular and tendon fibers of the lateral head of the gastrocnemius muscle. It articulates anteriorly with the posterior surface of the lateral condyle, and is bordered posteriorly by the oblique […]
Radiographic identification of the anatomic attachment sites of knee ligament structures allows surgeons to obtain an accurate diagnosis and treatment of knee injuries. The previous studies have provided quantitative and radiographic data for other ligaments, which has aided surgeons in intraoperative tunnel placement and postoperative assessment of […]
Over the past decade, there has been an increasing emphasis on anatomic anterior cruciate ligament (ACL) reconstruction to best restore knee kinematics after an ACL tear. Although studies have shown that the position, size and shape of the ACL insertion site are variable, anatomic single-and double-bundle ACL reconstructions […]
Meniscal repair procedures are increasingly performed because of an enhanced understanding of the long-term deleterious consequences of meniscectomy, the benefits of meniscal preservation, and the improved techniques and devices available for meniscal repair. While meniscal repair has demonstrated a higher reoperation rate than meniscectomy, recent studies have reported […]
The anterior cruciate ligament (ACL) is one of the most studied structures of the human musculoskeletal system, being the subject of many anatomic and biomechanical studies. While treatment options for complete ruptures of the ACL are well studied, partial ACL tears remain more nebulous in their postinjury treatment course. Partial ACL tears were first described […]
Background: Outcomes after transtibial pull-out repair for posterior meniscal root tears remain underreported, and factors that may affect outcomes are unknown.
Purpose/Hypothesis: The purpose of this study was to compare patient-centered outcomes after transtibial pull-out repair for posterior root tears in patients \50 and 50 years of age. We […]
The posterior cruciate ligament (PCL) is recognized to be the main posterior stabilizer of the knee. PCL injuries are most commonly associated with concurrent ligament injuries and also with a high prevalence of chondral and meniscal injuries. Recent evidence of the accuracy of the stress radiographs as […]
Purpose:
To retrospectively determine if a modified clinical magnetic resonance (MR) imaging protocol provides information on the origin of juvenile osteochondritis dissecans (JOCD) lesions and allows for staging on the basis of the proposed natural history of JOCD to better guide clinical management of the disease.
Materials and Methods:
This institutional review board–approved, HIPAA-com- pliant, retrospective […]
