A 24 year old otherwise healthy male was presented with a chief complaint of giving way in the left knee. MRI reportedcomplete anterior cruciate ligament (ACL) tearing. Arthroscopy showed ACL agenesis, ring-shaped lateral meniscus,and an anomalous thick band extending from the anterior horn of the lateral meniscus to the intercondylar notch of thelateral femoral condyle, which...

The menisco-femoral ligament is one of the most important accessory ligaments of the knee. It extends from the posterior horn of the lateral meniscus to the lateral aspect of the medial femoral condyle close to the femoral attachment of the posterior cruciate ligament. The accessory ligament may run behind or in front of the posterior cruciate ligament and is known either as the posterior menis...

Reconstruction of the posterolateral corner (PLC) of the knee is essential to restore knee joint function. Controversy exists regarding a standardized nomenclature, the connective attachments and the relationships between them, and the frequency of occurrence among all structures of the PLC. Thirty human cadaveric knee specimens were investigated. The lateral collateral ligament, popliteus tend...

Anatomical variations of the meniscus are a common anomaly that knee surgeons frequently encounter. However, anomalies of the anterior horn of the lateral meniscus (AHLM) are extremely rare. In this report, we present a newly discovered anomaly of the AHML: an anterolateral meniscofemoral ligament is described with clinical features and radiographic and arthroscopic findings.

A 58-year-old male patient who had developed left knee pain with a history of trauma was referred to our hospital. Physical examination and further examination by magnetic resonance imaging revealed results that closely resemble a horizontal tear of the lateral meniscus and a tear of the medial meniscus. Arthroscopically, we found a cord-like structure originating from the posterior 1/3 portion...

The purpose of this study was to evaluate prospectively the arthroscopic findings in the lateral compartment of knees with posterolateral knee complex injuries, to help identify individual injured anatomic structures, and to assist in the clinical identification of these injuries. Thirty of 33 consecutive knees noted to have grade 3 posterolateral knee complex injuries on preoperative evaluatio...

conclusions the clinical examination is an important and accurate diagnostic modality for evaluation of traumatic derangement of the knee joint. it is noninvasive, easy, available, and valuable diagnostic modality. the mri is an accurate diagnostic modality. it can be used whenever there is an uncertain indication for arthroscopy. however, costs have to be kept in mind, especially in patients w...

*The superficial medial collateral ligament and other medial knee stabilizers-i.e., the deep medial collateral ligament and the posterior oblique ligament-are the most commonly injured ligamentous structures of the knee. *The main structures of the medial aspect of the knee are the proximal and distal divisions of the superficial medial collateral ligament, the meniscofemoral and meniscotibial ...
