In birds, where the arm is somewhat rotated compared to other tetrapods, it is termed dorsal epicondyle of the humerus. In comparative anatomy, the term ectepicondyle is sometimes used. [2] A common injury associated with the lateral epicondyle of the humerus is lateral epicondylitis also known as tennis elbow. Repetitive overuse of the forearm ...

The oblique popliteal ligament (posterior ligament) is a broad, flat, fibrous ligament on the posterior knee. [1] It is an extension of the tendon of the semimembranosus muscle. [1] [2] It attaches onto the intercondylar fossa and lateral condyle of the femur. [2] It reinforces the posterior central portion of the knee joint capsule. [3]
The anterolateral ligament (ALL) is a ligament on the lateral aspect of the human knee, anterior to the fibular collateral ligament. [1]Perhaps the earliest account of the ALL was written by French surgeon Paul Segond in 1879, in which he described a ligamentous structure between the lateral femur and tibia.
The lateral collateral ligament (LCL, long external lateral ligament or fibular collateral ligament) is an extrinsic ligament of the knee located on the lateral side of the knee. [ 1 ] [ verification needed ] [ 2 ] Its superior attachment is at the lateral epicondyle of the femur (superoposterior to the popliteal groove); its inferior ...
The mechanism of injury, location, character of the knee pain, the presence of a "pop" sound at the time of the injury (indicates ligamentous tear or fracture), swelling, infections, ability to stand or walk, sensation of instability (suggestive of subluxation), or any previous traumatic injuries to the joint are all important historical features.
Therefore, lateral femoral condyle acts as an axis for medial femoral condyle to rotate backwards. This movement is aided by the oblique pull of the ligaments of the knee joint and contraction of the quadriceps muscles. The ligaments are pulled taut when the knee joint is locked in place during standing.
Originally described by Dr. Paul Segond in 1879 [6] [7] after a series of cadaveric experiments, the Segond fracture occurs in association with tears of the anterior cruciate ligament (ACL) (75–100%) and injury to the medial meniscus (66–75%), lateral capsular ligament (now known as the Anterolateral ligament, or ALL), as well as injury to the structures behind the knee.
