A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body ...
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 attachment is at ...
The medial collateral ligament (MCL), also called the superficial medial collateral ligament (sMCL) or tibial collateral ligament (TCL), [1] is one of the major ligaments of the knee. It is on the medial (inner) side of the knee joint and occurs in humans and other primates. Its primary function is to resist valgus (inward bending) forces on ...
An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. [ 1 ] The most common injury is a complete tear. [ 1 ] Symptoms include pain, an audible cracking sound during injury, instability of the knee, and joint swelling. [ 1 ]
The posterior cruciate ligament is located within the knee. Ligaments are sturdy bands of tissues that connect bones. Similar to the anterior cruciate ligament, the PCL connects the femur to the tibia. There are four different grades of classification in which medical doctor's classify a PCL injury: Grade I, the PCL has a slight tear.
A difference of greater than 10-15° indicates a positive test and likely injuries to the posterolateral knee. Next, repeat the test with the patient's knees flexed at 90°. Increased rotation at 90° indicates a combined PCL and posterolateral knee injury. If the rotation decreases compared to 30°, then an isolated PLC injury has occurred.
Human knee. Specialty. Orthopedics. Knee pain is pain in or around the knee. The knee joint consists of an articulation between four bones: the femur, tibia, fibula and patella. There are four compartments to the knee. These are the medial and lateral tibiofemoral compartments, the patellofemoral compartment and the superior tibiofibular joint.
