The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement.It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch [5] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
Grade III, the PCL is torn completely and the knee can now be categorized as unstable. Grade IV, the ligament is damaged along with another ligament housed in the knee (i.e. ACL). With these grades of PCL injuries, there are different treatments available for such injuries. [citation needed] The posterior cruciate ligament is located within the ...
If the anterior movement of the affected knee is greater than the unaffected knee, then the anterior drawer test is positive. The Lachman test is more sensitive than the anterior drawer test. For the Lachman test, the person lies down in supine position with the knee flexed at 20 degrees and the heel touching the bed. The tibia is then pulled ...
The knee joint contains two crescent-shaped fibrocartilaginous structures, the menisci (medial and lateral), which serve as shock absorbers and stabilize the joint during movement. Each meniscus has an outer vascular zone (red-red zone), which has a good blood supply and healing potential as well as a central avascular zone (white-white zone ...
A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
Nearly 41% of knee dislocations have an associated fracture, with the majority of these fractures in one of the legs. [46] Nerve injury occurs in about 15.3% of knee dislocations, while major artery injury occurs in 7.8% of knee dislocations. [46] More than half (53.5%) of knee dislocations have an associated torn meniscus. [46]
Knee pain is pain caused by wear and tear, such as osteoarthritis or a meniscal tear. Effective treatments for knee pain include physical therapy exercises, [ 28 ] pain-reducing drugs such as ibuprofen , joint stretching, [ 29 ] [ 30 ] knee replacement surgery, and weight loss in people who are overweight.
To assess the knee, a clinician can perform the Patellar Aprehension Test by moving the patella back and forth while the people flexes the knee at approximately 30 degrees. [ 14 ] The people can do the patella tracking assessment by making a single leg squat and standing, or by lying on his or her back with knee extended from flexed position.
