Symptoms include pain, swelling, and bruising to the front of the knee. [1] A person may also be unable to walk. [1] Complications may include injury to the tibia, femur, or knee ligaments. [2] It typically results from a hard blow to the front of the knee or falling on the knee. [1] The patella can also be fractured indirectly.
Damage to the saphenous nerve and its infrapatellar branch is possible during medial knee surgery, potentially causing numbness or pain over the medial knee and leg. [7] As with all surgeries, there is a risk of bleeding, wound problems, deep vein thrombosis , and infection that can complicate the outcome and rehabilitation process.
The patella (pl.: patellae or patellas), also known as the kneecap, is a flat, rounded triangular bone which articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint. The patella is found in many tetrapods, such as mice, cats, birds and dogs, but not in whales, or most reptiles.
The severity of the injury can vary from simple soft tissue damage to a knee joint fracture with neurovascular damage. The latter requires several weeks in hospital and intensive outpatient physiotherapy for recovery. [1] If the damage is too great, amputation may be necessary, [2] but this rarely occurs.
The upper part of the patellar tendon attaches on the lower part of the knee cap, and the lower part of the patella tendon attaches to the tibial tubercle on the front of the tibia. Above the knee cap, the quadriceps muscle via the quadriceps tendon attaches to the top of the knee cap. This structure allows the knee to flex and extend, allowing ...
There are two menisci in the knee. They sit between the thigh bone and the shin bone. While the ends of the thigh bone and the shin bone have a thin covering of soft hyaline cartilage, the menisci are made of tough fibrocartilage and conform to the surfaces of the bones they rest on. One meniscus rests on the medial tibial plateau; this is the ...
The Texans already lost Stefon Diggs to a season-ending knee injury. Dell had 569 yards and two touchdowns this season. He was having a big day Saturday against the Kansas City Chiefs with 98 ...
A patellar dislocation typically occurs when the knee is straight and the lower leg is bent outwards when twisting. [1] [2] Occasionally, it occurs when the knee is bent and the patella is struck directly. [1] Commonly associated sports include soccer, gymnastics, and ice hockey. [2] Dislocations nearly always occur away from the midline. [2]
