Patellar ligament injury symptoms?

summary

Patellar ligament, the extension of quadriceps femoris tendon, is one of the most powerful ligaments in the whole body, located in front of the knee joint capsule. The patellar ligament starts from the patellar tip and the rough surface behind it, and ends at the tibial tubercle, about 8 cm long. The middle part of the patellar ligament is the joint plane. There are medial and lateral retinaculum on both sides of the patellar ligament from the medial and lateral femoral muscles to strengthen the joint capsule and prevent lateral dislocation of the patella. Patellar ligament injury symptoms? Let's talk about it

Patellar ligament injury symptoms?

Ligament rupture: in general, it is because of the action beyond the range of joint activity, which leads to the tear or complete rupture of the related ligament due to passive traction. Ligament rupture is often accompanied by sprain and fracture.

Ligament sprain: ligament sprain refers to the injury of soft tissues (such as muscles, tendons, ligaments, blood vessels, etc.) in the joints or body parts of the limbs, without fracture, dislocation, skin damage, etc. The main clinical manifestations were pain and swelling in the injured area and limited joint movement, which mostly occurred in waist, ankle, knee, shoulder, wrist, elbow and hip.

After ligament injury, there are usually small blood vessels rupture and bleeding, local pain, swelling, bleeding, hematoma, joint swelling, movement disorders, tenderness.

matters needing attention

Strengthen functional exercise: strengthen lumbar and abdominal muscle exercise, to enhance muscle elasticity and endurance, improve the stability, flexibility and durability of the spine, improve the state of muscle oxygen supply, release adhesion, are beneficial. On the contrary, too much bed rest is not appropriate. The principle of functional exercise is to carry out muscle static contraction exercise without causing pain and muscle spasm. The functional exercise method of low back pain is supine, arms extended backward, head and neck lifted as far as possible, so that the chest away from the bed.
