People who have been engaged in heavy physical labor and violent bouncing for a long time are likely to hurt their knees. The main symptoms are synovitis, cruciate ligament tear, meniscus injury and cartilage injury.
People whose knees are often stimulated by cold are prone to chronic knee diseases, such as pigmented villonodular synovitis and chronic synovitis. These diseases are intractable diseases in clinic, and there is no specific medicine, so they can only be treated by surgery.
Extended data:
Knee joint is composed of medial and lateral condyle of femur, medial and lateral condyle of tibia and patella. It is the largest joint in human body, with the most complicated structure and more chances of injury.
The joint capsule is thin and loose and attached to the periphery of each articular cartilage. Ligaments around the joint capsule are strengthened. Anterior patellar ligament is the continuation of quadriceps femoris tendon (patella is the seed bone in this tendon), which extends from the lower end of patella to tibial tubercle. There are medial and lateral patellar retinaculum on both sides of patellar ligament, which is formed by the downward extension of medial femoral muscle and lateral femoral aponeurosis and interweaving with knee joint capsule.
The posterior oblique ligament of popliteal muscle is strengthened, which is formed by the tendon fibers of semimembranous muscle woven into the joint capsule; There is a tibial collateral ligament in the medial side, which is flat and banded, starting from the adductor tubercle and spreading downwards, and interweaving in the fibrous layer of the joint capsule; The lateral collateral ligament of fibula is an annular fiber bundle independent of the joint capsule, which starts from the lateral epicondyle of femur and ends at the fibular capitulum.
