Push patellar resistance pain

Introduction Pushing and resisting pain: It is also positive. The tibia is pushed distally and the quadriceps contraction is positive. One of the signs of patellofemoral articular cartilage injury. Pushing and resisting pain is a kind of articular cartilage damage. Generally speaking, any mechanism that affects the normal secretion of joint synovium or articular cartilage can be caused. When the patient is active, he complains of soreness after sputum, and the symptoms such as aggravation of pain when going upstairs or half a squat, combined with signs such as sacral tenderness, sputum sputum, single leg and half sputum pain, and periorbital tenderness can be roughly diagnosed as the disease. .

Cause

Reasons for pushing back the resistance to pain: Any mechanism that affects the normal secretion of the synovial membrane or the articular cartilage extrusion mechanism, which hinders the normal movement of the joint, can cause damage to the articular cartilage.

Excavation and anti-obstruction examination and diagnosis:

1. Clinical features: When the patient is active, complaining of soreness after sputum, symptoms such as aggravation of pain when going upstairs or half a squat, combined with physical signs, such as tenderness of the tibia, sputum, sputum, sputum, sputum, and so on. A rough diagnosis is the disease.

2. Imaging examination

(1) X-ray seeing: taking ordinary X-ray film does not make much sense for diagnosis. However, if you choose to take the axial position of the humerus at different knee angles, you can observe the shape of the tibia, the degree of hardening of the subchondral bone, and measure some indexes of the tibia, such as the humerus angle, the tibia depth index, the tibia index, the groove angle, the overlap angle, etc. . Lateral knee radiographs can detect abnormal position of the humerus. Normally, the length of the tibia (P) is equal to the length of the patellofemoral ligament (PT). When the PT exceeds 15% of P or exceeds 1 cm, it is a high tibia.

(2) MRI examination: exfoliation and ulceration of the tibial cartilage can be found.

3. The final diagnosis basis: the diagnosis must rely on arthroscopy, surgical exploration or MR examination.

Differential diagnosis

Identification of anti-obstructive pain:

Tibial pain: In the early stage of the tibia femoral pain syndrome, the knees may experience pain when walking, going up and down the stairs, and standing up under the armpits. In severe cases, there may be sudden knees unable to force or even stand unstable during walking.

Tibial fissure: The humerus is the largest sesamoid in the human body and an integral part of the knee joint. The humeral fissure is medically known as a crack fracture and is one of the types of humeral fractures.
