Introduction

Introduction The humeral knee pain syndrome is a specialized vocabulary that describes the pain that occurs in front of or around the tibia. Patellaofemoral Pain Syndrome, also known as anterior knee pain, is caused by abnormal movement of the femur during flexion. A common cause is damage to the tibia of the tibia, which is caused by the impact force on the tibia of the tibia. This injury is also called the patellar ligament pain syndrome or the running knee.

Cause

Cause

A common cause is damage to the tibia of the tibia, which is caused by the impact force on the tibia of the tibia. This injury is also called the patellar ligament pain syndrome or the running knee.

1. Excessive load - When the knee is flexed, the pressure on the tibia and femur is increased. Like running, repeated overweight training leads to excessive pressure on the knee joint, and the patella knee pain syndrome occurs.

2. Muscle imbalance - the quadriceps are responsible for the straightening of the knee joint. If the muscles on the outside are more tense than the muscles measured, or vice versa, it is easy to cause an abnormality in the trajectory of the tibia to increase the pressure of the tibia.

3. K-angle changes in the knee - some people have a larger Q angle than normal people. In this state, excessive load causes excessive pressure on the knee joint, resulting in damage to the cartilage structure under the knee joint. pain.

4. During the instep back training, the extreme flexion of the instep causes the pressure between the tibia and femur to cause damage.

Pain in front of the knee, especially near the patellar ligament.

When the knee is flexed, there is pain in the knee.

A sensitive area appears at the edge of the tibia. There is often swelling of the knee.

Pain when going upstairs when standing up or downhill.

The sound of grinding occurs when the knee joint is flexed, and the knee joint is uncomfortable after a long sitting posture.

Other symptoms of the patella knee pain syndrome: temporary loss of function.

Atrophy of the quadric muscles, especially the muscle atrophy of the intra-femoral probe.

The increase in the Q angle of the knee exceeds 18 to 20 degrees.

The calf, quadriceps, and muscles of the posterior group are tightened.

Diagnosis

Differential diagnosis

Unstable patella is a common cause of anterior knee pain and is a common disease of the patellofemoral joint. It is an important cause of patellofemoral softening or patellofemoral joint osteoarthritis.

Post-knee pain syndrome refers to post-knee pain caused by lesions in the soft tissue after the knee. Frequent calf flexion and extension activities, such as swimming and kicking, tend to cause lesions at the beginning of these muscles and cause pain in the back of the knee.

Pain after sputum: The general symptoms of patellofemoral articular cartilage injury, the most important is post-tarnea pain. In the active or semi-squatting position, the initial stage is acid deficiency and discomfort, and later develops into persistent or progressive soreness. Often the pain is obvious at the beginning of the activity, the activity is relieved, and the pain is aggravated at the end of the activity or at rest.

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. Pain in front of the knee, especially near the patellar ligament.
