The epiphysis of tibial tuberosity is caused by the injury of juvenile tibial epiphysis pulled down by patellar tendon. It is usually manifested as local swelling and pain in the tibial tubercle, and the pain will be aggravated when the knee joint is actively flexed and extended. When squatting, the knee joint needs to bend greatly, causing pain.
Meniscus injury is caused by the patient's high intensity, trauma or incorrect strenuous activity, which can also cause pain when the patient squats. There are many reasons for synovitis, such as knee joint cooling, trauma may stimulate patients with synovitis, lead to increased arthritis secretion, lead to swelling and pain of patients' limbs, and pain when squatting. Knee joint pain after squatting should consider the following conditions: patellar ligament inflammation, knee meniscus injury, patella softening, knee synovitis. Most patients with patellar ligament inflammation are caused by fatigue or trauma, especially those who squat for a long time. When squatting, they can show pain in front of the knee and the bottom of the knee. The pain position is relatively fixed and can be touched, but it can also be manifested as knee pain when going up and down the floor.
Patients with meniscus injury are mostly caused by violence or sports wear, and patients will have specific knee pain, sometimes manifested as squat pain. Generally, the knee joint cannot be completely straightened, and the painful part may not be touched. At first, chondromalacia patellae is just a symptom of knee weakness that gradually turns into pain, which intensifies after exercise and disappears after rest. Half squat pain is a special symptom. However, the knee joint of synovitis patients will be completely straight and bent, and the painful part is generally not fixed. Athletes and the elderly, considering patients with tibial epiphysis, should pay attention to rest, and can apply local hot compress to avoid strenuous exercise, and generally will not leave sequelae for children.
