Popliteal cysts in children are mostly congenital, which may cause knee pain, stiffness, lower extremity venous obstruction and other hazards.
1. Knee pain: with the gradual increase of popliteal cyst, it will cause some pressure on the nearby tissues, especially on the knee joint area, which will lead to obvious pain on the back side or front inner side of the knee joint.
2. Knee stiffness: popliteal cysts are usually not easy to cause joint stiffness when they are small, but with the gradual increase of the cysts, it will easily lead to stiffness of the knee joints, and even restriction of joint flexion.
3. Lower extremity venous obstruction: mainly due to the cyst is relatively large, causing serious pressure on the local, resulting in poor blood circulation in the lower limbs and caused.
Children with popliteal cysts should consult the doctor in time, follow the doctor’s instructions after the diagnosis, and pay attention to cooperate with the doctor’s care after the operation.
