Symptoms of knee chondroma usually include pain, limitation of movement, and bone deformity. 1. Pain: When the size of knee chondroma continues to increase, it will compress the nerves of the knee joint, resulting in knee joint pain. 2. Restricted movement: As the chondroma compresses the nerves and blood vessels in the knee joint, the joint cannot be straightened or bent freely, which may cause symptoms of restricted movement. 3. Bone deformity: Chondroma of the knee can also affect the growth and development of bones, reduce the density of bones and lead to bone deformity. In severe cases, patients may suffer from bone fracture. It is recommended to go to the hospital in time and follow the doctor’s instructions, complete the relevant examinations and carry out the relevant treatment.
