Chondromalacia patella and patellar tendonitis are both knee joint pathologies that can cause symptoms such as localized pain and limited movement. They can be treated with medication, physical therapy, surgery and other treatments. 1. Chondromalacia patella: It is the symptom of chondrocyte detachment, osteomalacia, and narrowing of joint space in the patella caused by developmental disorder of patella, excessive labor or improper posture of movement. (1) Drug treatment: non-steroidal drugs such as diclofenac sodium cream can be applied externally to relieve the local pain symptoms, or oral ibuprofen, meloxicam and other drugs to relieve pain. (2) Surgery: patients with severe joint injury and clinical symptoms can choose surgery, such as ligament transfer, osteotomy, etc., to fundamentally remove the cause of chondromalacia patella. (3) Physical therapy: Ultrashort wave, pulse therapy and other physical therapy methods can be chosen to promote blood circulation and reduce pain symptoms. 2. Patellar tendonitis: the tendon connecting the patella to the tibia of the lower leg is damaged or inflamed, and the continuous development of chondromalacia patella can also lead to patellar tendonitis. (1) Medication: Non-steroidal anti-inflammatory and analgesic drugs such as aspirin and ibuprofen can be used to relieve pain symptoms and promote inflammation absorption. You can also carry out pain point closure treatment, injection of glucocorticoids, procaine and other drugs, to play a good pain relief effect. (2) Physiotherapy: Physiotherapy methods such as ultrashort wave can be chosen to promote inflammatory absorption and reduce pain symptoms. If the above diseases appear, you should consult the doctor in time to standardize the treatment, and the above medication should be carried out in accordance with the doctor’s instructions.
