Patient: Description of condition (onset, main symptoms, hospital visited, etc.): The other day, I was too active and had knee swelling and pain, and walked with a limp. My knee was swollen and painful a few times, but I got better after resting for a while, and I walked and jogged normally without any problems. 2. Can you give me any treatment advice? Hospital specialist: The horizontal tear of the anterior horn of the meniscus caused extravasation of joint fluid into the prepatellar bursa, resulting in inflammatory changes of the bursa. If the symptoms persist or worsen, arthroscopic meniscus suture treatment can be considered. Patient: Thank you for your busy reply! The other day, I bought two aerosols from the pharmacy to activate blood circulation and remove blood stasis. After using them for a few days, the swelling in my knee joint has basically gone down, and I have no problem walking normally, and I don’t have any pain anymore. I would like to ask you a few more questions: 1. What degree of damage is my meniscus? 2. Is it possible to heal with conservative treatment? Hospital Specialist: Conservative treatment is possible, good luck for a speedy recovery. Patient: Thank you for your reply!
