Hello, I would explain that the pain in the knee could be related to a meniscal laceration.  For this reason, I would recommend performing a knee joint MRI in order to examine better the joint and discuss arthroscopy, which may be needed.  Hope I have answered your query. Let me know if I can assist you further.
