Meniscus injury leg pain is treated differently depending on the severity of the specific injury and the specific symptoms. For 1st and 2nd degree meniscus injuries diagnosed by MRI, oral glucosamine sulfate can be administered. Intra-articular injections of sodium vitreous acid can be administered into the knee cavity. Both of these treatments will help the joint cartilage and meniscus to recover. If the leg pain is severe, oral NSAIDs, such as diclofenac, can be administered. Arthroscopy is recommended if the meniscus is found to have 3rd or 4th degree damage by MRI. If the meniscus is found to be repairable after arthroscopy, the prognosis is good, and the meniscus should be repaired at the same time. If the meniscus is difficult to repair or the prognosis is not good after arthroscopy, partial or total removal of the meniscus can be performed at the same time.
