In acute injuries to the posterior horn of the medial meniscus of the left knee, a long-legged plaster brace can be used for four weeks, and those with blood and fluid accumulation can be aspirated under local anaesthesia and then bandaged with pressure.
After the pain has subsided, quadriceps exercises can be performed to avoid muscle atrophy. Those whose symptoms cannot be eliminated consider surgical treatment, including total meniscectomy, partial meniscectomy, meniscal repair, and allograft meniscal transplantation, etc. Again, post-operative rehabilitation should be performed under medical supervision.
