For medial posterior horn meniscus injuries, the treatment options include conservative treatment or surgery depending on the degree of injury.
1. Conservative treatment: For simple meniscus injury, if the length is less than 5mm and it is stable marginal tear or stable longitudinal meniscus tear, conservative treatment can be adopted, and the specific measures are knee braking and rehabilitation exercise.
Knee braking can be fixed by plaster or brace, generally fixed for 4~6 weeks, and at the same time, isometric contraction of thigh and calf muscles can be performed to maintain muscle tone.
2. Surgery: For the ineffective conservative treatment or serious instability injury, timely surgery should be performed. At present, most of the meniscus surgeries can be performed under minimally invasive arthroscopy, such as partial meniscectomy, meniscus suture repair, etc. Complete removal of the meniscus is easy to be performed in the knee. Complete removal of the meniscus is likely to induce osteoarthritis in the later stages, so complete removal should be cautious.
For medial posterior horn meniscus injuries, it is recommended to consult a doctor as soon as possible, so that the doctor can evaluate the condition and decide the specific treatment plan.
