Posterior horn degeneration of the medial meniscus is a mild injury that is usually treated symptomatically. Posterior horn degeneration of the medial meniscus begins with braking and reducing knee activity to prevent increased activity from aggravating symptoms. If pain occurs, ibuprofen can be given to relieve pain, and ointments that activate blood circulation and remove blood stasis and relax tendons and collaterals can be given to promote blood circulation, such as blood-relieving and pain-relieving ointment and Yunnan Baiyao ointment. Acupuncture and massage can also be given. All of the above medicines and ointments should be used under the guidance of a doctor.
