Meniscal injuries can be determined by an MRI of the knee joint to determine the extent of the injury. If the meniscal injury is more severe, minimally invasive surgery may be an option. The main procedure is an arthroscopic partial meniscectomy or suturing of the meniscus. The surgery usually takes about 1 hour. It mainly depends on whether the meniscus injury is located in the posterior horn, body, or anterior horn of the meniscus. If it is in the posterior horn, the surgery is more difficult and may take longer. The recovery time after minimally invasive meniscus surgery is also 2-3 months. Pay attention to more rest and try to avoid walking long distances and excessive knee flexion to help repair the meniscus injury. You can spray some local swelling and pain aerosol to activate blood circulation and remove blood stasis, which also helps recovery.
