Meniscal thickening of the knee occurs when a patient develops a hyperplasia of the meniscus of the knee. If this phenomenon occurs clinically, the specific treatment will be different depending on the patient’s clinical presentation. If the patient feels pain in the knee joint after this condition, there is pain when going down the stairs, and occasionally there is strangulation and gastrointestinal phenomenon. If the patient’s knee movement is basically normal, the patient can be treated conservatively by reducing the amount of activity and resting in bed. In addition, the knee joint can be treated with topical ointment for blood circulation and stasis removal, or with Chinese herbal fumigation, or with intra-articular injection of sodium vitrate, which can nourish the cartilage. If the patient has a thickened meniscus, and feels local pain, frequent locking and gastrointestinal phenomenon, which affects the flexion and extension of the knee joint. In this case, the treatment can be surgical. Minimally invasive surgery can be performed through knee arthroscopy to repair the meniscus.
