Herniated lumbar discs and knee osteoarthritis, there is no such thing as a good cure, and some relief can usually be achieved with conventional treatments such as general therapy, physical therapy, medication, and surgery. For lumbar disc herniation, non-surgical treatments such as life management, physical therapy, and medication are usually the mainstay for patients with mild symptoms and a short course of the disease. For patients for whom non-surgical treatments are ineffective, minimally invasive techniques and open surgical treatments are available depending on the condition. The treatment of knee osteoarthritis is graded and personalized according to the patient’s gender, age, weight, personal physical quality, and lesion location, and is divided into four levels: basic treatment, drug treatment, restorative treatment and reconstructive treatment. The majority of patients with lumbar disc herniation usually have a good prognosis after conservative treatment. If conservative treatment is ineffective, surgical treatment can be considered. Knee osteoarthritis is a chronic disease that progresses gradually. After standardized treatment, the disease can be alleviated, symptoms can be reduced, and good knee function can be maintained, and end-stage patients can undergo surgical treatment, and most of the patients can have a normal work and life after the surgery.
