Total knee arthroplasty (TKA) identified as an effective treatment for ultimate knee joint disease can effectively relieve pain, correct deformity, improve knee function and enhance the quality of life of patients. Patient satisfaction has been increasingly considered as an important factor in evaluating the success of primary TKA. Anterior knee pain that usually appears in the region of the anterior knee is a recognized complaint for primary TKA and has a strong impact on the improvement of knee function and patient satisfaction of primary TKA. ⋯ However, none of the past treatment such as patellar resurfacing, patellar denervation without patellar resurfacing or a mobile-bearing prosthesis has a good and affirmative effect on it. The prevention and treatment of anterior knee pain following primary TKA still is a difficult solved problem. To address this problem, we need further researches about the cause of anterior knee pain, knee joint prosthesis and biomechanics of patellofemoral joint, as well as lots of randomized controlled trials.

Compared with open surgery, percutaneous transforaminal endoscopic discectomy (PTED) for lumbar disc herniation (LDH) has advantages of minamilly invasive, little impact on stability of spine and rapid recovery. However, PTED by transforaminal approach has relatively limited indications and can not completely replace open surgery, due to different location of migrated herniated fragment, the level of pathological segment or presence of a high iliac crest. ⋯ However, not-standard manipulation, improper selection of indications or surgical approach has been attributed to the main reason for failure in PTED surgery. In view of this, the paper summaries indications, different approaches and methods, clinical efficacy and complications of PTED.

Discogenic low back pain is the common type of chronic low back pain. However,its mechanism has not been completely clarified. ⋯ The paper summarizes the mechanism of neurotrophins on discogenic low back pain according to the pain transfer pathway of neurotrophins in intervertebral disc, dorsal horn ganglia and spinal trigeminal nucleus. Changing the pain transmission by regulating neurotrophins and its receptor will provide a new way for the treatment of discogenic low back pain.

Review Meta Analysis
[Pulsed electromagnetic field therapy for the treatment of knee osteoarthritis: a systematic review].
To evaluate the clinical effectiveness of pulsed electromagnetic field therapy in the treatment of knee osteoarthritis. ⋯ The effects of Pulsed electromagnetic field therapy for treating knee osteoarthritis need more powerful trails to be confirmed. The above conclusions still need more high-quality randomized controlled trails to be verified owing to the limitations of the number and the quality of systematic review included studies.
