Glutealmuscles contracture (GMC) is a common disease caused by the fibrosis of the gluteal muscles and their fascia, resulting in abnormalities in hip abduction and external rotation, with abnormal squatting, sitting and walking postures as clinical features. The main manifestations of the disease are walking in an outward-looking position, not being able to cross the legs, not being able to squat with the legs together, and possibly bouncing at the hip joint. The effect of conservative treatment for this disease is not certain, and once diagnosed, surgery should be performed as soon as possible. Although the traditional open surgery is effective, it is more traumatic and bleeding, and the postoperative exudation is more frequent, which can easily lead to hematoma and infection and affect the wound healing; meanwhile, due to the heavy postoperative pain, it is difficult for some patients to perform effective functional exercise, which also affects the efficacy of the surgery. Since 2008, the arthroscopic treatment group of our department has been performing arthroscopic release of gluteus contracture using plasma radiofrequency technology, and has achieved satisfactory results. This method has the advantages of less trauma, faster recovery and less pain. Meng Chunqing, Department of Orthopedics, Wuhan Union Hospital This minimally invasive surgical method requires only two small 0.5cm incisions and is able to perform a complete release of the contracted tissues. It also has good surgical results for severe contractures because it can be released under direct vision under arthroscopic surveillance, which is safer and more complete than the release of open surgery. Because of the small incision and the ability of the plasma device to stop bleeding at the same time as the release, postoperative patient pain is minimal and hematomas are less likely to form, which is incomparably superior to open surgery. More importantly, since most patients with gluteus contracture are scarred, the large incisions of open surgery can cause large scars and affect the appearance. Arthroscopic release is a minimally invasive procedure with a very small incision scar, which is a true cosmetic incision, and is the preferred method for those patients who have high demands on appearance.
