Objective To investigate the clinical effect of radiofrequency for gluteal muscle contracture under arthroscope.Methods 12 patients with gluteal muscle contracture treated by arthroscopy in our hospital from June 2015 to December 2018 were selected as the research objects. According to Liu Yujie's classification of gluteal muscle contracture, there were 6 cases of strip type, 3 cases of fan type, 2 cases of mixed type and 1 case of tensor fascia lata contracture. The contracture band was released by radiofrequency under arthroscopy until flexion, adduction and internal rotation disappeared. The curative effect was evaluated by comparing the quantitative score of gluteal muscle contracture function, the hip movement score (HOS-sport) and the hip daily life score (HOS-ADL) before and after operation. Results Local hematoma occurred in 2 cases after operation, and was absorbed 2-3 days after local pressure bandage; There was no incision infection and sciatic nerve injury; The average followup time was (17±97) months; At the last follow-up, the quantitative score of gluteal muscle contracture, HOS sport score and hos ADL score were significantly higher than those before operation.ConclusionArthroscopic treatment of gluteal muscle contracture has the advantages of less trauma, safe operation and reliable curative effect.
