China | Prospective, Before-after | 226 patients (383 hips), | -- | 36.5 | 57/169 | -- | Progress in the staging of clinical course and collapse of the femoral head in patients with low Harris scores and Hydrops articuli. |
Before operation:68 After: 79 P<0.005 |
35 months | Excellent curative effect was found in the majority of hips. The AVNFH was improved by hip arthroscopy through scavenging pain-producing substances, removing the cartilage chips caused by isolation or undermining dissection, and correcting internal environment disorder. | |

Germany | Prospective, Before-after | 53 patients (56 hips) | -- | 44 | 39/14 | Steinberg stages I-III | No sever complication | -- | 33 months | In case of cartilage defects or potential collapse of the femoral head, arthroscopy of the hip joint was performed. The success rate was reported in 86% of patients treated with Steinberg stages I-III. | |

China | Retrospective study | 72 patients (80 hips) | HA: 41 cases/ 46 hips C:31 cases/34 hips |
Two groups were matched | -- | (stages 0, I, ) | No sever complication | -- | -- | Success rate was higher in multihole core decompression and arthroscopic debridement in the management of AVNFH, compared to the traditional group | |

16 patients with avascular necrosis | -- | 17 to 64 years. | 33%/77% | -- | No sever complication | Harris hip scores increased by 27 on average. (P<0.005) |
-- | The patients with avascular necrosis reported no pain after arthroscopy and the Harris hip scores increased by 27 on average | |

China | Prospective, Before-after |
28 patients (33 hips) | -- | 1-3 years | -- | -- | No sever complication | 85.67- 81.33 | followed up 2.5 years | Better results in patients who underwent arthroscopic core decompression combined with autogenous cancellous bone graft and BMP compared to traditional closed core decompression in terms of pain and hip function improvement, as well as slowing down the process of femoral head necrosis | |

Poland | 14 patients Prospective, Before-after | 14 patients (14 hips) | -- | -- | -- | -- | No sever complication | -- | 12 months | A good outcome was reported in the arthroscopic treatment of avascular necrosis produced at 6 and 12 months after the surgery. | |

USA | Prospective study | 23 hips | -- | -- | -- | -- | -- | -- | -- | A weak correlation was observed among the results obtained from plain radiographs, magnetic resonance imaging, and arthroscopy, indicating poor correlation among the current imaging techniques in terms of the staging of AVN. | |

USA | Prospective study | 46 patients (52 hips) | -- | -- | -- | -- | -- | -- | -- | Based on the obtained results, arthroscopy of the hip was a success in a diagnosis of osteochondral degeneration that was not detected by plain radiographs or magnetic resonance imaging. | |
