Abstract: BACKGROUND: Research evidence shows hip arthroplasty has become the final treatment of osteonecrosis of femoral head, but early- and middle-stage osteonecrosis of femoral head or young patients often give priority to hip preservation treatment, including conservative treatment and surgical treatment.
OBJECTIVE: To summarize the progress of hip preservation in the treatment of osteonecrosis of femoral head.
METHODS: The literature about hip-preserving treatment of osteonecrosis of femoral head in PubMed, VIP, CNKI and Web of Science databases from 2010 to March 2020 was searched by computer. The key words were “osteonecrosis of femoral head, hyperbaric oxygen, pulsed electromagnetic fields, extracorporeal shock wave, hip arthroscopy, core decompression, stem cell transplantation, non-vascularized free bone grafting, vascularized free bone grafting, porous tantalum rod implantation, intertrochanteric osteotomy, medication”. A total of 197 articles were retrieved, and the full text was consulted. According to the inclusion criteria, 59 articles were included for result analysis. 
RESULTS AND CONCLUSION: (1) Drug therapy should be used cautiously because of its potential side effects and insufficient research. (2) Physiotherapy is effective for early lesions, and it has the advantages of non-invasion and convenient operation. (3) At present, there are different types of hip preservation surgery. Core decompression is the basic therapy for the treatment of osteonecrosis of femoral head, but it is seldom used alone. At present, it is often treated in combination with other hip preservation therapies. Osteotomy has higher requirements in the selection of patients’ indications and surgical skills, so it should be chosen carefully in clinic. There are some problems in porous tantalum rod implantation, such as long operation time, large blood loss and difficulty of hip replacement in the later stage. Stem cells and arthroscopic therapy show good results, and the research process should be accelerated. Vascularized bone grafting has a good effect on both middle- and late-stage patients.
