Abstract: BACKGROUND: Arthroscopic reconstruction of posterior cruciate ligament has become the main treatment for severe injury of posterior cruciate ligament. Mastering the characteristics of all kinds of posterior cruciate ligament reconstruction grafts and selecting suitable transplantation materials are considered to be an important link affecting the effect of posterior cruciate ligament reconstruction.  
OBJECTIVE: To summarize the advantages and disadvantages of autografts, allografts and artificial ligaments in posterior cruciate ligament reconstruction, and put forward improvement strategies and prospect.  
METHODS: The first author searched the articles about implant materials (autografts, allografts and artificial ligaments) for the reconstruction of posterior cruciate ligament on PubMed database, CNKI database and Wanfang database from 2000 to 2020. The articles obtained in accordance with the search words were screened and retained, and the relevant articles related to the analysis of the advantages and disadvantages of all kinds of posterior cruciate ligament grafts were further analyzed and summarized in detail.  
RESULTS AND CONCLUSION: Posterior cruciate ligament reconstruction grafts have their own advantages and disadvantages. At present, autogenous hamstring tendon grafts are most widely used in clinic. Ligament enhancement device, internal tension reduction technique or tendon surface coating technology can improve the effect of posterior cruciate ligament reconstruction. Autogenous tendons, allogeneic tendons and artificial ligaments are all important sources of posterior cruciate ligament reconstruction grafts in the short term. With the progress of artificial ligament and tissue engineering ligament research in the long term, it is expected to completely solve the problem of posterior cruciate ligament reconstruction materials. When selecting posterior cruciate ligament grafts, surgeon should consider the level of activity expected by patients, the types of activities they participate in, their professional characteristics, the reconstruction techniques and habits mastered by doctors, and the fixed materials matched with the grafts, so as to select a suitable posterior cruciate ligament reconstruction graft.
