Research advances on tendon-bone healing in anterior cruciate ligament reconstruction / 中华骨科杂志

ABSTRACT

Rupture of anterior cruciate ligament (ACL) is a common sports injury.It will cause knee osteoarthritis because of joint instability and acceleration of degenerative changes after injury.Arthroscopic reconstruction with a tendon graft is a common procedure to achieve function recovery.A series of histological changes and structural modification happened between the tendon and bone tunnel after ACL reconstruction and complete tendon-bone healing was achieved finally.A number of factors affects the healing process which determined the long-term result of the treatment.Published literatures reported that about 11％-32％ patients underwent ACL reconstruction were not satisfied with the results and 10％ of them required reoperation.Studies on the tendon-bone healing have long been a research hotspot in sports medicine.Controversy still remains not only on the fundamental healing process but also on the stimulating factors despite of a large amount of researches on its physiological basis,influencing factors,et al.This article provides a review of the basis and influence factors of the healing process,and summarizes the methods to accelerate the process of tendon-bone healing.
