It is special to roll over position, is located in articular cavity.Anterior cruciate ligament depends on the relaxation that fracture often results in ACL, joint instability, patient's subjectivity
Show as pain and limitation of activity；If being not treated in time, joint will appear flexion contracture, seriously affect kneed function.It should
Classification of fracture is more common in Children and teenager, and in recent years due to the development of nationwide fitness programs and universal, adult prevalence rate is also in
Rise year by year trend.
Avulsion fracture is depended on for ACL tibial plateau, clinical imageology inspection prompts avulsion fracture block to shift more than 3mm,
It is recommended that the fixed treatment method of anatomical reduction under row arthroscope (such as: the binding of nonabsorable suture or screw are fixed).For fresh
Avulsion fracture block diameter of depending on be more than or equal to depending on for 2 pieces or more or oldness less than 10mm or number of blocks of fracturing
Avulsion fracture, we advocate to select nonabsorable suture (such as: No. 5 lines of ETHICON), will be fractured by arthroscope tunneling technique
Block is fixed on proximal ends of tibia.Since the type fracture is more common in teenager, since teenager's epiphysis is not yet closed, therefore screw is used
Fixed form treatment has some limitations and technical requirements, and clinically we advocate to stitch using identical nonabsorable at present
Line fixed form.Sclerite is depended on using nonabsorable suture (such as: No. 5 lines of ETHICON) fixed ACL, arthroscope tunnel need to be passed through
