Abstract:
ObjectiveTo retrospectively determine the prevalence of Ramp lesion (the peripheral attachment of the posterior horn of the medial meniscus) of the posterior horn of the medial meniscus with concurrent anterior cruciate ligament(ACL) ruptures and analyze the relevant risk factors.MethodsFrom April 2002 to October 2007,868 consecutive knees were diagnosed as ACL injury and received arthroscopic surgery for ACL reconstruction(ACLR).All the patients were verified for the tears of Ramp area under arthroscopy.The prevalence of Ramp lesion was evaluated respectively.Then all cases were divided into different groups depending on the time interval from ACL injury to ACLR (TFI) and other relevant risk factors as age and gender.ResultsAmong 868 knees underwent surgery for ACLR,144 knees were diagnosed as Ramp lesion.The average age was 24.7 years,113 males,31 females.The mean TFI to ACLR was 29.3months.The prevalence of Ramp lesion was 16.59％,which was analyzed as logarithmic correlation with TFI.Patients younger than 30-year old and male patients had significant higher prevalence of Ramp lesion.ConclusionRamp lesion is a common meniscus injury that can occur at the time of ACL rupture or as a result of knee laxity associated with ACL insufficiency.The prevalence of Ramp lesion is 16.59％ which increases with time until 24 months after initial injury.Patients younger than 30-year old and male patients have higher prevalence of Ramp lesion.
