Study Of The Clinical Outcome Between Traumatic And Degenerative Meniscal Tears After Arthroscopic Surgery:a 4 Years Follow Up Study

Purpose:The aim of this study is to evaluate the difference of clinical outcome between traumatic and non-traumatic (degenerative) meniscal tears after arthroscopic surgery. Results from the study can be use by orthopaedic surgeon as reference in the choice of the optimal course of management for meniscal tears.Methods:One hundred and seventeen patients met the criteria of inclusion for the present study. Patients were divided in two groups T and NT according to the presence of distinct previous traumatic events to the knees. Two subgroups were formed in each groups T and NT respectively at a mean follow up of 1 and 4 years. Postoperative Clinical outcome were assessed using Lysholm scores and Rand SF-36 survey.Results:one hundred and seventeen patients were included in the present study with 60(51.28%) patients in the traumatic group and 57(48.71%) in the degenerative group.95(81.19%) patients in total were satisfied with their health status at end of follow up. The mean value of lysholm scores at 1 year were respectively 85.25±8.78 for traumatic group and 86.38±12.14 for non-traumatic group and at 4 years were respectively 92.63±7.31 for traumatic group and 72.90±20.77 for non-traumatic group. According to Rand SF-36 health, traumatic group showed better Improvements compare to non-traumatic group between 1 and 4 years after arthroscopic meniscus surgery.Conclusion:95(81.19%) patients in total were satisfied with their health status at follow up, however, we found that Arthroscopy as a treatment for meniscal tear have a relatively better mid-term clinical outcome for traumatic meniscal tears than for non-traumatic/degenerative meniscal tears.
