Introduction: The meniscus is a biconcave fibrocartilage in the knee joint interpose between the femoral condyles and tibial plateau; the meniscus has functions in load bearing, load transmission, shock absorption joint stability, joint lubrication, and joint congruity.
Aim: The aim of this study is to provide orthopeadic surgeon a base of reference in the choice of the optimal course of management for meniscal tears.
Materials and 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: A total of 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 compare to non-traumatic/degenerative meniscal tears.
