Abstract
Meniscectomy is a common surgical procedure used to treat a symptomatic meniscal tear. Meniscectomy has been recognized as an important risk factor for tibiofemoral osteoarthritis (OA). (13,109-111)
Quantitative magnetic resonance imaging (qMRI) allows visualization of all knee tissues, with superior assessment of early structural change associated with the development of knee OA. (21,22,73,113)
Our aim in this study was to identify whether patients who had previously undergone meniscectomy six months earlier, exhibited morphological differences in tibiofemoral joint articular cartilage assessed by quantitative MRI compared with pre meniscectomy status and healthy controls. Also for evaluation of clinical outcomes following meniscectomy.
Twenty patients were included in the study, who were admitted to El-Hadara Orthopedic and Traumatology University Hospital and Gamal Abdel Nasser Health Insurance Hospital, Alexandria, Egypt, suffering from isolated tears of medial or lateral menisci. On admission all patients were assessed by history taking, clinical examination and radiological assessment. They were diagnosed as having torn medial or lateral meniscus and the articular cartilage volume of tibiofemoral joint was assessed by quantitative MRI.
In this study the age of the patients ranged from 24 to 57 years with a mean of 37.55 ± 9.50 years. There were nineteen (95%) males and one (5%) female. Definite history of trauma was present in all patients. The injury was in a twisting one in 16 cases (80%), falling down in 2 (10%) and road traffic accidents in 2 cases (10%). Thirteen patients (65%) had history of injury more than six months and seven patients (35%) less than six months.
All patients were operated upon by meniscectomy. Medial meniscectomy was done in sixteen patients (80%) and lateral meniscectomy in four patient (20%). They were subjected thorough radiological and clinical examination six months following meniscectomy. Also, another quantitative MRI examination was done at the end of the follow up period.
