Abstract Partial 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. Post-meniscectomy OA of the knee is generally believed to be a consequence of bio mechanical alterations at the knee due to the absence of a meniscus to distribute the joint reaction force. Multiple Previous radiographic changes used to assess the disease status of the knee have limited the capacity to directly evaluating the articular cartilage and to identify the early effect of meniscectomy on the knee articular cartilage and subchondral bone. MRI, with its excellent soft-tissue contrast, is the best imaging technique currently available for the direct assessment of the articular cartilage. Conventional MRI sequences alone do not provide a comprehensive assessment of cartilage. So that in our work we included a cartilage sensitive sequence in addition to the conventional sequences. The present study was conducted on 22 patients their ages ranged between 20 and 45 years with a mean age (33.5 years).All patients had arthroscopically normal articular cartilage at the time of initial meniscectomy Including 16 males (72.7%) and 6 females (27.3%).sixteen patients had APMM, five patients had APLM and one patient had posterior horn medial meniscus repair. All patients were examined by conventional MRI as well as cartilage sensitive (DESS) sequence at a minimum follow up period of 6 months post surgery. |
