Cartilage Destruction of the Knee Due to Partial Meniscal Resection
Partial meniscal resection of the knee is the most frequent arthroscopic procedure. Statistical evaluations show that in more than 70% of the cases there is an isolated lesion of the posterior horn, due to trauma or degenerative changes. With sufficient arthroscopic skill, adequate equipment and appropriate instruments only the flap or damaged part is removed leaving a smooth and stable rest. We try to preserve as much meniscal tissue as possible and avoid damage to the cartilage of the femoral condyle or tibial plateau. Tears in the white/white or red/white area lacking healing potential, or painful degenerative tears are indications for resection. There is a biomechanical idea that mobile flaps or frayed edges may cause cartilage destruction due to interposition and shear motion. Reports about clinical outcome of the articular cartilage after meniscal resection are controversial.
