“…1,2 Meniscectomies dramatically alter the load transmission pattern across the knee, 3 with higher peak stresses, stronger stress concentration, and a decrease in the shockabsorbing capability of the joint. [4][5][6] Cartilage degeneration induced by the higher stresses is reflected in a reduction in tensile stiffness, consistent with changes in the collagen structure and proteoglycan-collagen interactions.…”

Total meniscectomies are commonly thought to cause progressive degenerative arthrosis pathology in articular cartilage in a period of a few years because of alteration of the biomechanical environment including increased joint instability. This concern has lead to a preference for partial meniscectomies, although lateral partial meniscectomies sometimes lead to catastrophic results. We performed a three-dimensional finite element model of the human tibiofemoral joint to examine the effect of lateral meniscectomy on knee biomechanics. The results were compared to those from modeling a medial meniscectomy. Under axial femoral compressive loads, the peak contact stress and maximum shear stress in the articular cartilage increased 200% more after a lateral than a medial meniscectomy. These increased stresses could partly explain the higher cartilage degeneration observed after a lateral meniscectomy. ß

Synopsis Preservation of meniscal tissue is paramount for long-term joint function, especially in younger patients who are athletically active. Many studies have reported encouraging results following repair of meniscus tears for both simple longitudinal tears located in the periphery and complex multiplanar tears that extend into the central third avascular region. This operation is usually indicated in active patients who have tibiofemoral joint line pain and are less than 50 years of age. However, not all meniscus tears are repairable, especially if considerable damage has occurred. In select patients, meniscus transplantation may restore partial load-bearing meniscus function, decrease symptoms, and provide chondroprotective effects. The initial postoperative goal after both meniscus repair and transplantation is to prevent excessive weight bearing, as high compressive and shear forces can disrupt healing meniscus repair sites and transplants. Immediate knee motion and muscle strengthening are initiated the day after surgery. Variations are built into the rehabilitation protocol according to the type, location, and size of the meniscus repair, if concomitant procedures are performed, and if articular cartilage damage is present. Meniscus repairs located in the periphery heal rapidly, whereas complex multiplanar repairs tend to heal more slowly and require greater caution. The authors have reported the efficacy of the rehabilitation programs and the results of meniscus repair and transplantation in many studies.

Implantation of a synthetic meniscal scaffold improves joint contact mechanics in a partial meniscectomy cadaver model

Meniscal substitutes should ideally distribute loads across adjacent articular cartilage much in the way of the native tissue, thereby protecting the cartilage from degeneration. The objective of this study was to quantify the loads transferred to the tibial plateau after implantation of a porous polyurethane scaffold. Our hypothesis was that scaffold implantation would improve the contact mechanics of a partial meniscectomy knee. Six sheep cadaver knees were mounted in a load-controlled knee-joint simulator. A pressure-sensor sheet, secured to the tibial plateau, dynamically recorded pressure data over 10 gait cycles for the following conditions: (i) intact, (ii) partial meniscectomy, (iii) implanted scaffold, and (iv) total meniscectomy. Implantation of the scaffold increased the contact area and decreased the contact pressures compared to the meniscal defect knee. No significant difference was found between the average and peak contact pressures of the intact knees and scaffold-implanted knees; however, contact area was significantly lower for the scaffold-implanted knees compared to intact knees. Our hypothesis was accepted; replacement with a polyurethane scaffold improved knee-contact mechanics relative to a partially meniscectomized knee. On the basis of these findings, the scaffold will be evaluated for its chondroprotective capacity in an in vivo ovine model.
