2. Representative pressure mapping demonstrating the contact area and pressure distribution in the lateral and medial compartments of specimen 7 (a left knee) at 30° of flexion for the eight lateral meniscus conditions.
Representative pressure mapping demonstrating the contact area and pressure distribution in the lateral and medial compartments of specimen 7 (a left knee) at 30° of flexion for the eight lateral meniscus conditions. The diamond shows that the distribution of pressure between the medial and lateral compartments of the knee was equal.

3. Location of the tears at the site of the posterior root attachment of the lateral meniscus of a right knee.
Location of the tears at the site of the posterior root attachment of the lateral meniscus of a right knee. From left to right, the four tears are footprint tear, root avulsion, and radial tears at 3 and 6 mm. ACL = anterior cruciate ligament, PCL = posterior cruciate ligament, LTE = lateral tibial eminence, and MTE = medial tibial eminence.

Figs. 3-A and 3-B Schematic showing an in situ suture repair of the posterior root attachment of the lateral meniscus of a right knee. ACL = anterior cruciate ligament, and PCL = posterior cruciate ligament. Fig. 3-A Posterior view showing a root avulsion. Fig. 3-B Anterior view showing how two horizontal mattress sutures were secured into the meniscus, pulled anteriorly with the use of an eyelet pin, and tied over a button on the anteromedial proximal aspect of the tibia.

5. Overall effect of each lateral meniscus condition on contact area in the lateral compartment when pooled across all flexion angles.
Overall effect of each lateral meniscus condition on contact area in the lateral compartment when pooled across all flexion angles. The error bars indicate the standard error of the mean. *P < 0.05 compared with the intact condition. +P < 0.05 compared with the corresponding tear condition.
