Discussion of Results


I found that my hypothesis was correct. It seems as if freeze-drying the meniscus does not effect the strength of the material. Both the controlled meniscus and the freeze-dried meniscus had the same damage. This damage was very miner, for the scratches only eceeded the length of 1 1/8-mm, which did not cause any problem to the structure of the meniscus.

The inner and outer portions of the menisci were damaged more than the middle portions. The middle section of the meniscus is thicker; therefore, it is more stronger and is able to endure more impact. Although the inner and outer portions of each meniscus was damaged the damage was very small. The scratches on each side of the menisci were not very deep, and seemed to not effect the durability of the cartilage.

It seems as if both menisci successfully withstood the impact of the experiment. The intervals of impact were very intense.The intervals consisted of 3 quick drops onto the meniscus, and repeated three more times before the test was over. Therefore, the menisci actually endured 36 drops in total before the 12 tests were done.

I believe that the risk of allografting in the knee is a good risk to take. The surgery is not too difficult, and it seems as if the new meniscus will be equally as strong as the original. People should consider this procedure if the damage to the original menisus is beyond repair.
