Articular cartilage changes following meniscal lesions. Repair and meniscectomy studied in the rabbit knee

Acta Orthop Scand. 1991 Aug;62(4):319-22. doi: 10.3109/17453679108994461.


A well-defined, longitudinal lesion in the avascular part of the medial meniscus of the right knee was made in 30 rabbits. After 3 months, the lesion was repaired surgically in 12 rabbits, was untreated in 12 rabbits, and a meniscectomy was performed in 6 rabbits. The articular cartilage was studied macroscopically and microscopically at 3-month intervals. Cartilage changes 3 months after meniscectomy were more pronounced than after meniscal repair or than in untreated lesions. However, meniscal repair did not reverse the cartilage changes.
