Autograft meniscus replacement: experimental and clinical results.

Because of the risks related to allograft meniscus replacement an attempt was made to replace the medial meniscus by autograft tissue. In animal experiments the free middle third of the patellar tendon was transformed to a meniscus-like structure within one year after insertion. Early arthroscopic results after autograft meniscus replacement in a clinical series comprising 20 patients are promising.
