Abstract
Ange, six to sixteen years) at the time of the operation and twenty-eight years (range, twenty to thirty-six years) at the time of follow-up. The average duration of follow-up was seventeen years (range, eight to twenty-eight years). The primary indication for the meniscectomy was continuing pain in fourteen knees and locking or snapping in three. One patient had tenderness and walked with a limp. A meniscal tear was found in twelve knees at the time of the operation. According to the scale of Ikeuchi, the result was excellent for ten knees, good for three, and fair for five. Of the five patients (five knees) who had a fair result, four had mild intermittent discomfort after strenuous physical activity as well as clicking (three knees) or swelling (one knee), and one had clicking. One of these five patients was subsequently found to have rheumatoid arthritis, and two subsequently had a patellar realignment. No degenerative changes were evident on the roentgenograms of the eight patients (nine knees) for whom they were made at the latest follow-up evaluation. We retrospectively reviewed the results for fifteen patients, eight girls and seven boys, who had had a total of eighteen meniscectomies performed for a discoid meniscus at The Hospital for Special Surgery between January 1, 1955, and December 31, 1983. The average age was ten and a half years (range, six to sixteen years) at the time of the operation and twenty-eight years (range, twenty to thirty-six years) at the time of follow-up. The average duration of follow-up was seventeen years (range, eight to twenty-eight years).
