It has long been felt that this condition was not prone to occur in the aging and that symptoms in the older patient were invariably due to the simultaneous presence of osteoarthritic changes, generally demonstrable by x-ray when these patients appear for evaluation.

Recently, it has been emphasized that the elderly patient can also have attritional meniscus ruptures secondary to the osteoarthritis with typical signs and symptoms of derangement.1 It is the authors' purpose to illustrate that traumatic internal derangements of the knee are not uncommon in the aging, are clinically similar to derangements found in younger patients, and with minor modifications in surgical technique, can
