| Abstract: | Results of 150 arthroscopic partial medial meniscectomies were analyzed by computer to identify the factors that lead to an unsatisfactory (fair or poor) outcome. The average follow-up for the group was 36 months (range 24-60 months). One-hundred ten men and 40 women were involved, with an average age of 48 years. The overall results were 58% excellent-good, 28% fair, and 14% poor. Most tears involved the posterior horn (76%). Bucket handle, longitudinal, and flap tears were rated 88% excellent-good, whereas horizontal cleavage and degenerative and complex tears had only 45% excellent-good scores. The results were adversely affected by the severity of the chondromalacia, work-related injury, prior knee surgery, simultaneous lateral meniscectomy, and increased knee laxity. Because degenerative posterior horn tears had such a high percentage of unsatisfactory results, the question remains as to whether all these tears need to be removed. |
