Arthroscopic partial meniscectomy: A long‐term follow‐up

A follow-up study was conducted to clarify the clinical and radiological long-term consequences of arthroscopic meniscus resection. One hundred thirty-six patients who had unilateral arthroscopic resection of an isolated meniscal tear attended for an interview and a physical and radiological examination. Follow-up averaged 8.5 years, with a range of 7.9-11.6 years. The reoperation rate was as high as 22.8%, but was the lowest in the bucket handle tear group (13%). Pain after exercise was less frequent among patients treated for a bucket handle tear compared to other lesions. Fifty-three percent of the patients had at least one of the Fairbanks change in the operated knee and only 22% in the control knees. The radiographic result was not influenced by the type of meniscus lesion nor were high age or intraoperatively described cartilage damage factors of significance. Malalignment less than 4 degrees of valgus and greater than 10 degrees of valgus was found to be a significant risk factor for the development of degenerative changes following meniscus resection.
