Results of partial meniscectomy related to the state of the anterior cruciate ligament. Review at 20 to 35 years.
We reviewed 195 knees in 167 patients at least 20 years after a rim-preserving meniscectomy. They were considered in two groups: 102 knees had had an intact anterior cruciate ligament (ACL), and 93 had had an unrepaired rupture. More patients with a ruptured ACL had downgraded their sport activity by five years after meniscectomy. The incidence of radiographic osteoarthritis was about 65% at 27 years in patients with a ruptured ligament, and 86% in those followed up for over 30 years. In the ligament-deficient group 10% had had operations for osteoarthritis, and another 28% had had other operations, mainly further meniscectomies. Only 6% of those with an intact ligament had needed a second operation after meniscectomy and at long-term follow-up 92% of them were satisfied or very satisfied. Only 74% of the ligament-deficient patients were satisfied with their result. The long-term outcome after rim-preserving meniscectomy depends mainly upon the state of the anterior cruciate ligament.
