OSTEOARTHRITIS OF THE KNEE FOLLOWING MENISCECTOMY

Abstract
The relationship between age at meniscectomy and the time to developing OA requiring an operation was studied. A total of 63 patients (7.8% of those presenting for an operation for OA) had had a previous mensicectomy. It was found that there was a strong correlation between the age at meniscectomy and the time delay (r = −0.68, P35 yr old with a mean delay of 9.8 yr (95% CI 7.5–12.2). The development of OA requiring an operation following meniscectomy depends on the age at meniscectomy and the time delay. To show an increase rate of OA following meniscectomy in a young population would require follow-up of at least 26 yr.
