[Repeat arthroscopy]

Repeat arthroscopy was done in 82 patients from 1984-1988 (2.5%) 18 months after the first arthroscopy. Eighteen of the repeat arthroscopies were planned operations, 35 were necessary due to continuous complaints, and 20 were done because of new complaints. Nine were done after a new accident. In 4 cases, at repeat arthroscopy a meniscus remmant was excised that had been insufficiently treated at the first operation. In four cases, a new meniscal lesion had occurred. An extension lag after ACL reconstruction was another reason for repeat arthroscopy. In those cases sometimes a synovial tumor in the intercondylar notch was excised. In these repeat arthroscopies, 84% were done by the two most experienced arthroscopists in the department.
