In 3,126 arthroscopies of the knee 82 menisci were sutured by the inside-outside-technique. 52 patients were followed up. 42 patients had no or small disabilities. In 10 patients we performed a rearthroscopy. The suture of the meniscus includes more social and economic problems then the partial meniscectomy. It's well known, that the menisectomy induces arthrosis, and so should be tried to suture possible tears of the meniscus.
