The authors have put together their experience of the long-term results after meniscectomy. They came to the following conclusions: 1. A knee joint does not become unstable after removal of a cartilage unless there is another connected lesion. 2. X-ray modifications are to be found on the majority of the patients after meniscectomy, but very often without any clinical sign. 3. The sooner meniscectomy is practiced the better the long-term results are to be expected. 4. A good operative technique is most important to get satisfactory long-term results.
