[Arthroscopic evaluation and treatment of the disorder resulted from open meniscectomy of the knee].

Between 1989 and 1994, twenty four cases of knee disorders caused by open meniscectomy had undergone the second operation by arthroscopic procedures. The results of retrospective study indicated that main reasons of early disorders following meniscectomy were locking of remanent posterior horn, tears of remanent meniscus and injuries of fat pad and the cause of late disorders were single compartment osteoarthritis and genu varum/valgum caused by meniscectomy. In early cases, the arthroscopic reshape or removal of meniscal remanents and partial resection of fat pads could get satisfactory results. In late cases of osteoarthritis with genu varum/valgum, arthroscopic debridement, high osteotomy of tibia or knee replacement should be carried out as means of treatment.
