[Arthroscopic notch-plasty in persistent extensor deficit following anterior cruciate ligament-plasty].

Occasionally following ACL reconstruction, an extension deficit persists, because of impingement of the transplant in the notch. In six cases an arthroscopic notchplasty was performed, five of these cases were immediately successful. Due to initial insufficient resection of the notch, one patient required a second notchplasty to achieve full extension.
