Twenty cases of chronic anterior cruciate ligament insufficiency not responding to conservative treatment and having disabling functional instability, a positive pivot shift test were undertaken for anterior cruciate reconstruction using semitendinosus musculo-tendinous unit as a dynamic ligament. Average follow up was one year and six months (range 10 to 50 months). Using modified scoring system of Marshall et al based on 16 parameters and total 50 points for a normal knee, 90 per cent patients obtained excellent to good results; while 10 per cent had fair result. The procedure is advantageous, because the new dynamic ligament with musculo-tendinous pedicle graft with preserved vascularity and innervation provides proprioceptive pathways thus avoiding excessive stretching. The procedure needs fixation at distal point only, which is technically easy and very secure.
